DSM-IV 299.00 FOR AUTISTIC DISORDER

A. A total of six (or more) items from (1), (2), and (3), with at

least two from (1), and one each from (2) and (3):

(1) qualitative impairment in social interaction, as manifested by at

least two of the following:

(a) marked impairment in the use of multiple nonverbal behaviors,

such as eye-to-eye gaze, facial expression, body postures, and

gestures to regulate social interaction

( failure to develop peer relationships appropriate to

developmental level

© a lack of spontaneous seeking to share enjoyment, interests, or

achievements with other people (e.g., by a lack of showing, bringing,

or pointing out objects of interest)

(d) lack of social or emotional reciprocity

(2) qualitative impairments in communication, as manifested by at

least one of the following:

(a) delay in, or total lack of, the development of spoken language

(not accompanied by an attempt to compensate through alternative

modes of communication such as gesture or mime)

( in individuals with adequate speech, marked impairment in the

ability to initiate or sustain a conversation with others

© stereotyped and repetitive use of language or idiosyncratic

language

(d) lack of varied, spontaneous make-believe play or social imitative

play appropriate to developmental level

(3) restricted, repetitive, and stereotyped patterns of behavior,

interests, and activities as manifested by at least one of the

following:

(a) encompassing preoccupation with one or more stereotyped and

restricted patterns of interest that is abnormal either in intensity

or focus

( apparently inflexible adherence to specific, nonfunctional

routines or rituals

© stereotyped and repetitive motor mannerisms (e.g., hand or finger

flapping or twisting or complex whole-body movements)

(d) persistent preoccupation with parts of objects

B. Delays or abnormal functioning in at least one of the following

areas, with onset prior to age 3 years: (1) social interaction, (2)

language as used in social communication, or (3) symbolic or

imaginative play.

C. The disturbance is not better accounted for by Rett's Disorder or

Childhood Disintegrative Disorder.

DSM-IV 299.80 FOR PERVASIVE DEVELOPMENTAL DISORDER - NOT OTHERWISE

SPECIFIED

This category should be used when there is a severe and pervasive

impairment in the development of reciprocal social interaction or

verbal and nonverbal communication skills, or when stereotyped

behavior, interests, and activities are present, but the criteria are

not met for a specific pervasive developmental disorder,

schizophrenia, schizotypal personality disorder, or avoidant

personality disorder. For example, this category includes " atypical

autism " --presentations that do not meet the criteria for autistic

disorder because of late age of onset, atypical symptomatology, or

subthreshold symptomatology, or all of these.

DSM-IV 299.80 FOR ASPERGER'S DISORDER

A. Qualitative impairment in social interaction, as manifested by at

least two of the following:

(1) marked impairment in the use of multiple nonverbal behaviors,

such as eye-to-eye gaze, facial expression, body postures, and

gestures to regulate social interaction

(2) failure to develop peer relationships appropriate to

developmental level

(3) a lack of spontaneous seeking to share enjoyment, interests, or

achievements with other people (e.g., by a lack of showing, bringing,

or pointing out objects of interest to other people)

(4) lack of social or emotional reciprocity

B. Restricted, repetitive, and stereotyped patterns of behavior,

interests, and activities, as manifested by at least one of the

following:

(1) encompassing preoccupation with one or more stereotyped and

restricted patterns of interest that is abnormal either in intensity

or focus

(2) apparently inflexible adherence to specific, nonfunctional

routines or rituals

(3) stereotyped and repetitive motor mannerisms (e.g., hand or finger

flapping or twisting, or complex whole-body movements)

(4) persistent preoccupation with parts of objects

C. The disturbance causes clinically significant impairment in

social, occupational, or other important areas of functioning.

D. There is no clinically significant general delay in language

(e.g., single words used by age 2 years, communicative phrases used

by age 3 years).

E. There is no clinically significant delay in cognitive development

or in the development of age-appropriate self-help skills, adaptive

behavior (other than in social interaction), and curiosity about the

environment in childhood.

F. Criteria are not met for another specific pervasive developmental

disorder or schizophrenia.

DSM-IV 299.80 FOR RETT'S DISORDER

A. All of the following:

(1) apparently normal prenatal and perinatal development

(2) apparently normal psychomotor development through the first 5

months after birth

(3) normal head circumference at birth

B. Onset of all of the following after the period of normal

development:

(1) deceleration of head growth between ages 5 and 48 months

(2) loss of previously acquired purposeful hand skills between ages 5

and 30 months with the subsequent development of stereotyped hand

movements (i.e., hand-wringing or hand washing)

(3) loss of social engagement early in the course (although often

social interaction develops later)

(4) appearance of poorly coordinated gait or trunk movements

(5) severely impaired expressive and receptive language development

with severe psychomotor retardation

DSM 299.10 FOR CHILDHOOD DISINTEGRATIVE DISORDER

A. Apparently normal development for at least the first 2 years after

birth as manifested by the presence of age-appropriate verbal and

nonverbal communication, social relationships, play, and adaptive

behavior.

B. Clinically significant loss of previously acquired skills (before

age 10 years) in at least two of the following areas:

(1) expressive or receptive language

(2) social skills or adaptive behavior

(3) bowel or bladder control

(4) play

(5) motor skills

C. Abnormalities of functioning in at least two of the following

areas:

(1) qualitative impairement in social interaction (e.g., impairment

in nonverbal behaviors, failure to develop peer relationships, lack

of social or emotional reciprocity)

(2) qualitative impairments in communication (e.g., delay or lack of

spoken language, inability to initiate or sustain a conversation,

stereotyped and repetitive use of language, lack of varied make-

believe play)

(3) restricted, repetitive, and stereotyped patterns of behavior,

interests, and activities, including motor stereotypes and mannerisms

D. The disturbance is not better accounted for by another specific

Pervasive Developmental Disorder or by schizophrenia.
