PDF Summary:The End of Alzheimer's Program, by Dale E. Bredesen

Alzheimer's disease affects millions of people, yet many still view it as an inevitable consequence of aging. In The End of Alzheimer's Program, Dale E. Bredesen challenges this view by presenting Alzheimer's as a condition that can be prevented and even reversed through targeted interventions. He identifies five distinct types of Alzheimer's, each with different underlying causes ranging from inflammation and toxin exposure to nutrient deficiencies and vascular issues.

Bredesen introduces the ReCODE/Unjection protocol, a comprehensive approach that addresses the root causes of cognitive decline. This guide explores the biological mechanisms behind Alzheimer's, including how the brain's signaling processes can either build or break down synapses. You'll learn about the role of gut health in cognitive function, dietary strategies like the KetoFLEX 12/3 method, and practical steps for monitoring your metabolic health to support brain function.

Metabolic factors, such as infections and inflammation, are also able to add to the risk of Alzheimer's. Bredesen explains that chronic infections can trigger the immune system to produce amyloid, which is linked to Alzheimer's. Infections that have been linked to Alzheimer's include herpes viruses, bacteria from poor dental health, tick-borne diseases, and fungi like molds and yeasts. Chronic inflammation is another contributor to Alzheimer's risk. A primary driver of ongoing inflammation is intestinal permeability, which allows bacteria and food particles to enter the bloodstream. Other causes of inflammation include gum disease, long-term sinus infections, metabolic syndrome, and exposure to pollutants such as air pollution and mold.

To reduce inflammation, Bredesen says to pinpoint and eliminate the source. Then, you can use anti-inflammatory supplements like omega-3s, curcumin, ginger, and cinnamon. To address persistent infections, pinpoint the specific pathogen and bolster your immunity.

The Lancet Commission's Perspective on Alzheimer's Risk Factors

The 2020 Lancet Commission on dementia prevention, intervention, and care, led by Gill Livingston et al., offers a different perspective on the risk factors for Alzheimer's disease. The commission identified 12 modifiable risk factors that account for around 40% of worldwide dementias, which could theoretically be prevented or delayed. These factors include less education, high blood pressure, hearing impairment, smoking, obesity, depression, physical inactivity, diabetes, low social contact, excessive alcohol consumption, traumatic brain injury, and air pollution. The commission's report doesn't mention chronic infections or intestinal permeability as significant contributors to Alzheimer's risk. Instead, it emphasizes the importance of addressing these 12 factors through public health interventions and individual lifestyle changes to reduce the global burden of dementia.

Environmental Drivers of Dysregulation: Inflammagens and Dementogens

Bredesen also discusses how toxins and chemicals can negatively affect cognition. He notes that a variety of chemicals can hinder cognition, either directly or indirectly, and it’s fairly common for several chemicals to collaborate in this cognitive compromise.

(Shortform note: Bredesen doesn’t explain how several chemicals can “collaborate” to undermine cognition. One possibility is that the brain can handle a certain amount of toxins, but when it’s exposed to several chemicals at once, it can’t keep up with the detoxification and repair processes. This overload can lead to a buildup of toxins that damage brain cells and disrupt normal function.)

The ReCODE/Unjection Protocol: Interventions and Implementation

Next, we’ll discuss Bredesen’s ReCODE/Unjection framework and how you can use it to stop Alzheimer's from occurring and address it if it has.

The ReCODE/Unjection Framework: Remove, Strengthen, and Reconstruct

Removing Drivers of Dysregulation

Bredesen emphasizes the importance of gut health in avoiding the deterioration of cognitive abilities. The gut microbiome is involved in many contributors to cognitive deterioration, such as immune system attacks on the body, metabolic functions related to fat, inflammation, insulin sensitivity, gaining weight, how the body absorbs nutrients, amyloid production, brain chemistry, sleep, reaction to stress, and removing toxins. The gut and the brain are in constant communication, and the microbiome of a person who has Alzheimer's resembles that of a person with type 2 diabetes or obesity. Laboratory experiments have shown that changing the intestinal microbes in mice with Alzheimer’s can improve or worsen the problem, based on the resulting microbiota. Research indicates that probiotic treatment can lessen cognitive decline, inhibit inflammatory mediators, and restore normal protein processing.

(Shortform note: While Bredesen emphasizes the importance of gut health, some researchers have found that altering your gut microbiome can have negative effects. In a study, researchers found that taking probiotics after antibiotics can delay the recovery of the gut microbiome in some people. The scientists found that the probiotics colonized the gut of some people, but not others. In those who were colonized, the probiotics delayed the return of the normal gut microbiome. The researchers also found that the probiotics reduced the diversity of the gut microbiome. The researchers concluded that probiotics may not be beneficial for everyone and that more research is needed to understand the effects of probiotics on the gut microbiome.)

