Families navigating an Alzheimer’s diagnosis often encounter two very different philosophies of care. Traditional medical care focuses on managing symptoms with medication and supportive therapy. Functional medicine takes a broader approach: it asks what is causing the decline at the biological level and aims to address those underlying drivers directly.
Neither approach is inherently right or wrong — they’re built on different assumptions about how to help a person living with Alzheimer’s. Understanding both lets families make better-informed decisions and, in many cases, combine elements of each. This article walks through the differences, where they overlap, and how a residential precision-medicine program in Michigan brings the two together.
Quick Facts
| Traditional care: manages symptoms through medication, therapy, and supportive services. Widely available and often insurance-covered. Functional medicine: an approach that investigates and addresses the underlying biological drivers of cognitive decline. Precision medicine: the testing-driven methodology used in functional-medicine practice. Examples include the ReCODE Protocol developed by Dr. Dale Bredesen. They are not opposites: the most comprehensive approach combines elements of both, with medication continuing under the supervision of a prescribing clinician while a precision-medicine program addresses biological drivers. In Michigan: Michigan Cognitive Recovery Center delivers the residential ReCODE+ For Facilities Program at 4851 Lakeshore Rd, Fort Gratiot Township, MI 48059. 810-385-3185. |
Functional Medicine, Precision Medicine, and ReCODE — What’s the Relationship?
These three terms are often used loosely and sometimes interchangeably, which causes confusion. They are related but not identical, and the relationship is straightforward once you see it laid out:
- Functional medicine is the broader philosophical approach. Its core idea is that chronic diseases — including cognitive decline — have multiple underlying drivers, and that addressing those drivers produces better outcomes than treating symptoms alone.
- Precision medicine is the methodology functional-medicine practitioners use. It relies on comprehensive testing to identify which biological drivers are active in each individual, then builds a personalized care plan around those specific findings.
- The ReCODE Protocol is the leading evidence-based implementation of precision medicine for cognitive decline. Developed by Dr. Dale Bredesen and delivered through Apollo Health, it identifies and addresses six specific categories of biological contributors.
Most adults searching for “functional medicine for Alzheimer’s” are really looking for the ReCODE Protocol or something like it — the specific implementation, not just the philosophy.
What Traditional Alzheimer’s Care Looks Like
Traditional Alzheimer’s care follows the standard medical model used by primary care doctors, neurologists, and most memory-care providers. The primary goal is symptom management and disease-progression slowing.
Common components
- Diagnosis and testing. Cognitive assessments (such as the Montreal Cognitive Assessment), brain imaging (MRI or PET), and standard blood work to confirm Alzheimer’s and stage the disease.
- Medication management. Cholinesterase inhibitors (donepezil/Aricept, rivastigmine/Exelon, galantamine/Razadyne), NMDA receptor antagonists (memantine/Namenda), and increasingly the anti-amyloid drugs (lecanemab/Leqembi, donanemab/Kisunla).
- Therapy and behavioral support. Counseling, support groups, and behavioral interventions for mood swings, anxiety, or agitation.
- General lifestyle advice. Recommendations to “eat well” and “stay active” — usually not personalized to the individual’s testing or biology.
- Long-term and end-of-life care. As the disease progresses, the focus shifts to comfort, safety, and caregiver support.
What traditional care does well
- Backed by extensive clinical trial evidence and decades of research.
- Provides access to medications and specialists.
- Often covered, at least partially, by insurance and Medicare.
- Widely available across the U.S.
Where traditional care has limits
- Focuses on managing decline rather than addressing root causes.
- Does not investigate inflammation, hormone status, metabolic health, toxins, vascular contributors, or traumatic-brain-injury history in any depth.
- Lifestyle guidance is typically generic rather than personalized.
- Even disease-modifying anti-amyloid drugs only target one mechanism.
What Functional Medicine for Alzheimer’s Looks Like
Functional medicine flips the question. Rather than asking “what drug treats this disease?” it asks “why is this person’s brain declining, and what can we do about those specific factors?” The core assumption is that cognitive decline is multi-factorial — driven by several biological processes operating at once — so the most powerful intervention investigates and addresses each one.
How a functional-medicine approach works
- Comprehensive root-cause testing. Detailed labs and assessments looking at inflammation, hormones, nutrient levels, gut health, toxin exposures, vascular contributors, and more — far more thoroughly than a standard blood panel.
- Personalized nutrition. Diets like the MIND diet, the Mediterranean diet, or the more cognitively targeted KetoFLEX 12/3 used in the ReCODE Protocol.
- Lifestyle interventions. Sleep, exercise, stress management, social engagement, and brain stimulation — implemented daily, not just suggested.
- Targeted supplementation. Based on testing — addressing specific deficiencies rather than generic supplement protocols.
- Toxin and exposure management. When mold, heavy metals, or chemical exposures are identified, they are addressed through environmental and medical means.
- Brain stimulation and cognitive engagement. Structured cognitive training that supports neuroplasticity.
What a functional-medicine approach does well
- Investigates underlying drivers rather than only managing symptoms.
- Personalizes the care plan to each individual’s testing.
- Encourages prevention and early intervention.
- Empowers families to play an active role.
Where functional medicine has limits
- Often not fully covered by insurance, especially for the testing and supplements that are central to the approach.
- Requires consistency — particularly in the lifestyle pillars — that is difficult to maintain at home.
- The clinical evidence base is younger than for traditional pharmaceutical approaches, though it is growing rapidly.
