Yes, like me, people are uninformed and only knew about the tremors. Then I started watching a friend from church once a week for an hour or two while his wife went to a staff meeting. He had advanced Parkinson disease, and was having a very tough time with lots of symptoms. That was my educational experience with the disease. He passed away a couple of years ago.
Now, I was diagnosed with Parkinson disease about 6 months ago. It was like a severe kick in the gut. I'm doing well, and learn more about what helps me, and what doesn't help.
