Autism Spectrum Disorder (ASD) is a serious Neuro-Developmental Disorder that impairs a child's ability to communicate and interact with others. Autism significantly affects verbal and non-verbal communication and social interaction that adversely affects the child’s educational performance. It may also cause restricted repetitive behaviors, interests and activities.
The term "Spectrum" in autism spectrum disorder refers to the wide range of symptoms and severity.
Autism can affect boys four to five times more than girls.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) is the 2013 update to the American Psychiatric Association's (APA) classification and diagnostic tool. In the United States the DSM serves as a universal authority for psychiatric diagnosis. Treatment recommendations, as well as payment by health care providers, are often determined by DSM classifications, so the appearance of a new version has significant practical importance.
The DSM-5 redefined the autism spectrum to encompass the previous (DSM-IV-TR) diagnoses of autism, Asperger syndrome, pervasive developmental disorder not otherwise specified (PDD-NOS), and childhood disintegrative disorder.
Features of these disorders include social deficits and communication difficulties, stereotyped or repetitive behaviors and interests, sensory issues, and in some cases, cognitive delays. (Wikipedia)
