Featured Studies

Featured studies include only those currently recruiting participants. They are listed according to the date they were added to the ClinicalTrials.gov registry, with the most recent studies appearing first.

  • (18F)FCWAY and the Blood-Brain Barrier.
    Evaluation study. Background: - The blood-brain barrier helps protect the brain from infections and toxins in the blood stream. Ages 18-50. Location in Bethesda, MD.
  • Oxytocin and Arginine Vasopressin in Pain Relief.
    Evaluation study. Background: - Oxytocin, a substance produced mostly in the brain, plays a role in influencing social interactions and reactions to stress, and may be related to pain. Ages 18-55. Location in Bethesda, MD.
  • The Medical HOME Study.
    Interventional study. There is an urgent need to develop practical, sustainable approaches to improving medical care for persons treated in community mental health settings. Ages 18 and over. Location in Marietta, GA.
  • Defining the Brain Phenotype of Children With Williams Syndrome.
    Evaluation study. Background: - Little is known about how the brain changes during childhood and adolescence, how genes affect this process, or how the brains of people with Williams syndrome change during this period. Ages 5-17. Location in Bethesda, MD.
  • Top-Down Attentional Control of Visual-Processing.
    Evaluation study. Background: - Previous studies have shown that people with certain types of brain damage may have particular problems paying attention and processing things that they see. Ages 18 and over. Location in Bethesda, MD.
  • Testing a New Therapy for Trichotillomania.
    Interventional study. This study will test the effectiveness of a new behavioral therapy for adults with trichotillomania (compulsive hair pulling). Ages 18-65. Location in Milwaukee, WI.
  • Imaging Cannabinoid CB1 Receptors in Alcohol Dependence.
    Evaluation study. The cannabinoid type 1 (CB1) receptor is a protein found in the brain that is involved with the effects of marijuana; it may also play a role in the effects of alcohol dependence and withdrawal. Ages 18-65. Location in Bethesda, MD.
  • Mirror Therapy for Phantom Limb Pain.
    Evaluation study. This study, conducted at the National Institutes of Health (NIH) and at Walter Reed Army Medical Center (WRAMC), will explore the phenomenon of phantom limb pain (a continued feeling of pain in an amputated limb) and will use functional magnetic resonance imaging (fMRI) to investigate the effect of mirror therapy on phantom limb pain. Ages 18-75. Locations in Washington, DC; Bethesda, MD.
  • PET Imaging of Cannabinoid CB1 Receptors Using [11C]MePPEP.
    Interventional study. The purpose of this protocol is to measure brain CB1 receptors in the hope to better understand how they work, so that one day we can understand how the CB1 receptors are involved in psychiatric, neurological, and behavioral disorders. Ages 18-65. Location in Bethesda, MD.
  • PET Imaging of Brain mGluR5 Receptors Using [18F]SP203.
    Interventional study. The metabotropic glutamate subtype five (mGluR5) receptor is a protein found in the brain and is the target for the excitatory chemical messenger glutimate. Ages 18-65. Location in Bethesda, MD.
  • Protein Synthesis in the Brain of Patients With Fragile X Syndrome.
    Evaluation study. Biosynthesis of proteins is essential for growth and continued maintenance of the entire neuron including axons, dendrites, and synaptic terminals, and it is clearly one of the important biochemical processes underlying adaptive changes in the nervous system. Ages 18-24. Location in Bethesda, MD.
  • MRS Measurement of Glutamate and GABA Metabolism in Brain.
    Interventional study. This study will use magnetic resonance spectroscopy (MRS) to measure in the brain the transfer of [13]C as it is naturally metabolized from glucose to specific chemical transmitters. Ages 18-65. Location in Bethesda, MD.
  • PET Scanning in Parkinson's Disease.
    Evaluation study. This is an in vivo positron emission tomography (PET) study of regional cerebral dopamine neurochemistry and blood flow in normal volunteers, persons with Parkinson's disease (both familial and sporadic), and those with schizophrenia spectrum disorders. Ages 18 and over. Location in Bethesda, MD.
  • Studies of Blood Flow to the Brain During Thought.
    Evaluation study. The purpose of this study is to use brain imaging technology to measure changes in blood flow to areas in the brain as individuals perform intellectual tasks. Ages 18-65. Location in Bethesda, MD.
