SYNGAP1-related ID is a genetic condition characterised by global developmental delay and epilepsy. Individuals with SYNGAP1-related ID also commonly show differences in attention and social communication/interaction and frequently receive additional diagnoses of Autism Spectrum Disorder (ASD) or Attention Deficit Hyperactivity Disorder (ADHD). We…

This study aimed to describe the behavioral profile of individuals with SYNGAP1-ID. Parents/carers of 30 individuals aged 3-18 years old with a diagnosis of SYNGAP1-ID and 21 typically developing individuals completed the Vineland-3 Adaptive Behavior Scale and the Child Behavior Checklist. We found that those with SYNGAP1-ID showed fewer adaptive…

This systematic review aimed to identify factors significantly associated with the occurrence of epilepsy in autistic individuals and to consider the impact of study quality on findings. Electronic databases were systematically searched on October 2nd, 2020 and records retrieved were limited to those published from 2000 onwards. Study quality was…

This is a retrospective case series of pediatric patients referred to the psychogenic nonepileptic events clinic (PNEE) who had comorbid diagnoses of autism spectrum disorder (ASD) or intellectual disability (ID). We describe 15 patients, nine with ASD and six with ID who had a telephone visit follow-up at 12 months. There were higher rates of…

Background: People with epilepsy and intellectual disability should be considered at high risk of developing metabolic bone disease. Risk is increased with number of comorbidities and polypharmacy, particularly anti-seizure medications. One way of improving bone health is to ensure that every one has adequate levels of vitamin D through…

The clinical similarity among different neuropsychiatric disorders (NPDs) suggested a shared genetic basis. We catalogued 23,109 coding de novo mutations (DNMs) from 6511 patients with autism spectrum disorder (ASD), 4,293 undiagnosed developmental disorder (UDD), 933 epileptic encephalopathy (EE), 1022 intellectual disability (ID), 1094…

Background: This study explored antiepileptic drug use, frequency of seizures, and the effect of psychotropic drugs with the potential to lower the seizure threshold in persons diagnosed with epilepsy and intellectual disability. Methods: Data for this study were drawn from Wave 3 of the Intellectual Disability Supplement to the Irish Longitudinal…

CDKL5 deficiency disorder (CDD) results in early-onset epilepsy and lifelong cognitive and motor impairments. With no validated measure for communication in CDD, this study evaluated the psychometric properties of the Communication and Symbolic Behavior Scales-Developmental Profile Infant Toddler Checklist (CSBS-DP ITC). Caregivers (n = 150;…

Background: Children and adolescents with cerebral palsy (CP) commonly have behaviour problems. The present study aimed to determine which of the most common clinical features experienced by children and adolescents with CP and intellectual disability are associated with behaviour problems. Method: We investigated 11 possible associated variables…

The prevalence of autism spectrum disorder in the world has increased over the last decade, but the prevalence, incidence, and characteristics of autism spectrum disorder in China were not well understood. Using administrative data, we aimed to estimate the prevalence and incidence of autism spectrum disorder and describe the co-occurring…

Background: People with epilepsy (PWE) have a higher fracture risk than nonepilepsy populations. Antiepileptic drugs (AEDs) cause bone loss. Limited physical activity and poor dietary intake increase fracture risk in PWE. People with an intellectual disability have higher prevalence of epilepsy, likely to be on multiple AEDs, with poorer response,…

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…

Aerophagia is a functional gastrointestinal disorder characterized by excessive swallowing of air associated with abdominal distension and pain, flatulence, belching, nausea, and vomiting. The purpose of the current study was to evaluate the effectiveness of an antecedent-based behavioral intervention on aerophagia with an adolescent female…

Background: Reliable and valid screening instruments for depression and anxiety are needed for adults with intellectual disabilities. Methods: Internal consistency (n = 198), inter-rater reliability (n = 41), test-retest reliability (n = 37) and criterion validity (n = 43) were studied in adults aged between 18 and 49 years. Internal consistency…

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…
