Who is Dr. Tommy Wood?
Dr. Tommy Wood is a neuroscientist, physician, author, and performance consultant whose work focuses on how the brain develops, adapts, recovers, and stays resilient across a lifetime. He trained across three leading European universities — a bachelor's degree in biochemistry from the University of Cambridge, a medical degree from the University of Oxford, and a PhD in physiology and neuroscience from the University of Oslo — and now runs a laboratory at the University of Washington studying brain health across the lifespan, including neuroprotective approaches for the injured developing brain. Alongside his academic career, he has spent more than a decade advising high-performance athletes, including Olympians, world champions, and Formula 1 drivers.
His 2026 book, The Stimulated Mind, lays out a practical framework for lifelong brain health built around what the brain needs to thrive: meaningful stimulation, adequate physiological supply, and the support systems that enable recovery and adaptation.
What does Dr. Wood do at BetterBrain?
At BetterBrain, Dr. Wood leads the science function and advises on the science behind BetterBrain’s prevention programs, including the biomarkers and cognitive assessments BetterBrain tests and how the brain health program works end to end. He helps translate evolving research into clear, evidence-informed approaches that people can use to protect cognitive health and function at their best.

Frequently asked questions
Are Alzheimer's disease and other dementias preventable?
While there is no cure for Alzheimer's disease, the science around prevention has progressed tremendously over the past few years, as detailed in our Science section. A landmark study suggested that ~40% of cases are preventable, but many experts believe this might be closer to 60% given they did not consider important factors such as sleep, hyperhomocysteinemia, among others. What's more, implementing these brain health strategies has clear short term cognitive benefits (25% improvement per the landmark FINGER study) and improves many other aspects of your health.
What are some things I can do to reduce my risk of developing dementia?
While it may not be satisfying, the reality is that "it depends". There are 100+ potential interventions, but to find the 3-5 most effective ones it is critical to understand your biology — hence why BetterBrain does extensive blood biomarker testing among other assessments.
How do you keep my health information safe?
We know your health data is some of your most valuable information. That's why we hold a high bar for data privacy and security, and composed a team of experienced leaders who have built secure data systems in the past:
- One of our co-founders built a secure healthcare platform containing data from over 140M Americans and 7 of the largest health systems in the country
- Our chief engineer built the data infrastructure that housed 15% of all COVID test results in the US, including for members of congress and the Department of Defense. Through his work with electronic health record companies, he ensured the security of ~10% of the US population's healthcare data.
All of BetterBrain's staff are trained on HIPAA regulations, and we use these experts' technical knowledge to constantly enhance our digital, physical, and administrative security measures.

Is BetterBrain right for me?
BetterBrain was designed for anyone interested in improving their brain health — both reducing dementia risk and improving cognitive function. We find that people who benefit the most typically have (1) a family history of dementia / Alzheimer's, OR (2) 1 or 2 copies of the APOE4 gene, OR (3) have been experiencing some level of cognitive decline they would like to address.
I already have my own doctor, how does BetterBrain fit in?
BetterBrain aims to integrate seamlessly into your existing care and help you navigate the broader healthcare system. We do not intend to replace the work of your physician and believe it is important for all to maintain a relationship with a primary care doctor and/or a neurologist.
Does BetterBrain diagnose Alzheimer's or other dementias?
Although BetterBrain can help you unlock a wealth of data about your health and biology, we do not diagnose any conditions. In other words, BetterBrain is not a substitute to medical care. Instead, we encourage to you use the information you learn through BetterBrain to have a thoughtful discussion with your physician to receive any diagnoses and come up with a clinical path forward.
I get lab tests every year at my annual physical. How is this different?
BetterBrain's battery of tests is completely different than what primary care physicians typically order. Our panel has been carefully assembled and vetted by leading physicians to provide a comprehensive view of your brain health. Unfortunately, many of these tests are inaccessible to most people given doctors are typically less focused on long term prevention, and require "medical necessity" for insurance coverage which usually requires existing symptoms.
What tests do you perform?
One of the first steps in your BetterBrain journey is to get a series of tests to help you identify your brain health risks. The tests included in your membership fall under two categories.
Cognitive assessments
Our battery of cognitive tests is designed to give you quick insights on different types of brain abilities - memory, reasoning, concentration, and verbal abilities. These tests have been designed based off 30+ years of research an are used by over 10,000 providers around the world. You can read more about our cognitive testing on our testing partner's website.
Blood tests
Our panel of cross-specialty physicians assembled a set of 54 biomarkers that are the most important to understand for your brain health. We test all of these markers in your initial blood panel, and you can ask us any time about re-testing.

Although there are many more tests you can do that are relevant to your brain health, they are often more expensive and more targeted. BetterBrain can help you access deeper testing at a discounted fee.
Please note that pTau-217 and APOE genetic testing are not currently available in NY, NJ or RI.

How soon after joining can I get tested?
Typically within a few days. As soon as you're signed up, you can schedule your blood draw at any of 5,000+ Quest locations nationwide (or BioReference labs in NY, NJ, RI). We also offer at-home blood draws in most urban areas for an additional $50. You can complete your cognitive assessment and health profile immediately after signing up.
How long after testing will I get my results?
Your bloodwork will typically be available within a week of your blood draw. Once ready, you will recieve an email to view your results directly on our platform.
Who will have access to my results?
We restrict access to results on a need-to-know basis. Namely, your results are available only to you, the ordering physician (who will contact you directly for any critical results), and your brain health expert if you are receiving coaching. Besides that, nobody has access to your health data.
Can I delete my data?
Yes you can. BetterBrain exists to help you identify and understand your health data. We know that this is some of the most important information you have, and it is 100% yours - and nobody else's.
You can delete your data anytime you like by sending us an email at contact@betterbrain.com. Please know that we delete your data permanently. Once it's gone, we will not be able to get it back if you change your mind.

What time commitment does BetterBrain require?
Blueprint: Our entire assessment process typically takes under an hour (~15 min for at-home blood test (longer if you are going to a local lab), <15 min for cognitive assessment, and <10 min for the health profile). However, the real work starts post-assessment. While many interventions are quick and easy (e.g., new supplement routine), others may require more effort (e.g., optimizing sleep). That said, we work hard to ensure you find things that are enjoyable and beneficial to many other aspects of your life.
Coaching Program: The initial assessment takes under an hour, plus regular coaching sessions (weekly or as needed) for 12 weeks. Sessions focus on sustainable lifestyle changes with your dedicated brain health coach. The program is designed to fit into your life with practical, achievable steps toward long-term brain health improvement.
