==Introduction==
==Introduction==
[https://www.drbredesen.com/thebredesenprotocol/ Dr. Dale Bredesen] has created a protocol that involves multiple interventions to address specific components of AD pathology that research has identified to date. Each intervention is measured and tweaked over time by using blood tests, cognitive evaluations and other markers of overall health improvements. His analogy is to think of AD as a leaky roof - there are as many as 36 leaks in in the AD roof that need to be addressed to stop the problem. Not every patient will have the same leaks, and the protocol is customized based on the patient’s genetics, current health and lifestyle.


His first published paper on the protocol, [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4221920/ Reversal of Cognitive Decline], highlighted 10 case studies. Of those 10 people, nine showed enough improvement to return to normal life activities. Since then, several hundred people with cognitive impairment have followed the protocol, and most have seen a reversal of cognitive impairment. Dr. Bredesen is currently partnering with the Cleveland Clinic to test the protocol in a larger trial.
The protocol in this wiki is based on Dr Bredesen’s first book, '''''The End of Alzheimer’s'''''. With the exception of some new findings as well as some tweaks and refinements, his second book, '''''The End of Alzheimer’s Program''''' maintains the ReCode protocol, but presents practical information and steps to ''implement'' the protocol.   Changes or new information from Dr Bredesen’s second book:


Although Bredesen does not see private patients, he is in the process of making it available to the wider public with the help of doctors certified in the protocol through [http://www.drbredesen.com/ MPI Cognition].  His previous affiliation with [https://museslabs.com/ Muses Labs] has ended.
* The cognoscopy now has some new tests and some biomarker goals have been refined, the table below in the resources section reflects these updated tests and values
* The original 3 types of Alzheimer’s has been expanded to 6 types:  Type 1 Inflammatory or hot, Type 2 atrophic or cold, Type 1.5 glycotoxic or sweet, Type 3 Toxic or vile, Type 4 vascular or pale, Type 5 – traumatic or dazed

* A discussion of the KetoFLEX 12/3 Brain Food Pyramid.  The bottom layer, the foundation, is overnight fasting.  Above that is non starchy vegetables and healthy fats.  Next is prebiotics, resistant starch, and probiotics.  Second from the top is animal protein and fruit.  And the top of the pyramid is indulgences.  For a video discussing this pyramid: [https://www.facebook.com/drdalebredesen/videos/618182625501890/ Video "JG#2" from Facebook page "Dale Bredesen, MD"]
 
* The role of oral health in cognitive decline
 
* Detailed information about dementogens
 
* Personalized nutritional supplements
 
* Plan for gut health and how to optimize your microbiome and holobiome


* Plus interspersed throughout the book are inspiring stories of patients who have successfully reversed cognitive decline


Bredesen’s protocol has not been tested as a preventative. That said, research has shown that amyloid-β is deposited in E4 carriers as early as their thirties so addressing components early will likely lead to better health in aging. Members on the APOE4.Info forum who follow the protocol report improvements not only in health, but cognition, even if they do not have an SCI or MCI diagnosis.




The following list includes summaries, a selection of research references and suggested strategies related to the intervention targets of the protocol.
[https://www.drbredesen.com/thebredesenprotocol/ Dr. Dale Bredesen] has created the ReCODE protocol that involves multiple strategies to address specific health issues that contribute to Alzheimer's Disease (AD). The results of each strategy are measured by using blood tests, cognitive evaluations, and other markers of overall health improvements. Actions are tweaked over time to aim for optimal lab and evaluation results. His analogy is to think of AD as a leaky roof - there are as many as 36 leaks in the AD roof that need to be addressed to stop the problem. Not every patient will have the same leaks, and the protocol is customized based on the patient’s genetics, current health, and lifestyle.
 
In 2014, his first published paper on the protocol, [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4221920/ Reversal of Cognitive Decline], highlighted 10 case studies. Of those 10 people, nine showed enough improvement to return to normal life activities. Several hundred people with cognitive impairment have since followed the protocol, and most have seen a reversal of cognitive impairment. He published results of reversing various levels of cognitive decline in [https://www.omicsonline.org/open-access/reversal-of-cognitive-decline-100-patients-2161-0460-1000450.pdf Reversal of Cognitive Decline: 100 patients], published October 2018. His  book ''The End of Alzheimer's'', published August 2017 discusses his protocol and explains many of the mechanisms of Alzheimer's. 
 
Bredesen’s protocol has not been tested as a preventative, however in a May 2019 podcast interview, Dr Bredesen did say that he’s never had someone at risk come in for prevention and develop even mild cognitive impairment. Research has shown that amyloid-β is deposited in E4 carriers as early as their thirties, so addressing components prior to experiencing cognitive impairment symptoms will likely lead to better health and cognition in aging. Members on the APOE4.Info forum who follow the protocol report improvements not only in health but also in cognition, even if they do not have an SCI or MCI diagnosis.
 
Although Bredesen does not see private patients, he has made his protocol available to those seeking doctor assistance through [https://www.ahnphealth.com/ AHNP: Precision Health].  MPI Cognition, his previous affiliation, was acquired by AHNP and his prior affiliation with [https://museslabs.com/ Muses Labs] has ended.

'''Tracking results:'''
Our member "optimize" made a Google spreadsheet using the recommended Cognoscopy test values in The End of Alzheimer's. This spreadsheet is a simple table to help you track your latest test results, with values flagged as "high", "low", or "in range". It's intended as a quick way to organize test results, and see at a glance where to make improvements.
 
The link to make your own copy of the spreadsheet for your private use is here: https://goo.gl/8t2dxi
 
Please note! The copied spreadsheet will let you type in the white areas, but this may cause errors in the formulas. If you accidentally type in a white area, hit "ctrl-Z" a few times to remove the typing, or download a fresh copy of the spreadsheet.
 
