What is Parkinson’s disease?

Parkinson’s disease is a brain disorder that causes shaking, stiffness, and trouble with walking, balance, and coordination, according to the National Institutes of Health (NIH).

About half a million people in the United States are reported to be affected by Parkinson’s, but it’s possible that the numbers are much higher, according to NIH. 

The four main symptoms of Parkinson’s are:

  • Bradykinesia – slowness of movement
  • Postural instability – impaired balance
  • Rigidity – stiffness of the limbs and trunk
  • Tremor – trembling in the arms, hands, head, jaw, and legs

The symptoms of Parkinson’s typically start out gradually and get worse over time, according to the NIH. Severe symptoms can cause difficulty walking and talking, and possibly also sleep problems, depression, memory trouble, and fatigue.

It is the second most common neurodegenerative disease, after Alzheimer’s, and there is no cure, according to the NIH.
