I have been very frustrated with all this. I have lots more symptoms that fit my adrenal tumor than fit Parkinson's. I don't have balance problems unless you count I could never walk a rail or tightrope. I do a lot of normal walking with a long stride and ride a bike. I work with my hands every day maintaining my older vehicles and farm equipment. Not a soft voice. The neurologists Nurse Practitioner Insisted I start Carb/Lev and Selegiline. I really cannot say whether anything has changed. There are advantages to loss of smell, I was sprayed by a skunk last week. The smell didn't bother me like it did everyone else. I am concerned I might be getting treatment for a wrong diagnosis. It certainly wouldn't be the first time. Had I not gotten another opinion three times I probably would have assumed room temperature long ago.
