Imagine driving in your car and suddenly not recognizing where you, you don’t remember where you were going and have no idea how to find your way home. What if you looked across the breakfast table at your spouse and no longer recognizing them? Or maybe you have to brace yourself every time you visit your parent, waiting for the day when they won’t know who you are. This is reality for the estimated 50 million (worldwide) Alzheimer’s suffers and their families.
For a world with an aging population, Alzheimer’s is a growing problem. Recent estimates suggest that 11% of people over the age of 65 have Alzheimer’s disease. For people 85 and older, that number increases to 32% (1).
Alzheimer’s disease is a devastating degenerative brain disease. It is the most common cause of dementia, and is characterized by a decline in cognitive skills such as memory, language skills, communication and problem solving abilities. These symptoms make it difficult for people with Alzheimer’s to perform everyday activities. It also is difficult to diagnose, even more difficult to treat, and, as of now, impossible to cure.

A week ago Sunday, I walked among crowds of mothers, grandmothers, and children of all ages celebrating Mother’s Day at the Botanical Gardens in St. Louis, Missouri. As I watched happy families, I couldn’t help being jealous. Though I was there with my grandmother and other close relatives, I missed my mom, especially since I was in my hometown for her funeral the day before. Had my mom been alive and well, we might have walked those same paths ourselves and enjoyed the new life teeming above the earth. Instead, my mother lost her battle of more than six years with Lewy Body dementia the week before at the age of 61.
As a biologist, I was well-aware of Alzheimer disease in the abstract, and tau proteins, beta-amyloid, and genetic predisposition. But until my mom was diagnosed in 2008, I was painfully ignorant of dementias other than Alzheimer disease. Once we knew what mom was fighting, I learned that Alzheimer disease and Lewy Body are hardly unique. The number of other dementias that exist is long and includes vascular dementia, mixed dementia, Parkinson’s disease, frontotemporal dementia, Creutzfeldt-Jakob disease, Huntington disease, and many others.Continue reading “Lessons From the ‘Long Goodbye’”
Forgetting. Forgetting your address; your spouse; your children; your friends; your life. It is something that none of us want to think about, but it hangs over some of us like a specter. Can’t remember if you fed the cat? Where you put your car keys? Did you forget to pack your lunch or return a phone call? Maybe you are trying to do too many things at once, or maybe you are tired. There are lots of perfectly normal reasons why we all forget things from time to time, but every time I forget something there is a nagging voice in my head saying, “Maybe it is something else.” Continue reading “Remembering Not to Forget”
