A brain disorder, thought to be a genetic disorder, that only affects girls. Symptoms usually occur when the child is 12–18 months old. Acquired skills, such as walking and communication skills, disappear and the girl becomes progressively handicapped, perhaps with signs of autism. There are repetitive writhing movements of the hands and limbs, and inappropriate outbursts of crying or laughter. There is no cure for Rett’s syndrome and sufferers need constant care and attention. Parents of an affected child should receive genetic counselling.
