PARKINSON’S DISEASE

Parkinson's disease (PD) is a chronic and progressive movement disorder, meaning that symptoms continue and worsen over time. Parkinson’s involves the malfunction and death of vital nerve cells in the brain, called neurons. Parkinson's primarily affects neurons in an area of the brain called the substantia nigra. Some of these dying neurons produce dopamine, a chemical that sends messages to the part of the brain that controls movement and coordination. As PD progresses, the amount of dopamine produced in the brain decreases, leaving a person unable to control movement normally.`

Other common symptoms:
  • Stiffness or slowing of movement
  • In early stages face may show little or no expression
  • No arms swing while walking
  • Speech may become soft or slurred
  • Disease may aggravate over time
  • Postural instability
