It often begins subtly—misplaced names, forgotten tasks, small gaps in memory we brush off. But what if these were not just harmless lapses, but early signals in a much longer journey? June marks Alzheimer’s & Brain Awareness Month, traditionally a call to action for elder care and late-life planning. Yet, emerging research suggests the story starts much earlier—and that’s precisely why family enterprise leaders, especially the next generation, need to pay attention.
Most next-gens in family businesses are navigating their peak years of learning, identity formation, and strategic decision-making—usually in their 20s to early 40s. At the same time, they are under considerable pressure: to lead with clarity, to preserve legacies, to innovate with intention. What if the seeds of future cognitive vulnerability are being sown now? And what if understanding them could change how families plan for continuity, governance, and well-being?
To deepen this conversation, we are featuring an interview with Dr. James Noble, Assistant Professor of Neurology at Columbia University Medical Center, who offers a vital insight: “About half of all people with Alzheimer’s don’t recognize that they have a problem with memory or thinking.” This lack of awareness—what clinicians call anosognosia—makes early detection especially difficult and underscores why families need to cultivate not just vigilance, but systemic care and shared responsibility.
This month, we reframe Alzheimer’s disease not only as a medical issue for aging parents but as a systemic, life-course challenge for enterprising families. From leadership readiness to succession resilience, it’s time we include brain health in the family enterprise conversation—long before symptoms show up.
Research Connection
A groundbreaking study published in The Lancet Regional Health – Americas (2025) reveals that Alzheimer’s disease (AD) risk factors are not just a concern for late life—they affect cognitive performance as early as ages 24–44. Drawing on data from over 11,000 participants in the Add Health study, researchers analyzed a range of biological and lifestyle markers that may silently shape cognitive function decades before symptoms of dementia appear.
Their findings challenge the conventional timeline:
- Cardiovascular risk (measured by the CAIDE score) was associated with poorer working memory in adults as young as 24. Each incremental increase in risk—e.g., higher cholesterol, lower physical activity—had a measurable impact on performance in basic cognitive tasks like backward digit span.
- Neurodegenerative markers like Tau were significantly associated with diminished immediate recall in adults aged 34–44, indicating that even early signs of memory decline can be biologically detected long before clinical diagnosis.
- Inflammatory biomarkers—particularly IL-6, IL-8, and IL-1β—were also linked to lower scores in all cognitive domains, with stronger associations emerging in participants' late 30s.
Strikingly, the commonly discussed genetic marker APOE ε4 showed no correlation with cognitive function at these early ages. In other words, family history alone may not be the most relevant early warning sign. Lifestyle and inflammatory markers may be more predictive—and actionable.
The implications are profound. Cognitive health is not simply an eldercare issue. It’s a leadership issue, a continuity issue, and increasingly, a next-gen issue.
Relevance to Family Enterprises
If your family is investing in leadership development, succession planning, or continuity strategies, this research should serve as a wake-up call. Here’s why:
- Leadership Resilience Starts Young
Next-gens are expected to carry decision-making responsibility for decades. Integrating cognitive health awareness into early leadership journeys—via annual wellness checks, stress-reduction protocols, or executive health screenings—adds an essential layer of resilience. - Rethinking 'Readiness'
We often define succession readiness by age, education, or experience. But what if cognitive capacity—affected silently by cardiovascular and inflammatory risks—was part of the equation? Monitoring these markers can help families support long-term capability, not just immediate readiness. - A Family Wellness Strategy, Not Just a Policy
Enterprising families already invest in financial diversification and governance structures. It’s time to invest similarly in cognitive longevity. Encouraging healthy habits, addressing chronic inflammation, and including cognitive markers in family office wellness protocols could be a strategic differentiator.
Imagine a future where the next-gen not only inherits wealth and responsibility—but also the awareness and tools to protect the very cognitive functions that enable them to lead wisely.
Reflection Questions
- As a family enterprise, do we think about leadership health primarily in terms of burnout and stress—or also in terms of long-term cognitive resilience?
- What assumptions do we hold about when “Alzheimer’s risk” begins—and how might these assumptions blind us to early action?
- Could we be overlooking low-cost, high-impact ways to integrate cognitive health awareness into our leadership development efforts?
- How might we encourage the next generation to think about their own health—not just as a personal matter, but as a component of enterprise continuity?
- What would it look like to design a wellness strategy that spans generations and supports both individual and organizational longevity?
More to come on how families can begin navigating these complex and often sensitive conversations—about health, capacity, and long-term responsibility—with care, clarity, and courage.
