The World Health Organization (WHO) has dropped a bombshell with its latest report, Dementia in Refugees and Migrants: Epidemiology, Public Health Implications, and Global Health Responses.
Released as the sixth installment in the Global Evidence Review on Health and Migration (GEHM) series, this 146-page exposé reveals a hidden crisis: dementia is silently ravaging displaced populations worldwide.
With over 57 million people already affected by dementia globally and nearly 10 million new cases emerging annually, this neurodegenerative condition ranks as the seventh leading cause of death and a top contributor to disability among older adults.
Yet, for refugees and migrants, the situation is exponentially worse—underscored by systemic neglect, inadequate care, and a glaring lack of data.
As migration surges due to conflict, climate change, poverty, and food insecurity, the number of older refugees and migrants is skyrocketing.
The WHO warns that these vulnerable groups face towering barriers to dementia care, from linguistic and cultural disconnects to disrupted support systems and undertrained healthcare providers.
This report isn’t just a wake-up call—it’s a rallying cry for urgent action to address what experts are calling a “forgotten epidemic” in a world on the move.

Dementia: A Global Health Titan
Dementia isn’t a minor ailment—it’s a colossal public health challenge.
Affecting more than 57 million people worldwide, it claims lives and shatters families, with a staggering economic toll exceeding $1 trillion annually.
The condition, which primarily strikes those over 60, has no cure, though interventions like physical activity, social connection, and certain medications can ease its burden.
But for millions, access to these lifelines remains out of reach, overshadowed by stigma, discrimination, and patchy healthcare systems.
For the general population, dementia is daunting enough.
But for refugees and migrants—uprooted by war, environmental disasters, or economic collapse—the stakes are even higher.
The WHO report paints a grim picture: these groups are grappling with a perfect storm of migration-related stressors, fractured support networks, and health systems ill-equipped to meet their needs.
As the global population ages and displacement accelerates, the intersection of dementia and migration is emerging as a ticking time bomb.
The Plight of Refugees and Migrants with Dementia
Imagine fleeing your home, only to face a new enemy: a disease that erases your memories and strips away your independence.
For refugees and migrants with dementia, this nightmare is all too real.
The WHO report highlights how these individuals encounter towering obstacles to care, from a lack of culturally sensitive diagnostics to a shortage of specialists trained to bridge linguistic and cultural divides.
Underdiagnosis and undertreatment are rampant, leaving countless cases undetected and unaddressed.
Take the numbers: the population of over-60s living outside their birth countries has nearly doubled in three decades, soaring from 25.5 million in 1990 to 48.2 million in 2020.
This surge is especially stark in regions like western Asia (encompassing the Middle East), where a third of the world’s refugees hail from conflict-ravaged nations like Syria and Afghanistan.
As these populations age, dementia’s shadow looms larger—yet health policies and emergency responses remain woefully unprepared.
Dr. Santino Severoni, Director of WHO’s Department of Health and Migration, didn’t mince words: “Dementia care must be woven into the fabric of migration and public health policies.
Refugees and migrants have the same right to health as anyone else, yet they’re consistently sidelined by systemic failures.”
His call to action is clear—timely diagnosis, effective treatment, and robust support systems aren’t luxuries; they’re necessities.
Why Dementia Hits Displaced Populations Harder
Displacement doesn’t just uproot lives—it amplifies dementia’s impact.
The WHO report underscores how migration-related stressors—trauma, poverty, and isolation—compound the disease’s effects.
Add to that a lack of cross-cultural assessment tools and you’ve got a recipe for disaster.
Healthcare providers often lack the training to recognize dementia in diverse populations, leading to missed diagnoses and inadequate care.
Then there’s the data gap.
Research on dementia prevalence and risk factors among refugees and migrants is thin at best, leaving policymakers in the dark.
Without granular, disaggregated data, health systems can’t tailor solutions to these groups’ unique needs.
“We’re flying blind,” experts warn, as the absence of evidence stalls progress on interventions that could save lives and ease suffering.
Dévora Kestel, WHO’s Director of Mental Health, Brain Health, and Substance Use, emphasized the stakes: “Refugees and migrants are already vulnerable. Dementia piles on additional risks, and our health systems aren’t ready. We need emergency responses that actually address these barriers—otherwise, we’re abandoning millions to fend for themselves.”
