Bredesen Protocol (ReCODE™) and the HormoneSynergy® Model: A Shared Precision Approach to Brain Health
We’ve followed Dr. Bredesen’s work for years and attended multiple lectures because it aligns with how we approach cognitive longevity. The Bredesen protocol (ReCODE) supports memory improvement by addressing sleep, insulin resistance, inflammation, hormones, and nutrients. At HormoneSynergy® Clinic (Portland & Lake Oswego), we apply these same principles to support long-term cognitive performance and brain resilience.
Key Takeaways: Precision Medicine for Cognitive Longevity
- The Bredesen protocol (ReCODE™) applies precision medicine to cognitive decline by addressing multiple root causes—rather than relying on a single intervention.
- A December 2025 preprint reported improvements in memory improvement, executive function, processing speed, and cognitive symptoms in MCI treatment and early dementia using a multi-domain approach.
- Key “brain levers” include sleep quality (and sleep apnea/Upper Airway Resistance Syndrome risk), insulin resistance, inflammation, vascular health, hormone balance, and nutrient sufficiency.
- Brain fog often overlaps with these same drivers—especially sleep disruption, metabolic dysfunction, inflammation, and hormone imbalance—making a precision approach useful even before MCI.
- At HormoneSynergy® Clinic (Portland & Lake Oswego), Dr. Retzler has followed Dr. Bredesen’s work for years, completed two in person trainings and integrated key principles into our broader longevity and healthspan model.
- Our focus is not a short-term “protocol sprint,” but a sustainable, measurable plan that supports attention, memory, processing speed, and resilience over decades.
- Slowing Cognitive Decline is best approached early: protect sleep, optimize cardiometabolic health, build strength and aerobic capacity, manage blood pressure and lipids, reduce inflammation, and reassess objective markers over time.
- Supplements can support the plan, but they work best when targeted—based on labs, symptoms, and goals—rather than used as random stacks.

Why Dr. Bredesen’s work matters in the cognitive health conversation
Cognitive decline is often framed as inevitable—something to fear, but not something you can influence until a pharmaceutical breakthrough arrives. That framing is outdated.
At HormoneSynergy® Clinic (Portland & Lake Oswego, Oregon), we’ve followed the work of Dr. Dale Bredesen for years. We’ve attended multiple lectures, followed his evolving clinical framework, and integrated many of its most durable principles into our own approach to longevity medicine. If you're a current patient, you might remember seeing his books in our waiting room or even watched his "End of Alzheimer's" videos while receiving an IV at our Portland and Lake Oswego office.
***To be clear: we are not presenting ourselves as a “Bredesen" or a "ReCode" clinic, and we are not claiming a formal collaboration. What we are saying is simple and honest: we respect this work, we’ve learned from it, and we’ve integrated our shared principles of slowing and even preventing cognitive decline into the HormoneSynergy® model because it aligns with how we already care for patients.***
What the December 2025 preprint adds
A December 2025 preprint (not yet peer-reviewed) evaluated a personalized, multi-domain precision-medicine program in adults with mild cognitive impairment (MCI) or early dementia. Compared with standard care, the precision group improved in memory improvement, executive function, processing speed, overall cognitive performance, and cognitive symptom severity.
This was not a “magic bullet.” It was a systems approach—nutrition, exercise, sleep evaluation, stress regulation, targeted nutrients, and individualized support across multiple risk domains—reinforcing a point many clinicians observe: the brain often improves when the whole body improves.
How HormoneSynergy® integrate these principles into our longevity model
We do not treat cognition as a separate “brain-only” program. We treat it as a core pillar of longevity—alongside cardiovascular prevention, metabolic health, muscle preservation, and hormone optimization.
1) Sleep is brain medicine
Sleep-disordered breathing and nocturnal hypoxia are among the most overlooked drivers of brain fog, poor focus, and long-term cognitive risk.
Sleep Optimization & Sleep Apnea Screening
2) Metabolic health is cognitive health
Insulin resistance and glycation are strongly associated with cognitive decline and reduced executive function over time. This is why we focus on sustainable metabolic optimization—including appropriate medical weight loss support.

3) Vascular health protects the brain
The brain is a high-demand organ dependent on blood flow, oxygen delivery, and vascular integrity. This is why we consider cardiovascular prevention central to cognitive longevity.
Preventive Cardiology & Early Detection
4) Muscle, body composition, and the brain are connected
Muscle is not just about appearance. It supports insulin sensitivity, inflammation control, mitochondrial signaling, and resilience under stress—all relevant to brain health.
5) Hormones influence cognition—especially in midlife
Hormonal signaling affects sleep, mood, energy metabolism, inflammation, and cognitive performance. Hormone optimization isn’t a shortcut, but when it’s appropriate, it can be a meaningful lever.
Hormone Optimization & Healthy Aging
6) Gut health and inflammation affect cognitive symptoms
Many patients experiencing brain fog, fatigue, or mood instability have inflammatory and gut-related patterns that deserve attention.

Nutritional Supplements: supportive, targeted, and measured
The Bredesen protocol includes targeted supplementation. We agree with that approach—when it’s done thoughtfully. RetzlerRx® exists because we see the opposite every day: people spending large amounts of money on random supplement stacks while ignoring sleep apnea, insulin resistance, blood pressure, under-muscled aging, or chronic inflammation.
In our model: supplements support the plan—but they don’t replace the plan.
Brain fog, MCI treatment, and Alzheimer’s prevention often share the same root causes
One of the most useful insights from precision cognitive medicine is that the same drivers often appear across different stages: brain fog, reduced processing speed, early executive dysfunction, MCI treatment, and Alzheimer’s risk.
The earlier you intervene, the more options you tend to have. That’s why we encourage patients to think about cognitive longevity like heart health: not as something you react to, but as something you build.
Our clinical bottom line
We view Dr. Bredesen’s work as a meaningful contribution to the cognitive medicine conversation. We’ve followed it for years, learned from it, and integrated many of its best principles into the HormoneSynergy® longevity model—because it complements what we already do: measurable, sustainable, whole-body optimization.
If your goals include improved memory, sharper executive function, faster processing speed, fewer cognitive symptoms, and a higher probability of maintaining independence over time, a precision approach may be worth exploring—especially early.
