Cognitive Testing & Brain Health → Get clarity on memory, focus, and cognition with personalized testing and advanced brain imaging.
Longevity & Healthy Aging → Measure what matters, slow what you can, and build a plan for energy, resilience, and health-span.
Testing & Labs → Epigenetics, MRI volumetrics, QEEG, metabolic/hormone panels, and more — coordinated for you.
Why Precision Medicine?
Cognitive decline and aging aren’t one-variable problems. We evaluate root causes across your biology, then design a plan that fits real life.
- Investigative: We look across genetics, inflammation, sleep, metabolism, toxins, hormones, and brain structure/function.
- Whole-Body: Your brain reflects your body; we treat systems, not silos.
- Lifestyle-Oriented: Food, movement, sleep, stress, and brain training are foundational—not afterthoughts.
- Patient-Centered: Your goals steer the plan; we adjust together.
- Science-Aligned: We follow data and use validated tools and multidomain strategies.
- Results-Measured: Baselines, checkpoints, and retesting guide each next step.
The Stories That Keep Us Going
The Rezilir Way
Our Precision Medicine Process
The Rezilir Way is simple: we listen first, then measure what matters. With all key diagnostics and therapies coordinated under one roof, we map the root causes behind your symptoms and turn them into a personalized plan you can actually follow. Here’s what the first 60 days typically look like…
Deep Diagnostic Discovery
Your clinician reviews your history and orders a focused set of prioritized tests to uncover the drivers behind your symptoms and risks. Common tools include genetic risk screening, cognitive testing, MRI volumetrics, QEEG brain mapping, metabolic and inflammatory markers, sleep screening, toxin exposure assessment, and hormone/nutrient panels.2.
Your Personalized Plan
With your results in hand, we build a multilayered plan across nutrition, sleep, movement, stress, and targeted supplements—adding advanced therapeutics where appropriate (for example, hyperbaric oxygen therapy, photobiomodulation, or hormone optimization). Medications may be included when indicated.3.
Ongoing Partnership
We’ll track progress with scheduled check-ins, repeat cognitive testing where appropriate, and select retesting of key biomarkers. Plans evolve with your data—and your life.
