Genetic and Environmental Predisposing Factors of Autism Spectrum Disorders

Abstract

Autism spectrum disorder (ASD) is a complex neurodevelopmental situation with persistent difficulties in social interaction, speech, nonverbal communication and repetitive behavior that can be diagnosed at an early age. In recent years, the increasing number of ASD cases has shifted the interest of science in this direction. According to a worldwide survey, one in every 59 children has autism spectrum disorder. In this article, environmental and genetic factors that cause autism spectrum disorders are discussed.
