Epilepsy is one of the most common neurological disorders and is characterized by abnormal electrical activity in the brain that leads to seizures. It is the fourth most common neurological condition and affects more than 65 million people worldwide.

At least 3.4 million people in the U.S. are living with seizures, including 470,000 children.

Seizures are unpredictable and can vary in frequency, from less than one per year to several per day. Seizures can be:

  • Brief lapses of attention
  • Brief episodes of involuntary movement in part of the body
  • Prolonged convulsions of the entire body, referred to as generalized seizures

Rare Pediatric Epilepsy

Rare pediatric epilepsy affects fewer than 200,000 children in the U.S. and can differ in cause, seizure type and severity. These children are at higher risk of sudden unexpected death in epilepsy (SUDEP) and have few or limited treatment options.
