A New Kind of Neurology

What is preventive neurology?

Preventive neurology is the practice of identifying and addressing brain disease risk factors decades before symptoms appear, using advanced biomarkers, neuroimaging, genetics, and lifestyle medicine.

Most people see a neurologist only after something goes wrong. Preventive neurology flips that model. Instead of waiting for memory loss, brain fog, or a diagnosis, we assess your cognitive risk profile today and build a personalized plan to protect your brain for the decades ahead.

This approach is backed by landmark research, including the Lancet Commission's finding that up to 45% of dementia cases worldwide may be preventable through targeted intervention on modifiable risk factors.

Standard Neurology

React after symptoms appear

Traditional neurology focuses on diagnosis and treatment after cognitive symptoms have already emerged. By this point, significant brain changes have often been underway for years or decades.

Preventive Neurology

Intervene while the brain is healthy

Preventive neurology uses genetic testing (including APOE), blood biomarkers, volumetric brain imaging, and lifestyle medicine to detect and address risk factors before any symptoms develop. The goal is to keep you sharp, not wait until you're not.

Why Now

The window to act is wide open, but it won't be forever

Like arterial plaque building silently before a heart attack, Alzheimer's pathology develops for decades before cognitive decline becomes visible. This is the most critical window in preventive medicine, and most physicians aren't looking.

30s

When it actually starts Brain changes in people who show Alzheimer's symptoms in their 60s can begin as early as their 30s and 40s.

45%

Of dementia is potentially preventable The Lancet Commission identified 14 modifiable risk factors that account for roughly 45% of dementia cases worldwide.

Symptoms needed to begin You don't need to be symptomatic to benefit from preventive neurology. The earlier you act, the greater your advantage.

Patient Stories

They didn't wait for symptoms.
Neither should you.

These patients came in proactively and left with a plan that changed the trajectory of their brain health.

★★★★★

My father had Alzheimer's. I came to Dr. Bilici not because I had symptoms, but because I wasn't willing to sit back and wait. The depth of the evaluation was unlike anything I'd experienced. I finally feel like I have a real plan.

Marcus L.

Tech Founder, 47

★★★★★

I track everything: sleep, HRV, bloodwork. But I'd never had a neurologist look at the whole picture through a prevention lens. Dr. Bilici connected dots my other doctors hadn't even considered. This is what modern medicine should look like.

Serena K.

Physician and Health Optimizer, 41

★★★★★

After turning 50, brain health became a priority. Dr. Bilici's approach is rigorous, evidence-based, and actually personalized. Not a generic wellness plan. My follow-up showed measurable improvements in every biomarker we tracked.

What is preventive neurology and how is it different from standard neurology?

Preventive neurology focuses on identifying and addressing brain disease risk factors before symptoms appear. Standard neurology typically begins after a patient reports cognitive symptoms. By the time most people see a neurologist, significant brain changes have often been developing for decades. Preventive neurology uses tools like APOE genetic testing, blood biomarkers, volumetric brain imaging, and lifestyle medicine to intervene during the window when the most impact is possible.

Who is this practice best suited for?

Our ideal patients are health-conscious individuals aged 30 to 65 who are proactively investing in their cognitive longevity. This includes executives, entrepreneurs, health optimizers, and anyone with a family history of dementia. You do not need symptoms to benefit. In fact, the earlier you engage, the greater the advantage.

Does insurance cover your services?

Dr. Bilici operates a concierge preventive neurology practice, outside the limitations of traditional insurance billing. This allows for extended appointment time, deeper diagnostic evaluation, and truly personalized care. Many patients find the investment significantly more cost-effective than managing late-stage disease. Superbills can be provided for potential out-of-network reimbursement. Discovery calls are complimentary, and details on evaluation pricing are discussed during your call.

What happens at the first appointment?

Your initial consultation is a comprehensive 2-hour session covering your full health history, family history, lifestyle, cognitive baseline, and goals. Dr. Bilici will review your existing records and work with you to design a customized diagnostic and intervention plan. You leave with clarity and a concrete next step.

What is APOE testing and should I get it?

APOE (Apolipoprotein E) genetic testing identifies which variant of the APOE gene you carry. Certain variants, particularly APOE4, are associated with increased Alzheimer's risk. Knowing your APOE status allows for risk-stratified prevention protocols tailored to your specific genetic profile, including targeted interventions for sleep, exercise, nutrition, and pharmacology. Dr. Bilici offers APOE testing and counseling as part of comprehensive cognitive risk assessment.

I'm already seeing a neurologist. Can I still work with Dr. Bilici?

Absolutely. Many patients have existing neurology care and come to Dr. Bilici specifically for a preventive and lifestyle-focused perspective. He works collaboratively with your existing care team and provides a complementary layer of proactive monitoring and optimization.

Do you offer telehealth appointments?

Yes. Dr. Bilici offers both in-person and telehealth appointments, making preventive neurology accessible regardless of your location. The discovery call is always conducted virtually, and many follow-up consultations can be held remotely as well.

How often will we meet after the initial evaluation?

Follow-up cadence is personalized to your plan, but most patients have formal appointments every 6 to 12 months with regular check-ins in between. You're never left waiting for your next appointment when questions arise.
