My husband had balance and falling issues. He is 72, avg. weight and in general his health is good. Well, it too 4 neurologist to get what we think is the right answer. The first said Parkinson's, second said rare genetic disease, third said he didn't know. The fourth said distal axonal neuropathy and to stop drinking, eat right & exercise. Well he followed the doctor's advice and feels great. My point is, sometimes you have to keep trying different doctors till you find the right one. I did a lot of research on the computer to guide us...good luck !
