Children with diagnoses of either autism or Asperger's syndrome were matched on measures of verbal mental age with nonautistic control children. They were tested on their abilities to process both facial and nonfacial stimuli. There were no significant differences between the low ability autistic and control groups, but the high ability autistic and Asperger's children performed significantly worse than controls across all tests. Group averages masked substantial individual variation. The results are seen as indicating a general perceptual deficit that is not specific to faces or emotions. This appears to be a common correlate of autism and Asperger's syndrome, rather than a core symptom.

Asperger's syndrome (AS) is a new diagnosis in the 10th edition of International Classification of Diseases (ICD-10). AS is closely related to infantile autism and belongs to the so-called pervasive developmental disorders. The characteristics of the disorder are qualitative abnormalities in reciprocal social interaction, restricted and repetitive patterns of behaviour and interests and often motor clumsiness and problems with nonverbal and social aspects of communication. The sex ratio is about eight boys to one girl and the prevalence among schoolage boys is about 0.3%. The abnormalities normally persist into adulthood. Early diagnosis and a combination of social, educational and psychiatric interventions are necessary to relieve the stress on the person with AS and his family. Differential diagnoses and assessment are discussed.

Investigated the use of cohesive links to create a reciprocal conversation in individuals with autism, Asperger syndrome, and a control group of children and adolescents with nonspecific social problems. All subjects engaged in a 10-minute conversation with an examiner that touched on various topics. The conversation was audiotaped, transcribed, and coded blindly for several types of cohesive links. Compared to controls, the higher functioning autistic group referred less to a previous stretch of the conversation and more to an aspect of the physical environment. The Asperger group, on the other hand, was very similar to the controls except they made more unclear references that were difficult to interpret. Implications of these findings for understanding the communicative failure of subjects with pervasive developmental disorder are discussed.

The authors obtained neurological assessments and psychiatric family history data for 40 children with autistic spectrum disorders (autism, Asperger syndrome and pervasive developmental disorder). Neurological evaluation included EEG, MRI, karyotyping and positron emission tomography as indicated. Family history data were obtained from family members during long-term follow-up. 20 probands had positive neurological findings, 18 with negative family history. 14 had no neurological findings and positive family histories; they tended to have higher function. Six had neither, and two had both. The segregation of neurological findings and familial affective disorder was highly significant. These findings suggest that an important subgroup of autistic spectrum disorders may be related etiologically to familial major affective disorders, and may represent the early-life onset of a severe phenotype of major affective, particularly bipolar, disease.

Multidisciplinary data from 166 children with autistic spectrum disorders were subjected to cluster analysis. Cross-validation between random halves of the sample showed acceptable consistency of the clustering method. Four clinically meaningful subtypes emerged from the analysis. They did not differ in demographic characteristics but did show, on average, distinct differences in behavioral and cognitive areas. Over half of the sample fell into a subtype described as typically autistic with abnormal verbal and nonverbal communication, aloofness, impaired social skills, and sensory disturbances. Another 19% were similarly autistic but with moderate to severe mental handicap. The remaining children formed two subtypes: a high-functioning Asperger-like group who were overactive and aggressive, and a small group who were impaired in social and language skills, had restricted interests, and a family history of learning problems. This study highlights important differences among children with autism and emphasizes relationships between cognitive functioning and subtypes of the disorder.

We report here the case study of a patient (E.C.) with an Asperger syndrome, or autism with quasinormal intelligence, who shows an outstanding ability for three-dimensional drawing of inanimate objects (savant syndrome). An assessment of the subsystems proposed in recent models of object recognition evidenced intact perceptual analysis and identification. The initial (or primal sketch), viewer-centered (or 2-1/2-D), or object-centered (3-D) representations and the recognition and name levels were functional. In contrast, E.C.'s pattern of performance in three different types of tasks converge to suggest an anomaly in the hierarchical organization of the local and global parts of a figure: a local interference effect in incongruent hierarchical visual stimuli, a deficit in relating local parts to global form information in impossible figures, and an absence of feature-grouping in graphic recall. The results are discussed in relation to normal visual perception and to current accounts of the savant syndrome in autism.

This paper describes Asperger's syndrome, a disease similar to the autistic disorder, delineated for the first time by Asperger in 1944, just a few months after L. Kanner described infantile autism. Although, according to the epidemiological data, it occurs far more frequently than infantile autism, in practice this diagnosis is rarely established. Asperger's syndrome is defined as autistic syndrome among children with relatively high degree of intellectual functions, with marked disorder of speech and motoricity and interest confined to a very specified area. Learning is mechanical and routine and games uninventive. Children lack the need for age peer company. Boys are affected ten times more frequently than girls.

Short unstructured social interactions between a volunteer interviewer, an adult with autism of Asperger type, and a control subject with a schizoid personality disorder were video-recorded. Asperger subjects tended to look less at the other person, to make more self-stimulatory gestures, and to look at the interviewer significantly less than normal subjects, and substantially less than schizoid subjects, during the periods when the interviewer was vocalizing although there were no such differences when the interviewer was listening. We suggest that the gaze avoidance of autism may in actuality be a lack of expected gaze (e.g., gaze when the other person is talking) rather than an absolute avoidance, and suggest that a lifelong absence of gaze response to social cues including speech could explain a number of the developmental features of autism including lack of joint attention with others, lack of understanding and affective response to others, and poor discrimination of facial expressions.

This Grand Rounds is concerned with the classification of Asperger's syndrome and its continuity/discontinuity with autism. Information on a 15-year-old with the condition is presented as are data on other family members. The proband exhibited a longstanding pattern of marked deficits in social interaction, motor awkwardness, and unusual, circumscribed interest consistent with a diagnosis of Asperger's syndrome. Both the proband and his father exhibited unusual discrepancies between verbal and performance (nonverbal) cognitive abilities favoring the former. Deficits were observed in the social use of language. Father and son had similar abnormalities on magnetic resonance imaging examination. Potential differences between higher-functioning autism and Asperger's syndrome are important areas for future research.

Asperger syndrome (AS) is a pervasive developmental disorder widely regarded as a mild variant of autism. To investigate if AS is associated with a history of fewer obstetric insults compared to autism, we examined the developmental history and obstetric records of 10 males with AS (mean full scale IQ 95.3), and compared them with 10 autistic males with a full scale IQ of 70 or above (so-called high-functioning autism; mean full scale IQ 82.6). Males with AS showed a trend toward lower Apgar scores at one minute (chi-square = 4; df = 1; P = 0.04) and were more likely to have been born to mothers outside the optimal age group of 20-30 years (chi-square = 5; df = 1; P = 0.02). They were also less likely to have been irritable and floppy as infants (chi-square = 3.8; df = 1; P = 0.05). However, the total optimality scores did not differ significantly between the two groups.
