   112.00 MENTAL DISORDERS
   
   A. Introduction
   
   The structure of the mental disorders listings for children under age 18 parallels
      the structure for the mental disorders listings for adults but is modified to reflect
      the presentation of mental disorders in children. The listings for mental disorders
      in children are arranged in 11 diagnostic categories: Organic mental disorders (112.02);
      schizophrenic, delusional (paranoid), schizoaffective, and other psychotic disorders
      (112.03); mood disorders (112.04); mental retardation (112.05); anxiety disorders
      (112.06); somatoform, eating, and tic disorders (112.07); personality disorders (112.08);
      psychoactive substance dependence disorders (112.09); autistic disorder and other
      pervasive developmental disorders (112.10); attention deficit hyperactivity disorder
      (112.11); and developmental and emotional disorders of newborn and younger infants
      (112.12).
   
   
   There are significant differences between the listings for adults and the listings
      for children. There are disorders found in children that have no real analogy in
      adults; hence, the differences in the diagnostic categories for children. The presentation
      of mental disorders in children, particularly the very young child, may be subtle
      and of a character different from the signs and symptoms found in adults. For example,
      findings such as separation anxiety, failure to mold or bond with the parents, or
      withdrawal may serve as findings comparable to findings that mark mental disorders
      in adults. The activities appropriate to children, such as learning, growing, playing,
      maturing, and school adjustment, are also different from the activities appropriate
      to the adult and vary widely in the different childhood stages.
   
   
   Each listing begins with an introductory statement that describes the disorder or
      disorders addressed by the listing. This is followed (except in listings 112.05 and
      112.12) by paragraph A criteria and paragraph B criteria (a set of impairment-related
      functional limitations). An individual will be found to have a listed impairment
      when the criteria of both paragraphs A and B of the listed impairment are satisfied.
   
   
   The purpose of the criteria in paragraph A is to substantiate medically the presence
      of a particular mental disorder. Specific symptoms and signs under any of the listings
      112.02 through 112.12 cannot be considered in isolation from the description of the
      mental disorder contained at the beginning of each listing category. Impairments
      should be analyzed or reviewed under the mental category(ies) indicated by the medical
      findings.
   
   
   Paragraph A of the listings is a composite of medical findings which are used to substantiate
      the existence of a disorder and may or may not be appropriate for children at specific
      developmental stages. However, a range of medical findings is included in the listings
      so that no age group is excluded. For example, in listing 112.02A7, emotional lability
      and crying would be inappropriate criteria to apply to older infants and toddlers,
      age 1 to attainment of age 3; whereas in 112.02A1, developmental arrest, delay, or
      regression are appropriate criteria for older infants and toddlers. Whenever the adjudicator
      decides that the requirements of paragraph A of a particular mental listing are satisfied,
      then that listing should be applied regardless of the age of the child to be evaluated.
   
   
   The purpose of the paragraph B criteria is to describe impairment-related functional
      limitations which are applicable to children. Standardized tests of social or cognitive
      function and adaptive behavior are frequently available and appropriate for the evaluation
      of children and, thus, such tests are included in the paragraph B functional parameters.
      The functional restrictions in paragraph B must be the result of the mental disorder
      which is manifested by the medical findings in paragraph A.
   
   
   We have not include separate C criteria for listings 112.02, 112.03, 112.04, and 112.06,
      as are found in the adult listings, because for the most part we do not believe that
      the residual disease processes described by these listings are commonly found in children.
      However, in unusual cases where these disorders are found in children and are comparable
      to the severity and duration found in adults, we may use the adult listings 12.02C,
      12.03C, 12.04C, and 12.06C criteria to evaluate such cases.
   
   
   The structure of the listings for Mental Retardation (112.05) and Developmental and
      Emotional Disorders of Newborn and Younger Infants (112.12) is different from that
      of the other mental disorders. Listing 112.05 (Mental Retardation) contains six sets
      of criteria. If an impairment satisfies the diagnostic description in the introductory
      paragraph and any one of the six sets of criteria, we will find that the child’s impairment
      meets the listing. For listings 112.05D and 112.05F, we will assess the degree of
      functional limitation the additional impairment(s) imposes to determine if it causes
      more than minimal functional limitations, i.e., is a “severe” impairment(s), as defined in § 416.924(c). If the additional impairment(s)
      does not cause limitations that are “severe” as defined in § 416.924(c), we will not
      find that the additional impairment(s) imposes an additional and significant limitation
      of function. Listing 112.12 (Developmental and Emotional Disorders of Newborn and
      Younger Infants) contains five criteria, any one of which, if satisfied, will result
      in a finding that the infant's impairment meets the listing.
   
