Autism spectrum disorder includes conditions previously called autism, pervasive developmental disorder, and Asperger's syndrome. The causes are not known.
What Are the Types of Autism?
Over time, psychiatrists have developed a systematic way of describing autism and related conditions. All of these conditions are placed within a group of conditions called Autism Spectrum Disorders. Depending on how severe symptoms are, they are classified under level 1, 2 or 3. Pervasive Development Disorder was used as a term before but now is no longer used.
How Is Autism Treated?
Treatments for autism vary depending on the needs of the individual. In general, treatments fall into four categories:
Behavioral and communication therapy
Medical and dietary therapy
Occupational and physical therapy
How Do Medical and Dietary Therapies Treat Autism?
The goal of medication is to make it easier for the person with autism to participate in activities such as learning and behavioral therapy. Drugs used to treat anxiety, attention problems, depression, hyperactivity, and impulsivity may be recommended.