 
'''Summary of key tests for ReCode Protocol'''
Taken from table 1 of Dr Bredesen's second book '''''The End of Alzheimer's Program'''''  provided for quick reference, refer to the book for specific information.  If you are following his first book, note that some of the biomarkers have changed.

Introduction

The protocol in this wiki is based on Dr Bredesen’s first book, The End of Alzheimer’s. With the exception of some new findings as well as some tweaks and refinements, his second book, The End of Alzheimer’s Program maintains the ReCode protocol, but presents practical information and steps to implement the protocol. Changes or new information from Dr Bredesen’s second book:

  • The cognoscopy now has some new tests and some biomarker goals have been refined, the table below in the resources section reflects these updated tests and values
  • The original 3 types of Alzheimer’s has been expanded to 6 types: Type 1 Inflammatory or hot, Type 2 atrophic or cold, Type 1.5 glycotoxic or sweet, Type 3 Toxic or vile, Type 4 vascular or pale, Type 5 – traumatic or dazed
  • A step by step guide on the order of events for reversing cognitive decline. From chapter two: 1.address insulin resistance 2. get into ketosis 3. optimize nutrient, hormone and trophic factor (growth factor) support 4. resolve and prevent inflammation 5. treat chronic pathogens 6. identify and remove toxins 7. rule out sleep apnea and optimize sleep
  • A discussion of the KetoFLEX 12/3 Brain Food Pyramid. The bottom layer, the foundation, is overnight fasting. Above that is non starchy vegetables and healthy fats. Next is prebiotics, resistant starch, and probiotics. Second from the top is animal protein and fruit. And the top of the pyramid is indulgences. For a video discussing this pyramid: Video "JG#2" from Facebook page "Dale Bredesen, MD"
  • The role of oral health in cognitive decline
  • Detailed information about dementogens
  • Personalized nutritional supplements
  • Plan for gut health and how to optimize your microbiome and holobiome
  • Plus interspersed throughout the book are inspiring stories of patients who have successfully reversed cognitive decline


Dr. Dale Bredesen has created the ReCODE protocol that involves multiple strategies to address specific health issues that contribute to Alzheimer's Disease (AD). The results of each strategy are measured by using blood tests, cognitive evaluations, and other markers of overall health improvements. Actions are tweaked over time to aim for optimal lab and evaluation results. His analogy is to think of AD as a leaky roof - there are as many as 36 leaks in the AD roof that need to be addressed to stop the problem. Not every patient will have the same leaks, and the protocol is customized based on the patient’s genetics, current health, and lifestyle.

In 2014, his first published paper on the protocol, Reversal of Cognitive Decline, highlighted 10 case studies. Of those 10 people, nine showed enough improvement to return to normal life activities. Several hundred people with cognitive impairment have since followed the protocol, and most have seen a reversal of cognitive impairment. He published results of reversing various levels of cognitive decline in Reversal of Cognitive Decline: 100 patients, published October 2018. His book The End of Alzheimer's, published August 2017 discusses his protocol and explains many of the mechanisms of Alzheimer's.

Bredesen’s protocol has not been tested as a preventative, however in a May 2019 podcast interview, Dr Bredesen did say that he’s never had someone at risk come in for prevention and develop even mild cognitive impairment. Research has shown that amyloid-β is deposited in E4 carriers as early as their thirties, so addressing components prior to experiencing cognitive impairment symptoms will likely lead to better health and cognition in aging. Members on the APOE4.Info forum who follow the protocol report improvements not only in health but also in cognition, even if they do not have an SCI or MCI diagnosis.

Although Bredesen does not see private patients, he has made his protocol available to those seeking doctor assistance through AHNP: Precision Health. MPI Cognition, his previous affiliation, was acquired by AHNP and his prior affiliation with Muses Labs has ended.

Tracking results: Our member "optimize" made a Google spreadsheet using the recommended Cognoscopy test values in The End of Alzheimer's. This spreadsheet is a simple table to help you track your latest test results, with values flagged as "high", "low", or "in range". It's intended as a quick way to organize test results, and see at a glance where to make improvements.

The link to make your own copy of the spreadsheet for your private use is here: https://goo.gl/8t2dxi

Please note! The copied spreadsheet will let you type in the white areas, but this may cause errors in the formulas. If you accidentally type in a white area, hit "ctrl-Z" a few times to remove the typing, or download a fresh copy of the spreadsheet.

Videos and interviews

  • He cites 6 types of Alzheimer's: (1) inflammatory (2) atrophic (1.5) glycotoxic (3) toxic (4) vascular and (5) traumatic. Vascular and traumatic are new since publication of his book
  • In his markers for glycotoxicity, he cites fasted insulin of 5.0 (his book cites 4.5) or lower and HbA1c 4.5 to 5.2 (the book cites less than 5.6)
  • Dr Bredesen said that the Big Four to avoid are: grains, simple carbs, dairy, and lectins. Pro-inflammatory lectins have been added since publication of his book.
  • He added another mold/mycotoxin to his list: Wallemia. The big 5 molds are now: Stachybotrys, Aspergillus, Penicillium, Chaetomium, and Wallemia.


Dr Bredesen's Papers

  • The first version of Dr Bredesen’s protocol (which is similar to the above) can be found in his paper: Reversal of cognitive decline: A novel therapeutic program, published September 2014, https://www.ncbi.nlm.nih.gov/pubmed/25324467

Subsequent papers of Dr Bredesen do not address his protocol, but further examine his findings. They include:

This paper addresses the common criticism that the original paper only covered a small number of patients. This paper documents improvement in cognition of 100 patients treated by several different physicians thus providing further support for a randomized, controlled clinical trial of the protocol and overall approach:
