            A.  
                Functional loss may be due to an anatomical loss or to a loss of use of a part due to deformity,
                  adjesions, defective innervation, or other pathodogy. Pain may be an important factor
                  in fuctional loss, but it should be supported by adequate abnormal findings. Evaluations
                  of disability should be supported, where possible, by detailed descriptions of “range of motion” together with pertinent X-ray findings.

   382. Special Sense Organs 
   
    
   
   
      - 
         
            A.  
                Causes of Disability --Disease or injury of the special sense organs may produce disability by reduction
                  of the ability to see or hear. Loss of central vision results in inability to distinguish
                  detail and prevents reading and fine work. Loss of peripheral vision produces loss
                  of the power of orientation rendering it difficult for an individual to move about
                  freely in a strange environment. Loss of hearing impairs ability to communicate with
                  others by misinterpretation of ideas and orders and results in lack of awareness to
                  danger. The extent of impairment of sight or hearing should be determined by visual
                  or auditory testing.
                
 
 
- 
         
            B.  
                Blindness --Blindness is defined in Section 216(i) of the Social Security Act as “central visual acuity of 5/200 or less in the better eye with the use of correcting
                  lens. An eye in with the visual field is reduced to 5 degrees or less concentric contraction
                  shall be considered . . .as having a central visual acuity of 5/200 or less.” This provision relates to the freeze only and, for the purpose, a finding of disability
                  may be made without regard to individual capacity for work. An individual whose remaining
                  visual acuity or visual field is reduced to, or less than, this definition will be
                  found to have suffered statutory blindness even though he is engaging in SGA. A finding
                  of statutory blindness may not be made on the basis of an equivalent combined loss
                  of visual acuity and visual field, or a loss of visual efficiency.
                In determining whether an individual meets the statutory requirements for a finding
                  of “blindness” the reported visual acuity an visual fields must be considered in terms of the limitations
                  of the tests. Test results in the measurement of vision are not always totally reliable
                  particularly at the level where statutory blindness is concerned. The test results
                  may be influenced by subjective factors such as an individual's condition at a particular
                  time, the circumstances under which the test is performed and the type of test used
                  and do not, therefore, permit such a high degree of accuracy on repeated testing as
                  to allow usage without a rule of tolerance. Since the results of tests for vision
                  are influenced by but do not always reflect these variables, the reported test results
                  may indicate a visual field of 6 degrees, 7 degrees, or 8 degrees from the point of
                  fixation when, in fact, the visual field is restricted to 5 degrees or less, or a
                  visual acuity of 6/200 or 7/ 200 may be reported when the visual acuity is, in fact,
                  5/200 or less. Thus, a tolerance rule of 3 degrees in evaluating visual fields an
                  2 feet in evaluating visual acuity will permit a finding of “statutory blindness” when after best correction the reported test results in the better eye are a visual
                  field of 8 degrees or less from the point of fixation or a visual acutity of 7 /200
                  or less.
                
 
 
- 
         
            C.  
                Central Visual Acuity --Disability due to loss of central visual acuity may be caused by impaired distant
                  or near vision. Remaining visual acuity will usually be based on central visual acuity
                  for distance of the better eye, as corrected by regular ophthalmic lenses, using the
                  Snellen test chart. However, consideration should also be given to findings on ophthalmological
                  examination, and the record of refraction. In unusual cases, where the loss of central
                  visual acuity for distance does not accurately reflect the extent of impairment because
                  corrected near vision of the better eye is of little or no value, there may nevertheless
                  be a basis for a finding of disability depending on the facts in the individual case.
                  Such cases should be supported by measurement of near, as well as distant vision,
                  with record of refraction. (Refer to Tables No. 1 and 2, §382.11, for percentages
                  of central visual efficiency corresponding to central visual acuity notations for
                  distant and near vision.)
                Generally, reports of visual acuity will be expressed in standard terms using the
                  Snellen test chart. This permits a direct reference to the listing for visual acuity
                  in section 382.04 or to the requirements for statutory blindness in section 382B.
                  Sometimes, however, reports may reflect a reduction in the distance between the test
                  chart and the individual being tested and a reading such as 10/100 may be encountered.
                  Also, examiners will occasionally use test letters even larger than the conventional
                  20/200 size letter and report findings such as 20/800, etc. These numerical designations
                  represent the distance between the chart and the person being tested (numerator) and
                  the distance at which the letters should be seen by the normal eye (denominator),
                  These expressions of visual acuity are not mathematical fractions of visual functions
                  and cannot be compared as such; it is incorrect to reason that if 20 /20 visions equals
                  one, then 20/40 vision is only one-half as good, However, it is possible to closely
                  determine, from unusual reports of visual acuity, an individual's acuity at 20 feet
                  or in relation to the 200 letter of the Snellen chart by multiplying or dividing the
                  numerator and the denominator by the same number. For example, a reported visual acuity
                  of 10/100 is essentially a visual acuity of 20/200 and a reported visual acuity of
                  20/ 800 is essentially a visual acuity of 5/200.
                Regular ophthalmic lenses do not include contact lenses or other special visual aids.
                  If best correction obtained by regular ophthalmic lenses does not result in remaining
                  visual efficiency (see F. below) of greater than 20% visual efficiency, the case may
                  be allowed in accordance with §382.06, unless an examining ophthalmologist recommends
                  the use of special lenses (e.g., contact or telescopic lenses), in which case consideration
                  should be given to the improvement in visions thereby attainable. The file should
                  contain specific evidence from the examining ophthalmologist as to the extent to which
                  the special lenses restore useful vision to the claimant.

