OBJECTIVE This study evaluated the diagnostic process and prevalence rates of Asperger syndrome (AS) according to the DSM-IV, ICD-10, and criteria developed by Gillberg and Gillberg and by Szatmari and colleagues and clarified confusion about AS. METHOD An epidemiological study of 5,484 eight-year-old children in Finland, 4,422 (80.6%) of whom rated on the high-functioning Autism Spectrum Screening Questionnaire by parents and/or teacher, 125 of them screened and 110 examined by using… 
Autism spectrum disorders according to DSM-IV-TR and comparison with DSM-5 draft criteria: an epidemiological study.
Comparison of Diagnostic Methods for Asperger Syndrome
TLDR
The aim of this study was to compare four diagnostic sets of criteria for Asperger syndrome: the ICD-10, the DSM-IV, the Gillberg & Gillberg, and the Szatmari criteria.
Validation of the Finnish Autism Spectrum Screening Questionnaire (ASSQ) for Clinical Settings and Total Population Screening
TLDR
For Finnish higher-functioning primary school-aged, 7- to 12-year-olds, the optimal cut-off score was 30 in clinical settings and 28 in total population screening using summed ASSQ scores of parents’ and teachers’ ratings.
Autism spectrum disorders : an epidemiological and clinical study
TLDR
The results indicate the need to standardize the diagnostic criteria for ASDs and suggest the ICD-11 criteria should be uniform and harmonize with DSM-5.
Prevalence and characteristics of autistic spectrum disorders in the ALSPAC cohort
TLDR
It is concluded that the prevalence of ASD diagnosed at 11 years in a UK representative population‐based sample is at least 51.1/10 000.
Autism spectrum symptoms in children with neurological disorders
TLDR
The ASSQ identifies a high rate of ASD symptoms in children with neurological disorders, and a large number of children screened in the positive range for ASD, suggesting that health care professionals should be aware of potential ASD related problems in childrenwith neurological disorders.

A SPERGER SYNDROME IN MALES OVER TWO DECADES
TLDR
AS in males, when considered as an ASD was a relatively stable diagnosis over almost two decades, a majority met criteria of at least one other current comorbid disorder.
Comorbid Psychiatric Disorders Associated with Asperger Syndrome/High-functioning Autism: A Community- and Clinic-based Study
The present study identifies the prevalence and types of comorbid psychiatric disorders associated with Asperger syndrome (AS)/high-functioning autism (HFA) in a combined community- and clinic-based
When does the Autism Spectrum Screening Questionnaire (ASSQ) predict autism spectrum disorders in primary school-aged children?
TLDR
In the whole total population, low positive correlation was found between parents’ and teachers’ ratings for the Finnish version of the Autism Spectrum Screening Questionnaire, while in the sample of high-scoring children the correlation turned out to be negative.

Asperger’s Syndrome: A Comparison of Clinical Diagnoses and Those Made According to the ICD-10 and DSM-IV
TLDR
Results contrast with those of others who have stated that the diagnosis of AS using ICD-10/DSM-IV criteria is ‘virtually impossible’, and it is suggested that this is due to limitations inherent in these criteria.
Autism in Northern Finland
TLDR
In this study, almost 50% of the autistic cases had a tested IQ above 70, and the degree of autism, as assessed by the Childhood Autism Rating Scale (CARS), varied from mild autistic features in 8.5% through moderate in 58.0%.

TLDR
A total population study of Asperger syndrome using a two-stage procedure and findings obtained using Szatmari et al.'s and ICD-10 draft criteria for the disorder are described.
Pervasive developmental disorders in preschool children: confirmation of high prevalence.
TLDR
The rate of reported pervasive developmental disorders has increased, and the authors found a rate of 62.6 per 10,000 in a previous study of preschoolers in Stafford, U.K, suggesting a stable incidence.
Asperger's Syndrome: A Review of Clinical Features
TLDR
The sex ratio, family history, and presence of neurologic disease in some Asperger's Syndrome cases, suggest that the etiology of the disorder is similar to that in autism.
Pervasive developmental disorders in preschool children.
TLDR
The authors' results suggest that rates of PDD are higher than previously reported, and attention is nevertheless drawn to the important needs of a substantial minority of preschool children.
Autism and Related Disorders: Epidemiological Findings in a Norwegian Study Using ICD-10 Diagnostic Criteria
TLDR
In this Norwegian population of children ages 3–14 years the minimum prevalence estimate for childhood autism was 4–5 per 10,000 using ICD-10 research criteria, and did not confirm the high estimates suggested more recently.
Subjective face recognition difficulties, aberrant sensibility, sleeping disturbances and aberrant eating habits in families with Asperger syndrome
TLDR
An aberrant processing of sensory information appears to be a common feature in Asperger Syndrome and these associated clinical traits may well be reflected by the behavioural characteristics of these individuals.
Autism and Asperger syndrome: Clinical and neurobiological aspects of Asperger syndrome in six family studies
TLDR
Since the seminal paper by Wing (1981), interest and work in the field have so grown that one senses the presence of a true diagnostic entity – at least from the clinical point of view – which for many years has haunted child and adult psychiatrists alike.

TLDR
The CHAT can be used to identify cases of autism and related pervasive developmental disorders at 18 months of age and has a sensitivity of 38% and a specificity of 98% for identifying CA.
