Does anyone here know about Parkinson's?

My grandma was diagnosed with Parkinson's today. I don't know a lot about it. I googled a little, but I don't know if that is going to make it sound worse than it is or not. I think that it is probably in the early stages. Her arm and leg shake but, she says she can control that sometimes. I don't know all of the symptoms to know if she has any others. Also, she still has to get a MRI to see where/how much of her brain it is affecting. The doctor gave her some medication to take everyday to try to control it.
She is almost 80. I know that it is more likely to get Parkinson's as you age.
I guess I just want to kind of know what to expect with all of this since it is just starting.
