Epilepsy may develop even though you don't have any risk factors for it. A cause can't always be found. This is especially true in many forms of childhood epilepsy.
Children and older adults are most likely to have epilepsy. But it can start at any age. It's possible that epilepsy may run in families. But you don't have to have a family history to develop epilepsy.
Epileptic seizures occur when abnormal bursts of electricity in the brain briefly upset normal brain function. It's not always clear what triggers the bursts of abnormal electrical activity.
Tumors, scar tissue from an injury or disease, or abnormal brain development may damage a specific area of the brain and cause partial seizures. But you may not have any of these conditions and still have epilepsy.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
