Official title
HHV6B in Epilepsy Imaging and CSF Studies
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will look for evidence that a virus called HHV-6B may be related to seizures and to a form of brain injury called mesial temporal sclerosis that is associated with seizures. The study will use new, more sensitive brain scans to try to detect brain regions that might be affected by the virus and will examine cerebrospinal fluid (CSF, the fluid that bathes the brain and spinal cord) for evidence of the virus as well. Healthy volunteers and people with seizures uncontrolled by anti-epileptic drugs who are between 18 and 45 years of age may be eligible for this study. Candidates are screened with a physical examination and laboratory tests. Participants undergo the following procedures: * PET scan. This test uses a radioactive chemical called 18FDG, which is detected by the PET scanner to obtain images of the brain. The subject lies on a table with his or her head positioned in the scanner. A swimming cap with a small light reflector is placed on the head to monitor the position of the head during the scan. A catheter (plastic tube) is inserted into an artery at the wrist or elbow crease of the arm for obtaining blood samples during the scan, and a second catheter is placed in a vein in the other arm for injecting the 18FDG. The scan takes up to 2 hours. A second scan may be done over an additional 15 minutes. * MRI. This test uses a strong magnetic field and radio waves to obtain images of the brain. The subject lies on a table that can slide in and out of a metal cylinder surrounded by a magnetic field. Most scans last between 45 and 90 minutes. * Lumbar puncture. The subject sits upright or lies on a table with the knees curled to the chest for this procedure. A local anesthetic is injected to numb the skin and a needle is inserted in the space between the bones in the lower back where the CSF circulates below the spinal cord. A small amount of fluid is collected through the needle. * Blood tests. About 4 tablespoons of blood are drawn for viral tests.