            D.  
                Field of Vision --Disability due to loss of peripheral vision may result if there is severe contraction
                  of the visual field. The contraction may be either symmetrical or irregular. The extent
                  of the remaining visual field will be determined by usual perimetric methods, utilizing
                  a white target which subtends a 0.5-degree angle (3mm. white disc at a distance of
                  330 mm.) under illumination of not less than 7 foot-candles. The result should be
                  plotted on an ordinary visual field chart on each of the eight 45-degree principal
                  meridians. (Refer to Tables No. 3 and 5, §382.11, for definitions of terms and chart
                  of visual fields.)

                Muscle Function --Paralysis of the third cranial nerve producing ptosis, paralysis of accommodation,
                  an dilatation and immobility of the pupil may cause significant visual impairment.
                  When all the muscles of the eye are paralyzed, including the iris and ciliary body
                  (total ophthalmoplegia), the condition may be disabling, providing it is bilateral.
                  A finding of disability based primarily on impaired muscle function should be supported
                  by pathological findings, measurement of ocular mobility by standard perimetric and
                  tangent screen testing or muscle function chart.

                Visual Efficiency --Disability due to loss of visual efficiency may be caused by disease or injury
                  resulting in both a reduction of central visual acuity and visual field defects. The
                  visual efficiency of one eye is the product of the percentage of central visual efficiency
                  and the percentage of visual field efficiency. (See Tables No. 1, 3, and 4 § 382.11.)

            G.  
                Special Situations --Aphakia represents a visual handicap in addition to the loss of central visual
                  acuity. In cases of binocular aphakia, the central visual efficiency of the better
                  eye may be accepted as 75% of its value. In cases of monocular aphakia, where the
                  better eye is aphakic, the central visual efficiency may be acceptable as 50% of its
                  value. (Refer to Table No. 1, §382.11.)
                Glaucoma refers to a group of diseases characterized by abnormal elevation of intraocular
                  pressure and anatomic and functional changes resulting from abnormal pressure. Although
                  acute glaucomatous attacks may produce a rapid and severe loss of vision, prompt treatment
                  usually results in restoration of useful vision. The gradual loss of vision caused
                  by chronic glaucoma, however, is permanent. Invariably, peripheral visual field defects
                  occur before a reduction in central visual acuity.
                Ocular symptoms of systemic disease may or may not produce a disabling visual impairment.
                  These manifestations should be evaluated as part of the underlying disease entity
                  by reference to the particular body system involved.

            H.  
                Determination of Hearing Loss --While many deaf persons adjust well to social living and engage in substantial
                  gainful activity, others are incapacitated by less than total deafness. Since the
                  most important aspect of hearing is the ability to hear and understand speech correctly,
                  impairment in ability to hear sound alone may not reveal the full extent of functional
                  hearing loss, because speech consists of many components. Although there is usually
                  a close parallel between inability to understand speech, the two may diverge widely,
                  with a moderate loss of auditory acuity being complicated by serious difficulty in
                  speech discrimination.
                Accordingly, deafness should be evaluated in terms of the person's ability to hear
                  and distinguish speech. The degree of functional hearing loss is that loss of hearing
                  and discrimination for speech which is not restorable by a hearing aid. Loss of hearing
                  may be determined with an audiometer or by other appropriate auditory testing. Discrimination
                  for speech may be determined with a speech audiometer or a hearing aid and the use
                  of phonetically balanced word lists (e.g., the PB-50's prepared at Harvard University
                  or the W-22 recordings developed by the Central Institute for the Deaf). These special
                  tests lists consist of words selected so that the frequency of speech sounds in the
                  group is the same as the frequency of the same sounds in an average vocabulary of
                  conventional American English.

                Pulmonary Tuberculosis --Tuberculosis is a communicable disease and, as such, disability due to tuberculosis
                  is determined primarily on the basis of activity of the disease. Individuals who meet
                  the criteria described in the listing for pulmonary tuberculosis (§383.08) will be
                  found to have a disabling impairment which is expected to last for a period of at
                  least 12 months. Other medical factors, including proposed surgery, will not militate
                  against such a finding.
                 Documentation --Activity of tuberculosis (active, inactive, quiescent) and extent of pulmonary
                  lesion on roentgenogram are defined in the “Diagnostic Standards and Classification of Tuberculosis” (NTA, 1961, pp. 39-41). Tuberculosis will be considered to be present only where
                  typical bacilli, M. Tuberculosis, have been demonstrated by growth in culture or by
                  guinea pig inoculation. Where sputa (gastrics) have not been cultured or reported
                  monthly for six months, as required for definition of activity, a presumption will
                  be made that the intervening specimens were negative, if a current sputum is negative.
                  The initial report should contain all the culture findings available with dates of
                  collection of specimens. The date of the positivity or negativity of a specimen is
                  the date of its collection. If the date of collection of a specimen is not reported,
                  it will be assumed that the specimen was collected eight weeks prior to the date of
                  the report of culture. Suspected or questionable cavitary disease identified on the
                  basis of a conventional PA 14 ×17 inch film will be considered to be non-cavitary
                  unless confirmed by laminograms. Generally, individuals with “inactive” or “quiescent” disease are not prevented from engaging in substantial gainful activity. Impairment
                  of pulmonary function due to extensive pulmonary tuberculosis may be evaluated under
                  the guides for chronic obstructive airway disease.
                 Onset --The onset of the impairment due to tuberculosis will be the date the X-ray was
                  taken or the sputum (gastric) was collected on the basis of which a diagnosis of tuberculosis
                  was made; or the date of work cessation, if work ceased within 3 months preceding
                  diagnosis by X-ray or bacteriologic finding. If work cessation preceded diagnosis
                  by more than 3 months, onset of impairment due to tuberculosis will be considered
                  to be 3 months preceding the date of X-ray or the date the sputum was collected.