A Roadmap to Solutions: WHO’s Urgent Call to Action
The WHO isn’t just sounding the alarm—it’s laying out a blueprint for change.
The report synthesizes global evidence and delivers a slew of policy recommendations aimed at governments, health ministries, and program leaders.
Here’s what’s on the table:
1. Policy Overhaul: Embed refugees and migrants in national dementia strategies and broader health frameworks.
No more sidelining these groups—they belong at the center of the conversation.
2. Awareness Blitz: Launch campaigns to spotlight dementia in displaced communities.
Build dementia-friendly spaces, even in chaotic emergency settings, to break down stigma and foster inclusion.
3. Risk Reduction Revolution: Roll out culturally tailored programs to cut dementia risk, from tackling smoking and diabetes to addressing air pollution.
Tie these efforts into wider noncommunicable disease prevention plans and ramp up research on what works.
4. Care Transformation: Tear down barriers to diagnosis and treatment.
Create integrated care pathways and train healthcare workers to serve diverse populations effectively.
5. Carer Lifeline: Equip caregivers—often family members—with training, legal protections, and access to support services.
Involve them in planning and policymaking, especially in crisis zones.
6. Data Power-Up: Bolster health surveillance systems to track dementia in refugees and migrants.
Fill the evidence gaps with robust research to guide smarter interventions.
7. Innovation Surge: Prioritize dementia in displaced populations on the global research stage.
Pump funding and collaboration into solutions that fit their real-world challenges.
These aren’t pie-in-the-sky ideas—they’re actionable steps to drag dementia care out of the shadows and into the 21st century.
The Forgotten Victims of Crisis
“People with dementia are often forgotten in a crisis,” said Jerome Salomon, an assistant WHO director general.
He’s not wrong.
War, poverty, and climate change are pushing millions to flee, and older migrants are increasingly caught in the crosshairs.
The WHO report notes that while some patient registries suggest lower dementia rates among migrants, clinical trials tell a different story—hinting at a massive underdiagnosis crisis.
Marco Canevelli, an expert from Sapienza University in Rome, broke it down at a WHO briefing: “This gap points to poor access to healthcare and a failure to spot cases.
Migrants and refugees don’t just lack resources—they’re battling language barriers, low health literacy, and systems that aren’t built for them.”
Caregivers, too, are stretched thin, juggling limited knowledge, cultural mismatches, and a dearth of support like interpreters or mediators.
The numbers back up the urgency.
Dementia’s global footprint—55 million-plus cases and counting—carries a trillion-dollar price tag.
For migrants, the costs are political as well as economic, often fueling anti-immigrant rhetoric in wealthier nations.
Yet the WHO insists nearly half of cases could be prevented by targeting risk factors—a strategy made tougher when lives are upended by displacement.
A Growing Storm on the Horizon
The WHO report isn’t just a snapshot—it’s a forecast.
Population aging, food insecurity, climate disasters, and conflict are swelling the ranks of refugees and migrants, including those of older age.
“A growing number” of these individuals are living with dementia, the report warns, and host countries aren’t ready.
From emergency camps to urban resettlement zones, the health needs of these populations are being ignored.
“The evidence is clear,” the report states.
“Migration and forced displacement touch every aspect of dementia care—from prevention to treatment to support.”
As the world grapples with this “increasingly evident” crisis, the WHO is pushing for recognition and action.
Health systems must adapt, and fast, or risk leaving millions to fade into oblivion.
Why This Matters Now
This isn’t a distant problem—it’s here, and it’s escalating.
The WHO’s GEHM series, crafted with input from its Health, Migration, and Mental Health departments, isn’t just academic fluff.
It’s a lifeline for policymakers, offering evidence-based insights to tackle the health woes of displaced populations.
Dementia in refugees and migrants isn’t a niche issue—it’s a global health emergency demanding a global response.
As Dr. Severoni put it, “Urgent action isn’t optional—it’s essential.”
Refugees and migrants with dementia aren’t just statistics—they’re people, and they’re being failed.
It’s time to rewrite the narrative, one policy, one diagnosis, one act of care at a time.
