Epilepsy—or rather epilepsies, since the term actually encompasses several diseases—is the most common chronic neurological disease after migraine. It affects just under 1% of the population.
Epilepsy and its treatments
Epilepsy manifests itself through seizures, whose frequency and nature can vary considerably. It affects patients of all ages and may occur spontaneously or result from an illness or an accident.
Effective medicines are available to treat epilepsy, but in a significant minority of patients—approximately 35%—these treatments, even when taken as prescribed, do not completely eliminate the seizures. This is referred to as refractory epilepsy.
