The literature from inception to 2020 on the prevalence of epilepsy in autistic individuals was systematically reviewed and further explored by subgroup analyses and meta-regression models. This systematic review is registered with PROSPERO (CRD42020179725). A total of 66 studies from 53 articles were included. The updated pooled prevalence of…

Although epilepsy commonly presents with autism in children, it is currently unknown whether established estimates represent the prevalence and incidence of epilepsy in autistic adults. Our objective was to use population-level Medicaid data to determine prevalence, incidence, and antiepileptic drug use associated with epilepsy in a unique…

The prevalence of autism spectrum disorder in South Africa is unknown and, to date, very little research has been performed within school systems that could inform the rates, distribution and profile of needs of children with autism spectrum disorder in education. We performed a comprehensive database search of all children with autism spectrum…

Background: The aim of this paper was to summarize the main results of the POMONA-ESP project, the first study to explore health status in a large representative, randomized and stratified sample of people with intellectual developmental disorders in Spain. Methods: The POMONA-ESP project collected information about the health of 953 individuals…

Autistic children have a high prevalence of co-occurring mental health, developmental/behavioral, and medical conditions, but research on sex/gender differences has been mixed. We used Florida healthcare claims data to characterize sex differences (female/male) in co-occurring conditions among autistic children ages 1-21 (N = 83,500). After…

Epilepsy is reported to co-occur in individuals with autism spectrum disorder (ASD). Previous studies across the world have found prevalence estimates ranging from 4 to 38%. We examined parent-reported prevalence of co-occurring epilepsy and ASD in the most recent U.S. National Survey of Children's Health, 2011-2012. All analyses accounted for…

The objective is to examine the prevalence and health-care costs associated with asthma, epilepsy, hypertension, food allergies, and diabetes in children aged 0-18 years. Prevalence was calculated using 2005-2012 Medical Expenditure Panel Survey (MEPS) data, a population-based, nationally representative sample. Using MEPS, two-part models…

Background: People with intellectual disability (ID) and epilepsy are more likely to die prematurely than the general population. A significant number of deaths in people with epilepsy may be potentially preventable through better seizure control, regular monitoring and raising awareness among patients and carers. The aim of this project was to…

The purpose of this study was to examine the prevalence of falls and risk factors for falls in 1,515 adults (greater than or equal to 18 years) with intellectual disability using baseline data from the Longitudinal Health and Intellectual Disability Study. Nearly 25% of adults from the study were reported to have had one or more falls in the past…

The current study investigated comorbidity in eighty-nine children and adolescents with Autism Spectrum Disorder in Ireland. Comorbidity is the presence of one or more disorders in addition to a primary disorder. The prevalence of comorbid psychological disorders, behaviours associated with comorbid psychopathology, epilepsy, gastrointestinal…

The aim of this study was to describe the health status profile and identify the healthcare needs of adults with intellectual disability (ID) residing in 18 of Hong Kong's residential care facilities. The author employed a cross-sectional study using a structured questionnaire survey to collect data on 811 persons with ID (432 males, 53.3%, and…

Aim: To estimate the prevalence of cerebral palsy (CP) and the frequency of co-occurring developmental disabilities (DDs), gross motor function (GMF), and walking ability using the largest surveillance DD database in the US. Methods: We conducted population-based surveillance of 8-year-old children in 2006 (N = 142,338), in areas of Alabama,…

The purpose of this study was to examine the occurrence of epilepsy in children with intellectual disability. An additional goal was to determine if there were statistical differences in the occurrence of epilepsy related to the sex, level and etiology of intellectual disability of children. The sample consisted of 167 children with intellectual…

Aim: To establish any differences between patients with and without a diagnosis of personality disorders, being treated in a secure inpatient service for offenders with intellectual disability (ID) in the UK. Method: A cohort study involving a selected population of people with ID and offending behaviours. Results: The study included a total of…

This study compared mortality among Danish citizens with autism spectrum disorders (ASDs) with that of the general population. A clinical cohort of 341 Danish individuals with variants of ASD, previously followed over the period 1960-93, now on average 43 years of age, were updated with respect to mortality and causes of death. Standardized…
