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, andgestures to regulate social
interaction
(b) failure to
develop peer relationships appropriate to develop mental level
(c) a lack of
spontaneous seeking to share enjoyment, interests,or achievements
with

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)
(b) in
individuals with adequate speech, marked impairment in the ability to initiate
or
sustain a conversation with others
(c) stereotyped
arid 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
(b)
apparently inflexible adherence to specific, nonfunctional routines or rituals
(c)
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
(3) symbolic or imaginative play.
C. The disturbance is not better accounted for by Rett's Disorder or
Childhood
Disintegrative 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
(e.g.,
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
A. Apparently normal development for at least the first 2 years after birth
as manifested by
the presence of age-appropriate verbal and non verbal
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 ac least two of the following areas:
(1) qualitative impairment 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 makebelieve play)
(3) restricted, repetitive, and stereotyped
patterns of behavior, interests, and activities,
including motor
stereotypies and mannerisms
D. The disturbance is not better accounted for by another specific
Pervasive Developmental Disorder or by Schizophrenia.
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.
This category should be used when there is a sever 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 PDD, Schizophrenia, Schizotypal
Personality Disorder, or Avoidant Personality Disorder. For example, this category
includes "atypical autism" - presentations that do not meet the criteria fro
Autistic Disorder because of late age at onset, atypical symptomatology, or subthreshold
symptomatology, or all of these.
