AUTISM
Autism is a neurological or brain disorder that profoundly affects a person’s ability tocommunicate, form relationships with others, and respond appropriately to the
environment. Those affected by autism fall along a spectrum of “high-functioning”
individuals to individuals who lack any means of communicating with others. The
prevalence of autism in the population is not well described. It was once thought that
autism was relatively rare, occurring in 4-5 per 10,000 persons. More recent estima-
tions put the prevalence of autism at 10-12 per 10,000 persons. A clear cause has not
been identified, although there is evidence for genetic predisposition. Autism is more
common in males and is more common in certain medical conditions.
