question: mY HUSBAND IS 82 AND HAS A HORRIBLE BALANCE PROBLEM. One doctor says it is Parkinson s and also the beginning of Alzheimer s but he had a stroke last year and this marked the beginning of his problem. He falls, uses a cane but has progressed to a walker, and someone mentioned brain crystal exercises. Do you have any ideas on this? Could there be an answer for us? He is going to have a lumbar spine MRI on Tuesday, and has been diagnosed with peripheral neuropathy. Where can I get help?
