What are Movement Disorders?
These can be described as problems moving too much (involuntary movements) or too little (slowness, stiffness like in Parkinson’s disease). Involuntary movements include:
- Tics (Tourette’s syndrome)
- Chorea (as in Huntington’s disease)
- Athetosis (often a form of cerebral palsy)
- Stereotypies (often associated with autism)
- Restless legs syndrome
Like Parkinson’s disease, there are related conditions that can cause the same reduction in movements (parkinsonism), such as vascular parkinsonism, multiple system atrophy and others. Movement disorders are due to disturbances of deep brain structures, called the basal ganglia. Accurate diagnosis by an experienced specialist is critical for movement disorders and most can be successfully treated.
