From the Denver Post:
Doctors and specialists spent two years testing Rae Ann Schmaltz, initially believing she had multiple sclerosis but later looking for anything, including tropical diseases and Lou Gehrig's disease. She endured endless poking and prodding, including 160 blood tests, urine tests, MRIs, even spinal taps. All were negative.

Doctors now believe Schmaltz suffers from a copper deficiency caused by an abundance of zinc found in the Poligrip she used to secure her dentures.
