Eye Disorders among Adult People Diagnosed with Infantile Autism in Childhood: A Longitudinal Case Control Study.

Purpose: The objective of this study was to compare the prevalence and types of eye disorders in a clinical sample of 118 adult people diagnosed with infantile autism (IA) during childhood with 336 sex- and age-matched controls from the general population.

Methods: All participants were screened through the nationwide Danish National Hospital Register. The average observation time of both groups was 37.

The Sex Ratio of Full and Half Siblings of People Diagnosed With ADHD in Childhood and Adolescence: A Danish Nationwide Register-Based Cohort Study.

Objective: It has been suggested that high levels of prenatal testosterone exposure are implied in the etiology of male preponderance disorders such as autism spectrum disorder and ADHD. Within this scope, we studied the sex ratio (proportion of males) in siblings of individuals diagnosed with ADHD in childhood and adolescence.

Method: We did a nationwide, register-based cohort study of the sex ratio in siblings of the 16,381 patients in Denmark diagnosed with ADHD at age 17 years and younger and registered in the nationwide Danish Psychiatric Central Register between January 1, 1994 and May 28, 2013.

Diseases of the circulatory system among adult people diagnosed with infantile autism as children: A longitudinal case control study.

Background: Research dealing with adult people with autism spectrum disorders (ASD) noticeably lags behind studies of children and young individuals with ASD.

Aims: The objective of this study was to compare the prevalence and types of diseases of the circulatory system in a clinical sample of 118 adult people diagnosed with infantile autism (IA) as children with 336 sex and age matched controls from the general population.

Methods And Procedures: All participants were screened through the nationwide Danish National Hospital Register.

New Interview and Observation Measures of the Broader Autism Phenotype: Description of Strategy and Reliability Findings for the Interview Measures.

Clinical genetic studies confirm the broader autism phenotype (BAP) in some relatives of individuals with autism, but there are few standardized assessment measures. We developed three BAP measures (informant interview, self-report interview, and impression of interviewee observational scale) and describe the development strategy and findings from the interviews. International Molecular Genetic Study of Autism Consortium data were collected from families containing at least two individuals with autism.

The sex ratio of full and half siblings of people diagnosed with an autism spectrum disorder: a Danish Nationwide Register Study.

In the extreme male brain theory of autism sex steroid hormones are hypothesized to influence brain development and to mediate sex differences in developmental psychopathology. Within this scope we examined the sex ratio (proportion of males) in siblings of individuals diagnosed with autism spectrum disorders (ASD). We did a nationwide, register based cohort study of the sex ratio in 17,380 siblings of the 10,297 patients diagnosed with ASD at age 17 years and younger and registered in the nationwide Danish Psychiatric Central Register between 1994 and 2012.
