Wise, Elizabeth A.; Smith, Marcia D.; Rabins, Peter V. – Journal of Autism and Developmental Disorders, 2017
Little is known about Autism Spectrum Disorder (ASD) in persons over age 50. In a retrospective, naturalistic review of 74 individuals aged 30 and older meeting DSM-5 criteria for ASD, the point prevalence of behavioral and neuropsychiatric symptoms (BNPS) declined significantly for 12 of 13 BNPS over a mean of 25 years while many other features…

Uzun Cicek, Ayla; Sari, Seda Aybuke; Mercan Isik, Cansu – Journal of Mental Health Research in Intellectual Disabilities, 2020
Introduction: Intellectual disability (ID) is characterized by limitations in cognitive and adaptive functioning. The aim of this study is to examine sociodemographic characteristics, perinatal and childhood risk factors, and prevalence of psychiatric and biomedical comorbidities in children with ID. Methods: 260 patients with ID were included in…

Saqr, Youssra; Braun, Erika; Porter, Kyle; Barnette, Debra; Hanks, Christopher – Autism: The International Journal of Research and Practice, 2018
Little has been reported about how to improve health care access and delivery for adolescents and adults with autism spectrum disorder. To understand the contributions to the health disparities in the autism spectrum disorder population, we conducted two independent research approaches to learn about current medical needs. A retrospective chart…

Zablotsky, Benjamin; Black, Lindsey I. – National Center for Health Statistics, 2020
Objective: This report examines the prevalence of developmental disabilities among children in both rural and urban areas as well as service utilization among children with developmental issues in both areas. Methods: Data from the 2015-2018 National Health Interview Survey (NHIS) were used to examine the prevalence of 10 parent- or…

Croen, Lisa A.; Zerbo, Ousseny; Qian, Yinge; Massolo, Maria L.; Rich, Steve; Sidney, Stephen; Kripke, Clarissa – Autism: The International Journal of Research and Practice, 2015
Compared to the general pediatric population, children with autism have higher rates of co-occurring medical and psychiatric illnesses, yet very little is known about the general health status of adults with autism. The objective of this study was to describe the frequency of psychiatric and medical conditions among a large, diverse, insured…

Oguni, Hirokazu – Journal of Policy and Practice in Intellectual Disabilities, 2013
The co-occurrence of epilepsy in people with intellectual disabilities (ID) and other developmental disabilities (DD) has received attention because it has a significant negative impact on health, well-being, and quality of life. The current research investigating the frequency and form of epilepsy in children with ID and DD is reviewed, with…

Angkustsiri, Kathleen; Krakowiak, Paula; Moghaddam, Billur; Wardinsky, Terrance; Gardner, Jerald; Kalamkarian, Nareg; Hertz-Picciotto, Irva; Hansen, Robin L. – Autism: The International Journal of Research and Practice, 2011
Objective: There is clinical heterogeneity among the autism spectrum disorders (ASD). The presence of dysmorphology (minor physical anomalies; MPAs) is one possible tool for defining a clinically relevant subset in ASD. This study employs an adaptation of Miles and Hillman's (2000) classifications by using photographs to identify a subgroup with…

MacLean, William E.; Dornbush, Kylee – Journal of Mental Health Research in Intellectual Disabilities, 2012
Self-injurious behavior (SIB) is a devastating condition associated with intellectual and developmental disabilities (IDD). Efforts to understand its development are focused on early childhood when the behavior first emerges. Limited prevalence data on SIB during early childhood are currently available. The purpose of this study was to determine…

Matson, Johnny L.; Neal, Daniene – Research in Autism Spectrum Disorders, 2009
Autism spectrum disorders (ASD) are serious neurodevelopmental disorders which often co-occur with intellectual disabilities. A disorder which is strongly correlated with both of these disabilities are seizures and epilepsy. The purpose of this review was to provide an overview of available research on seizures and epilepsy in the ASD population…

Symons, Frank J.; Byiers, Breanne J.; Raspa, Melissa; Bishop, Ellen; Bailey, Donald B., Jr. – American Journal on Intellectual and Developmental Disabilities, 2010
We used National Fragile X Survey data in order to examine reported self-injurious behavior (SIB) to (a) generate lifetime and point prevalence estimates, (b) document detailed features of SIB (frequency, types, location, severity) in relation to gender, and (c) compare comorbid conditions between matched pairs (SIB vs. no SIB). Results indicate…

Smalley, Susan L.; And Others – Journal of Autism and Developmental Disorders, 1992
A literature review of autism and tuberous sclerosis complex (TSC) substantiates a significant association between the two. Studies of 14 autistic probands and 13 TSC probands identified 7 TSC subjects with autism, who had more seizures and mental retardation than those without autism. More male TSC probands with autism than female were…
