Brain Capital: From Davos to the Clinic

This week in Davos, while world leaders are gathering to discuss AI, geopolitics, and economic uncertainty, a different conversation is gaining momentum—one that will shape how we work, age, and compete for decades to come.

The World Economic Forum and McKinsey Health Institute have released a landmark report titled The Human Advantage: Stronger Brains in the Age of AI. Simultaneously, leaders including physician-neuroscientist Harris Eyre are convening at Rice University's delegation at Davos to advance the brain economy agenda—an effort projected to boost the global economy by as much as $6.2 trillion by 2050.

The central premise is deceptively simple: our brains are our most valuable form of capital, and we're dramatically underinvesting in them.

Brain capital is now positioned as "critical infrastructure"—as foundational to prosperity as roads and data centers. The Brookings Institution has framed it as both an economic AND national security asset. Nations that fail to invest, the WEF report warns, risk "slower growth and being left behind in the next era of the global economy."

My clinical work places me at a unique vantage point on this issue. In addiction medicine, I witness brain capital being actively destroyed. In geriatric psychiatry, I see the consequences when it hasn't been protected across a lifetime. And increasingly, I'm focused on what we can do to preserve it—before the damage is done.

Let’s translate the policy language into clinical terms.

The WEF defines brain health as "a state of optimal brain functioning, supported by the promotion of healthy brain development and the prevention or treatment of mental, neurological and substance use disorders in people of all ages." Brain skills are the cognitive, interpersonal, and adaptive abilities that enable us to contribute meaningfully throughout life.

These elements are naturally paired. You can't develop resilience and creativity if your brain is compromised by untreated depression, unaddressed addiction, or progressive neurodegeneration.

The numbers are sobering:

We know what works. We're simply not investing in it.

Here's what gives me hope: brain capital is not fixed. We can alter the physical makeup of our brains through learning, behavioral change, and addressing root causes of dysfunction.

This connects to what I call Psychiatry 3.0—the evolution from talk therapy (1.0) to neurotransmitter-focused treatments (2.0) to our current understanding of circuit-based neuroscience, systems biology and precision medicine (3.0). The brain is a dynamic resource requiring ongoing investment.

The WEF report outlines five strategic levers:

1. Safeguard brain health through prevention and treatment across the life course. Notably, 85% of stroke's global health impact is linked to modifiable risk factors.

2. Foster brain skills across generations. Half of all mental health conditions appear by the age of 14, and three-quarters by the age of 24. Meanwhile, 59% of employees will need upskilling by 2030.

3. Study brain capital as an interdisciplinary field—developing robust biomarkers and measurement tools. The Global Brain Capital Dashboard already tracks over 100 countries.

4. Invest in brain capital through innovative financing—social impact bonds, public-private partnerships.

5. Mobilize for brain capital through coordinated global action, including the Davos Alzheimer's Collaborative.

In my work at Enterhealth, I treat patients with substance use disorders—brain capital being actively eroded in real-time.

Addiction compromises the prefrontal cortex, impairing decision-making and impulse control. Reward circuitry gets hijacked. Cognitive flexibility decreases. The cascade extends beyond the individual—depleting the brain capital of families, workplaces, and communities.

Neuroplasticity offers genuine hope for recovery, but it requires significant investment. This is why prevention matters so much.

Here's something often missed: substance use disorders are explicitly included in the WEF's definition of brain health conditions, yet addiction remains chronically underfunded and stigmatized. The brain capital framework offers a new way to advocate for appropriate investment. This isn't a moral failing—it's a brain health emergency.

At The Noesis Clinic, I care for patients with dementia and their families. Over 55 million people live with dementia globally. Cases increased 160% over three decades. Two-thirds of Alzheimer's patients are women.

What we're losing goes beyond memory—it's independence, creativity, identity, the ability to connect with loved ones.

But here's where it gets interesting. Increasingly, I'm seeing the adult children of my dementia patients. They've watched their parents decline and they're asking: What can I do NOW to protect my own brain health?

This is brain capital thinking in action—moving from reactive treatment to proactive preservation.

My training in Functional & Integrative Psychiatry has deepened my conviction that we need to shift from reactive to proactive care.

Root-cause approaches align naturally with brain capital thinking: addressing mitochondrial dysfunction, optimizing the gut-brain axis, metabolic approaches to psychiatric conditions, reducing environmental toxin exposure.

The goal isn't simply longevity—it's healthspan. Maintaining cognitive vitality and meaningful engagement throughout life.

And yet, despite advances in precision medicine, the most important diagnostic tool hasn't changed: the story our patient tells us. The art of understanding remains central.

The WEF provides frameworks. Patients need implementation now.

There's an uncomfortable irony in all of this.

We're asking clinicians to assess patients' brain capital, screen for modifiable risk factors, address addiction as an emergency, and have proactive conversations about prevention. But the clinicians we're entrusting with this work are themselves experiencing unprecedented brain capital depletion.

The WEF report notes that more than one in five employees globally experience burn-out symptoms. In healthcare, the numbers are worse. Physicians, nurses, and mental health professionals report burnout rates exceeding 50% in many surveys. Depression, anxiety, and suicidal ideation among healthcare workers have surged since the pandemic—and haven't recovered. The Dr. Lorna Breen Heroes Foundation exists because we lost an extraordinary physician to suicide during COVID—and she was far from alone.

If we're serious about building brain capital at scale, we have to invest in the brain health of those doing the building. Healthcare systems that burn through their workforce aren't just creating a staffing problem—they're depleting the very human infrastructure needed to address the $6.2 trillion opportunity the WEF describes.

For healthcare leaders: You cannot build brain capital with burned-out clinicians. Sustainable scheduling, mental health support, reduced administrative burden, and genuine autonomy aren't perks—they're prerequisites.

The question "who heals the healers?" isn't rhetorical. It demands an answer.

The WEF report frames this as "The Human Advantage" for a reason. AI makes brain skills more valuable, not less.

The skills AI cannot replace—empathy, complex ethical reasoning, adaptability, therapeutic relationship, clinical intuition—all depend on healthy, well-functioning brains.

The investment case is compelling: 59% of workers will need new skills by 2030, but brain health is the prerequisite for learning. Proactive employee brain health investment could increase global GDP by 12%, generating $11.7 trillion in economic value.

The question isn't whether we can afford to invest in brain capital. It's whether we can afford not to.

The conversations at Davos this week represent a watershed moment. But the real work happens in clinics, in communities, in families making daily choices. That's where brain capital is actually built—or lost.

The mission of Psychiatry 3.0 continues: bridging traditional psychiatry with emerging, evidence-based approaches—without losing the art of understanding at the center. The science is advancing. The training is catching up. And the opportunity to do better for our patients has never been greater.
