Is anyone disappointed with their neurologist who just seems to want to prescribe meds or replace meds with more meds?

The meds will always be a juggling act with a patient having Parkinson's.
What I was impressed about with our 80 y.o. neighbor, who was courageous in fighting this disease, who kept walking daily in his walker, was that he kept rallying.
When everyone thought this was the end, so sad, this man would be out walking down the street, recovered and rallying. So encouraging to see.

Please read about Parkinson's on this forum. I recommend this expert:

No, our neurologist does not prescribe meds any more. Actually only two were ever prescribed and neither did anything to help. The neurologists only monitors her decline and advise me on what care might work.
She reviews all of her other current meds and note to our PCP her opinion on what should be continued or discontinued. Since the meds are for other problems/conditions, nothing has been recommended to be discontinued.

I got very frustrated with the geriatric psychiatrist. That is why we put our mom in a geriatric behavioral health facility for a week to get a much more advanced and thorough DX. We got it. 67k. Medicare and her supplement paid for all of it.

Welcome to the wonderful world of medicine. That's how it works. Doctor hears symptoms and based on rote learning, prescribes a set of meds. If that works, great. If not, move on to the next set of meds. Repeat until it works or until the list of meds is exhausted and give up.

Medicine is not deterministic. Each patient is an experiment.
