The brainstem-cerebellar circuitry has been implicated in the pathophysiology of autism for several decades. Recent magnetic resonance imaging (MRI) studies of the posterior fossa have reported various abnormalities, the most noteworthy of which has been selective hypoplasia of the neocerebellar vermis. However, these initial MRI studies are limited by problems in both subject and control selection. The present study was undertaken to further investigate these MRI findings and the role of the cerebellum in autism, taking into consideration these methodologic issues. Eighteen high-functioning autistic subjects were recruited and matched with 18 normal controls on the basis of age, gender, IQ, race and socioeconomic status (SES). The midsagittal areas of the cerebellar vermis, vermal lobes, and the fourth ventricle were measured on 3 mm contiguous magnetic resonance images. Mean areas and standard deviations were comparable for all regions of interest and no statistically significant between-group differences were found. These negative findings argue against theories of autism based on gross structural abnormalities of the cerebellum. Previous reports of posterior fossa abnormalities may be related to technical and methodological factors, based on comparison of extant literature and recently available normative data.

Stress profiles in 18 mothers vs 12 fathers of children with autism were compared on three measures, the Questionnaire on Resources and Stress, the Coping Health Inventory for Parents, and the Beck Depression Inventory. Mothers showed significantly more stress than fathers on each inventory, with a pattern suggesting stress may be related to the differing responsibility assigned to child rearing for each parent.

Twenty-two members of 18 families with autism have been examined for the presence of mutations and abnormal methylation in the FMR-1 region at Xq27.3. All patients fulfilled diagnostic criteria of infantile autism. A characteristic pattern of insertion and methylation were detected after Southern blot analysis in 7 autistic individuals expressing the fragile site at Xq27.3. Normal DNA patterns were observed in 15 autistic boys cytogenetically negative for the fragile site. The results indicate a lack of involvement of the FMR-1 region in infantile autists negative for fragile X expression.

Autism is currently detected only at about three years of age. This study aimed to establish if detection of autism was possible at 18 months of age. We screened 41 18-month-old toddlers who were at high genetic risk for developing autism, and 50 randomly selected 18-month-olds, using a new instrument, the CHAT, administered by GPs or health visitors. More than 80% of the randomly selected 18-month-old toddlers passed on all items, and none failed on more than one of pretend play, protodeclarative pointing, joint-attention, social interest, and social play. Four children in the high-risk group failed on two or more of these five key types of behaviour. At follow-up at 30 months of age, the 87 children who had passed four or more of these key types of behaviour at 18 months of age had continued to develop normally. The four toddlers who had failed on two or more of these key types of behaviour at 18 months received a diagnosis of autism by 30 months.

Classifications have to meet a variety of purposes. Clinical and research needs are different and there is much to be said for separate clinical and research schemes. Care is needed to ensure that classifications provide an appropriate medium for teaching about diagnosis and do not cause difficulties when used as a "passport" to resources. Principles of classification are considered in relation to the need to take course, as well as symptomatology, into account, and with respect to the neuropsychiatric interface. The value of a multiaxial approach is noted. The pros and cons of autism and pervasive developmental disorders (PDD) as an overall descriptive term, of lumping or splitting, and of different choices with respect to PDD subcategories are discussed.

ICD-10 draft research criteria for childhood autism were applied to a previously published data set comparing DSM-III and DSM-III-R to clinicians' diagnoses of autism. The ICD-10 approach paralleled clinicians' patterns of diagnosis and, to a lesser extent, the DSM-III system. Relative to either clinicians, DSM-III, or ICD-10 the DSM-III-R system overdiagnosed the presence of autism. Implications for research and for future revision of diagnostic criteria are discussed.

The purpose of this study was to clarify the issue of whether DSM-III-R (American Psychological Association [APA], 1987) over- or underdiagnoses autism by comparing this diagnostic system to a well-established objective measure of diagnosis, the Childhood Autism Rating Scale (CARS). A secondary goal was to determine which of the 16 criteria are the best discriminators of autism. DSM-III-R, CARS, and clinical diagnoses of 138 consecutive admissions to a statewide program for the diagnosis and treatment of autistic and related communication-handicapped individuals (Division TEACCH in North Carolina) were compared. Results indicated a generally high degree of agreement on the diagnosis of autism using the three systems. Within this treatment-oriented program, the CARS and clinical ratings diagnosed a greater number of cases as autistic than did the DSM-III-R criteria, suggesting that DSM-III-R slightly underdiagnosed autism. The criteria that most strongly related to the diagnosis of autism regardless of the system were lack of awareness of others, abnormal social play, an impaired ability to make friends, abnormal nonverbal communication, stereotypic body movements, and restricted range of interests.
