Study of Specimens Obtained during Epilepsy Surgery Clinical Trials Resources presented on Clinical Trials Search is not meant to be a substitute for proven health advice, calls or treatment with a real medical. We aren't mDs. Always consult your doctor on Study of Specimens Obtained during Epilepsy Surgery conditions. Clinical Trials Search.org is a website dedicated to listing clinical research studies in human subjects. Study of Specimens Obtained during Epilepsy Surgery Clinical research trials and Study of Specimens Obtained during Epilepsy Surgery healthcare trials take place in a lot of of localities throughout the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials typically assess the effectiveness of new does drugs. The function of the studies / projects is to figure out specific human medical questions. Clinical trials are a popular means for doctors, government agencies, and private sector corporations to find cures for all varieties of conditions, like Study of Specimens Obtained during Epilepsy Surgery. Study of Specimens Obtained during Epilepsy Surgery Clinical Trials and other clinical trials allow volunteers to access health treatment options before they are available to the masses. Many times the subjects receive professional assistance for free, and every now and again they are compensated for their time. Sometimes there is a cost for a Study of Specimens Obtained during Epilepsy Surgery clinical trial. Human subjects often obtain the finest healthcare possible for their Study of Specimens Obtained during Epilepsy Surgery condition. Hazards are a reality, nevertheless, and might include additional or frequent dr. calls, health hazards (potentially life-jeopardizing), and/or the treatment being uneffective. Trials are federally regulated with stern guidelines to protect clinical trials patients.

Study of Specimens Obtained during Epilepsy Surgery
For Condition: Epilepsy
Status: Recruiting
Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) ,
Synopsis: 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.
Details: 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 hypothesis is that we can qcquire 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) A biopsy of the superficial temporal artery will be taken in the course of the surgical procedure. 3) Blood tests to test for immune and inflammatory mediators will be performed. 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 30 patients will be accepted in this protocol.
Eligibility:
