Alzheimer’s Researchers Shift Focus After Failures

July 7, 2019

The title of this post is identical to the title of a front page article by Christopher Rowland in the 4 July 2019 issue of the Washington Post. These researchers are shifting their focus to new drug treatments that deal with other factors than the defining features for an Alzheimer’s diagnose, which are amyloid plaque and neurofibrillary tangles. The conclusion that this research is fruitless was made by a former researcher in this area. The Myth of Alzheimer’s is a book by Peter J. Whitehouse, M.D. and Ph.D and Daniel George, M.Sc. Whitehouse is the former researcher who came to the conclusion that this research would never yield results. There was a healthy memory post on this book in 2011. HM believes Dr. Whitehouse is working on non drug treatments for Alzheimer’s. The Alzheimer’s association provides little, if any, support in this area. The Alzheimer’s association provides financial support for drug research. HM wonders in the unlikely event that a useful drug was produced, whether the Alzheimer’s Association had some agreement to limit costs or would this company be allowed to prey on the public. Before giving any money to the Alzheimer’s association, potential donors should demand an answer to this question.

There have been many posts on this topic including one titled “The Myth of Alzheimer’s.” Perhaps the most significant finding is one that is rarely, if ever, mentioned. And that is that people die with the defining characteristics for an Alzheimer’s diagnosis, the amyloid plaque and neurofibrillary tangles, but who never knew that they had the disease because they never had any behavioral or cognitive symptoms of the disease. The explanation offered is that these people had developed a cognitive reserve as a result of being cognitively active during their lifetimes.

The reappearing theme in this blog is that people should live cognitively fulfilling lives with growth mindsets in which they are continuing to learn. This involves System 2 processing, more commonly referred to as thinking. Our normal processing mode is System 1, which is quite fast and efficient. Here we are in cruise control where the conscious content just keeps flowing. As one proceeds through life this becomes easier and easier. Much has been learned, there is little interest in learning anything new, so the mind effectively is on cruise control. Cognitive neuroscience has termed this the default mode network, which is quite similar, if not identical, to Kahneman’s System 2 processing which is from cognitive psychology.

HM knows people who have been cognitively active throughout their lives, yet still succumbed to Alzheimer’s or dementia. But there are other causes. One of HM’s friends trained himself to get by on 4 hours of sleep per night. Research shows us that 7 to 8 hours of sleep are required. Other ambitious people burn the candle and both ends, which also leads to sleep deprivation.

HM wishes the researchers well in their research. But everyone should know that by engaging in a cognitively challenging life with growth mindsets they should greatly decrease, if not eliminate, the prospect of dementia or Alzheimer’s. Of course, a healthy lifestyle is also assumed.