                When a Respiratory Impairment is Episodic in Nature, as may occur in complications of bronchiectasis and mycotic asthma infections of
                  the lung, the frequency of severe episodes is the criterion for determining level
                  of impairment.

            D.  
                Cor Pulmonale --Chronic cor pulmonale as used in § 383.12 refers to a condition in which the right
                  ventricle is enlarged as a consequence of a primary respiratory disease. Therefore,
                  the clinical diagnosis of the respiratory disorder must be established by history,
                  physical findings and chest X-ray. Right ventricular enlargement or outflow tract
                  prominence may be difficult to detect on routine PA film, particularly in the presence
                  of chronic obstructive airway disease. Consequently, lateral and oblique films or
                  chest fluoroscopy should be obtained, unless cardiac enlargement is established by
                  the PA film, as per §384.02.

            E.  
                Pulmonary insufficiency is a deleterious alteration in the normal physiologic function of the lungs and is
                  usually manifested clinically by a complaint of shortness of breath (dyspnea) and
                  by a decrease in exercise tolerance. Obstruction to the flow of air into and out of
                  the lungs or an inability of the lungs to oxygenate blood normally are examples of
                  abnormal function. The various physiologic defects that contribute to pulmonary insufficiency
                  can be measured objectively and accurately when appropriate tests are properly performed.
                  Therefore, these tests are used to assess the severity of impairment. There is no
                  one test that measures all types of physiolgic defects. The tests include in the listings
                  represent those that will best reflect the degree of pulmonary insufficiency present
                  in the disease categories in which they are included.
                
 
 
 Documentation of Pulmonary Insufficiency --Spirometric studies for evaluation under Tables I, II, III, IV, and VI must be
      reported in liters. The MVV (maximum voluntary ventilation), sometimes called the
      MBC (maximum breathing capacity), is defined as the maximum volume of air that can
      be breathed per minute. The MVV or the MBC reported should represent the observed
      value and should not be caluculated from FEV 1 . The FEV1 (one-second forced expiratory volume, one-second forced vital capacity) is defined
      as the maximal volume of air that can be forcibly exhaled during the first second
      starting from full inspiration. The VC (vital capacity) or FVC (forced vital capacity)
      is defined as the maximal volume of air that can be exhaled starting from full inspiration.
      Reported values should represent the largest of at least three attempts. Values must
      be expressed in liters or liters per minute. They should be accompanied, whenever
      possible, by appropriately labeled spirometric tracings and by a statement as to the
      applicant's cooperation and effort. Where effort is less than optimal, results should
      be interpreted with great caution. Studies should not be performed during or soon
      after an acute respiratory illness. If wheezing is present on auscultation of the
      chest, studies should be performed following administration of nebulized bronchodilator.

            F.  
                Obstructive Airway Disease --The three tables to be used for evaluation of cases involving chronic obstructive
                  airway disease are Tables I, II, and III in §383.02. They relate to an individual's
                  physical capacities to do light, medium, or heavy work as defined in the Dictionary
                  of Occupational Titles (Vol. 2, App. B, pages 654-655.
                
 
 
 Table I --If a claimant has an MVV and FEV1 equal to, or less than, those specified in Table I, he may be found to have an impairment
      of pulmonary function severe enough to preclude  any substantial gainful activity on medical considerations alone. Hence, consideration
      of  vocational factors is not necessary. 
   
    Table II --If a claimant's MVV or FEC1 are greater than specified in Table I but equal to, or less than, those specified
      in Table II, he has sufficiency breathing capacity to engage in  light, but not medium or heavy work activity. Therefore, consideration of vocational factors
      would be necessary to determine whether the individual has the vocational capabilities
      for  light work activity.
   
   
    Table III --If a claimant has an MVV and FEV1 greater than specified in Table II but equal to or less than specified in Table III,
      he has sufficient breathing capacity to do  light and  medium , but not heavy work activity. Consideration of vocational factors would be required
      to determine whether the individual has the vocational capabilities for  light or  medium work activity.
   
   
   The individual who has an MVV and FEV1  greater than shown in Table III has the breathing capacity for light, medium, and heavy work.
      Therefore, in the absence of an impairment other than chronic obstructive airway disease,
      vocational assessment will not ordinarily be needed since his respiratory capacity
      is sufficient to enable him to engage in  any substantial gainful activity.

384. Cardiovascular System 
   
   
      - 
         
            A.  
               There is no single clinical test which will measure accurately the functional capacity
                  of the heart. This is best determined by the ability of the individual to engage in
                  a given degree of activity without producting significant signs and symptoms. Symptoms
                  alone are not conclusive evidence of disability. Symptoms must be supported by objective
                  clinical findings such as cardiac enlargement, ECG changes, edema, etc.
                Regardless of the cause of heart disease, disability results from one of two principal
                  consequences of the disease. One is congestive heart failure and the other is ischemia
                  or death of heart muscle. The listings spell out a level of severity in terms of symptoms,
                  signs, and laboratory findings. It is recognized, however, that the listings do not
                  include all possible findings. The exercise of judgment is needed to determine whether
                  the impairment described in the medical record parallels the level of severity described
                  in the listing.
                
