If you're new to Parkinson's I would just suggest you take your time learning about it. I was diagnosed 2016 and found myself looking up too much too fast. I frightened myself half to death!
There's a lot of depressing and misinformation out there. But there's also a lot if help,advice and new people to meet. This website is a good place to start
PD varies greatly from person to person, so what works for one person does not necessarily work for all. It's all trial and error.
Once you get used to the shock of diagnosis life goes on, differently, but it goes on.
Good luck, Daffy