Side-by-Side Comparison
| Feature | Traditional care | Functional / precision-medicine approach |
| Primary goal | Manage symptoms; slow progression | Identify and address root causes |
| Approach | Standardized; same drugs at similar doses across patients | Personalized based on individual testing |
| Tools | Medications, supportive therapy, behavioral interventions | Personalized nutrition, lifestyle, supplements, targeted clinical care, with medication when prescribed |
| Testing depth | Standard cognitive and lab tests | Comprehensive labs, biomarkers, and ongoing re-testing |
| Family involvement | Generally supportive caregiver role | Active partner in implementation and tracking |
| Insurance coverage | Often covered | Often partial or out-of-pocket |
| Best for | Any stage; standard of care | Strongest evidence in early-stage decline (SCI, MCI, early-stage Alzheimer’s) |
In short: traditional care treats the disease; a functional or precision-medicine approach treats the person.
What the Research Shows
There is no cure for Alzheimer’s in either model. Research on multifactorial, functional-style programs, however, is increasingly compelling for early-stage disease.
A 2022 prospective trial by Toups, Hathaway, Bredesen, and colleagues — published in the Journal of Alzheimer’s Disease — reported measurable cognitive improvement in participants with MCI or early-stage Alzheimer’s following a multifactorial precision-medicine program. According to Apollo Health, two published clinical studies have reported 75–84% improvement in early-stage participants on the ReCODE Protocol, and the 2025 randomized controlled trial reported 90% improvement and an effect size 600% greater than the leading FDA-approved Alzheimer’s drug.
Outcomes vary by individual, and earlier-stage participants tend to see the strongest results. For complete clinical information, please visit Apollo Health.
Combining the Two Approaches
In practice, families do not have to choose one or the other. The most comprehensive approach combines them: medication continues when prescribed by the patient’s clinician, while a precision-medicine program investigates and addresses the biological drivers medication does not target. This is what we’ve covered in detail in our article on why medication alone falls short in Alzheimer’s care.
A Hypothetical Scenario
Consider a hypothetical patient — call her “Mrs. R.” — who has been recently diagnosed with mild cognitive impairment. Under traditional care, her primary care physician prescribes a cholinesterase inhibitor, recommends she “stay active,” and refers her to a memory-care support group.
Under a functional or precision-medicine approach, the same patient also undergoes comprehensive testing — and the testing reveals untreated insulin resistance, a low vitamin D level, ongoing inflammation of unclear origin, and a history of a head injury 30 years prior. Each of those findings becomes a target. Her care plan now includes the medication her physician prescribed and personalized nutrition, sleep optimization, supplementation matched to her deficiencies, targeted anti-inflammatory work, structured exercise, and ongoing biomarker monitoring.
The hypothetical illustrates the central difference. The same diagnosis can lead to two very different care plans depending on which philosophy guides the approach — and which questions get asked at the start.
How Michigan Cognitive Recovery Center Brings the Two Together
Michigan Cognitive Recovery Center at Lakeshore Woods Senior Living is one of only two U.S. facilities offering the ReCODE+ For Facilities Program. The 12-month residential program delivers the precision-medicine approach in full daily structure, while continuing to work with each resident’s prescribing clinician on medication. For a deeper look at the program’s structure, see our guide to ReCODE residential care in Michigan, and for the broader framework see our guide to precision medicine for early-stage Alzheimer’s.
What that means in practice for a family weighing functional vs. traditional care:
- Comprehensive testing identifies which of the six biological contributors to cognitive decline are active for that resident.
- A personalized ReCODE Report™ translates the testing into a daily care plan.
- The Bredesen Seven — nutrition (KetoFLEX 12/3), exercise, sleep optimization, stress management, brain stimulation, detoxification, and targeted supplements — runs daily under trained staff.
- 24/7 dementia-care support handles the practical implementation that families struggle to maintain at home.
- Continuous biomarker re-testing shows what is working and what needs adjustment.
- Coordination with the resident’s clinician keeps medication management consistent and informed.

Simple Ways to Support Brain Health at Home
Even before — or alongside — formal program participation, the lifestyle foundations of a functional approach are universally beneficial. Eat real food (especially leafy greens and healthy fats), move every day, prioritize sleep, stay socially and intellectually engaged, manage stress, and keep your blood pressure, blood sugar, and cholesterol in healthy ranges. For a fuller breakdown, see our guide to lifestyle changes for brain health and our guide to the KetoFLEX 12/3 diet.
Frequently Asked Questions
What are the main differences between functional and traditional Alzheimer’s care?
Traditional care focuses on managing symptoms with medication, supportive therapy, and behavioral interventions. A functional or precision-medicine approach investigates and addresses the underlying biological drivers — including inflammation, hormone and nutrient deficiencies, metabolic dysfunction, toxin exposures, vascular dysfunction, and traumatic brain injuries — through personalized care plans built on testing.
Is functional medicine the same as the ReCODE Protocol?
Not exactly. Functional medicine is the broader philosophical approach. Precision medicine is its testing-driven methodology. The ReCODE Protocol developed by Dr. Dale Bredesen is the leading evidence-based implementation of that methodology for cognitive decline.
Can functional medicine help slow cognitive decline in early Alzheimer’s?
Research on multifactorial, precision-medicine programs is increasingly encouraging for early-stage Alzheimer’s and MCI, including a 2022 prospective trial published in the Journal of Alzheimer’s Disease and a 2025 randomized controlled trial. Outcomes vary by individual, and earlier-stage participants tend to see the strongest results. It is not a cure.
Should I choose traditional care or functional medicine?
You don’t have to choose. The most comprehensive approach combines them — medication continuing under your physician’s supervision while a precision-medicine program addresses the biological drivers medication does not target.
Is functional medicine for Alzheimer’s covered by insurance?
Coverage varies. Some components — such as standard lab work and physician visits — may be partially covered. Specialized testing, supplements, and residential program fees are often out-of-pocket. Families should check directly with their insurance providers.