   
   It must be remembered that these listings are only examples of common mental disorders
      that are severe enough to find a child disabled. When a child has a medically determinable
      impairment that is not listed, an impairment that does not meet the requirements of
      a listing, or a combination of impairments no one of which meets the requirements
      of a listing, we will make a determination whether the child’s impairment(s) is medically
      or functionally equivalent in severity to the criteria of a listing. (See §§ 404.1526,
      416.926, and 416.926a.)
   
   
   B. Need for Medical Evidence
   
   The existence of a medically determinable impairment of the required duration must
      be established by medical evidence consisting of symptoms, signs, and laboratory findings
      (including psychological or developmental test findings). Symptoms and signs generally
      cluster together to constitute recognizable mental disorders described in paragraph
      A of the listings. Psychiatric signs are medically demonstrable phenomena that indicate
      specific psychological abnormalities, e.g., abnormalities of behavior, mood, thought, memory, orientation, development, or perception,
      as described by an appropriate medical source. These findings may be intermittent
      or continuous depending on the nature of the disorder.
   
   
   C. Assessment of Severity
   
   In childhood cases, as with adults, severity is measured according to the functional
      limitations imposed by the medically determinable mental impairment. However, the
      range of functions used to assess impairment severity for children varies at different
      stages of maturation. The functional areas that we consider are: Motor function; cognitive/communicative
      function; social function; personal function; and concentration, persistence, or pace.
      In most functional areas, there are two alternative methods of documenting the required
      level of severity; 1) use of standardized tests alone, where appropriate test instruments
      are available, and 2) use of other medical findings. (See 112.00D for an explanation
      of these documentation requirements.) The use of standardized tests is the preferred
      method of documentation if such tests are available.
   
   
   Newborn and younger infants (birth to attainment of age 1) have not developed sufficient
      personality differentiation to permit formulation of appropriate diagnoses. We have,
      therefore, assigned listing 112.12 for Developmental and Emotional Disorders of Newborn
      and Younger Infants for the evaluation of mental disorders of such children. Severity
      of these disorders is based on measures of development in motor, cognitive/communicative,
      and social functions. When older infants and toddlers (age 1 to attainment of age
      3) do not clearly satisfy the paragraph A criteria of any listing because of insufficient
      developmental differentiation, they must be evaluated under the rules for equivalency.
      The principles for assessing the severity of impairment in such children, described
      in the following paragraphs, must be employed.
   
   
   Generally, when we assess the degree of developmental delay imposed by a mental impairment,
      we will use an infant's or toddler's chronological age; i.e., the child's age based on birth date. If the infant or toddler was born prematurely,
      however, we will follow the rules in § 416.924a(b) to determine whether we should
      use the infant's or toddler's corrected chronological age; i.e., the chronological age adjusted by the period of gestational prematurity.
   
   
   In defining the severity of functional limitations, two different sets of paragraph
      B criteria corresponding to two separate age groupings have been established, in
      addition to listing 112.12, which is for children who have not attained age 1. These
      age groups are: older infants and toddlers (age 1 to attainment of age 3) and children
      (age 3 to attainment of age 18). However, the discussion below in 112.00C1, 2, 3,
      and 4, on the age-appropriate areas of function, is broken down into four age groupings:
      older infants and toddlers (age 1 to attainment of age 3), preschool children (age
      3 to attainment of age 6), primary school children (age 6 to attainment of age 12),
      and adolescents (age 12 to attainment of age 18). This was done to provide specific
      guidance on the age group variances in disease manifestations and methods of evaluation.
   
   
   Where “marked” is used as a standard for measuring the degree of limitation it means
      more than moderate but less than extreme. A marked limitation may arise when several
      activities or functions are impaired, or even when only one is impaired, as long as
      the degree of limitation is such as to interfere seriously with the ability to function
      (based upon age-appropriate expectations) independently, appropriately, effectively,
      and on a sustained basis. When standardized tests are used as the measure of functional
      parameters, a valid score that is two standard deviations below the norm for the
      test will be considered a marked restriction.

