Playing golf with Parkinson's Disease

Does anyone have and (positive) experience, advice or knowledge about playing golf with Parkinson's Disease?

I've always been a high handicapper since taking up the game at the age of fifty some fourteen years ago, but this year my golf performance has declined dramatically. This downturn has coincided with a diagnosis of Parkinson's which I was given at the start of the year; but I genuinely don't know if it is the Parkison's or the fear of Parkinson's which is most affecting my game.

I have no problems as yet 'staying the course', i.e walking the eighteen holes on my hilly downland course (Lewes). And I'm okay, if short, with my driver off the tee. But my swing with my mid irons is very unreliable and any 'touch' or 'feel' I might once have had in my short game has disappeared.

In recent weeks I've come very close to putting away my golf bag for good, but I'd really like to carry on a while longer, and my specialist is urging me to keep going as the exercise can only do me good.

Any tips, thoughts, expertise out there?

Thanks for your response, Brigitte, but I regret I don't speak German. I think I've caught the meaning of 'meine langen nicht meir', though.
