Why Brain Health Matters
It’s Never Too Early—or Too Late—to Support Your Brain
Changes associated with cognitive decline can begin years before they noticeably affect memory or daily life. That creates an important opportunity to identify risk factors early, establish a cognitive baseline, and support long-term brain health before symptoms develop.
But prevention is only part of the story. Even when memory changes, mild cognitive impairment, or early Alzheimer’s disease are already present, there may still be meaningful opportunities to address the factors contributing to decline. Our goal is to understand where you are today and create a personalized plan to protect remaining function, support improvement where possible, and promote greater independence and quality of life.
Whether you are being proactive because of family history or APOE4 status—or seeking help for changes already underway—the best time to begin is now.
Who Is This Program For?
Whether you’re looking to prevent cognitive decline or address memory changes, we’ll meet you where you are.
Prevention Program
Apollo Health PRECODE® Approach
Designed for adults who want to understand their brain health before significant symptoms develop.
This program may be right for you if you:
- Have a family history of Alzheimer’s disease
- Have learned you’re an APOE4 carrier
- Want a baseline cognitive assessment (recommended beginning around age 45)
- Want to optimize your long-term brain health and cognitive longevity
- Are interested in a proactive, evidence-informed approach to prevention
Goal:
Identify your unique risk factors and create a personalized plan to reduce risk and support lifelong brain health.
Cognitive Optimization Program
Apollo Health RECODE® Approach
Designed for adults who have noticed cognitive changes or have already received a diagnosis.
This program may be right for you if you:
- Are forgetting names, appointments, or conversations more often
- Have Subjective Cognitive Impairment (SCI)
- Have Mild Cognitive Impairment (MCI)
- Have been diagnosed with Alzheimer’s disease
- Want to complement the care you’re receiving from your neurologist
Goal:
Identify the factors contributing to cognitive decline and develop a personalized treatment plan to support cognitive function, independence, and quality of life.

Our Precision Medicine Approach
We Don’t Just Ask If Your Brain Is Changing—We Ask Why.
Brain health is influenced by many interconnected factors. Rather than focusing on a single lab value or diagnosis, we use the Apollo Health RECODE® and PRECODE® framework to understand your brain from multiple perspectives. Throughout your care, we evaluate three core areas simultaneously to create a personalized plan that’s tailored to your unique biology, health history, and goals.
Understanding Your Current Cognitive Health
Before creating a plan, it’s important to understand how your brain is functioning today. Depending on your goals and symptoms, your evaluation may include:
Comprehensive medical and family history
Cognitive assessment and screening
FDA-approved blood biomarkers for Alzheimer's disease, when appropriate
Advanced brain imaging, when indicated
Our goal is to establish a meaningful baseline so we can better understand where you are today and monitor your progress over time.
Identifying Your Individual Risk Factors
One of the hallmarks of the RECODE® approach is identifying the specific factors that may be contributing to cognitive decline—or increasing future risk. We evaluate the six major categories described in the Bredesen framework:
| Risk Factor Category | What We Look For |
|---|---|
| Inflammatory | Chronic inflammation can affect brain function and is associated with an increased risk of cognitive decline. We look for underlying contributors such as chronic infections, oral health concerns, autoimmune conditions, and other sources of inflammation. |
| Glycotoxic | Blood sugar dysregulation and insulin resistance can impair the brain’s ability to efficiently use energy. Optimizing metabolic health is a key part of supporting long-term cognitive function. |
| Atrophic | The brain depends on adequate hormones, vitamins, minerals, and other nutrients to function optimally. We evaluate whether nutritional deficiencies or hormonal imbalances may be limiting your brain’s resilience. |
| Toxic | Environmental toxins, mold exposure, heavy metals, and other toxic burdens may contribute to cognitive symptoms in some individuals. When appropriate, we investigate these potential contributors. |
| Vascular | Healthy blood flow is essential for brain health. We assess cardiovascular and metabolic factors that influence the delivery of oxygen and nutrients to the brain. |
| Traumatic | Previous head injuries, repetitive trauma, and other neurological insults can influence long-term cognitive health and are considered as part of your overall risk profile. |
To better understand these risk factors, we may recommend:
- Comprehensive health and family history
- Standard laboratory testing (often coordinated through your primary care provider or covered by insurance)
- Cognitive genomics
- Sleep apnea testing
- Functional testing, such as mycotoxins, heavy metals, or cortisol, when clinically appropriate
Our goal is to identify the factors that are most relevant to your brain health so we can focus our efforts where they’re likely to have the greatest impact.
Optimizing the Foundations of Brain Health
Once we understand your unique risk profile, we create a personalized plan that strengthens the lifestyle factors known to support lifelong cognitive health:
Nutrition
Exercise
Sleep optimization
Stress resilience
Brain stimulation and cognitive engagement
Targeted supplementation
We recognize that lasting change happens over time. Rather than asking you to change everything at once, we’ll help you prioritize the interventions most likely to benefit your brain and implement them at a pace that feels realistic and sustainable.
What Makes Our Program Different
A Different Approach to Brain Health
We believe exceptional brain health care goes beyond making a diagnosis or recommending supplements. Our goal is to understand the factors influencing your cognitive health and partner with you to create a personalized roadmap for prevention or treatment.

Patient Success Stories
Helping Patients Feel Informed, Empowered, and Hopeful
Choosing a provider for your brain health is an important decision. Here’s what a few of our patients have shared about their experience at Aya Naturopathic Medicine.
“If you want to have a conversation about Alzheimer’s and Alzheimer’s prevention, look no further. Dr. Jeffrey provides research-based approaches—she’s incredibly knowledgeable and offers truly compassionate care. Working with her has exceeded my expectations.”

“This is a great practice! They truly take time with you and make sure you understand everything without making assumptions. The protocols are written out in full detail so you know exactly what the plan is and why. I really appreciate that they are very cost conscious and go out of their way to provide affordable options. I highly recommend Aya Naturopathic Medicine!”

“Alzheimer’s runs deep in my family, so I wanted to be proactive about protecting my brain health. Dr. Jeffrey guided me through lifestyle changes, nutrition, exercise, and reducing environmental exposures that were increasing my risk. Within a few months, my cholesterol and prediabetes markers had returned to the normal range, and I felt healthier overall. Most importantly, I no longer feel like I’m waiting for Alzheimer’s to happen—I feel like I have a partner in my healthcare.”
