I am 68 and have had PD 3 yrs. Per my neurologist I am still in the early stages. I take a lot of Sinemet and other medicines. By about 2 yrs after my initial diagnosis I was having difficulty climbing stairs some of the time depending on the Parkinson's. One night I had to sit on my bottom & push up the stairs. My husband was willing to invest in a a motorized stair lift chair. I convinced him to sell our house & we now live in a 1 story house. We have 1st floor laundry. We had to ramp our front door. I seldom take the stairs to the basement. It was a hard decision. Good luck.
