I was diagnosed with Parkinson's several years ago. At first, I slept as I always had, but lately, I can't stay asleep and don't feel rested.

I've noticed I cannot respond as fast to complex questions as I once did. I have more "tip of the tongue" experiences than ever. Are these symptoms of cognitive decline that go along with PD?

My spouse no longer wants me to drive, but I don't see any problems. What can I say when she starts nagging?