 
 
- 
         
            B.  
                Mild exertion is used in the listings to refer to such activities as walking several blocks at
                  a rate of 2-3 miles per hour, using public transportation, doing small chores, and
                  engaging in the ordinary activities of daily living. Some examples of the latter would
                  include driving an automobile and performing household tasks, such as washing dishes
                  and sweeping the floor, as well as the personal care activites of washing, dressing,
                  shaving, etc. Symptoms developing on such activities will be held to occur on mild
                  exertion.
                 Chest pain by itself and in the absence of corroborative evidence is insufficient to warrant
                  a finding of disability. The history should be meticulously recorded in the file and
                  should contain an approximate date of onset. The description of the chest discomfort
                  should include the quality of the discomfort (tight, constricting, oppresive, vise-like,
                  or burning), its intensity, location, and radiation. The regularity and promptness
                  of relief by rest and nitroglycerin should be specifically described. The relationship
                  of exertion should be carefully reported with a specific description of the amount
                  of exertion required to produce pain, expressed in terms of numbers of level blocks
                  walked or flights of stairs ascended at normal speed. Any relationship to eating and
                  emotional stress should be indicated. If there is any pain at rest or angina decubitus,
                  this shoud be described in great detail to permit differentiation from extracardiac
                  chest pain. Common conditions which may simulate angina pectoris include cervical
                  or dorsal arthritis or disc, chest wall syndrome, hyperventilation syndrome, esophageal
                  or gastroduodenal or gallbladder disorders. There should be some objective sign or
                  laboratory finding to validate the subjective complaint and corroboration by ECG evidence
                  is preferred. All ECG tracings preferably should be a part of the file.
                 Heart block must be evaluated in terms of impairment of function. This will usually take the
                  form of cardiac syncope which must be differentiated from syncope due to other causes
                  such as vasovagal attacks, hysterical episodes, and epilepsy. Cardiac syncope is most
                  frequently associated with sudden alterations in rate or rhythm such as heart block
                  of high degree or extreme paroxysmal tachycardia. In addition, persons with high grade
                  aortic stenosis may develop syncope or even epileptiform seizures on effort.
                
 
 
- 
         
            C.  
                Congestive heart failure is considered in the listings under one category regardless of the etiology producing
                  the heart failure (e.g., arteriosclerotic, hypertensive, rheumatic, pulmonary, congenital,
                  syphilitic heart disease). It is a clinical state due to decreased muscular effectiveness
                  of the heart characterized mainly by cardiac enlargement, shortness of breath, and/or
                  peripheral edema.
                
 
 
- 
         
            D.  
                Arteriosclerotic heart disease or coronary artery disease is by far the most common cause of myocardial ischemia.
                  This is due to a narrowing of the coronary arteries by the arteriosclerotic process.
                  It constitutes a clinical spectrum ranging from complete compensation and absence
                  of pain under heavy load to severe angina or decompensation at rest. The degree of
                  functional impairment may range from none to total, depending on the signs and symptoms
                  produced by activity.
                
 
 
- 
         
            E.  
                Hypertensive vascular disease produces disability when it causes complications in one or more of the four main
                  end organs--the heart, the brain, the kidneys, the eyes (retina). This may occur singly
                  or in combination and to varying degrees in the different end organs.

            F.  
                Diseases of the Arteries and Veins --The conditions considered in the listing related to the peripheral vessels of the
                  extremities. However, disease of the major branches are also considered. These diseases
                  are reflected in findings such as failure of visualization of segments of the arterial
                  system of an extremity on an arteriogram, neurological changes (ischemic neuritis),
                   or absent peripheral arterial pulis aline, ulceration, gangrene, persistent coldness,
                  and white or bluish discoloration of the extremities or parts thereof, and edema.

            G.  
                Collagen--vascular disorders --Periarteritis nodosa (polyarteritis, necrotizing angiitis), dermatomyostis (polymyositis),
                  systemic lupus erythematosus, an scleroderma (progressive systemic sclerosis) constitute
                  a group of clinical syndromes usually known as diseases of connective tissue or collagen--vascular
                  disesase. While these syndromes have certain pathological features in common with
                  widespread damage in the connective tissue, each presents a more or less distinct
                  clinical pattern. They are as a group characterized by constitutional manifestations
                  in addition to local lesions usually involving blood vessels, joints, heart, skin,
                  muscles, and the supporting tissues of the viscera. The clinical features are largely
                  determined by the distribution and rate of development of these lesions.

            H.  
                Surgical Procedures in Heart Disorders --The treatment of congenital or acquired heart disease by means of surgery, including
                  insertion of a pacemaker, is relatively new and experimental. The amount of function
                  restored and the time required to effect improvement in an individual treated by these
                  methods varies considerably with the nature of the disorder, the type of surgery involved
                  and many other individual factors. Therefore, in cases involving heart surgery, the
                  individual will be deemed to be under a disability for at least 12 months after the
                  operation. How long the individual may have been disabled prior to the operation will
                  be determined by all the evidence of record. Likewise, a finding as to the individual's
                  ability or inability to engage in substantial gainful activity 12 or more months after
                  the operation will require documentation and evaluation of all appropriate factors.

            A.  
               Diseases and disorders of the digestive system resulting in disability frequently
                  do so by reason of interference with the nutrition of the body as a whole. Such interference
                  may arise as a result of lowered food intake, incomplete digestion, or abnormal excretion
                  of intestinal contents. The severity of the concomitant malnutrition may be indicated
                  by loss of weight, loss of muscle tone, and anemia.

               A colostomy does not of itself ordinarily impose marked restriction of activity if
                  the individual is able to manage diet and irrigation. An ileostomy frequently requires
                  a bag due to the character of the discharge which is fluid. However, restriction of
                  ordinary activity is not always necessary with a properly fitted bag.

            A.  
               The most frequent disabling conditions under this system relate to disturbances of
                  kidney functions giving rise to symptoms and findings commonly associated with nephritis.
                  The glomerular type of nephritis, usually preceded by or associated with severe infectious
                  disease, is sudden in onset, and may clear up entirely or become chronic. The nephrosclerotic
                  type, related to hypertension  or arteriosclerosis, develops slowly with fewer laboratory findings and usually follows
                  a progressive course.

