Autism is a disorder where children have very minimal speech and social interaction, are involved in repetitive motions, and have the inability to socialize. There are different degrees of it, from very mild cases to severe cases that need a lot of help with their daily activities. Early indicators include a little bit of a socialization problem and the inability to socialize. Developmental screening is done as early as 15 to 18 months of age to identify those kids that are not reaching their milestones.
