The Effect of Advanced Parental Age on Prevalence of Autism Spectrum Disorder

Abstract

Autism spectrum disorder (ASD) is characterized by varying deficits in social communication and social interactions, and/or restricted, repetitive patterns of behavior, interests, or activities. The origin of ASD has long been studied and speculated. There is an increased interest in the risks associated with development of ASD. In recent years, parental age has been studied as a possible contributing factor to the development of autism. Studies are investigating the link between maternal and paternal age and autism. Possible associations have been speculated to be increase gene mutations, genetics, high risk pregnancy and lifestyle. This literature to date indicates possible associated factors, but is not yet definitive. This literature review will discuss the results of several studies and the recommendations for future research.