            1.  
               Older infants and toddlers (age 1 to attainment of age 3).In this age group, impairment severity is assessed in three areas: (a) Motor development,
                  (b) cognitive/ communicative function, and (c) social function.
                a. Motor development. Much of what we can discern about mental function in these children frequently comes
                  from observation of the degree of development of fine and gross motor function. Developmental
                  delay, as measured by a good developmental milestone history confirmed by medical
                  examination, is critical. This information will ordinarily be available in the existing
                  medical evidence from the claimant's treating sources and other medical sources, supplemented
                  by information from nonmedical sources, such as parents, who have observed the child
                  and can provide pertinent historical information. It may also be available from standardized
                  testing. If the delay is such that the older infant or toddler has not achieved motor
                  development generally acquired by children no more than one-half the child’s chronological
                  age, the criteria are satisfied.
                b. Cognitive/communicative function. Cognitive/communicative function is measured using one of several standardized infant
                  scales. Appropriate tests for the measure of such function are discussed in 112.00D.
                  Screening instruments may be useful in uncovering potentially serious impairments,
                  but often must be supplemented by other data. However, in some cases, the results
                  of screening tests may show such obvious abnormalities that further testing will clearly
                  be unnecessary. For older infants and toddlers, alternative criteria covering disruption
                  in communication as measured by their capacity to use simple verbal and nonverbal
                  structures to communicate basic needs are provided.
                c. Social function. Social function in older infants and toddlers is measured in terms of the development
                  of relatedness to people (e.g., bonding and stranger anxiety) and attachment to animate or inanimate objects. Criteria
                  are provided that use standard social maturity scales or alternative criteria that
                  describe marked impairment in socialization.

            2.  
               Preschool children (age 3 to attainment of age 6). For the age groups including preschool children through adolescence, the functional
                  areas used to measure severity are: (a) Cognitive/communicative function, (b) social
                  function, (c) personal function, and (d) deficiencies of concentration, persistence,
                  or pace resulting in frequent failure to complete tasks in a timely manner. After
                  36 months, motor function is no longer felt to be a primary determinant of mental
                  function, although, of course, any motor abnormalities should be documented and evaluated.
                a. Cognitive/communicative function. In the preschool years and beyond, cognitive function can be measured by standardized
                  tests of intelligence, although the appropriate instrument may vary with age. A primary
                  criterion for limited cognitive function is a valid verbal, performance, or full scale
                  IQ of 70 or less. The listings also provide alternative criteria, consisting of tests
                  of language development or bizarre speech patterns.
                b. Social function. Social functioning refers to a child’s capacity to form and maintain relationships
                  with parents, other adults, and peers. Social functioning includes the ability to
                  get along with others (e.g., family members, neighborhood friends, classmates, teachers). Impaired social functioning
                  may be caused by inappropriate externalized actions (e.g., running away, physical aggression -- but not self-injurious actions, which are evaluated
                  in the personal area of functioning), or inappropriate internalized actions (e.g., social isolation, avoidance of interpersonal activities, mutism). Its severity must
                  be documented in terms of intensity, frequency, and duration, and shown to be beyond
                  what might be reasonably expected for age. Strength in social functioning may be documented
                  by such things as the child’s ability to respond to and initiate social interaction
                  with others, to sustain relationships, and to participate in group activities. Cooperative
                  behaviors, consideration for others, awareness of others' feelings, and social maturity,
                  appropriate to a child’s age, also need to be considered. Social functioning in play
                  and school may involve interactions with adults, including responding appropriately
                  to persons in authority (e.g., teachers, coaches) or cooperative behaviors involving other children. Social functioning
                  is observed not only at home but also in preschool programs.
                c. Personal function. Personal functioning in preschool children pertains to self-care; i.e., personal needs, health, and safety (feeding, dressing, toileting, bathing; maintaining
                  personal hygiene, proper nutrition, sleep, health habits; adhering to medication
                  or therapy regimens; following safety precautions). Development of self-care skills
                  is measured in terms of the child’s increasing ability to help himself/herself and
                  to cooperate with others in taking care of these needs. Impaired ability in this area
                  is manifested by failure to develop such skills, failure to use them, or self-injurious
                  actions. This function may be documented by a standardized test of adaptive behavior
                  or by a careful description of the full range of self-care activities. These activities
                  are often observed not only at home but also in preschool programs.
                d. Concentration, persistence, and pace. This function may be measured through observations of the child in the course of
                  standardized testing and in the course of play.

