Research Initiative for Functional Movement Disorders (FMD)

FMD is part of a larger spectrum of neurologic conditions called functional neurologic disorder. People with FMD can experience a large variety of different symptoms and abnormal movements. The movements are involuntary and can look like shaking (tremor), weakness, abnormal postures of the limbs or the body (dystonia), jerks (myoclonus), walking and balance problems and tic-like movements. Often times, there can be a mix of different functional movements. The movements can happen all the time or just sometimes.Many times, people with FMD can experience other symptoms as well. Those can be fatigue, dizziness, troubles concentrating, pain and many others.
