I'm not sure I want, or would be able to pay for, an autopsy, although one of the staff neurologists was interested enough to probably study, so I will check into it. His PCP said being bedbound would probably mean he'll survive 4-5 years. He has atonal and demylineating PN, caused by nutritional deficiencies following rapid (unplanned) weight loss (almost 200 pounds in less than 3 months..I blame personality change brought on by medication, mostly clonidine/catapres (spelling?)).
