This is a good time for you to re-evaluate those activities you may have assumed were no longer possible -- employment, volunteer work, & social activities,, such as card playing, sports, & the like.  The harder you work to maintain your normal routine & activities, the less likely your PD will dominate your life.

True, you may need to make some adjustments in physical activities to accommodate your PD.  For example,  you may find that sports requiring more lateral (side-to-side) movement, such as golf & ping pong, are easier  for you.  Or,  if you were a marathon runner,  think about  race-walking or just plain walking.  One PWP, Parky, biked over 42,000  miles in a 10 year period by switching to a recumbent three-wheel trike.

His motto :"let's take the PARK out of Parkinson's"

The point is that you do have choices & you can take charge instead of allowing assumptions to dictate your routine.  Work with your doctor & other members of  your professional health team to determine the right physical activities for you
