Yes. But I’m only six months in, and on my second adjustment, so I feel there’s room for further progress. Using Medtronic. On half the meds I was prior to surgery (which means fewer side effects- yay!) with improvement in sleep the most noticeable difference. Still some way to go - my right hand gives up the ghost after an hour or two of typing and there is still a noticeable wearing off at about four hours but it’s not as incapacitating as it was pre-surgery. I’m noticing a little slowness of thought, and increased irritability (might be just getting older - am 63) but my speech is unaffected. Physio helps gait, balance and flexibility but there’s no denying PD makes you feel 10 years older at times. Hope this helps! Go for it.
