A pervasive developmental disorder, autism affects information processing in multiple ways. Many people with autism have difficulties with social interactions and communication, sensory deficits, and poor motor coordination.
Asperger's syndrome colloquially refers to a high functioning form of autism. People with Asperger's often lack social skills and sometimes have problems with motor regulation. However, their language and cognitive skills are largely intact.
There is no one specific treatment for autism.
Early intervention with highly structured behavioral, cognitive, and communication therapies can sometimes dramatically help autistic children learn skills, but few are able to live independently as adults.
