The Future of Preventive Brain Medicine: Breaking Down the Cognition & Alzheimer’s Disease Alphabet Soup
Posted By Dr. Dharma Singh Khalsa @ Alzheimer's Research & Prevention Foundation On January 3, 2012 @ 2:21 In Health & Wellness | Comments Disabled
As the president and medical director of the Alzheimer’s Research and Prevention Foundation (ARPF), it’s my job to stay on top of advances in the field of Alzheimer’s research. Recently, a number of articles in the medical literature have caught my attention. They are focused on a particular question that concerns most Baby Boomers like me: “Is memory loss just a normal part of aging?”
Many of my patients in their fifties, sixties, and older notice that they occasionally forget things like a name, face, or where they put their keys. They wonder whether this behavior is normal, or if it is a sign of Alzheimer’s disease. It’s a reasonable worry: Alzheimer’s disease is reaching epidemic proportions and recent surveys by the Alzheimer’s Association and others reveal that it is the Baby Boomers’ biggest health fear .
The answer to that question used to be, “Yes, we all experience some memory loss as we age. Don’t worry—it’s not Alzheimer’s.” Indeed, it was once thought that a little memory loss was an expected and accepted part of the normal aging process. There was even a term for it: Age-Associated Memory Impairment (AAMI).  It included a general slowing of mental functions such as processing, storing, and recalling new information. It also included a general decline in the ability to perform tasks related to cognitive function such as memory, concentration, and focus.
But here’s the rub: AAMI was never a clinical diagnosis, even though many physicians, lay people—and, yes, even yours truly—thought otherwise. Instead, AAMI is a technical diagnosis. It’s made by a psychometric test, not by actual clinical symptoms.
These days, we have a number of other, more accurate acronyms to describe the varying states of memory loss—a whole bowl of Alzheimer’s-related alphabet soup, if you will. And, unlike AAMI, these labels are based on real clinical diagnoses. They include:
That’s a lot of letters—but these new labels aren’t what I want you to take away from this proverbial soup bowl. The real issue here is not just a name change; it’s a shift in the way we think about memory loss and aging. Indeed, these alphabet diagnoses are not simply static states of memory impairment. A growing body of research suggests that they are instead points on a continuum of memory loss that often ends with a diagnosis of the dreaded Alzheimer’s disease. Unless properly treated—in my view, with an integrative medical program—memory loss tends to get worse over time. In my experience, with integrative treatment, memory loss can be improved and people’s functionality can be preserved for a much longer time.
But is any memory loss “normal”? I recently asked that same question of Barry Reisberg, M.D., Professor of Psychiatry and Director of The Aging and Research Center at New York University. Dr. Reisberg is one of the world’s leading experts on the subject of memory loss and has studied it for decades. His answer: “Memory loss may be normative (average), but that doesn’t mean it’s normal. The real question is what is progressive over time.”
And that brings us back to our alphabet soup. In one landmark study , Dr. Reisberg and his colleagues looked at 260 people, 60 of whom had NCI and 200 of whom had SCI. After 7 years, they discovered that memory declined in 7 people with NCI (15%) and 90 with SCI (54.2%). Of the people with NCI, 5 developed MCI and 2 developed probable Alzheimer’s. On the other hand, of the 90 people with SCI who progressed, 71 developed MCI and 19 declined all the way to Alzheimer’s.
What this means is that SCI appears to progress to MCI and even to Alzheimer’s disease. Subjective or not, even minor memory problems—the kind that many of us typically attribute to just “getting older”—are not normal and should be taken seriously. Consider these statistics, also from Dr. Reisberg:
Numbers like these not only drive home the serious news that no memory loss is a normal part of aging, but they also make it clear that we’re on the cusp of what many experts believe will be an epidemic of Alzheimer’s disease as Baby Boomers continue to age.
I’ve shared information on ARPF’s website  about the integrative medical approach to prevent and reverse memory loss. But the fact is that protecting against memory loss isn’t just an individual’s responsibility. They say it takes a village to raise a child. Well, it takes a village to support the fight against Alzheimer’s disease—and the types of memory loss that precede it—too.
To that end, in late November, U.S. Representatives Ed Markey and Chris Smith, co-chairs and co-founders of the Bipartisan Congressional Taskforce on Alzheimer’s Disease, outlined their recommendations for the National Alzheimer’s Plan, a strategy proposed for President Obama’s administration to tackle the disease. I heartily agree with many of their suggestions , which include:
Memory loss isn’t like gray hair or wrinkles. Contrary to what many of us used to believe, it is not a normal sign of aging. In my opinion, that’s all the more reason to make Alzheimer’s disease—and the whole bowl of “alphabet soup”—a thing of the past by prioritizing prevention treatment today. Beyond that, we clearly need to move past a “magic bullet” drug approach mentality.
There is a lot we can do right now to live a brain healthy lifestyle and sharing that work with society is where I’d like to see our focus in the future.
