Autism spectrum
Autism spectrum disorder is a developmental disorder in which a child's communication and social skills are affected. Children with autism spectrum disorder can experience a loss of their previously acquired language and social skills. This is often reported by the child's parents. Children can experience loss of vocabulary and language understanding, as well as no longer make eye contact or play social and imitative games when they previously had. They can also experience a loss of motor and basic skills like toileting or feeding themselves. In autism spectrum disorder, this regression occurs in the first few years of development.
