To mark World Alzheimer’s Day, we’d like to take a look back at the current state of knowledge about Alzheimer’s disease around the world. We’ll delve into the figures, facts and poignant stories that bear witness to the reality of Alzheimer’s around the world. We will also explore the joint efforts of research, awareness and support for patients and families, as it is essential to break the silence and build a future where Alzheimer’s disease is no longer synonymous with despair, but rather with hope and compassion.


Alzheimer’s, a devastating disease spreading silently around the world, affects millions of people, shattering lives and posing monumental challenges to individuals, families and entire societies. This neurodegenerative disease, characterized by progressive loss of memory, cognition and independence, is one of the most pressing public health epidemics of our time. The figures are alarming, with increasing prevalence as the world’s population ages. However, beyond the raw statistics, Alzheimer’s is above all a human disease, affecting each patient and each loved one in a unique and heartbreaking way. That’s why it’s imperative to understand the scale of this global health problem, to explore the alarming data that reveal the extent of its impact and, above all, to examine the global initiatives in place to tackle it.





Worldwide Alzheimer’s statistics

Alzheimer’s is a silent pandemic affecting millions of lives worldwide. Understanding the scale of this epidemic is essential to guide prevention, research and management efforts. In this section, we dive into global Alzheimer’s statistics, highlighting current and projected figures, as well as the demographic groups most affected.

According to data from the World Health Organization, there are currently 55 million people worldwide suffering from dementia, of whom Alzheimer’s disease accounts for between 60 and 70% of cases. Dementia ranks as the seventh leading cause of death worldwide, underlining its significant impact on global health. The impact of Alzheimer’s disease is not limited to France: worldwide, there are an estimated 46 million cases of neuro-evolutionary disease, with almost 4.6 million new cases every year. According to projections, this figure is set to double every 20 years, reaching over 80 million cases by 2040.


Worldwide prevalence of Alzheimer’s








Current figures show that over 50 million people worldwide suffer from Alzheimer’s disease, and this figure is rising all the time. Forecasts indicate that by 2050, this number could rise to almost 152 million, mainly due to the aging of the world’s population. This alarming growth places Alzheimer’s among the top public health priorities, requiring immediate action to tackle this growing epidemic.

The challenges facing Alzheimer’s

Alzheimer’s is a complex disease that poses major challenges worldwide. Understanding these challenges is essential to guide future efforts in the fight against this devastating disease. In this section, we look at the obstacles to the global management of Alzheimer’s, as well as future prospects for Alzheimer’s research and management.




Barriers to global management

Barriers to prevention, early diagnosis and treatment

Prevention of Alzheimer’s is hampered by a lack of complete understanding of its causes. Although risk factors such as aging, family history and certain genes have been identified, there is as yet no foolproof method of prevention. Moreover, early diagnosis is complicated by the fact that Alzheimer’s symptoms can be confused with other cognitive disorders. Early detection methods such as brain imaging and biomarkers are evolving, but their accessibility remains limited



Alzheimer’s remains a major challenge because of the complexity of early diagnosis. We need more accessible tests and more precise biomarkers to identify the disease at an early stage.
