Tuberous sclerosis (TS) is a multi-system genetic condition causing tuber-like growths in the brain and frequently in other vital organs. The condition develops before birth and continues to do so during the person's lifetime. It occurs in about 1 in 7000 people.
TS, also known as epiloia, was first diagnosed by Desiré Magloire Bourneville, a French physician more than 100 years ago, but still remains poorly understood and is often misdiagnosed. Children are born with TS and it can have a devastating effect on them and their families.
Although there is no known cure for TS, the outlook continues to improve as medical advances are made in earlier diagnosis, improved treatment of seizures, help for the behavioural problems, laser for the skin problems and special education for those who need it.
