BACKGROUND The epidemiology of intellectual disability co-occurring with schizophrenia and other psychiatric illness is poorly understood. The separation of mental health from intellectual disability services has led to a serious underestimation of the prevalence of dual diagnosis, with clinicians ill-equipped to treat affected individuals. AIMS To(More)
BACKGROUND It is well recognized that genetic disease makes a significant contribution to childhood illness. Here, we present recent population data describing the impact of single gene and chromosomal disorders on hospital admissions of children and adolescents. METHODS Hospital admissions for patients aged 0-19 years between 2000 and 2006, with a single(More)
Despite the demands it places on individuals, families and the community, intellectual disability (ID) is a neglected area of public health. Accurate estimates of prevalence are sparse and range from 0.5 to 3.0%. The cause of the condition is unknown in at least 50% of cases. This paper describes the Intellectual Disability Exploring Answers (IDEA) database(More)
The objective of this study is to compare the time trend of reported diagnoses of autism spectrum disorder (ASD), hyperkinetic disorder, Tourette’s syndrome, and obsessive-compulsive disorder across four countries after standardizing the study period, diagnostic codes used to define the conditions and statistical analyses across countries. We use a(More)
AIM To investigate the relationship between functioning and post-school day occupation for young adults with Down syndrome. METHODS Families of young people with Down syndrome (n = 269) aged 15-30 years in 2009 were recruited from the population-based Down syndrome 'Needs Opinion Wishes' database in Western Australia. Questionnaires were mailed to(More)
The authors investigated the association between intrauterine growth and intellectual disability (ID). The appropriateness of intrauterine growth was assessed using percentage of optimal birth weight, a measure that accounts for gestational age, maternal height, parity, and infant sex. Using population-based record linkage, singleton Caucasian and(More)
BACKGROUND It is unclear whether the increase in autism over the past two decades is a real increase or due to changes in diagnosis and ascertainment of autism spectrum disorders (ASDs), which include autism, Asperger syndrome and pervasive developmental disorder not otherwise specified (PDD-NOS). The aim of this study was to examine the trends in ASD over(More)
OBJECTIVE Children with Down syndrome, the most common genetic cause of intellectual disability, are prone to multiple and varied health-related problems. This study describes patterns of hospitalisations for children and young people with Down syndrome in Western Australia. METHODS Birth records were linked to the Western Australian population-based(More)
BACKGROUND Research findings investigating the sociodemographics of autism spectrum disorder (ASD) have been inconsistent and rarely considered the presence of intellectual disability (ID). METHODS We used population data on Western Australian singletons born from 1984 to 1999 (n = 398,353) to examine the sociodemographic characteristics of children(More)
Summary highlighted the contribution of birth defects. Over this time there has also been an increasing number of terminations of pregnancy for fetal abnormality. However, the effect of these terminations on mortality rates in Australia has not yet been estimated. The Western Australian Birth Defects Registry (BDR) records all birth defects that are(More)
