When Meryl Comer’s husband, Dr. Harvey Gralnick, chief of hematology and oncology at the National Institutes of Health, began forgetting routine things and demonstrating abrupt changes in behavior, doctors were confounded as to what was wrong. Diagnoses ranged from stress and depression to Lyme disease, from pernicious anemia to mad cow’s disease supposedly acquired from a trip to London. Finally, after years of inconclusive tests, he was diagnosed with Alzheimer’s, a seemingly impossible disease for a man in his prime.\n\nComer gave up her television career and for the next two decades cared for Harvey in their home, tending to his every need while watching him regress into an emotionally distant and sometimes violent stranger. \
