How is Lennox-Gastaut syndrome diagnosed?

A diagnosis of LGS is made when multiple seizure types, a slow spike-and-wave EEG pattern, and cognitive impairment are present. Some patients are diagnosed with LGS and another genetic epilepsy.

How is Lennox-Gastaut syndrome treated?

Currently there is no cure for LGS. Patients are treated for their symptoms, not for the underlying cause of the disease. Seizure control is the primary goal for patients with LGS. There are currently companies investigating treatments for LGS and researchers analyzing patient data to better understand the condition and all potential causes so a cure may be found.