            B.  
               It may be necessary to permanently alter the normal course of outflow of urine when
                  disease or trauma destroys portions of the urinary tract. In these cases, evaluation
                  should take into consideration the underlying medical condition as well as the method
                  used in establishing urinary diversion. Significant complications that might result
                  after an ileal diversion are in the area of renal impairment such as progressive hydronephrosis
                  or pyelonephritis with constitutional symptoms.

      - 
         
            A.  
                Cause of Disability --Disability based upon anemia results from inadequate oxygenation of tissues caused
                  by a reduction of the oxygen carrying capacity of the blood. Hematologic defects can
                  also result in defective hemostatic mechanisms with hemorrhage into such functional
                  components as the brain or major joints, or thrombosis of the vascular supply of vital
                  organs. Formation of tumors may cause compression of vital structures or erosion of
                  bone. Deposits of breakdown products of the blood cells may cause impairment of hepatic
                  or renal function, joint deformity or formation of cholelithiasis with subsequent
                  bile duct obstruction.
                Where involvement of other organ systems has occurred as a result of hematologic disease,
                  these impairments shoud be evaluated according to the criteria listed under the appropriate
                  sections. The major complications of hematologic disorders are congestive heart failure
                  or angina associated with chronic anemia, or occlusion of coronary arteries (§384),
                  hepatic disease or biliary obstruction with jaundice (§385), renal disease ( §386),
                  and infiltrations or pathologic fractures of bones (§ 381). Occlusions of cerebral
                  vessals or hemorrhage into the central nervous system also represent a common complication
                  of hematologic disease. Since further damage to the central nervous system may be
                  expected to occur because of the primary hematologic disease, these individuals should
                  not be required to meet a level of severity as listed under the Nervous System (§391).
                  Where a permanent motor or sensory deficit or organic brain syndrome of any degree
                  exists which is caused by a persisting hematologic disease, the individual will be
                  found to have a disabling impairment which is expected to last for a period of at
                  least 12 months.
                Red blood cells may be replaced by blood transfusion, but in some diseases this elevation
                  of hematocrit is only transient. A contemplated splenectomy should not, in itself,
                  militate against a finding of disability expected to last at least twelve months.
                The level of laboratory findings cited in the listings, i.e., hematocrit, serum bilirubin,
                  reticulocyte and blood platelet count, should reflect the values reported on more
                  than one examination. A single laboratory finding will not suffice to meet the level
                  described.

388. Skin 
   
   Conditions of the skin, including disfiguring scars and repugnant skin disease, will
      not ordinarily be found in themselves to be totally disabling. Some skin conditions,
      such as the ulcerations and exzemas associated with severe varicose veins, or the
      disfiguring and repugnant skin lesions of leprosy, are significant as manifestations
      of the underlying disabling condition. Large areas of skin surface are sometimes destroyed
      by severe burns with consequent scarring and disfigurement. Eventually, factors of
      contractures and deformities play a significant role in determining functional capacities,
      and these, in turn, should be evaluated on the basis of the Listing of Impairments
      for the Musculoskeletal System (§381 ff.).

   388.04 Pemphigus --Consider under §388.03. 
   
    
   
   389. Endrocrine System 
   
   
      - 
         
            A.  
                Cause of Disability --Disability is caused by overproduction or underproduction of hormones resulting
                  in structural and/or functional changes in the body. Where involvement of other organ
                  systems has occurred as a result of a primary endocrine disorder, these impairments
                  should be evaluated according to the criteria listed under the appropriate sections.
                  The major complications of endocrine disorders are cardiovascular (§384), psychiatric
                  (§392), genitourinary (§386), hematologic ( §387), and musculoskeletal abnormalities
                  (§381). Hyperfunction or hypofunction of the adenohypophysis does not in itself cause
                  an impairment. The impairment results from subsequent malfunction of the affected
                  target gland, and the impairment should be evaluated according to the listings for
                  the appropriate target gland.

            B.  
                Diabetes Mellitus --Diabetes mellitus is a chronic disorder of metabolism, characterized by hyperglycemia,
                  glycosuria, polyuria, polyphagia, polydipsia, weakness and weight loss. In most situations,
                  inability to engage will not result, because replacement therapy will adequately control
                  these abnormalities. Degenerative vascular changes may lead to complications and severe
                  impairment. The most commonly occurring disabling sequelae appear in the eyes, heart,
                  peripheral vascular system of the lower extremities, nervous system, and kidneys.
                  For example: recurrent and extensive diabetic changes in the blood vessels of the
                  retina may result in significant interference with visual efficiency. Neurogenic pathology
                  with destruction of a major joint is permanent, irreversible, and nonremediable, with
                  resulting gait impairment. Ambulation may also be significantly impaired with widespread
                  peripheral vascular degeneration in lower extremities. There may be significant renal
                  changes. Myocardial infarction may occur somewhat earlier than otherwise in diabetes
                  mellitus and also has a somewhat less favorable prognosis in the diabetic individual.
                  The course of pulmonary tuberculosis may be altered by the coexistence of the diabetic
                  state.
                
 
 
Adequate medical examinations and accurate measurement of functions are required in
      order to determine which organs are involved and how these have affected the individual's
      activites. This basic principle applies whether diabetes exists alone or in combination
      with other physical and/or mental impairment(s). Evaluation, when the musculoskeletal
      system is concerned, should be based on the demonstrated remaining capacities of the
      musculoskeletal system, and vascular changes or neurological changes.

390 The Nervous System 
   
    Introduction 
   
   Disorders of the nervous system are either neurological or psychiatric, and in some
      instances a combination of both.
   
   
   Neurological disorders are covered under §391. They include partial or complete loss
      of motor ability, abnormal motion such as convulsions, twitching, and tremors, and
      disturbance of sensory functions such as pain, tingling, and loss of hearing and position
      sense.
   