            3.  
               Primary school children (age 6 to attainment of age 12). The measures of function here are similar to those for preschool-age children except
                  that the test instruments may change and the capacity to function in the school setting
                  is supplemental information. Standardized measures of academic achievement, e.g., Wide Range Achievement Test-Revised, Peabody Individual Achievement Test, etc., may
                  be helpful in assessing cognitive impairment. Problems in social functioning, especially
                  in the area of peer relationships, are often observed firsthand by teachers and school
                  nurses. As described in 112.00D, Documentation, school records are an excellent source of information concerning function and standardized
                  testing and should always be sought for school-age children.
                As it applies to primary school children, the intent of the functional criterion described
                  in paragraph B2d, i.e., deficiencies of concentration, persistence, or pace resulting in failure to complete
                  tasks in a timely manner, is to identify the child who cannot adequately function
                  in primary school because of a mental impairment. Although grades and the need for
                  special education placement are relevant factors which must be considered in reaching
                  a decision under paragraph B2d, they are not conclusive. There is too much variability
                  from school district to school district in the expected level of grading and in the
                  criteria for special education placement to justify reliance solely on these factors.
                
 
 
- 
         
            4.  
               Adolescents (age 12 to attainment of age 18). Functional criteria parallel to those for primary school children (cognitive/communicative;
                  social; personal; and concentration, persistence, or pace) are the measures of severity
                  for this age group. Testing instruments appropriate to adolescents should be used
                  where indicated. Comparable findings of disruption of social function must consider
                  the capacity to form appropriate, stable, and lasting relationships. If information
                  is available about cooperative working relationships in school or at part-time or
                  full-time work, or about the ability to work as a member of a group, it should be
                  considered when assessing the child’s social functioning. Markedly impoverished social
                  contact, isolation, withdrawal, and inappropriate or bizarre behavior under the stress
                  of socializing with others also constitute comparable findings. (Note that self-injurious
                  actions are evaluated in the personal area of functioning.)
                a. Personal functioning in adolescents pertains to self-care. It is measured in the
                  same terms as for younger children, the focus, however, being on the adolescent's
                  ability to take care of his or her own personal needs, health, and safety without
                  assistance. Impaired ability in this area is manifested by failure to take care of
                  these needs or by self-injurious actions. This function may be documented by a standardized
                  test of adaptive behavior or by careful descriptions of the full range of self-care
                  activities.
                b. In adolescents, the intent of the functional criterion described in paragraph B2d
                  is the same as in primary school children. However, other evidence of this functional
                  impairment may also be available, such as from evidence of the child’s performance
                  in work or work-like settings.
                
 
 
D. Documentation
   
   1. The presence of a mental disorder in a child must be documented on the basis of
      reports from acceptable sources of medical evidence. See §§ 404.1513 and 416.913.
      Descriptions of functional limitations may be available from these sources, either
      in the form of standardized test results or in other medical findings supplied by
      the sources, either in the form of standardized test results or in other medical findings
      supplied by the sources, or both. (Medical findings consist of symptoms, signs, and
      laboratory findings.) Whenever possible, a medical source’s findings should reflect
      the medical source’s consideration of information from parents or other concerned
      individuals who are aware of the child’s activities of daily living, social functioning,
      and ability to adapt to different settings and expectations, as well as the medical
      source’s findings and observations on examination, consistent with standard clinical
      practice. As necessary, information from nonmedical sources, such as parents, should
      also be used to supplement the record of the child’s functioning to establish the
      consistency of the medical evidence and longitudinality of impairment severity.
   
   
   2. For some newborn and younger infants, it may be very difficult to document the
      presence or severity of a mental disorder. Therefore, with the exception of some
      genetic diseases and catastrophic congenital anomalies, it may be necessary to defer
      making a disability decision until the child attains 3 months of age in order to obtain
      adequate observation of behavior or affect. See, also, 110.00 of this part. This
      period could be extended in cases of premature infants depending on the degree of
      prematurity and the adequacy of documentation of their developmental and emotional
      status.
   
