Movement Disorders
Movement disorders are a group of neurologic conditions that cause either increased, involuntary movement or decreased, slow voluntary movement.
Overview
Movement disorders are neurologic conditions that cause problems with movement, including:
- Increased movement that can be voluntary (intentional) or involuntary (unintended)
- Decreased or slow voluntary movement
Common Types
There are many different movement disorders. Some of the more common types include:
- Ataxia: The loss of muscle coordination.
- Dystonia: A condition in which involuntary contractions of your muscles cause twisting and repetitive movements, which can be painful.
- Huntington's disease: An inherited disease that causes nerve cells in certain parts of the brain, including those that help control voluntary movement, to waste away.
- Parkinson's disease: A disorder that slowly worsens over time, causing tremors, slowness of movement, and trouble walking.
- Tourette syndrome: A condition that causes people to make sudden twitches, movements, or sounds (tics).
- Tremor and essential tremor: Conditions that cause involuntary trembling or shaking movements in one or more parts of your body.
Causes
Causes of movement disorders include:
- Genetics
- Infections
- Medicines
- Damage to the brain, spinal cord, or peripheral nerves
- Metabolic disorders
- Stroke and vascular diseases
- Toxins
Treatment & Management
Treatment varies by disorder. While medicines can cure some disorders and others improve when an underlying disease is treated, there is often no cure. In such cases, the goal of treatment is to improve symptoms and relieve pain.
