I was diagnosed at 93. I had many symptoms for years but attributed all to old age. I went to a neurologist when legs and balance caused me to fall and he diagnosed spinal stenosis and leg tests were done. When my body totally collapsed I ended in hospital I was diagnosed. I’m now in assisted living for a year and for my duration and have had 3 instances where my body/legs have collapsed on trying to get into bed. The only thing to do is sleep then on waking up you are back to your “now” normal. Droopy eyelids, fatigue , hands barely working, no balance and total weakness are it. I now take 9 daily meds vs only 3 that I took for years. I’m thankful that this awlful disease didn’t surface in my younger years.