   
   3. For infants and toddlers, programs of early intervention involving occupational,
      physical, and speech therapists, nurses, social workers, and special educators, are
      a rich source of data. They can provide the developmental milestone evaluations and
      records on the fine and gross motor functioning of these children. This information
      is valuable and can complement the medical examination by a physician or psychologist.
      A report of an interdisciplinary team that contains the evaluation and signature
      of an acceptable medical source is considered acceptable medical evidence rather than
      supplemental data.
   
   
   4. In children with mental disorders, particularly those requiring special placement,
      school records are a rich source of data, and the required reevaluations at specified
      time periods can provide the longitudinal data needed to trace impairment progression
      over time.
   
   
   5. In some cases where the treating sources lack expertise in dealing with mental
      disorders of children, it may be necessary to obtain evidence from a psychiatrist,
      psychologist, or pediatrician with experience and skill in the diagnosis and treatment
      of mental disorders as they appear in children. In these cases, however, every reasonable
      effort must be made to obtain the records of the treating sources, since these records
      will help establish a longitudinal picture that cannot be established through a single
      purchased examination.
   
   
   6. Reference to a “standardized psychological test” indicates the use of a psychological
      test measure that has appropriate validity, reliability, and norms, and is individually
      administered by a qualified specialist. By “qualified,” we mean the specialist must
      be currently licensed or certified in the State to administer, score, and interpret
      psychological tests and have the training and experience to perform the test.
   
   
   7. Psychological tests are best considered as standardized sets of tasks or questions
      designed to elicit a range of responses. Psychological testing can also provide other
      useful data, such as the specialist’s observations regarding the child’s ability to
      sustain attention and concentration, relate appropriately to the specialist, and perform
      tasks independently (without prompts or reminders). Therefore, a report of test results
      should include both the objective data and any clinical observations.
   
   
   8. The salient characteristics of a good test are: (1) Validity, i.e., the test measures what it is supposed to measure; 2) reliability, i.e., the consistency of results obtained over time with the same test and the same individual;
      3) appropriate normative data, i.e., individual test scores must be comparable to test data from other individuals or
      groups of a similar nature, representative of that population; and 4) wide scope of
      measurement, i.e., the test should measure a broad range of facets/aspects of the domain being assessed.
      In considering the validity of a test result, we should note and resolve any discrepancies
      between formal test results and the child’s customary behavior and daily activities.
   
   
   9. Identical IQ scores obtained from different tests do not always reflect a similar
      degree of intellectual functioning. The IQ scores in listing 112.05 reflect values
      from tests of general intelligence that have a mean of 100 and a standard deviation
      of 15, e.g., the Wechsler series. IQs obtained from standardized tests that deviate significantly
      from a mean of 100 and standard deviation of 15 require conversion to a percentile
      rank so that the actual degree of limitation reflected by the IQ scores can be determined.
      In cases where more than one IQ is customarily derived from the test administered,
      e.g., where verbal, performance, and full scale IQs are provided in the Wechsler series,
      the lowest of these is used in conjunction with listing 112.05.
   
   
   10. IQ test results must also be sufficiently current for accurate assessment under
      112.05. Generally, the results of IQ tests tend to stabilize by the age of 16. Therefore,
      IQ test results obtained at age 16 or older should be viewed as a valid indication
      of the child’s current status, provided they are compatible with the child’s current
      behavior. IQ test results obtained between ages 7 and 16 should be considered current
      for 4 years when the tested IQ is less than 40, and for 2 years when the IQ is 40
      or above. IQ test results obtained before age 7 are current for 2 years if the tested
      IQ is less than 40 and 1 year if at 40 or above.
   
   
   11. Standardized intelligence test results are essential to the adjudication of all
      cases of mental retardation that are not covered under the provisions of listings
      112.05A, 112.05B, and 112.05F. Listings 112.05A, 112.05B, and 112.05F may be the bases
      for adjudicating cases where the results of standardized intelligence tests are unavailable,
      e.g., where the child’s young age or condition precludes formal standardized testing.
   
