This season of Tiny Expeditions has taken a deep dive into brain health, focusing on how our brains develop, change, and sometimes break down over time. In this final episode, we shift our perspective from treating disease to building wellness.
Our hosts, Chris Powell and Dr. Sarah Sharman, discuss the concept of focusing on healthspan instead of lifespan with Dr. Jennifer Lovejoy from Phenome Health and HudsonAlpha’s Dr. Nick Cochran and Meagan Cochran. You’ll hear how scientists are using genomics, phenomics, and lifestyle data to help people stay healthier, longer, and how a new research project called HOPE‑AD is using that data to bring fresh possibilities to Alzheimer’s prevention.
Join us for Season 6, Episode 5, “From Lifespan to Healthspan: Rethinking Brain Wellness,” and learn how science, technology, and everyday choices can work together to shape the future of healthy aging.
Behind the Scenes
Meet Our Guests
Jennifer Lovejoy, PhD, Chief Translational Science Officer for Phenome Health
In her role, she studies how huge sets of health data (think wearables, lab results, and lifestyle patterns) can help us measure wellness, not just illness.
Nick Cochran, PhD, Faculty Investigator at HudsonAlpha Institute for Biotechnology
His lab studies genomic approaches for the diagnosis and treatment of Alzheimer’s disease and related dementias.
Meagan Cochran, MS, CGC, Director of Clinical Education at HudsonAlpha Institute for Biotechnology; Director of the Smith Family Clinic for Genomic Medicine
She helps connect discoveries from the lab to people and families seeking answers.
Healthspan vs. Lifespan: What’s the Difference?
Most of us want a long life, but the number of candles on our birthday cake isn’t the only goal. Lifespan is simply how long we live. Healthspan is how many of those years we enjoy in good physical and mental health.
Consider the years between feeling your best and the first time a chronic condition begins to limit your activities; that gap is your healthspan. As humans live longer lives, scientists are asking: Can we extend that healthy portion of life even further?
As you’ll hear in the episode, the encouraging news is that research suggests the answer is ‘yes,’ especially when biology meets daily habits.
Genomes, Phenomes, and All the “-omics”
On Tiny Expeditions, we talk a lot about the genome, the DNA that we’re born with. But as we’ve mentioned before, that code doesn’t tell the whole story of who you are or how your health changes over time.
Phenomics brings everything together by examining the traits and characteristics that result from the interaction of genes, proteins, chemicals, environment, and lifestyle factors. Those traits might be simple, such as height or blood pressure, or complex, like cognitive performance or how a person responds to a medication.
With new tools and cheaper technology, researchers can now layer these datasets, along with others such as metabolomics and proteomics, into a comprehensive picture of health.
By tracking thousands of data points—from biomolecules to daily behaviors—scientists can detect subtle shifts that signal when someone’s body is moving away from wellness long before symptoms appear. That early insight could make prevention easier and cheaper than treatment later on.
Lifestyle Matters: A Multimodal Approach to Wellness
We’ve all heard the advice: eat well, move more, and manage stress. In the research world, these aren’t just anecdotes to urge you to be healthier; they’re measurable interventions.
The term “multimodal lifestyle intervention” simply means combining several healthy habits at once: a balanced diet, regular physical activity, cognitive training, social engagement, adequate sleep, and stress reduction. Each small improvement adds up, especially for brain health.
Studies show that people who follow structured, supported programs have better cognitive scores than those trying to go it alone. It turns out that having personalized coaching and accountability really does matter.
The HOPE‑AD Project
At HudsonAlpha, Nick and Meagan Cochran are applying the latest science to the HOPE‑AD study, short for Healthy Outcomes through Phenomic Exploration in Alzheimer’s Disease.
This collaborative effort among HudsonAlpha, Phenome Health, and the Buck Institute for Research on Aging takes a proactive stance toward Alzheimer’s. The project is exploring whether rich biological data, combined with lifestyle coaching, can reduce a person’s risk of Alzheimer’s disease.
Unlike most Alzheimer’s studies that recruit individuals already experiencing cognitive decline, HOPE‑AD focuses on people who are still asymptomatic. Instead of waiting until memory problems appear, participants join while still healthy. Blood samples reveal early molecular clues, wearables monitor daily behavior, and personalized interventions aim to keep the brain resilient for years to come.
Why It Matters
Focusing on healthspan invites a new question: instead of asking “How do we treat disease?” we can ask “How do we stay well?”
From a scientific standpoint, that means building massive, integrated datasets that join genes, molecules, and lifestyles. From a personal standpoint, it means adopting small, consistent habits that help support those biological systems.
