Cognitive longevity is the practice of protecting brain function, including memory, focus, processing speed, and mood, as you age, the same way longevity medicine protects the rest of the body. It is preventive optimization, not a disease treatment. I’m a board-certified neurologist. I spent years diagnosing complex brain conditions, and that is exactly why I think the brain deserves its own strategy instead of being an afterthought to hormones and IV drips.
This is also where overpromising does the most harm. The brain is the first place people fear aging, and that fear sells supplements. So I will be blunt about what the evidence supports — and what it does not. No peptide, IV, or supplement reverses dementia or Alzheimer’s disease. Cognitive longevity is about protecting the brain you have and addressing risk factors early, with honest clinical judgment.
At LiveNow Longevity we serve Las Vegas, Henderson, Summerlin, Green Valley, and all of Nevada — in person at our clinic at Eastern Avenue and the 215, or by secure telehealth. Telemedicine consultations are available for Nevada residents for ongoing management.
What Cognitive Longevity Means
Cognitive longevity asks a simple question: how do you keep your brain working well for as long as possible? The answer is not one product. It is a combination of fundamentals — exercise, sleep, vascular and metabolic health, and treating the conditions that quietly drag cognition down — plus, for some people, targeted support considered only after a real evaluation.
The strongest evidence for protecting the aging brain points to unglamorous fundamentals: regular exercise, quality sleep, blood-pressure and metabolic control, and social and cognitive engagement. Those fundamentals outperform any supplement. Targeted options — certain peptides, NAD+, or hormone optimization — are considered only after the fundamentals and a medical evaluation, never as a substitute for them.
The Neurology Advantage
This is the part of longevity I was actually trained for. A board-certified neurologist can tell ordinary, age-related change from an early warning sign, screen for what is treatable, and be honest when a symptom needs real medical attention instead of a wellness plan. That judgment is the whole reason to take cognitive longevity to a physician.
Dr. Kamen is board-certified by the American Board of Psychiatry and Neurology and brings a neurology-informed lens to longevity care. That means the nervous system, metabolic health, and hormonal balance are evaluated together rather than in isolation. When brain fog or memory change shows up, the question is not which supplement to sell — it is what is actually causing it. More about Dr. Kamen.
The Mechanisms: NAD+, Neuropeptides, and Sleep
Three mechanisms come up most often when patients ask about cognitive longevity. None of them is a cure. Each is a tool, considered case by case after an evaluation.
- NAD+ and cellular energy— a coenzyme that declines with age and supports the brain’s energy-hungry metabolism. NAD+ is an active area of aging research, and supplementation may support cellular energy, though it is not a treatment for cognitive decline.
- Neuropeptides for focus and stress — including Semax and Selank, originally researched for focus, stress response, and mood. The published evidence is limited and largely non-Western, so these are considered carefully and only when appropriate.
- Sleep and recovery — poor sleep accelerates cognitive symptoms and is often the real cause of brain fog. Sleep quality is evaluated directly, because no peptide compensates for chronic sleep deprivation.
These tools sit on top of the fundamentals, not in place of them. A clinic that leads with peptides before asking about your sleep, thyroid, or blood pressure has the order backwards.
The Cognitive Longevity Evaluation
| Phase | What happens | Physician role |
|---|---|---|
| Evaluation | $88 visit with Dr. Kamen — history, goals, cognitive concerns, medical review | Confirms cognitive longevity care is appropriate and sets testing priorities |
| Labs & screening | Metabolic, hormone, thyroid, inflammatory, and sleep-related panels | Rules out treatable causes of brain fog before any targeted option |
| Personalized plan | Fundamentals first, plus peptides, NAD+, or hormone support where indicated | Every recommendation ties to a specific finding in your labs |
| Follow-up & tracking | Scheduled check-ins and repeat biomarkers over weeks to months | Adjusts the plan based on your measured response |
Individual results vary and are not guaranteed. Cognitive longevity is preventive optimization and complements — it does not replace — your relationship with a primary care physician or neurologist managing a diagnosed condition.

