Because there are such a wide variety of autism types and spectrums, it can be difficult to group a child's symptoms together. Here's a look at 6 main types and very basic markers. If you're concerned that your child may be autistic, be sure to speak with your doctor and express any concerns you might have -- he'll be able to help you and your child assess the best course of action and find the support and education you need.Autism or Autistic Disorder
What It Is: A collection of developmental disorders in which a child engages in repetitive behaviors and has trouble communicating and connecting with others. It's usually diagnosed around age 2 or 3, although some signs show up earlier.
Symptoms can be mild to severe.Regressive Autistic Spectrum Disorder
What It Is: Like autism, except that a child appears to develop normally until 18 to 24 months, then starts to regress. It occurs in about 20 to 30 percent of children with autism spectrum disorders.Pervasive Developmental Disorder -- Not Otherwise Specified
What It Is: A child has a few autistic traits but doesn't meet the full criteria for an autism diagnosis.Asperger's Syndrome
What It Is: A milder form of autism, usually diagnosed between ages 2 and 6, in which a child has good language skills and average to above-average intelligence but is socially awkward and engages in odd, repetitive behaviors.Childhood Disintegrative Disorder (CDD)
