Autism

This article examines the existence, description, perception, treatment, and outcome of symptoms consistent with autistic disorder in nineteenth-century London, England, based on case histories from the notes of Dr William Howship Dickinson at Great Ormond Street Hospital for Children. Three cases meeting the DSM-IV criteria for autistic disorder are described in detail. Other cases in which autistic traits are described are briefly summarized. The article explores the environment of contemporary medical practice, beliefs about childhood brain disorders, and social practice regarding children with brain disorders, and the impact of these factors on assessment and treatment. It correlates Dickinson’s observations with current research on autism, providing information about children with autism before the condition was formally named in 1943.

This study aimed to determine if relatives of children with autism and less severe pervasive developmental disorders (PDDs) have higher rates of various components of the broad autistic phenotype. Psychiatric and medical disorders were investigated. Parents of children with PDDs were selected from an epidemiological survey and compared with parents of control children with non-autistic developmental problems. Rates of abnormalities and disorders were compared in relatives of 79 cases and 61 controls. Medical and autoimmune disorders in both groups were endorsed by few relatives. Specific developmental disorders were commoner in parents of controls. Depression and anxiety were significantly more prevalent in mothers of children with PDDs. Significantly more PDD children had at least one firstdegree relative with anxiety and one second-degree relative with OCD. PDDs were commoner in first-degree relatives. The implications of the findings for the definition of the broad phenotype of autism are discussed.

This study analyses the prevalence of ASD, comorbidity, educational provision and ability in autistic children in a single health district, born between 1983 and 1996. The number of recorded diagnoses doubled over a 4 year period. This appeared to be due to greater recognition of ASD in more able children, in children initially presenting with ADHD, and possibly in females. ADHD accounted for a substantial proportion of comorbidity. Age at diagnosis appeared to be related to school placement. Cognitive ability levels ranging from more than three standard deviations below the mean to more than one standard deviation above the mean were found in the moderate and severe learning difficulty school population as well as in the mainstream population. Exceptionally low levels of verbal ability were present in a high proportion of mainstream pupils. Measured levels of cognitive function show poor relationship with actual educational placement.

A population-based survey was conducted among 152,732 Finnish children and adolescents aged under 16 years and living in northern Finland. Diagnoses and associated medical conditions were derived from the hospital and institutional records of this area. One hundred and eighty-seven children with DSM-IV autistic disorder were identified. Associated medical disorders or associated disorders of known or suspected genetic origin were found in 12.3 percent, including tuberous sclerosis, Down syndrome, fragile X syndrome, Klinefelter syndrome, XYY syndrome, chromosome 17 deletion, chromosome 46, XX, dup(8)(p) and mitochondriopathy. Other associated medical disorders identified were epilepsy, hydrocephalus, foetal alcohol syndrome and cerebral palsy. Hearing impairments were found in 8.6 percent and severe impairment of vision in 3.7 percent of the individuals with autistic disorder. Medical disorders seem to have a special impact on the genesis of autistic disorder and need to be thoroughly examined in each child with autistic disorder.

A sample of 37 children aged 4–7 years who all showed some autistic features was investigated. Children with a primary diagnosis of autism were compared with those diagnosed with a language disorder, on behaviours within four domains; social behaviour, imaginative activities, repetitive behaviour and communication. The aim was to identify potentially differentiating features of the two groups using observational ratings and questionnaire measures provided by parents and teachers. Information on participants’ intelligence and language skills was also collected. The children with autism showed greater deficits in joint attention, functional play and pragmatic language, and engaged in more repetitive behaviours, than the language disordered children. However, the groups did not differ significantly on formally assessed language skills. A cluster analysis produced three groups of children varying in level of functioning and parent-rated behaviours. The results are informative for clinicians dealing with the challenge of differential diagnosis.

Increasing numbers of children with autism spectrum disorder (ASD) are diagnosed in the preschool years, and their educational progress must be monitored. Parent questionnaire data can augment psychometric assessments and individual planning at low cost. One hundred and twenty-five parents of UK children who entered dedicated autism primary schools and units in two consecutive calendar years were asked to complete three questionnaires. Fifty-seven parents repeated the questionnaire measures one year later. Encouraging developmental progress was observed on the Vineland Adaptive Behavior Scales–Screener. Symptom severity as measured by the Social Communication Questionnaire did not change over time. The pattern of change scores on the Autism Treatment Evaluation Checklist was mixed, and confounding disadvantages this questionnaire. The study demonstrated that it is possible to collect useful information on the progress of children with ASD using parents as informants. Such data would assist in judging claims regarding developmental progress within particular programmes.

The aim of the study was to evaluate and compare the efficacy of short-term psychoeducational treatment in children with autism and reactive attachment disorder (RAD). Ten boys with autism aged 24–66 months and 11 children with RAD (nine boys and two girls) aged 30–70 months were included in the study. The Ankara Developmental Screening Inventory was used to monitor progress following a 14-session psychoeducational programme. This focused on establishing a reciprocal-dyadic interaction between children and their caregivers and it also provided an educational programme for emotional, social, and language development. Although both groups showed significant changes on all scales of the ADSI, the children with RAD showed greater improvement than the autism group in their total development score, on the language-cognitive subscale, and in social/self-care abilities.
