So far my smell and balance are fine. I do have random bouts of bad-but-brief vertigo, but I've had those for decades. I won't list the myriad of odd symptoms I experience on a daily basis--but they're all things I've been experiencing since I was a teenager. Perhaps that's a good sign that they're not PD-related. Hard to say.

The only movement-related thing I've noticed is something I've had my entire life: body parts randomly jerking. So, for example, an arm or leg might suddenly jerk, or my jaw will snap shut. But, I've had these things ever since I was a teenager, and doctors never seemed concerned.

I've relayed all this (and other symptoms) to the neurologist, so she's aware. I've also been telling doctors about all these other symptoms for decades, but none have seemed concerned nor investigated them.