It triggers the SIRT1 pathway, a crucial pathway for longevity and preventing Alzheimer's. Restoring gut health and improving the microbiome has positive effects on inflammation, nutrient absorption, neurotransmitters, and insulin resistance. Additionally, Bredesen points out that the gut microbiome can be affected by cesarean birth, pressure, medication, drinking, low fiber intake, refined carbs, growing older, swelling, and parasites. Beneficial bacteria, microbiome nourishment, intestinal recovery, and stool transplants can help restore the gut microbiome. The intestinal microbiome also affects detoxification. Consuming prebiotics influences the microbiome's toxin elimination rate and transit duration. If the gut functions slowly, removing toxins will also be sluggish.

(Shortform note: While restoring the gut microbiome can have positive effects on detoxification, it's important to note that some methods, like stool transplants, can carry risks. In 2019, the FDA issued a warning after two patients developed serious infections from multidrug-resistant bacteria following fecal microbiota transplantation (FMT). One patient died as a result. The infections were traced back to the donor stool, which had not been properly screened for these resistant organisms. This incident highlights the potential dangers of FMT when proper safety protocols are not followed. While FMT can be a powerful tool for restoring gut health, it must be approached with caution and under strict medical supervision to minimize the risk of transmitting harmful pathogens.)

Certain harmful substances, including antimicrobial agents, agricultural chemicals, plasticizers, toxic metals, and various medications, can also change the microbiome. Gut microbes might generate amyloids, which can affect the creation, breakdown, and clearance of our own beta-amyloid. Amyloids from bacteria might settle within the brain and impact overall amyloid production. To support your gut microbiome, Bredesen advises using probiotics, prebiotics, and avoiding agents that damage it.

How Microbial Amyloids Affect Beta-Amyloid in the Brain

Robert P. Friedland and Matthew R. Chapman explain that microbial amyloids can influence beta-amyloid in the brain through a process called cross-seeding. Microbial amyloids and beta-amyloid share a similar structure, which allows microbial amyloids to act as “seeds” that promote the aggregation of beta-amyloid. When microbial amyloids enter the brain, they can interact with soluble beta-amyloid, causing it to misfold and clump together more rapidly. This accelerates the formation of beta-amyloid plaques, which are associated with Alzheimer’s disease.

Rebuilding Neural Resilience and Cognitive Function

Bredesen suggests implementing the KetoFLEX 12/3 method to improve cognitive function. This method combines a diet low in carbs, intermittent fasting, and physical activity to repair insulin resistance and supply long-term energy for the brain. Additionally, it can assist in weight loss, reducing your waist size, and lowering your levels of glucose and insulin while fasting. If you're noticing signs of diminishing cognitive abilities or face risks, consider adopting this approach. The initial aim is to change from primarily burning glucose to using fat for fuel to reach mild ketosis.

Who Should Avoid the KetoFLEX 12/3 Method?

While the KetoFLEX 12/3 method can be beneficial for many, it may not be suitable for everyone. According to Eric H. Kossoff, Beth A. Zupec-Kania, and P. E. Amark, individuals with fatty acid oxidation disorders should avoid this approach. These disorders hinder the body's ability to break down fats for energy, making it difficult to enter ketosis. For those with these conditions, attempting to follow a ketogenic diet can lead to serious health complications, including metabolic decompensation. Therefore, it's crucial to consult with a healthcare professional before making significant dietary changes, especially if you have underlying metabolic conditions.

Implementing and Monitoring the Unjection and ReCODE Approaches

Bredesen recommends monitoring glucose levels using a continuous glucose monitor (CGM). This system measures glucose levels at one- to ten-minute intervals for as long as two weeks, using a small sensor inserted beneath your skin as an arm patch. CGM delivers immediate information that lets you observe how particular foods impact your glucose. It also allows you to track your blood sugar during sleep, often alerting you to low blood sugar levels. CGM is fairly affordable but needs a doctor's prescription. It’s typically insured, with Medicare as an option.

(Shortform note: The Centers for Medicare & Medicaid Services (CMS) recently expanded coverage for continuous glucose monitoring (CGM) devices to include all individuals with diabetes who use insulin or have a history of problematic hypoglycemia. However, this coverage is limited to people with diabetes, and those using CGMs for cognitive or general wellness purposes may not be eligible for reimbursement. This means that individuals without diabetes who wish to use CGMs for cognitive health monitoring may need to pay the full cost out of pocket.)
