Ic. Gillberg et al., AUTISTIC BEHAVIOR AND ATTENTION DEFICITS IN TUBEROUS SCLEROSIS - A POPULATION-BASED STUDY, Developmental Medicine and Child Neurology, 36(1), 1994, pp. 50-56
In a population-based sample of 28 individuals under the age of 20 yea
rs, autistic symptoms were present in 24 and DSM-III-R autistic disord
er in 17. Many of the children and adolescents diagnosed as autistic a
lso showed attention deficit/hyperactivity. There was no specific asso
ciation between autistic behaviour and the presence of infantile spasm
s. Some of the children with tuberous sclerosis and autism were of nea
r-normal intelligence. Indirectly, the results suggest that as many as
9 per cent of all children with autism may have tuberous sclerosis.