   
   The psychiatric disorders are covered in §392. They include disorders of perception
      (e.g., hallucinations); disorders of thinking (e.g., delusions, obsessions, suicidal
      rumination); disorders of affect (e.g., depression, elation); disorders of memory
      (e.g., amnesia, confabulation); disorders of consciousness (e.g., confusion, dream
      and fague states, stupor); disorders of intellect; and disorders of psychophysiological
      function.
   
   
    
   
   391. Neurology 
   
   
      - 
         
            A.  
                Neurological disturbances have, for the most part, demonstrable lesions in the central nervous system. Evidence
                  required for determiation of disability may be different for various neurological
                  impairments.
                
 
 
- 
         
            B.  
                Epilepsy --Epilepsy may be idiopathic, with onset in childhood, adolescence, or young adulthood.
                  In other cases, particularly with onset in later life, it may be symptomatic, i.e.,
                  due to a known precipitating cause, such as head injuries, brain tumors, infectious
                  diseases, heavy metal poisoning (e.g., lead, arsenic), or following brain surgery.
                  If possible, epilepsy should be substantiated by an EEG and at least one objective,
                  detailed description of a typical seizure, preferably one observed and reported by
                  a physician. Testimony of reliable lay persons may be acceptable for description of
                  seizures and establishment of their frequency only if professional observation is
                  not available, The severity of the impairment should be determined according to the
                  frequency, duration, and sequelae of seizures. If the disease is of long duration,
                  residual changes in personality and intellect should also be ascertained and evaluated
                  in conjunction with the epileptic condition.

            C.  
               Cerebrovascular Accident --The residuals of a cerebrovascular accident after the acute phase (usually 4 months
                  after onset) should be evaluated on the basis of the severity of the impairment of
                  speech, mental (see §392.02), sensory, and motor function. Particularly where impairment
                  of motor function of the extremities is the predominant residual impairment, evaluation
                  should include the consideration of any additional losses of body function due to
                  the disease process. See DISM §322.5 and §384.03.

                  parkinsonian symptoms.--Consider on the basis of residuals, referring to impairment
                  of arm, leg, and speech, and severity of any other residuals, such as tremors, etc.
                
 
 
- 
         
            E.  
                Brain Tumor --Signs and symptoms are due to increased intracranial pressure and/or neurological
                  deficit at the site of the lesion. Benign tumors can frequently be completely removed
                  without causing significant residual impairment. Malignant tumors can often be only
                  incompletely excised or, if inoperable, may be treated by craniotomy for relief of
                  headache or other signs of intracranial pressure; restoration of the individual's
                  ability to function will then usually be temporary or partial, and the overall prognosis
                  is poor. Occasionally, signs of an organic brain syndrome may develop.

    Introduction --For the purpose of this program, psychiatric disorders will be considered in four
      group entities: organic brain syndromes, functional disorders, personality disorders,
      and mental deficiency.
   
   
    Discusion of Psychiatric Disorders 
   
   
      - 
         
            A.  
                Organic Brain Syndromes are disorders caused by, or associated with, impairment of brain tissue.
                 Acute brain syndromes are mentioned for explanatory purposes only since their duration is too short to
                  assume adjudicative significance under our program. They are temporary and reversible
                  conditions with favorable prognosis and no significant residuals. They are short-lived,
                  self-limited, and do not produce “inability to work.” Occasionally, an acute brain syndrome may progress into a chronic brain syndrome.
                 Chronic Brain Syndromes result from relatively permanent, more or less irreversible, diffuse impairment of
                  cerebral tissue function. They are usually permanent and may be progressive. They
                  may be accompanied by psychotic or neurotic reactions superimposed on the organic
                  brain pathology. The degree of mental impairment may range from mild to severe.
                The individual's personal appearance and behavior at the time of the examination,
                  his daily activities, interests, and habits generally reflect the severity of the
                  impairment and are, therefore, very important in the evaluation process.
                Chronic brain syndromes can be found in connection with and/or may result from: 
                  - 
                     
                        1.  
                           Intracranial infections (e.g., CNS syphilis, encephalitides). 
 
 
- 
                     
                        2.  
                           Repeated and/or prolonged exposure to alcohol, drug, or toxic agents (e.g., Korsakoff's
                              psychosis, lead, arsenic, carbon monoxide).
                            
 
 
- 
                     
                        3.  
                           Trauma producing diffuse and permanent brain damage. 
 
 
- 
                     
                        4.  
                           Circulatory disturbance (e.g., cerebral arteriosclerosis, embolism, thrombosis, intracranial
                              hemorrhage).
                            
 
 
- 
                     
                        5.  
                           Convulsive disorders (epilepsy) and intracranial neoplasms. 
 
 
- 
                     
                        6.  
                           Metabolic and degenerative disoreders (e.g., pellagra, multiple sclerosis, Alzheimer's
                              and Pick's disease, Huntington's chorea).
                            
 
 
 
 
 
- 
         
            B.  
                Functional Psychiatric Disorders are disorders of psychogenic origin, without demonstrable structural changes in the
                  brain tissue. Allowed cases involving functional mental impairments should be scheduled
                  for periodic reexaminations as required by §253.
                 Psychotic Disorders --Involutional psychotic, manic-depressive, psychotic depressive, schizophrenic and
                  paranoid reactions are characterized by varying degrees of personality disoranization
                  and accompanied by a corresponding degree of inability to maintain contact with reality
                  (e.g., hallucinations, delusions). The capacity for effective work and ability to
                  relate to other people may be temporarily or permanently impaired.
                 Nonpsychotic Disorders  
                  - 
                     
                        1.  
                           Psychophysiologic autonomic and visceral disorders (cardiovascular, gastrointestinal,
                              genitourinary, musculoskeletal, respiratory).--In these disorders, the normal physiological
                              expression of emotions is exaggerated by chronic emotional tensions, eventually leading
                              to a disruption of the autonomic regulatory system and to various visceral disorders.
                              If the condition persists, it may lead to demonstrable structural changes (e.g., peptic
                              ulcer, bronchial asthma, colitis, dermatitis).
                            
