Memory loss is NOT always a sign of Alzheimer’s and CAN be REVERSED. As many as HALF of older people diagnosed as senile may have nerve damage caused by vitamin B-12 deficiency, a deficiency that can be CURED with B-12 supplements. The Annals of Pharmacotherapy reports that taking ANTACIDS can ALSO reduce B-12 absorption. Many doctors say don’t IGNORE a senility diagnosis, get your B-12 levels checked … and get a second opinion.
