Epilepsy is a chronic neurological disorder that causes patients to have recurrent seizures. Developmental and epileptic encephalopathies—or DEEs – are seizure disorders that are often treatment resistant. They most often begin in infancy and are associated with seizures of long duration and major developmental delays. These conditions—which include Lennox-Gastaut syndrome, Dravet syndrome, tuberous sclerosis complex, and others—are both rare, and challenging to diagnose and treat effectively. Staying current with the latest information on DEEs, their treatments, and the potential role for novel and emerging therapies, is essential to help maintain low seizure activity and achieve the best patient outcomes for these patients.

On this site we invite you to explore more about the pathophysiology and assessment of DEEs, as well as treatment strategies. We have also provided patient support strategies with additional reading and resources to further your knowledge in this area. We invite you to explore our high-definition animations, apps, and other tools to further enhance your knowledge.
