How is Ohtahara syndrome treated?

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