Can Alzheimer’s Be Cured?  P. Murali Doraiswamy discusses recent breakthroughs

P. Murali Doraiswamy is the head of biological psychiatry at Duke University and is a Senior Fellow at Duke’s Center for the Study of Aging. He’s also the co-author of The Alzheimer’s Action Plan, a guide for patients and family members struggling with the disease. Mind Matters editor Jonah Lehrer chats with Doraiswamy about recent advances in Alzheimer’s research and what people can do to prevent memory loss.

LEHRER: What do you think are the biggest public misconceptions of Alzheimer’s disease?

DORAISWAMY: The two biggest misconceptions are “It’s just aging” and “It’s untreatable, so we should just leave the person alone.”  Both of these misconceptions are remnants of an outdated view that hinders families from getting the best diagnosis and best care.  They were also one of the main reasons I wanted to write this book.

Although old age is the single biggest risk for dementia, Alzheimer’s is not a normal part of aging.  Just ask any family member who has cared for a loved one with Alzheimer’s and they will tell you how different the disease is from normal aging.  Alzheimer’s can strike people as young as their forties; there are some half a million individuals in the United States with early-onset dementia.  Recent research has pinpointed disruptions in specific memory networks in Alzheimer’s patients, such as those involving the posteromedial cortex and medial temporal lobe, that appear distinct from normal aging.
The larger point is that while Alzheimer’s is still incurable it’s not untreatable.  There are four FDA-approved medications available for treating Alzheimer symptoms and many others in clinical trials.  Strategies to enhance general brain and mental wellbeing can also help people with Alzheimer’s.  That’s why early detection is so important.

LEHRER: Given the rapid aging of the American population - by 2050, the Alzheimer’s Association estimates there will be a million new cases annually - what are the some preventative steps that people can take to prevent or delay the onset of the disease?

DORAISWAMY: Unfortunately, there isn’t yet a magic bullet for prevention.  You can pop the most expensive anti-aging pills, drink the best red wine, and play all the brain games that money can buy, and you still might get Alzheimer’s.  While higher education is clearly protective, even Nobel Laureates have been diagnosed with the disease, although it’s likely their education helped them stave off the symptoms for a little bit.
