Development, behaviour and seizures in 300 cases of tuberous sclerosis.
TSC plus severe ID usually means seizures, hyperactivity, and sleep problems all at once.
01Research in Context
What this study did
Doctors mailed surveys to families of 300 people with tuberous sclerosis (TSC). They asked about seizures, sleep, activity level, and social skills.
What they found
Most people with severe learning disabilities also had many seizures. The same group often showed hyperactivity, sleep trouble, and autistic-like behaviors.
How this fits with other research
Leung et al. (1998) later counted autism in a TSC clinic and found it in 1 out of 5 patients. This extends the 1993 picture by giving a clear rate.
Goodwin et al. (2012) used math to split ASD-plus-epilepsy into sub-groups. Their work refines the broad seizure-autism link that the 1993 survey first mapped.
Annaz et al. (2011) saw the same heavy sleep load, but in Williams syndrome. Both studies show genetic syndromes share tired nights.
Edwards et al. (2007) profiled teens in 52-week schools. Like the TSC cases, those students had severe ID, little speech, and serious behavior problems.
Why it matters
When you see TSC, expect a triple load: seizures, hyperactivity, and poor sleep. Screen all three areas at intake. Share the seizure-autism link with parents so they seek early help. Track sleep with a simple log; fixing nights can calm days.

03Original abstract
Three hundred cases of tuberous sclerosis were surveyed by postal questionnaire, including 240 cases with learning difficulties. People who have tuberous sclerosis and severe learning disabilities also have a higher frequency of epileptic seizures than people with learning difficulties from all causes. Pervasive developmental disorder and hyperactive behaviour are behavioural features of the disorder. Sleep problems and the level of vigilant care required because of seizures or behaviour have implications on the level of service needed to support people with tuberous sclerosis in the community.
