Protocol Number: 02-N-0014

Title:

Research Study of Specimens Obtained During Epilepsy Surgery

Number:

02-N-0014

Summary:

This study will collect brain tissue samples for research purposes from patients undergoing surgery to treat epilepsy. The standard surgical procedure for medically intractable epilepsy-i.e., epilepsy that cannot be controlled with medicine-requires removal of more brain tissue than is needed for diagnostic study. This extra tissue, which would otherwise be discarded, will be used for research purposes. In addition, a blood vessel in the scalp, called the superficial temporal artery, is also normally cut during surgery, and a piece of this vessel will be taken for research use.

Patients 4 years of age or older who undergo surgery for medically intractable epilepsy may be eligible for this study.

Brain tissue collected under this protocol will be used for studies of brain cells in other diseases and of serotonin receptors. Any remaining brain tissue will be frozen for use in future research. The superficial temporal artery will be used for comparison with carotid arteries (a neck artery that supplies the brain) from patients with blockage of this blood vessel.
