title: Seizures and intellectual disability associated with tuberous sclerosis complex in the west of Scotland.
abstract: Of 104 individuals with tuberous sclerosis complex ascertained from the total population of the west of Scotland, 52 were born before and 52 after 1st July 1966. Of those born before. 10 had no seizures, 14 had seizures and no intellectual disability and 28 had seizures and intellectual disability; of those born after, four had no seizures, 18 had seizures and 30 had seizures and a degree of intellectual disability. Infantile spasms or other generalised seizures as the presenting seizure type (N = 29) was strongly associated with intellectual disability; partial seizures as the presenting seizure type (N = 19) was associated with normal development. Although the onset of seizures under one year of age and the presence of multiple seizure types were associated with intellectual disability, the strongest association was with the type of presenting seizure.
