True Health and Joy: A Brain-Healthy Path to Flourishing as You Age

“True health isn’t meant to be a burden. It’s meant to create space for joy, for purpose, and connection.”
And here’s a truth I want to say out loud right from the start: “Joy and connection aren’t just nice extras. They’re biologically protective.”
Hi, I’m Dr. Cynthia Libert, and I’m so glad you’re here with me today.
If you’ve been wondering how to protect your memory, keep your mind sharp, and also feel strong, vibrant, and truly flourish as you age—you’re in exactly the right place.
Cognitive decline isn’t “just getting older”
I’ve been in clinical practice for almost 25 years now, and I’ve walked alongside thousands of patients—many of them high achievers: engineers, executives, educators, people who are used to being on top of their game.
And yet, they’ll often quietly confess they’re noticing changes:
- forgetting names
- losing focus mid-sentence
- feeling like their energy and drive just aren’t what they used to be
So hear me clearly:
“These changes are not simply getting older, and cognitive decline is not necessarily inevitable.”
My goal is to help people extend their health span—those years of life spent free of disability and chronic disease. We know from cutting-edge research we can often slow biological aging (the wear and tear on your cells) and as a result keep the brain and body younger for longer.
Your health is like a garden
I like to think about our health as a garden.
Over time, weeds like inflammation, insulin resistance, and hidden toxins start to creep in. If we ignore them, they spread—and the garden becomes overgrown.
That’s when chronic diseases like heart disease, type 2 diabetes, autoimmunity, and even dementia can begin to take root.
But when we notice the weeds early… when we tend the soil, feed it well, and prune what doesn’t belong… the garden thrives season after season.
Your body and brain are the same way.
My own turning point: brain fog in my 30s
I know this not only from my training—but from my own life.
Years ago, I found myself teetering on the edge of burnout: long nights on call at the hospital, three young daughters, constant stress, and far too little sleep.
“It’s scary to have brain fog in your 30s.”
And I realized my body was crying out for help.
In hindsight, I’m grateful for that season of struggle because it set me on a quest. I didn’t want to just barely survive—I wanted to flourish… and heal at a deeper level.
Along my journey I discovered something powerful:
“We can actively change our health trajectory.”
“We can slow the ticking clock on ourselves, quiet the inflammation, and create the conditions for a clear mind and a vibrant body well into our 60s and 70s and beyond.”
The mentors who shaped my approach to brain health
I’ve been blessed with extraordinary mentors who shaped how I care for the brain and the whole person.
I trained with Dr. Dale Bredesen, the pioneer behind the RECODE program for Alzheimer’s prevention, and with Institute for Functional Medicine and their intensive cognitive decline curriculum.
RECODE stands for reversal of cognitive decline, and what I appreciate is this: it’s not “a single pill… or a quick fix.” It’s a comprehensive framework that asks why the brain is struggling in the first place.
“When you identify the specific drivers of cognitive decline for an individual… and address those drivers in a personalized way, the brain often begins to heal.”
I’ve also studied with Dr. Datis Kharrazian on neuroinflammation and the immune-brain connection, earned brain health certification through Dr. Daniel Amen, and spent two years in an advanced fellowship with Dr. James Greenblatt and the team at Psychiatry Redefined.
This work has reminded me: there is always hope. There is always more we can explore to address root causes, balance biochemistry, and nurture the spirit—so healing becomes possible.
And over the years I’ve woven all of this together with my own more feminine perspective, my intuition, my faith, biblical insights, and decades of experience walking alongside real people in the trenches of life.
Because to truly cultivate a vibrant mind and a flourishing life, we have to address the whole person—body, mind, and spirit.
My Three Pillars of Brain and Body Vitality
Now I want to walk you through my three pillars—practical steps you can start today, even if you don’t have access to a functional medicine doctor right now.
Pillar 1: Uncover your risk factors (pull the weeds)
Pillar one is about uncovering what’s getting in the way of your brain health and body vitality.
In my clinic, it begins with carefully listening to someone’s story—not just the last year or two, but reaching back into childhood and even preconception. That’s often where root causes get planted: a head injury from sports, mold exposure from a water-damaged home, chronic stress patterns that became “normal.”
Then we use advanced testing, physical exam—and my philosophy here is simple:
“Test, don’t guess.”
Symptoms don’t give us the full picture. Functional labs, cognitive testing, and sometimes brain imaging help us see what’s going on under the surface—often years before anything shows up on routine bloodwork.
The “subtypes” that organize the puzzle pieces
Dr. Bredesen taught me to think about cognitive decline risk factors in subtypes, and I find this so helpful because it organizes the puzzle pieces in a way that makes sense.
