1. Global panorama of Alzheimer's disease: a silent epidemic
Alzheimer's disease knows no borders. It strikes all populations, all continents, with significant regional variations that reflect global socio-economic, cultural, and health disparities. This section presents a comprehensive overview of the current situation.
Global statistics reveal an alarming increase in the prevalence of the disease. By 2026, it is estimated that 55 million people will be living with dementia worldwide, of which 60 to 70% specifically suffer from Alzheimer's disease. This constant increase is primarily explained by the global demographic aging and the improvement in life expectancy.
The geographical impact of the disease presents significant disparities. High-income countries, historically the most affected in terms of prevalence, are now seeing developing nations catch up with these worrying figures. This evolution is accompanied by specific challenges in terms of diagnosis, care, and access to treatment.
Global geographic distribution
Asia-Pacific: 60% of global cases, with China and India leading in absolute numbers. The region is experiencing the fastest growth due to accelerated demographic aging.
Europe: 25% of cases, with healthcare systems generally better equipped for early diagnosis and management.
Americas: 12% of cases, with significant disparities between developed and developing countries.
Africa: 3% of current cases, but projected to increase by 300% by 2050.
Key points of the global situation
- One person develops dementia every 3 seconds worldwide
- Women represent 65% of Alzheimer's cases
- Only 25% of affected individuals receive a formal diagnosis
- The global cost exceeds that of cancer and heart diseases combined
- 75% of family caregivers are women
Regular cognitive stimulation can delay the onset of symptoms by 2 to 5 years according to several longitudinal studies. This is why applications like COCO THINKS and COCO MOVES play an important preventive role in this comprehensive approach.
2. Demographic analysis: who is affected and why?
Alzheimer's disease presents distinct demographic profiles that help better understand risk factors and vulnerable populations. Age remains the main non-modifiable risk factor, with a prevalence that approximately doubles every five years after age 65.
Beyond age, several demographic factors significantly influence the risk of developing the disease. Gender is an important factor, with women at increased risk, partially explained by their higher life expectancy and hormonal changes related to menopause.
Socio-economic disparities also play a crucial role in the prevalence and progression of the disease. Populations with lower education levels, modest incomes, or limited access to healthcare generally have higher rates and later diagnoses.
Our research shows that regular cognitive stimulation can be a significant protective factor against cognitive decline. Engaging in varied cognitive activities tailored to individual levels helps strengthen cognitive reserve.
Cognitive reserve develops throughout life through education, professional activity, intellectual hobbies, and social stimulation. The greater this reserve, the more the brain can compensate for damage related to Alzheimer's disease.
Detailed demographic profile
Age: 5% of cases before 65 years, 10-15% between 65-74 years, 44% after 85 years
Gender: 65% women, 35% men among diagnosed individuals
Education: Risk inversely proportional to the level of education
Geography: Significant variations by region and access to care
3. Global economic impact: the cost of forgetting
The economic impact of Alzheimer's disease far exceeds the medical framework to become a major societal issue. In 2026, the global annual cost of dementia is estimated to exceed 1,300 billion euros, representing 1.1% of global GDP and surpassing the valuation of the largest global companies.
This financial burden is unevenly distributed among different stakeholders. Families bear nearly 70% of total costs in developing countries, while in developed countries, public health systems and insurance cover a larger share. This disparity reflects inequalities in access to formal health services.
Direct costs include medical care, hospitalizations, medications, and support services. Indirect costs, often underestimated, include the loss of productivity of family caregivers, professional absenteeism, and the impact on the local economy. Intangible costs, difficult to quantify but real, encompass psychological suffering and loss of quality of life.
Distribution of global costs
- Informal care (family/relatives): 45% of total cost
- Direct medical care: 35% of total cost
- Formal social care: 20% of total cost
- Average cost per patient: €23,500 per year (developed countries)
- Average cost per patient: €3,500 per year (developing countries)
Investing in prevention and early cognitive stimulation could reduce future costs by 30 to 50%. Cognitive stimulation programs like COCO represent a long-term cost-effective investment for healthcare systems.

10. Global prevention: population and individual strategies
The prevention of Alzheimer's disease emerges as a global priority, driven by the accumulation of scientific evidence demonstrating the modifiability of many risk factors. The preventive approach revolves around population strategies aimed at reducing overall incidence and individual interventions targeting high-risk individuals.
Population strategies rely on modifying the social determinants of health: improving access to education, promoting healthy eating, encouraging physical activity, reducing air pollution, and combating social isolation. These "upstream" approaches aim to create environments conducive to cognitive health.
Individual interventions focus on modifying the modifiable risk factors identified by research: high blood pressure, diabetes, obesity, smoking, depression, physical inactivity, and social isolation. Multidisciplinary programs combining medical, nutritional, physical, and cognitive interventions show promising results.
Modifiable risk factors
Cardiovascular factors: Hypertension, diabetes, obesity - optimal medical management
Behavioral factors: Smoking, sedentary lifestyle, diet - lifestyle habit modification
Psychosocial factors: Depression, isolation, stress - psychological and social support
Cognitive factors: Intellectual inactivity - regular cognitive stimulation
Our preventive approach with COCO THINKS and COCO MOVES fits into this global prevention strategy, offering accessible tools to maintain cognitive health throughout life.
We develop adaptive preventive programs that adjust to individual risk profiles, combining cognitive exercises, virtual physical activity, and progress tracking for optimal prevention.
11. Family Caregivers: International Support and Resources
Family caregivers are the backbone of the global care for Alzheimer's disease, representing an estimated informal care force of over 100 million people worldwide. This population of caregivers faces significant challenges: emotional burden, impact on physical and mental health, financial constraints, and social isolation.
International initiatives supporting caregivers are multiplying, recognizing their essential role and specific needs. These programs combine training, psychological support, respite, and technological resources to improve the quality of life for caregivers and, by extension, for the people they support.
The global demographic evolution, with the reduction in family size and geographical distance, is transforming the landscape of family assistance. This evolution requires the development of new support models integrating digital technologies, community services, and expanded solidarity networks.
Global Challenges for Caregivers
- Average care burden: 4-6 hours per day
- Economic impact: loss of income of 30 to 50%
- Mental health: 40% show depressive symptoms
- Social isolation: 60% reduction in social activities
- Physical exhaustion: sleep disorders in 80%
Cognitive stimulation technologies like COCO also provide benefits to caregivers by structuring daily activities, reducing problematic behaviors, and creating positive sharing moments.
12. Future perspectives: towards an inclusive and caring society
The future of the global fight against Alzheimer's is shaped around profound societal transformations aimed at creating inclusive and caring communities for people with dementia. This vision goes beyond the medical framework to embrace a holistic approach to cognitive health and social well-being.
"Dementia-friendly communities" are emerging as a promising model, transforming the social environment to facilitate the participation and inclusion of affected individuals. These community initiatives involve merchants, public transport, municipal services, and citizens in a collective effort of adaptation and support.
The integration of emerging technologies (artificial intelligence, virtual reality, biotechnology) with traditional preventive and therapeutic approaches opens up unprecedented perspectives. This technological and human convergence could revolutionize the prevention, diagnosis, and support of Alzheimer's disease in the coming decades.