 
 
- 
                     
                        2.  
                           Psychoneurotic disorders (anxiety reaction, neurotic-depressive reaction, conversion
                              reaction, obsessive-compulsive reaction, phobias).--There are no gross falsifications
                              of reality such as observed in the psychoses in the form of hallucinations or delusions.
                              Psychoneuroses are based on deep-seated emotions and conflicts below the level of
                              conscious awareness which pose a profound threat to the psychological integrity of
                              the individual. The classification of psychoneurotc disorders is largely based on
                              the defense mechanism the individual employs to stave off the threat of emotional
                              decompensation (e.g., anxiety, depression, conversion, obsessive-compulsive or phobic
                              mechanisms.
                            Anxiety or depression occurring in connection with overwhelming external situations
                              (i.e., situational reactions) are not of a psychoneurotic nature. They are self-limited
                              and the symptoms generally recede when the situational stress diminishes.
                            
 
 
 
 
 
- 
         
            C.  
                Personality Disorders (Inadequate, schizoid, cyclothymic, paranoid personalities; emotional instability,
                  passive-aggressive and passive-dependent behavior; compulsive personality; antisocial
                  behavior, sexual deviation, addiction; lack of motivation).--These disorders, the
                  result of inherent defects in personality structure, are often characterized by lifelong
                  patterns of inadequate or socially unacceptable behavior with minimal subjective anxiety
                  and little or no sense of distress. In contrast with neuroses and psychoses in which
                  the individual succumbs to environmental stress, an individual with a personality
                  disorder will often make an attempt (not infrequently successful) to alter or influence
                  the environment to conform with his self-centered confort, without motivation for
                  improvement. In our present state of knowledge, the personality structure of these
                  individuals can rarely, if ever, be altered by any form of therapy; however, in some
                  cases, functioning may be improved by prolonged, specialized treatment.
                Personality disorders by themselves are not disabling. On the other hand, individuals
                  with a personality disorder would be found under a disability if there is:
                
                  - 
                     
                        1.  
                           Adequate evidence demonstrating that the patterns of inadequate or socially unacceptable
                              behavior are symptomatic of underlying organic brain syndrome (e.g., post-traumatic
                              or post-encephalitic personality disorders) or functional mental illness (e.g., schizophrenic
                              reaction). The determination of disability is based on the severity of the underlying
                              organic or functional mental illness.
                            
 
 
- 
                     
                        2.  
                           Adequate evidence of organic brain pathology or of medical or surgical pathology as
                              a direct result of socially unacceptable behavior (e.g., Korsorkoff's syndrome, other
                              encephalopathies, cirrhosis of the liver; injuries sustained during antisocial activity).
                              The determination of disability will be based primarily on the severity of the superimposed
                              pathology.
                            
 
 
- 
                     
                        3.  
                           Adequate evidence of a severe psychoneurosis or psychosis. Not included in this category
                              are brief psychotic episodes which occur not infrequently in prisoners in reaction
                              to the environment.

            D.  
                Mental Deficiency denotes a lifelong disorder characterized by below-average intellectual endowment
                  as measured on standard intelligence tests (IQ) and associated with impairment in
                  one or more of the following areas: learning, maturation, and social adjustment.
                The following paragraphs discuss evidence required in cases involving mental deficiency. 
                  - 
                     
                        1.  
                           The degree of impairment due to mental deficiency should be determined primarily on
                              the IQ and the medical report. Intelligence tests should be administered and interpreted
                              by a qualified psychologist or psychiatrist utilizing such examinations as the Wechsler
                              Adult Intelligence Scale (WAIS), the Wechsler Intelligence Scale for Children (WISC),
                              and the revised Stanford-Binet, or (when indicated) performance type tests such as
                              Pintner-Patterson or Grace Arthur, etc. In communities where a qualified psychologist
                              or psychiatrist is not readily available, an intelligence test administered by a VR
                              counselor or a specially trained person associated with the local school system may
                              be accepted, particularly when other findings are also demonstrative of extremely
                              low intellectual capacity. The test should be administered at age 16 or over. An IQ
                              taken at an earlier age may be accepted if the longitudinal evidence demonstrates
                              incapacity of such severity that additional testing would serve no useful purpose.
                            
 
 
- 
                     
                        2.  
                           In cases where the nature of the individual's impairment is such that testing, as
                              described above, is precluded or cannot be obtained, the medical reports should give
                              specific information describing the level of intellectual, social and physical function
                              to support the indication that the individual is incapacitated. Actual observations
                              by district office or State agency personnel, reports from educational institutions,
                              information furnished by public welfare agencies, or other reliable objective sources
                              should be considered as lending additional weight to the evidence in the medical report.

                        3.  
                           In some cases mental deficiency is only part of the impairment. The applicant may
                              also have cerebral palsy, epilepsy, psychosis, etc. If the associated condition is
                              such as to constitute a “disability,” it is unnecessary to secure the IQ.

                Prognosis in Psychiatric Disorders (See §253 for establishing medical reexamination dates).--
                
                  - 
                     
                        1.  
                           The impairment of brain tissue in the chronic organic brain syndromes and mental deficiency
                              generally being irreversible, recovery or remission in these conditions is not the
                              rule.
                            
 
 
- 
                     
                        2.  
                           Mood disorders (manic-depressive reaction, involutional psychotic reaction, psychotic
                              depressive reaction) generally respond well to psychiatric treatment, although relapses
                              may occur.
                            
