Parkinson’s is a neurologic disease that robs people of control over their movements. It typically starts with tremors, and is characterized by slow movement, a shuffling gait, stiff limbs, balance problems and slurred speech.

Who gets it? About 1 million Americans are living with Parkinson’s, and 10 million people worldwide, the foundation estimates. It usually appears after age 60, although sometimes it can develop before age 50. What causes it? The exact cause isn’t known but Parkinson’s develops when cells that produce one of the brain’s chemical messengers, called dopamine, begin to deteriorate and die.

Dopamine transports signals to parts of the brain that control movement. Parkinson’s symptoms appear after enough dopamine-producing cells die that there.
