Parkinsons Disease Home > Parkinson's Disease Information

A chronic condition, Parkinson's disease results when there is a deficiency of a certain chemical in the brain called dopamine. This loss of dopamine causes the movement problems characteristic of Parkinson's disease, such as:
  • Tremor
  • Stiffness in the limbs and trunk
  • Slow movement
  • A shuffling gait.
Parkinson's disease is progressive, meaning its symptoms grow worse over time. It is not contagious, nor is it usually inherited (it does not pass directly from one family member or generation to the next).
Although there is no known cure, several treatment options are available that can help alleviate many of the symptoms. These treatments include things like medications (such as levodopa), lifestyle changes, and surgery.
