Autism spectrum disorder and attention deficit/hyperactivity disorder are neurodevelopmental disorders with high rates of co-occurrence. However, there is a dearth of large, nationally representative studies examining the prevalence of co-occurring autism spectrum disorder and attention deficit/hyperactivity disorder among children. The aim of…

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…

Introduction: Families have a significant role in the lives of people with intellectual disabilities and challenging behaviors.

Parents of children on the autism spectrum are important members of their child's early intervention team, yet there are multiple barriers to translating evidence-based parent-mediated interventions in Mexico. We examined early intervention needs in the Mexican population and compared these needs to those of the Latinx Spanish-speaking population…

Autistic individuals may be at risk of premature mortality, and physical health comorbidity increases this risk; however, most studies fail to include older autistic adults or consider lifestyle-related factors that affect health. We developed an anonymous, online physical health survey. The final sample included n = 2368 individuals (mean age =…

Autism spectrum disorder in China differs considerably from autism spectrum disorder in the West in terms of prevalence estimates, education opportunities, and life outcomes of autistic people. The lack of autism spectrum disorder awareness could be a key factor underlying the disparities. To date, there has been no evaluation of autism spectrum…

Working memory (WM) limitations are frequently reported for children with specific learning disorder (SLD). However, WM capacity influences more than literacy and numeracy, as research highlights the contribution of WM to language development, in particular syntax. In this article, the authors study the effect of syntactic intervention, i.e.…

The UK prevalence of parent-reported autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD) were estimated from the Millennium Cohort Study. Case definition was if a doctor or health care professional had ever told parents that their child had ASD and/or ADHD. Data were collected in 2008/2009 for 14,043 children. 1.7%…
