OBJECTIVES
To evaluate the efficacy of the Positron Emission Tomography (PET)-fluorodeoxyglucose (FDG-18) modality in combination with neuropsychological techniques to assess cerebral function abnormalities in subjects with Alcohol Dementia (AlcD) and Korsakoff's syndrome (KS). The current trial is aimed at defining brain regions which show impaired function in these subjects.
METHODOLOGY
Subjects are offered water before their study begins. A catheter will be placed in a vein in one arm and another will be placed in an artery or vein of the hand on the other arm. The venous catheter will be used to inject the radiotracer and the arterial (or other venous) catheter will be used to collect blood samples to verify the rate at which the radiotracer is cleared from the blood. After a half-hour uptake phase, subjects are asked to empty their bladder to keep the radiation exposure to the bladder as low as possible. Subjects are then positioned in the PET scanner, where the technician provides blankets and padding in order to make them as comfortable as possible. Subjects may not move during the scan, which may last 60 to 120 minutes. Subsequently, the subjects may be placed in a magnetic resonance imaging (MRI) scanner for 2 scans.
IONIZING RADIATION, RADIOACTIVE SUBSTANCES, OR CHEMICAL SUBSTANCES
Fluorine-18 Fluorodeoxyglucose
INVOLVEMENT OF AND RISKS TO HUMAN SUBJECTS
PET scan risk includes: venous catheter (bruising, faintness, blood clot [1%]); arterial catheter (bruising, pain, faintness); radiation (equivalent to back x-ray). If an arterial catheter is to be placed, lidocaine is used to provide local anesthesia before placing the catheter.
MRI scan risk includes: discomfort associated with lying still in an enclosed space.
