Myoclonus. This condition causes lightning-quick jerks of a muscle.
Parkinson's disease. This slowly progressive disease causes tremor, muscle stiffness, slow or decreased movement, or imbalance. It may also cause other symptoms not related to movement such as reduced sense of smell, constipation, acting out dreams and a decline in cognition.
Parkinsonism. Parkinsonism is a general term for slowness of movement along with stiffness, tremor or loss of balance. There are many different causes. Parkinson's disease and certain dopamine blocking medications are the most common causes. Other causes include degenerative disorders such as multiple system atrophy and progressive supranuclear palsy. Stroke or repeated head trauma also can cause parkinsonism.
Progressive supranuclear palsy. This is a rare neurological disorder that causes problems with walking, balance and eye movements. It sometimes may resemble Parkinson's disease but is a distinct condition.
Restless legs syndrome. This movement disorder causes unpleasant feelings in the legs while relaxing or lying down, often relieved by movement.
Tardive dyskinesia. This neurological condition is caused by long-term use of certain drugs used to treat psychiatric conditions, called neuroleptic drugs. Tardive dyskinesia causes repetitive and involuntary movements such as grimacing, eye blinking and other movements.
Tourette syndrome. This is a neurological condition that starts between childhood and teenage years and is associated with repetitive movements and vocal sounds.
Tremor. This movement disorder causes rhythmic shaking of parts of the body, such as the hands, head or other body parts. The most common type is essential tremor.
Wilson's disease. This is a rare, inherited disorder that causes excessive amounts of copper to build up in the body, causing neurological problems, dystonia, tremor, parkinsonism or ataxia.(reference:mayoclin doc )
