Outlook

Parkinson's disease reduces the length of your life, but it is not fatal. It is a disease that progresses from a phase without symptoms to possibly a state of complete disability, sometimes within 10-20 years. As with all diseases, a spectrum of possibilities exists. The course a particular person will experience cannot be predicted. Certain patterns have been noted.

• PD has been characterized by some as either tremor predominant or postural instability and gait disturbed (PIGD).
  
  
  • Younger people usually have tremor as the main symptom, but progression of the disease is slower. They also seem to have more muscle control problems.
    
    
  • By contrast, older people experience more from PIGD. This can be a serious problem in this age group because of an increased fall risk.
  
  
• In addition to the physical problems with PD, a significant emotional price is paid as well.
  
  
  • Many people have profound depression and other thinking problems throughout the disease.
    
    
  • It is estimated that about 30% of people with PD experience altered mental status.
  
  
• Treatment is getting better at easing symptoms and may even slow progression of the disease. With continued research and clinical trials investigating new medications and surgical procedures, it is thought that one day we may be able to either prevent or cure PD.
