Many people whose seizures do not respond to medication will respond to surgical treatment, relieving seizures completely or almost completely in one-half to two-thirds of patients who qualify for surgery. The tests and surgery performed as part of this treatment are not experimental, but researchers are interested in using the data collected as part of routine standard epilepsy care to better understand epilepsy and its treatment.\n\nObjectives:\n\n\\- To use surgery as a treatment for drug resistant epilepsy in children and adults.\n\nEligibility:\n\n\\- Children and adults at least 8 years of age who have simple or complex partial seizures (seizures that come from one area of the brain) that have not responded to medication, and who are willing to have brain surgery to treat their medically intractable epilepsy.\n\nDesign:\n\n* Participants will be screened with a medical history, physical examination, and neurological examination. Imaging studies, including magnetic resonance imaging and computer-assisted tomography (CT), may also be conducted as part of the screening. Participants who do not need surgery or whose epilepsy cannot be treated surgically will follow up with a primary care physician or neurologist and will not need to return to the National Institutes of Health for this study.\n* Prior to the surgery, participants will have the following procedures to provide information on the correct surgical approach.\n* Video electroencephalography monitoring to measure brain activity during normal activities within a 24-hour period. Three to four 15-minute breaks are allowed within this period.\n* Electrodes placed directly in the brain or on the surface of the brain to measure brain activities and determine the part of the brain that is responsible for the seizures (seizure focus).\n* Participants will have a surgical procedure at the site of their seizure focus. Brain lesions, abnormal blood vessels, tumors, infections, or other areas of brain abnormality will be either removed or treated in a way that will stop or help prevent the spread of seizures without affecting irreplaceable brain functions, such as the ability to speak, understand, move, feel, or see.\n* Participants will return for outpatient visits and brain imaging studies 2 months, 1 year, and 2 years after surgery.","Objective\n\nThis protocol is being performed to collect prospective data on patients who receive standard of care treatment for drug resistant epilepsy and to follow the natural history of patients receiving epilepsy surgery, to investigate neurophysiological correlates of human cognitive function, to provide invasive monitoring for patients with tumor related epilepsy. Any treatment under this protocol will be based on the current standard of care for epilepsy surgery.\n\nStudy Population\n\nPatients 8 years and older whose seizures are uncontrollable with medication may participate in this study as well as patients with tumor related epilepsy in whom invasive monitoring is indicated.\n\nStudy Design\n\nPatients will be screened by study neurologists to confirm their diagnosis of drug resistant epilepsy. Patients that do not have a confirmed diagnosis of drug resistant epilepsy will be offered further evaluation in protocol 18-N-0066, Investigating Epilepsy: Screening, Evaluation and Treatment. Patients confirmed to have drug resistant epilepsy will be offered standard invasive and non-invasive diagnostic and surgical procedures. Diagnostic invasive monitoring with intracranial electrodes for further localization of their seizure focus may be required. The ultimate goal is to surgically remove or modify the epileptic focus. Standard procedures to be performed are 1) anterior temporal lobectomy or 2) amygdalohippocampectomy for temporal lobe epilepsy, 3) focal cortical resection for epilepsy that arises outside the temporal lobe, 4) removal of brain lesions causing epilepsy, 5) multiple subpial transection, and 6) placement of neurostimulator devices. These procedures are all FDA approved standard of care for treatment of drug resistant epilepsy.\n\nIn patients in whom invasive monitoring is medically necessary, neurophysiologic activity during cognitive tasks will be captured from intracranial surface and depth electrodes. Analysis will focus on the role of neuronal firing and aggregate neural activity 1) during cognitive function, 2) in other states such as wakefulness and sleep, and 3) during periods of time surrounding seizure activity.\n\nDrug Resistant Epilepsy\n\nPatients with drug resistant epilepsy will be followed for three months after the surgical procedure and will receive standard neurological examinations and MRI evaluation of the brain. Participants in this protocol will be evaluated for potential eligibility for other NINDS clinical trials.\n\nTumor Related epilepsy\n\nPatients with tumor related epilepsy will be enrolled in this protocol because of clinical indications arising from participation in a separate protocol, 16-N-0041 Tumor Related Epilepsy. Patients will complete participation after the three-month post-op visit.\n\nOutcome Measures\n\nBy providing standard care treatment for patients with drug resistant epilepsy, this protocol allows for descriptive and\u002For correlational studies based on the data collected through clinical care of these patients including neurophysiological correlates of cognitive function and studies of tissue sample acquired during surgery.
