This week, I read the book so you don’t have to. Here are my take-aways:
Dr. Dale Bredesen is a leading advocate of a comprehensive approach to treating symptoms of dementia. The book The End of Alzheimer’s Program is an update of his 2017 publication The End of Alzheimer’s: The First Program to Prevent and Reverse Cognitive Decline and includes lessons learned from 8 years of treating patients with the protocols he developed.
He rejects the notion of a single cause of Alzheimer’s and other dementias in favor of a holistic approach that focuses on the things your brain needs to function and the things that get in the way of its doing so. The program seeks to protect your brain and ward off cognitive decline by using diet and behavioral changes to support its essential activities while minimizing toxins that impair its ability to function properly.
He argues that the effort to find a drug that eliminates beta amyloid, for example, is misguided. You have to ask “How did it get there in the first place?” It turns out that beta amyloid is produced as part of the brain’s immune system to combat toxic invaders. So a remedy that is available to you right now is to identify the toxins (both chemical and biological, like rogue microbes that escape from you intestines and break through the blood-brain barrier) that are affecting you and eliminate them. Once you’ve done that, your brain’s immune response will not be triggered as often and you will not produce as much amyloid. It turns out you can manage a lot of this through diet.
Moreover, your brain has a natural way of removing beta amyloid after it has been created. It happens when you sleep. Therefore getting 7-9 hours of sleep each night can help ward off cognitive decline.
Bottom line: to a great extent, you can determine your own cognitive future by adopting a brain healthy diet and adding behavioral elements like exercise, sleep hygiene, stress management, cognitive challenge and social interactions.
He makes his case with meticulously documented references to the existing and emerging body of research and supplements it with case studies of people who were able to reverse their cognitive decline using his program. At times, it reads like an episode of “Grey’s Anatomy” or “House” where the doctors are unable to cure the illness until someone discovers that a rare toxin is causing the symptoms. They eliminate the toxin and the patient recovers.
As it pertains to dementia, the idea that you can reverse symptoms is pretty radical and flies directly in the face of the old notion that dementia is an unavoidable part of aging. As Dr. Bredesen documents, though, there are a large number of dementias that can be traced back to chemical, environmental or behavioral causes that can be rectified.
Which brings us to his program. It begins with an extensive battery of tests to identify the pathogens that might be affecting you as well as determining your levels of good chemicals and compounds. Once these factors are identified, you can design a diet that will correct imbalances and eliminate neurotoxins at their source. Progress is documented through ongoing testing and tweaks are made as you chart your reactions to the changes you have implemented.
Most of the book is spent going into great detail about how your diet affects long-term brain function. I’ll admit, I glazed over at the extended paragraphs laden with scientific terminology describing the chemical compounds and intra-cellular functions that were involved. Although he says he intends the book for consumers, it seems his real audience is physicians who he hopes will adopt his program. I can see how the book would be a great resource for someone who is guiding you through the process, but it definitely contains way too much information for most of us. Nonetheless, there are plenty of general recommendations and steps you can take to get started.
The chapters on exercise, sleep, stress management and cognitive challenge are informative, brief and a lot more digestible than the diet section!
Finally, Dr. Bredesen emphasizes that dementia is a process that takes years to develop. Your brain does its best to ward off attackers and to clean up the detritus after each daily battle. Over time, though, debris piles up and at some point the accumulation begins to take a toll on your cognitive functioning.
The good news is that most of this seems to be reversible if you start working on it soon enough.