Cognitive Longevity in Las Vegas — FAQ
What is cognitive longevity?
Cognitive longevity is the practice of protecting brain function — memory, focus, processing speed, and mood — as you age, the same way longevity medicine protects metabolic and physical health. It is preventive optimization, not a disease treatment. The brain is one of the first systems to show the effects of aging, so it deserves a dedicated, evidence-based strategy rather than being an afterthought to hormones and IV menus.
Do peptides help brain fog?
They can, but only after the actual cause is found. Brain fog is usually a symptom of something else — poor sleep, stress, thyroid imbalance, hormonal change, anemia, or medication effects. Those deserve a medical evaluation first. Once they are ruled out or treated, certain peptides studied for focus and stress may be considered as targeted support for a specific person. No peptide is FDA-approved to treat brain fog as a medical condition.
Is cognitive longevity care safe?
When it is physician-led and lab-guided, cognitive longevity care is a careful, evidence-based approach to prevention. No therapy is started without an evaluation and baseline labs, and every protocol is monitored against your follow-up results. If something is not appropriate for you, Dr. Kamen will tell you so rather than prescribe it. This is the opposite of ordering untested supplements from a website.
How much does a cognitive longevity evaluation cost in Las Vegas?
Care starts with an $88 physician evaluation with board-certified neurologist Dr. Charles Kamen, MD — applied toward your plan if you continue. From there, cost depends on the labs and protocols appropriate for you. Every line item is reviewed with you in person before you commit. There is no subscription and no hidden markup.
What peptides are studied for brain health?
A small number of neuropeptides have been studied for focus, stress response, and mood. These include compounds originally researched in Russia and Eastern Europe (such as Semax and Selank) with limited large-scale Western trial data. NAD+, a coenzyme that declines with age, is also studied for cellular energy and brain metabolism. None are FDA-approved to treat cognitive decline, and any clinic claiming a peptide reverses brain aging should be treated with skepticism.
How long does it take to see results?
Results vary by individual and depend on what the evaluation finds. If brain fog is driven by a treatable cause like sleep apnea or thyroid disease, correcting that can improve symptoms within weeks. Targeted options, where appropriate, are tracked against your own follow-up data over weeks to months. We measure progress against your baseline rather than relying on how you feel.
Do you offer telehealth for cognitive longevity in Nevada?
Yes. Nevada residents can complete the evaluation and follow-ups by secure telehealth, with labs drawn at a location near you. In-person visits are available at our southeast Las Vegas clinic at Eastern Ave and the 215. Whether you are in Henderson, Summerlin, Green Valley, or anywhere else in Nevada, you can access physician-led cognitive care.
Is cognitive longevity the same as treating dementia?
No, and this distinction matters. Cognitive longevity is optimization and prevention — protecting the brain you have and addressing risk factors early. It is not a treatment or cure for Alzheimer’s disease, dementia, or any neurodegenerative disease. No peptide, IV, or supplement reverses dementia. If memory loss or a clear decline from your baseline is the real concern, the right first step is a neurological evaluation, not a wellness protocol.
Do you see patients in Henderson and Summerlin?
Yes. LiveNow Longevity serves Las Vegas, Henderson, Summerlin, Green Valley, and all of Nevada — in person at our southeast Las Vegas clinic at Eastern Ave and the 215, or by secure telehealth for Nevada residents. If you are searching for a neurologist-led cognitive longevity doctor near you in the Las Vegas valley, start with the $88 evaluation.
Why see a neurologist for brain aging?
A board-certified neurologist is the right specialist for cognitive aging because cognition is a neurological function. A neurologist can distinguish ordinary, age-related changes from early signs of a treatable neurological or systemic condition, knows the relevant biology, and can screen for contraindications. That clinical judgment — knowing when a symptom needs real medical attention versus a wellness protocol — is the difference between responsible cognitive care and selling supplements.
