Prince Harry and Meghan Markle’s surprise move spotlights a major longevity tool
Prince Harry and Meghan Markle’s return to the United Kingdom puts the royal family back within reach after 6 years in California.
The couple returned with their children, Archie and Lilibet, who are set to begin school, creating more opportunity for family contact and a sense of local belonging.[]
For physicians, the more interesting story is not the relocation itself, but what it represents: Regular, meaningful human connection may be one of the most overlooked tools in a dementia-prevention plan.
Living closer to family is not a prescription for longevity. Still, the decision offers a timely hook for discussing why patients’ social worlds, not just their cholesterol levels and step counts, deserve attention in brain-health counseling.
“There’s a quote that says, ‘Connection is medicine for the aging brain,’ and we know that people who are isolated have a tendency to have a faster cognitive decline, increased risk of Alzheimer's, dementia and other dementias, as well as reduced brain stimulation and problem-solving engagement,” Sequita Richardson, MD, a family physician with CenterWell Senior Primary Care, told the American Medical Association.[]
Proximity to family doesn't always equal social connection
A patient can live alone and feel well supported. Another can share a home with relatives and still be lonely. Social isolation refers to limited contact with others, while loneliness is the subjective feeling of being disconnected; both are associated with higher dementia risk.[]
When counseling an older adult about dementia risk, how often do you assess social connection or loneliness?
A systematic review and meta-analysis found that living alone was associated with a 30% higher risk of incident dementia, though living arrangement is only one imperfect proxy for social isolation.[] It may capture not only less day-to-day interaction, but also fewer opportunities for others to notice subtle cognitive, functional, mood, hearing, or mobility changes.
That distinction matters in the exam room. Rather than asking only, “Do you live alone?” clinicians can ask:
“Who do you see or speak with in a typical week?”
“Who would notice if something changed?”
“What gets you out of the house?”
Social contact may build cognitive reserve
The biological pathway is not fully settled, and much of the evidence is observational. Still, social interaction plausibly supports cognitive reserve by repeatedly engaging language, memory, attention, executive function, and emotional processing. It may also reinforce the health behaviors that protect brain and vascular health: movement, adherence, healthier meals, less stress, and timely care-seeking.
The practical takeaway extends beyond family geography. Encourage patients to cultivate a network, not merely a household.
A weekly coffee, group exercise class, choir, adult-learning program, volunteer role, or regular video call can be more attainable than relocation and may provide the consistency that matters.

Social connection should complement, not compete with, established risk-reduction strategies. In UK Biobank research, adults with a family history of dementia who followed at least three healthy lifestyle behaviors had a 25% to 35% lower dementia risk than those following two or fewer behaviors.[] The study was observational, but its message is useful: Family history raises risk; it does not make prevention counseling futile.
Harry and Meghan’s move may be about family, schooling, and belonging, not longevity. But for clinicians, it is a timely reminder that the preventive plan for dementia should include one question patients may not expect: Who is in your life, and how often are you truly connected?
