Extract
Autism is a pervasive and life-long disorder that is characterised by profound deficits in communication and social understanding, together with ritualistic and obsessional behaviours and a general resistance to change. Although usually associated with additional cognitive impairments (approximately 50% of those affected have an IQ below 50) the condition can occur in individuals of all levels of ability, and around 20% of cases have an IQ within the normal range. Estimates of prevalence vary from 3.3 to 16.0 per 10 000 and rates may be even higher if children within the autistic wider spectrum are included (Wing, 1993, 1996). Understanding of causation is still limited, although genetic factors are now known to play a major role (Lord & Rutter, 1994).
