I've spent 18 years as an Alzheimer’s caregiver and the last four as an activist. This certainly was not my plan. My 81-year-old dad began to show symptoms of dementia in 1994, the same year that former President Ronald Reagan published his now famous letter to the American people announcing his diagnosis of Alzheimer's disease. Three years later in 1997, at age 57, my husband Richard was diagnosed with mild cognitive impairment (MCI). MCI is a clinical diagnosis and an interesting term, but it is far from mild.