Here are some of the major ones:
- Inflammatory subtype: “a low-grade fire” smoldering for years
- Markers we may look at: hs-CRP, ferritin, homocysteine
- And for brain protection, I like inflammation markers in a truly optimal range—not just “normal.”
- Glycotoxic subtype: how your body handles sugar
- “It’s like bathing your brain in syrup.”
- We pay attention to fasting glucose, hemoglobin A1C, fasting insulin—because “normal” ranges often miss what the brain needs to thrive.
- Trophic / low-support subtype: the brain needs nourishment
- Thyroid hormones, sex hormones (estrogen, progesterone, testosterone, DHEA—these are neuroprotective), vitamin D, B12
- Not just “not deficient,” but truly optimal.
- Toxic subtype: more common than you might think
- Heavy metals like mercury and lead, or mold toxins from water-damaged buildings can interfere with mitochondrial function and signaling.
- Vascular subtype: blood flow is everything
- We look at lipid patterns, triglycerides, HDL, advanced markers like Lp(a) or LDL particle number, and blood pressure.
- Traumatic subtype: past concussions, head injuries, and even emotional/physical trauma
- These may not show up on labs, but they’re an essential part of your story.
When we weave your story, lifestyle, targeted labs, cognitive testing, and sometimes imaging together, we begin to see a map.
And here’s the key:
Conventional lab ranges are designed to catch overt disease. Functional medicine looks for functional ranges—narrower windows that reflect optimal health. That’s where prevention lives.
Pillar 2: Optimize epigenetic inputs (build resilience)
Pillar two is about optimization—and honestly, this is where the fun begins.
Let’s talk epigenetics in plain language:
“Imagine your DNA as the hardware of a computer… and epigenetics as the software.”
You can’t change the hardware, but you can influence the software.
“Every day with every choice you make, you are sending signals to your genes.”
When you eat nutrient-dense food, step into the sunlight, protect your sleep, breathe, pray—you’re flipping genetic switches toward healing and resilience.
Here are simple, powerful actions you can start today:
- Eat the rainbow.
“Deeply colored vegetables, leafy greens, berries”—these polyphenols and antioxidants calm inflammation and signal repair. - Protect your sleep like it’s gold.
“Your brain literally cleans house while you sleep.”
The glymphatic system clears waste, and when you shortchange sleep, toxins accumulate.
“Set a bedtime and guard it fiercely.” - Move your body every single day.
This isn’t about perfection. It’s about sending movement signals that spark BDNF—“like miracle grow” for the brain.
And don’t forget your soul: scripture, meditation, gratitude, journaling, prayer, worship, singing—these “don’t just feel good. They lower cortisol and calm an overactive stress response.”
Stack these small daily actions and you build a brain that’s more adaptable, protected, and capable of flourishing.
Pillar 3: Have fun (joy, mindset, and community)
This pillar surprises some people because it’s not about another lab test or supplement.
It’s about learning to enjoy life again—maybe like you did as a child.
I chose the phrase have fun intentionally, because health work can turn into perfectionism and fear:
Did I eat perfectly?
Did I get eight hours?
Did I do my workout?
And when health becomes rigid rules, we lose sight of why we’re doing this in the first place.
So I’ll say it again:
“True health isn’t meant to be a burden. It’s meant to create space for joy, for purpose, and connection.”
And this matters biologically:
- “Loneliness and chronic stress are some of the most significant risk factors for dementia.”
- People who nurture relationships and cultivate gratitude often have healthier brain structure, more nervous system resilience, and longer health spans.
“Your brain quite literally thrives on joy.”
A practical strategy: habit stacking
This isn’t about overhauling your life overnight (that often leads to burnout). Instead, I encourage habit stacking—linking a new behavior to something you already do.
- While brewing coffee: write down three things you’re grateful for
- After an evening walk: call a friend, or pray with your spouse
And give yourself permission to play again:
- pick up a neglected hobby (painting, gardening)
- join a Bible study group
- schedule sit-down dinners and real connection
“It’s not frivolous. It’s not selfish. It’s actually medicine for your brain and your soul.”
Joyful connection releases oxytocin and dopamine, calms stress hormones, strengthens neural networks, and over time can “rewire your brain toward hope and away from fear.”
The big picture: these three pillars reinforce each other
These pillars don’t stand alone.
When you uncover root causes, optimize biology, and weave joy and connection back into your days—they reinforce each other. This is where transformation takes hold. This is the sweet spot where we often see people stabilizing, slowing decline, and truly flourishing.
And I want you to remember this:
Your brain is resilient. Your story matters. And there is so much hope.
