Other Movement Disorders

  • Ataxia
    Ataxia is a symptom—not a disorder. It refers to a failure of muscle control in the arms and legs, resulting in a lack of balance, coordination, and possibly a disturbance in gait.
  • Dystonia
    Dystonia is a disorder that affects the way the body moves. It causes the muscles to contract, which makes them move involuntarily or get stuck in an abnormal position.
  • Essential Tremor
    Essential tremor is a neurological disorder that causes the hands, head, trunk, voice, or legs to shake rhythmically. It is often confused with Parkinson’s disease or dystonia.
  • Huntington’s Disease
    Huntington’s disease is a brain disorder in which brain cells, or neurons, in certain areas of the brain start to break down. As the neurons degenerate, the disease can lead to emotional disturbances, loss of intellectual abilities, and uncontrolled movements.
  • Progressive Supranuclear Palsy
    Progressive supranuclear palsy (PSP) is a complex condition that affects the brain.
  • Tourette's Disorder
    A person with Tourette's disorder develops multiple repeated tics. The tics are abrupt, purposeless, and involuntary vocal sounds or muscular jerks.
