Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: Dystonia is a movement disorder in which a person s muscles contract on their own. This causes different parts of the body to twist or turn. The cause of this movement is unknown. Researchers think it may have to do with a chemical called acetylcholine. They want to learn more about why acetylcholine in the brain doesn t work properly in people with dystonia. Objective: To better understand how certain parts of the brain take up acetylcholine in people with dystonia. Eligibility: Adults at least 18 years old who have DYT1 dystonia or cervical dystonia. Healthy adult volunteers. Design: Participants will be screened with a medical history, physical exam, and pregnancy test. Study visit 1: Participants will have a magnetic resonance imaging (MRI) scan of the brain. The MRI scanner is a metal cylinder in a strong magnetic field that takes pictures of the brain. Participants will lie on a table that slides in and out of the cylinder. Study visit 2: Participants will have a positron emission tomography (PET) scan. The PET scanner is shaped like a doughnut. Participants will lie on a bed that slides in and out of the scanner. A small amount of a radioactive chemical that can be detected by the PET scanner will be given through an IV line to measure how the brain takes up acetylcholine.