   
   12. In conjunction with clinical examinations, sources may report the results of screening
      tests, i.e., tests used for gross determination of level of functioning. Screening instruments
      may be useful in uncovering potentially serious impairments, but often must be supplemented
      by other data. However, in some cases the results of screening tests may show such
      obvious abnormalities that further testing will clearly be unnecessary.
   
   
   13. Where reference is made to developmental milestones, this is defined as the attainment
      of particular mental or motor skills at an age-appropriate level, i.e., the skills achieved by an infant or toddler sequentially and within a given time
      period in the motor and manipulative areas, in general understanding and social behavior,
      in self-feeding, dressing, and toilet training, and in language. This is sometimes
      expressed as a developmental quotient (DQ), the relation between developmental age
      and chronological age as determined by specific standardized measurements and observations.
      Such tests include, but are not limited to, the Cattell Infant Intelligence Scale,
      the Bayley Scales of Infant Development, and the Revised Stanford-Binet. Formal tests
      of the attainment of developmental milestones are generally used in the clinical setting
      for determination of the developmental status of infants and toddlers.
   
   
   14. Formal psychological tests of cognitive functioning are generally in use for preschool
      children, for primary school children, and for adolescents except for those instances
      noted below.
   
   
   15. Generally, it is preferable to use IQ measures that are wide in scope and include
      items that test both verbal and performance abilities. However, in special circumstances,
      such as the assessment of children with sensory, motor, or communication abnormalities,
      or those whose culture and background are not principally English-speaking, measures
      such as the Test of Nonverbal Intelligence, Third Edition (TONI-3), Leiter International
      Performance Scale-Revised (Leiter-R), or Peabody Picture Vocabulary Test-Third Edition
      (PPVT-III) may be used.
   
   
   16. We may consider exceptions to formal standardized psychological testing when an
      individual qualified by training and experience to perform such an evaluation is not
      available, or in cases where appropriate standardized measures for the child's social,
      linguistic, and cultural background are not available. In these cases, the best indicator
      of severity is often the level of adaptive functioning and how the child performs
      activities of daily living and social functioning.
   
   
   17. Comprehensive neuropsychological examinations may be used to establish the existence
      and extent of compromise of brain function, particularly in cases involving organic
      mental disorders. Normally, these examinations include assessment of cerebral dominance,
      basic sensation and perception, motor speed and coordination, attention and concentration,
      visual-motor function, memory across verbal and visual modalities, receptive and expressive
      speech, higher-order linguistic operations, problem-solving, abstraction ability,
      and general intelligence. In addition, there should be a clinical interview geared
      toward evaluating pathological features known to occur frequently in neurological
      disease and trauma, e.g., emotional lability, abnormality of mood, impaired impulse control, passivity and
      apathy, or inappropriate social behavior. The specialist performing the examination
      may administer one of the commercially available comprehensive neuropsychological
      batteries, such as the Luria-Nebraska or Halstead-Reitan, or a battery of tests selected
      as relevant to the suspected brain dysfunction. The specialist performing the examination
      must be properly trained in this area of neuroscience.
   
   
   Neuropsychological testing refers to the administration of standardized tests that are reliable and valid with
      respect to assessing impairment in brain functioning. It is intended that the psychologist
      or psychiatrist using these tests will be able to evaluate the following functions:
      Attention/concentration, problem-solving, language, memory, motor, visual-motor and
      visual-perceptual, laterality, and general intelligence (if not previously obtained).
   
   
   E. Effect of Hospitalization or Residential Placement
   
   As with adults, children with mental disorders may be placed in a variety of structured
      settings outside the home as part of their treatment. Such settings include, but are
      not limited to, psychiatric hospitals, developmental disabilities facilities, residential
      treatment centers and schools, community-based group homes, and workshop facilities.
      The reduced mental demands of such structured settings may attenuate overt symptomatology
      and superficially make the child’s level of adaptive functioning appear better than
      it is. Therefore, the capacity of the child to function outside highly structured
      settings must be considered in evaluating impairment severity. This is done by determining
      the degree to which the child can function (based upon age-appropriate expectations)
      independently, appropriately, effectively, and on a sustained basis outside the highly
      structured setting. On the other hand, there may be a variety of causes for placement
      of a child in a structured setting which may or may not be directly related to impairment
      severity and functional ability. Placement in a structured setting in and of itself
      does not equate with a finding of disability. The severity of the impairment must
      be compared with the requirements of the appropriate listing.
   
