About Parkinson's

Related Conditions

Some other brain diseases and movement disorders share symptoms with Parkinson's disease. While each condition is unique, they also share treatment options, and research into one may help understand and treat others.

Conditions Related to Parkinson's Disease

  • Dyskinesia

    Dyskinesia is uncontrolled, involuntary movement that can look like fidgeting or wriggling. In Parkinson's, dyskinesia can happen with long-term levodopa use and longer time with disease. Many new therapies are working to prevent or treat this complication.

  • Dystonia

    Dystonia is painful muscle contractions that lead to abnormal postures. A symptom of Parkinson's and a movement disorder, dystonia affects about 500,000 people in the United States and Canada. Researchers are working to better understand and treat this condition.

Atypical Parkinsonisms

  • Lewy Body Dementia

    People with Lewy body dementia (LBD) have the motor symptoms of Parkinson's but develop dementia (significant memory and/or thinking changes). Since Parkinson's and LBD share underlying biological changes, research into one may help treat the other.

  • Multiple System Atrophy

    This brain disease causes slowness, stiffness and walking problems, but people with multiple system atrophy also have more problems with the body's automatic functions (blood pressure, digestion). They also can have other symptoms, such as difficulty controlling emotions.

  • Corticobasal Degeneration

    This brain disease causes movement, memory or thinking, and behavioral problems. Corticobasal degeneration (CBD) involves a build-up of a protein called tau. Scientists are working to measure and target tau with new treatments to stop CBD and other tau diseases.

  • Progressive Supranuclear Palsy

    Progressive supranuclear palsy (PSP) is another disease linked to a build-up of the tau protein. It causes movement symptoms, eye movement problems, and memory and thinking (cognitive) changes. Research into tau could help diagnose and treat PSP.
