Is Lennox-Gastaut syndrome inherited ?
Most cases of Lennox-Gastaut syndrome are sporadic, which means they occur in people with no history of the disorder in their family. However, 3 to 30 percent of people with this condition have a family history of some type of epilepsy. People with the cryptogenic form of Lennox-Gastaut syndrome are more likely than people with the symptomatic form to have a family history of epilepsy.
