This study was carried out to evaluate the rate of progression in Parkinson's Disease. What was analysed was the time taken to progress from one stage of the Hoehn and Yahr scale to the next.
The Hoen and Yahr characterises patients according to a scale of five stages of severity, from Stage 1, which is mild, to Stage 5, which is incapacitated. For the questionnaire go to the Hoehn and Yahr scale.

The average time taken to progress from Stage 1 (mild) to Stage 2 (mild but various symptoms) was 1 year 8 months.  The average time taken to progress from Stage 2 to Stage 3 (typical) was 7 years and 3 months.  From Stage 3 to Stage 4 (severe) took 2 years. From Stage 4 to Stage 5 (incapacitated) took 2 years and 2 months. So the stage with typical symptoms lasts the longest. Those factors associated with faster progression were older age at diagnosis, and longer disease duration. Gender and ethnicity were not associated with the rate of Parkinson's Disease progression.

These figures are only averages. Progression is not inevitable. Some people with Parkinson's Disease have either : stayed the same for decades, reduced their symptoms, rid their symptoms, or worsened at a rapid rate.  For more current news go to Parkinson's Disease News.
