Gelastic Seizure

Gelastic Seizure

Hypothalamic Hamartoma (HH) is a malformation in the brain. It is usually diagnosed at birth or in childhood. One of the effects of HH may be Gelastic or “laughing” seizures.

Infants or small children with this type of seizure laugh uncontrollably, with sounds or facial expressions that indicate fear or anxiety – not happiness or merriment. As the child gets older, the frequency of the seizures can increase. They may interfere with normal activities, such as going to school or forming friendships.

Treatment for Gelastic Seizures, and for HH in general, may include anti-epilepsy drugs or occasionally surgery.