   
   F. Effects of Medication
   
   Attention must be given to the effect of medication on the child’s signs, symptoms,
      and ability to function. While drugs used to modify psychological functions and mental
      states may control certain primary manifestations of a mental disorder, e.g., hallucinations, impaired attention, restlessness, or hyperactivity, such treatment
      may not affect all functional limitations imposed by the mental disorder. In cases
      where overt symptomatology is attenuated by the use of such drugs, particular attention
      must be focused on the functional limitations that may persist. These functional limitations
      must be considered in assessing impairment severity.
   
   
   Psychotropic medicines used in the treatment of some mental illnesses may cause drowsiness,
      blunted affect, or other side effects involving other body systems. Such side effects
      must be considered in evaluating overall impairment severity.
   
   
   112.01 Category of Impairments, Mental
   
   112.02 Organic Mental Disorders: Abnormalities in perception, cognition, affect, or behavior associated with dysfunction
      of the brain. The history and physical examination or laboratory tests, including
      psychological or neuropsychological tests, demonstrate or support the presence of

      and associated deficit or loss of specific cognitive abilities, or affective changes,
      or loss of previously acquired functional abilities.

   1. For autistic disorder, all of the following:
   
   a. Qualitative deficits in the development of reciprocal social interaction; and
   
   b. Qualitative deficits in verbal and nonverbal communication and in imaginative activity;
      and
   
   
   c. Markedly restricted repertoire of activities and interests;
   
   OR
   
   2. For other pervasive developmental disorders, both of the following:

   AND
   
   B. For older infants and toddlers (age 1 to attainment of age 3), resulting in at
      least one of the appropriate age-group criteria in paragraph B1 of 112.02; or, for
      children (age 3 to attainment of age 18), resulting in at least two of the appropriate
      age-group criteria in paragraph B2 of 112.02.
   
   
   112.11 Attention Deficit Hyperactivity Disorder:
         Manifested by developmentally inappropriate degrees of inattention, impulsiveness,
      and hyperactivity.

      both A and B are satisfied.
   
   
   A. Medically documented findings of all three of the following:
   
   1. Marked inattention; and
   
   2. Marked impulsiveness; and

   112.12 Developmental and Emotional Disorders of Newborn and Younger Infants
            (Birth to attainment of age 1): Developmental or emotional disorders of infancy are evidenced by a deficit or lag
      in the areas of motor, cognitive/communicative, or social functioning. These disorders
      may be related either to organic or to functional factors or to a combination of these
      factors.
   
   
   The required level of severity for these disorders is met when the requirements of
      A, B, C, D, or E are satisfied.
   
   
   A. Cognitive/communicative functioning generally acquired by children no more than
      one-half the child’s chronological age, as documented by appropriate medical findings
      (e.g., in infants 0-6 months, markedly diminished variation in the production or imitation
      of sounds and severe feeding abnormality, such as problems with sucking, swallowing,
      or chewing) including, if necessary, a standardized test;
   
   
   OR
   
   B. Motor development generally acquired by children no more than one-half the child’s
      chronological age, documented by appropriate medical findings, including if necessary,
      a standardized test;
   
   
   OR
   
   C. Apathy, over-excitability, or fearfulness, demonstrated by an absent or grossly
      excessive response to one of the following:
   
   
   1. Visual stimulation; or
   
   2. Auditory stimulation; or
   
   3. Tactile stimulation;
   
   OR
   
   D. Failure to sustain social interaction on an ongoing, reciprocal basis as evidenced
      by:
   
   
   1. Inability by 6 months to participate in vocal, visual, and motoric exchanges (including
      facial expressions); or
   
   
   2. Failure by 9 months to communicate basic emotional responses, such as cuddling
      or exhibiting protest or anger; or
   
   
   3. Failure to attend to the caregiver’s voice or face or to explore an inanimate object
      for a period of time appropriate to the infant’s age;
   
   
   OR
   
   E. Attainment of development or function generally acquired by children no more than
      two-thirds of the child’s chronological age in two or more areas (i.e., cognitive/communicative, motor, and social), documented by appropriate medical findings,
      including if necessary, standardized testing.
