The word “autism” has its origin in the Greek word “autos,” which means “self.” Children with ASD are often self-absorbed and seem to exist in a private world in which they have limited ability to successfully communicate and interact with others. The Centers for Disease Control and Prevention (CDC) estimates that about 1 in every 54 children in the U.S. It is four times more common among boys than among girls. Who is affected by ASD?ĪSD affects people of every race, ethnic group, and socioeconomic background.
Many children show symptoms by 12 months to 18 months of age or earlier. The behavioral signs of ASD often appear early in development. The symptoms and their severity can change over time. People with ASD share some symptoms, such as difficulties with social interaction, but there are differences in when the symptoms start, how severe they are, the number of symptoms, and whether other problems are present. The term “spectrum” refers to the wide range of symptoms, skills, and levels of impairment that people with ASD can have.ĪSD affects people in different ways and can range from mild to severe.
