The feasibility and reliability of the German form of the revised parental interview to diagnose autism (Autism Diagnostic Interview-Revised, ADI-R) was investigated in this study. Brief examples of the description of formerly and currently used diagnostic guidelines are given and the outline of the interview algorithm which establishes thresholds for inclusion criteria. An excellent-to-good reliability could be demonstrated for the main symptoms according to the classification rules of the ICD-10 and DSM-IV for a sample of autistic subjects at different ages and intellectual levels. The results approve the use of this interview for research and clinical purposes.

This study compared four systems for the diagnosis of autism (DSM-III, DSM-III-R, DSM-IV, and ICD-10) with two empirically derived taxa of autism, and with three social subgroups of autism (Aloof, Passive, and Active-but-Odd) in 194 preschool children with salient social impairment. There were significant behavior and IQ differences between autistic and other-PDD groups for all four diagnostic systems, and a significant association was found (a) for Taxon B, diagnoses of autism, and the Aloof subgroup, and (b) for Taxon A, other-PDD, and the Active-but-Odd subgroup. Findings offer support for two major overlapping continua within idiopathic Pervasive Developmental Disorder.

The authors investigated the validity of Asperger Syndrome (AS) by comparing the neuropsychological profiles in this condition and Higher-Functioning Autism (HFA). Diagnostic assignment followed a stringent procedure based on ICD-10 research criteria for the two disorders. The groups had comparable age and Full Scale IQ distributions. The groups differed significantly in 11 neuropsychological areas. The profile obtained for individuals with AS coincided closely with a cluster of neuropsychological assets and deficits captured by the term nonverbal learning disabilities, suggesting an empirical distinction from HFA.

Revised versions of diagnostic manuals, the International Classification of Diseases (ICD-10), and the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) all operate with several subgroups in the autistic spectrum. Five of the subgroups are identical in the two manuals, but ICD-10 contains five in addition. 132 children were diagnosed using ICD-10, DSM-IV, DSM-III-R, the Childhood Autism Rating Scale (CARS), and the Autistic Behavior Checklist (ABC). Five out of ten alternative subgroups of Pervasive Developmental Disorders (PDD) were identified in a population of developmentally impaired children. These subgroups were the same in the two manuals; the additional ones in ICD-10 were not identified. With the exception of the groups Disintegrative Disorder and Rett syndrome, significant differences were found between all the subgroups within the PDD spectrum and between the PDD group and the non-PDD group. Some problems connected with the guidelines in the ICD-10 manual are discussed.

Asperger syndrome (AS) is a pervasive developmental disorder recently introduced as a new diagnostic category in the ICD-10 and the DSM-IV. Along with motor clumsiness, pedantic speech has been proposed as a clinical feature of AS. However, few attempts have been made to define and measure this symptom. We studied 17 patients with AS (ICD-10; 14 male, 3 female; mean age 16.4 years, mean full-scale IQ 97) and compared them with a control group of 13 patients with normal-intelligence autism or high-functioning autism (HFA) (ICD-10/DSM-III-R; 12 male, 1 female; mean age 15.5 years, mean full-scale IQ 81.2). An operational definition of pedantic speech was formulated and a rating scale devised. 13 (76%) of the AS patients were rated as pedantic compared to 4 (31%) of the HFA group (chi 2 = 6.3; p = .01). Results suggest that pedantic speech is common in AS and may help differentiate AS from high-functioning autism.

To test the validity of Asperger syndrome (AS) as defined in ICD-10, 26 patients (age range, 3.5 to 12 years) with AS and 16 patients (age range, 3 to 11.5 years) with high-functioning (IQ > 90) ICD-10 atypical autism (HAA) were compared on 64 clinical variables including obstetric risk factors, early developmental landmarks, IQ, autistic symptoms on the CARS-TV, epileptic EEG abnormalities and epilepsy. AS did not differ significantly from HAA on all but total and four item scores (i.e. imitation, visual responsiveness, auditory responsiveness and non-verbal communication) on the CARS-TV, in which AS scored significantly lower than HAA. A discriminant function based on imitation and auditory responsiveness predicted 76.2% of the 42 cases. The small difference from HAA indicates that AS is better to be regarded as the highest-functioning end of the PDD spectrum, rather than a valid subtype of PDD. However, the autistic symptom profile less distorted in AS than HAA may warrant a further study on its validity.

Natural history of infantile autism goes from its first description to current classifications. Most authors agree upon the perfect character of Kanner's description in 1943. But its situation in the nosography has much developed. The parution of 4th edition of Diagnostic and Statistical Manual of mental disorders (DSM IV) bring us to analyse this evolution and the place of autistic disorders in the pervasive developmental disorders, with this of associated pathologies. The comparison of current classifications (DSM IV, ICD 10, CFTMEA) allows us to do correspondence between each diagnostic category in psychosis or developmental disorders of these classifications. It exists a real concordance between DSM IV and ICD 10. The french classification of child and adolescent mental disorders (CFTMEA) proposes original categories.

This follow-up study reports data on 18 children fulfilling the ICD-10 criteria for childhood autism (n = 9) and Asperger syndrome (n = 9). In connection with the present study the original child psychiatric records were reassessed according to the ICD-10 criteria. The children were followed over a period of 30 years. The mean age at the time of study was 38 years. The results show that in adulthood the autistic patients had a poorer outcome than children with Asperger syndrome as regards education, employment, autonomy, marriage, reproduction and the need for continuing medical and institutional care. Particular attention is given to pharmacotherapy and the relationship between the childhood disorder and psychiatric morbidity in adult life.

The frequency and clinical presentation of autism in 28 probands with tuberous sclerosis complex (TSC) are reported and risk factors that may influence the development of autism in TSC are examined. Eight probands meet ICD-10 and DSM-IV criteria for autism, an additional 4 meet criteria for pervasive developmental disorder (PDD). Twelve TSC probands with autism/PDD are compared to 16 TSC probands without these conditions for factors which may underlie the association of autism and TSC. A specific seizure type, infantile spasms, as well as mental retardation, are increased in the TSC, autistic/PDD group. Furthermore, rates of social phobia and substance abuse are elevated among first-degree relatives of TSC probands with autism compared to first-degree relatives of TSC probands without autism. Implications of these findings in understanding the association of autism and TSC are discussed.

In 1994 Hans Asperger (1906-80), an Austrian physician, described a group of children with impaired social interaction and communication abilities. The name of this disorder today is Asperger's syndrome, and it is currently defined under the category of pervasive developmental disorder in DSM-IV and ICD-10. In this article the following aspects of Asperger's syndrome are focused on: personality, epidemiology, etiology, examination, differential diagnosis, management and prognosis. The article is based on a literature study. Asperger's syndrome seems to be considerably more common than "classic" autism. The syndrome is much more common in boys than in girls. The clinical characteristics of Asperger's syndrome are probably influenced by many factors, including organic and genetic factors. Asperger's syndrome is the term applied to the highest functioning end of the autism scale. There are several commonalities between Asperger's syndrome and autism, namely impairment of social interaction and communication abilities, and range of interests and activities. Differences exist primarily in the degree of impairment in language and cognitive development. Differential diagnosis, examination and management are discussed. There is a need for further research. It is important that the diagnostic criteria for Asperger's syndrome are as uniform as possible, and that they do not overlap with infantile autism.
