Rasmussen syndrome is a form of childhood epilepsy that causes
frequent, severe seizures. The seizures damage one side (hemisphere) of the
brain, often resulting in gradual loss of movement and sensation on one side of
the body, problems with mental development, partial loss of vision in one eye,
and speech and language problems.
Children with Rasmussen syndrome usually develop seizures before
age 10. Infections such as meningitis and encephalitis may play some role in
causing the condition.
Drug therapy is almost never successful in treating Rasmussen
syndrome. For some children with the condition, though, a type of brain
surgery called hemispherectomy can prevent seizures and improve some of the
problems that may occur with the epilepsy.
