What Are the Symptoms of Parkinson's Disease?

Symptoms of Parkinson's disease often manifest as:

  • A resting tremor
  • Stiffness or rigidity
  • A slow shuffling gait
  • Slowness of movement (bradykinesia)
  • Impaired balance
  • A reduction in automatic movements, such as blinking, swallowing, arm swing and facial expression.

The cause of Parkinson's disease is unknown. However, several factors are thought to play a role in disease development. These include rural living, exposure to pesticides or toxins, drinking well water and genetics. Advanced age is also a risk factor for development of Parkinson's disease. The average age of onset is 60, but the disease starts at a younger age in some cases.