 
 
- 
                     
                        3.  
                           The prognosis in schizophrenic reactions is generally guarded and depends on factors
                              such as the duration of the illness (acute versus chronic) and the type of reaction
                              (simple, catatonic, hebephrenic, paranoid, etc).
                            
 
 
- 
                     
                        4.  
                           The prognosis is psychoneurosis and psychophysiologic disorders is generally favorable
                              with proper psychiatric treatment.
                            
 
 
- 
                     
                        5.  
                           In personality disorders which are characterized by a lifelong pattern of inadequate
                              or socially unacceptable behavior, motivation for treatment is frequently lacking
                              and changes in the personality structure are not likely to occur. However, functioning
                              may be improved by prolonged, specialized treatment.

            F.  
                Documentation --The severity of a psychiatric disorder can be evaluated on the basis of:
                
                  - 
                     
                        1.  
                           Physician's report (preferably by a psychiatrist) which include history, objective
                              findings, diagnosis, response to therapy.
                            
 
 
- 
                     
                        2.  
                           Daily Activities--Since severity of impairment is generally in direct proportion to
                              its effect on the individual's daily activities, interests, personal habits, behavior,
                              and the ability to relate to others, such information is very valuable in the adjudicative
                              process. Much of this information is obtainable from a psychiatric social service
                              survey. However, this information may also be obtained from the applicant (R/C), his
                              former employer, physician, clinical psychologist, hospital and court records, social
                              service and welfare agencies.

                        3.  
                           Psychological Tests--In some cases, psychological tests (for intelligence level, organicity,
                              personality make-up, etc.) may be helpful in differential diagnosis.

                        4.  
                           Hospital Reports--When the claimant is hospitalized for “mental illness,” it is necessary to obtain a Form OA-D824 or a summary psychiatric report adequately
                              showing history, physical and mental status examination, and other clinical data including
                              diagnosis, therapy, response to treatment, prognosis, and social, industrial and occupational
                              activities while in the hospital.
                            It is ordinarily necessary to obtain the record of his course in the hospital and
                              a current medical report from the individual's attending physician, the hospital staff,
                              or other sources. Hospital reports should definitely indicate whether or not the hospitalization
                              has been continuous and, in cases where there is doubt as to the continuity of the
                              hospitalization, development of this point should be undertaken. Experience has demonstrated
                              that many reports fail to mention extended period of trial visit which may have a
                              bearing on the adjudication of the case.
                             Release of trial visit is often an indication of improvement. However, some patients are released because
                              they are not particularly dangerous to themselves or others, have reached a point
                              where they are not longer able to benefit from hospital treatment, and instead require
                              supervision (custodial care). Some leave the hospital because they are senile and
                              harmless; others, as a result of insistence by the family. Trial visit then, in and
                              of itself, does not necessarily indicate recovery or that recovery is foreseeable,
                              and requires further development to determine its basis.
                             Recurrent hospitalizations are often evidence of a severe impairment. In determining whether a claimant was
                              under a disability, consideration should be given to the length of time lapse between
                              each period of hospitalization, the reasons for hospitalization, the severity of the
                              impairment and response to treatment particularly as reflected in the claimant's adjustment
                              out of the hospital.
                            An individual may be receiving institutional care because of the commission of a crime
                              rather than for the impairment or he may be hospitalized because of a personality
                              disorder which may or may not be a manifestation of an underlying functional or orgainic
                              psychiatric illness. In such cases, the determination of disability is based on the
                              severity of the mental disorder and the resulting impairment as evidenced by the clinical
                              findings regardless of the reason for the commitment.

393. Neopastic Disease--Malignant 
   
   
      - 
         
            A.  
                Definition --A malignant neoplastic disease is one in which cells become autonomous. Their rate
                  of growth and reproduction increases. They may spread from their original location
                  to adjacent and distant organs in the same and other body cavities. They usually alter
                  the normal physiological mechanisms to such an extent that severe disability may follow.
                
 
 
- 
         
            B.  
               Establishing the Diagnosis --The diagnosis is needed to help determine (1) whether the specific disease for
                  which applicant claims disability is actually present, (2) whether it will meet the
                  12-month duration requirement or end in death; (3) whether it produced disability
                  so severe as to prevent the applicant from engaging in substantial gainful activity.
                The diagnosis should be established by adequate evidence which in most instances would
                  include histopathological study of a biopsy. The biopsy helps define cell type, organs
                  involved, possibility of metastasis, and possibility of producing disability effects.
                  Gross pathological evidence should be used only under unusual circumstances; these
                  circumstances limited largely to unavailability of diagnostic facilities, in which
                  case the clinical evidence should be such that a reviewing physician, given only findings,
                  could arrive at an independent diagnosis.
                
 
 
- 
         
            C.  
                Evaluation of Impairment --The disabling effects of malignant neoplastic disease are varied. The end result
                  is inability to cerebrate, oxygenate, locomote, manipulate, etc. There are a few malignant
                  diseases in which “disability” is nearly always present or shortly will be by virtue of their location in vital
                  organs, e.g., liver, brain, heart.
                Studies on employment of cancer patients following surgery and/or irradiation have
                  shown that many patients are physically able to resume their usual occupations or
                  activites. Physical changes in body form and function do not unduly interfere with
                  resumption of work or other activities after a short period of convalescence where
                  the disease is confined to the primary site (with certain exceptions noted above)
                  or involves local lymph nodes which are completely resected at the time of surgery.
                The presence of distant metastasis may be considered severe enough to prevent substantial
                  gainful activity in that severe impairment is present or may be expected to soon follow.
                  Evidence of metastasis may be established by biopsy or appropriate clinical precedures
                  where the primary lesion has been confirmed by biopsy.
