The clinical features, course, aetiology, epidemiology, differential diagnosis and management of Asperger's syndrome are described. Classification is discussed and reasons are given for including the syndrome, together with early childhood autism, in a wider group of conditions which have, in common, impairment of development of social interaction, communication and imagination.

Children with typical autism, other early childhood psychoses and severe mental retardation without autistic behaviour were identified in an epidemiological study in an area of South East London. The social class distribution of their fathers was examined and no significant differences were found between the groups, nor in a comparison with the general population of the area. Fathers of children with autism and related conditions referred to an out-patient clinic with a special interest in autism, mostly at their own request, and fathers joining the National Society for Autistic Children, were of higher social class than both the average for England and Wales and the fathers of the study children. Joining the NSAC during its early years, and keeping up membership were also linked with higher social class. The findings supported the view that reports of a social class bias in autism may be explained by factors affecting referral and diagnosis.
The prevalence, in children aged under 15, of severe impairments of social interaction, language abnormalities, and repetitive stereotyped behaviors was investigated in an area of London. A "socially impaired" group (more than half of whom were severely retarded) and a comparison group of "sociable severely mentally retarded" children were identified. Mutism or echolalia, and repetitive stereotyped behaviors were found in almost all the socially impaired children, but to a less marked extent in a minority of the sociable severely retarded. Certain organic conditions were found more often in the socially impaired group. A subgroup with a history of Kanner's early childhood autism could be identified reliably but shared many abnormalities with other socially impaired children. The relationships between mental retardation, typical autism, and other conditions involving social impairment were discussed, and a system of classification based on quality of social interaction was considered.

The design, administration, and scording of the first edition of the Children's Handicaps, Behavior & Skills (HBS) structural interview schedule, intended to elicit information concerning metally retarded or psychotic children, are described. A high level of reliability was achieved with experienced interviewers and good informants. In a study of 104 such children, the levels of overall agreement between parent and professional informants on the 62 sections of the schedule were, in general, 70% or above. Agreement was better for rating absence of skills or behavioral abnormalities than for rating their presence. This tendency was particularly marked for the behavioral abnormaliteis. Parents, when compared with professional workers, tended to describe their children as having higher developmental skills, more social contact but also more repetitive and difficult behavior.

The results of surveys and inquiries to identify autistic children, carried out in England and Wales, the U.S.A. and Denmark, are compared. Three studies, in each of which either a total population of children or a wide range of handicapped children was screened, using case-note inspection and interviews, all estimated the prevalence of the autistic syndrome to be between four and five children per 10,000 aged under 15 years. Inquiries that counted diagnosed cases only or that relied upon local authority records produced much lower prevalence rates for the autistic syndrome. The reasons for this are examined, and the implications for prevalence studies of handicapping conditions are discussed.
Kanner's descriptions of the children showing the abnormal behaviour pattern he observed and named "early infantile autism" are summarized. E.A. and N. Tinbergen's ethological theory of the aetiology of this syndrome is outlined and criticized. The major problem in evaluating this theory, apart from the absence of any evidence in its favour, is the lack of precision with which the Tinbergens use the terms "autism" and "Kanner's syndrome".
The characteristics of language and other forms of communication in normal and autistic children are described. The main basis of comparison is the extent to which each group can comprehend and use spoken and nonspoken language and also develop inner language. It is suggested that the central problem in early childhood autism is an impairment of complex symbolic function affecting all forms of communication. This problem can occur on its own, but, in the majority of cases, it is associated with other impairments of the central nervous system. The relationship of early childhood autism to mental retardation and to normal intellectual function is discussed.
