I-123 Brain Studies of Serotonin Metabolism in Psychiatric Patients and Normal Volunteers Clinical Trials Information presented on Clinical Trials Search isn't intended to be a substitute for proven healthcare advice, trips or treatment using a real physician. We are not docs. Always confer with your mD on I-123 Brain Studies of Serotonin Metabolism in Psychiatric Patients and Normal Volunteers conditions. Clinical Trials Search.org is a site dedicated to listing clinical research studies in human subjects. I-123 Brain Studies of Serotonin Metabolism in Psychiatric Patients and Normal Volunteers Clinical research trials and I-123 Brain Studies of Serotonin Metabolism in Psychiatric Patients and Normal Volunteers medical trials take place in hundreds of localities across the U.S.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually measure the effectiveness of new drugs. The intention of the studies / projects is to resolve certain human health questions. Clinical trials are a popular means for physicians, government agencies, and private sector corporations to detect remedies for all forms of circumstances, like I-123 Brain Studies of Serotonin Metabolism in Psychiatric Patients and Normal Volunteers. I-123 Brain Studies of Serotonin Metabolism in Psychiatric Patients and Normal Volunteers Clinical Trials and other clinical trials allow for volunteers to undergo healthcare treatment options before they are available to the masses. Most times the participants receive treatment for free, and every now and again they are paid for their time. Occasionally there is a cost for a I-123 Brain Studies of Serotonin Metabolism in Psychiatric Patients and Normal Volunteers clinical trial. Subjects typically recieve the finest healthcare available for their I-123 Brain Studies of Serotonin Metabolism in Psychiatric Patients and Normal Volunteers condition. Hazards are a reality, nonetheless, and might include more or frequent mD trips, health risks (potentially life-endangering), and/or the treatment being ineffective. Trials are federally regulated with stern guidelines to protect clinical trials subjects.

I-123 Brain Studies of Serotonin Metabolism in Psychiatric Patients and Normal Volunteers
For Condition: Healthy,Mental Disorder,Obsessive Compulsive Disorder,Schizophrenia,Tourette Syndrome
Status: Completed
Sponsor(s): National Institute of Mental Health (NIMH) ,
Synopsis: Abnormalities in the re-uptake of dopamine and serotonin have been described in various neuropsychiatric disorders and substance abuse. [I-123] Beta-CIT is a recently developed radioligand for SPECT imaging of dopamine and serotonin transporters. [I-123]Beta-CIT SPECT has been used at the SPECT-lab of the Clinical Brain Disorders Branch in over fifty subjects without adverse events. Due to the trace concentrations used, a pharmacological effect of Beta-CIT is unlikely and has not been observed. The purpose of this study is to use Beta-CIT and SPECT to study the expression of dopamine and serotonin transporters in vivo in normal controls and various patient populations to address hypothesized abnormalities of the transporters in different disorders and to understand the effects of genetic variations in the genes of these transporters on their in vivo expression.
