|Brief Title ICMJE||Study of Specimens Obtained During Epilepsy Surgery|
|Official Title ICMJE||Research Study of Specimens Obtained During Epilepsy Surgery|
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.
This is a protocol to perform research studies on tissues that are removed in the operating room during surgical procedures for medically intractable epilepsy. Our aim is to acquire and supply useful tissue specimens for intramural NIH research projects.
The investigators will be free to select which patients will undergo surgery. However, the total number of patients that can be enrolled in the protocol will be restricted. This protocol is not designed to test any new treatments. Any treatment under this protocol will be based on the current standard of care for epilepsy surgery. The goal of the surgical procedure is to remove the epileptic focus. Standard procedures to be performed are 1) anterior temporal lobectomy or 2) amygdalohippocampectomy for temporal lobe epilepsy, and 3) focal cortical resection for epilepsy that arises outside the temporal lobe. These are the research aspects of the protocol: 1) Any brain tissue that is removed and is not required for diagnostic studies will be used for laboratory studies, consistent with institutional guidelines. 2) Meningeal samples, dura only, will be taken to examine for tissue markers of lymphatic vessels. 3) Blood tests to test for immune and inflammatory mediators will be performed. 4) Saliva will be collected to test for immune and inflammatory markers.
Participants in this protocol will be evaluated for potential eligibility for other NINDS clinical trials as they are developed. However, they will not be required to enter any protocol and their decision to participate will be entirely voluntary. No more than 120 patients will be accepted in this protocol.
