In a groundbreaking development, experts predict that revolutionary new drugs could herald a “new era” in the global fight against Alzheimer’s disease and dementia. These medical breakthroughs offer hope to the estimated 50 million people living with dementia worldwide, more than two-thirds of whom reside in low- and middle-income countries.
Game-Changing Alzheimer’s Treatments on the Horizon
According to Professor Jeff Cummings, an authority on brain science and health at the University of Nevada, scientific advances are on the cusp of producing medicines that could dramatically change the course of Alzheimer’s disease. “We are truly in a new era,” Cummings enthused. “We have opened the door to understanding and manipulating the biology of Alzheimer’s disease for the benefit of our patients.”
The approval of Eisai and Biogen’s lecanemab and Eli Lilly’s donanemab by medicine watchdogs in many Western countries in 2024 marked a significant milestone. These drugs, which prompt the body to remove amyloid plaque in the brain, have been shown to slow cognitive decline by about 30%.
Overcoming Barriers to Global Access
While the high cost and advanced technology requirements of these newly approved drugs currently limit their widespread availability, especially in lower-income regions, experts believe they pave the way for more accessible treatments in the future. Cummings emphasized that the knowledge gained from these breakthroughs “is going to open the door to new therapies of many types, and those drugs can be exported around the world.”
One promising development is the potential use of blood tests for diagnosing Alzheimer’s, which could replace expensive brain scans. Additionally, trial results suggest that the new drugs could be delivered via subcutaneous injection, enabling at-home administration by caregivers. Looking further ahead, researchers are working on developing oral medications that could be taken daily.
Ultimately, we want oral medications, some pills that can be taken once a day.

Towards Prevention and a Potential Cure
Beyond treatment, experts believe that targeting key risk factors such as smoking, alcohol consumption, and air pollution could prevent up to 40% of Alzheimer’s cases. Cummings expressed optimism about the prospect of controlling the processes that initiate the disease, thereby preventing its development altogether.
- Almost half of dementia cases could potentially be prevented or delayed by addressing modifiable risk factors
- Manipulating the biology of Alzheimer’s onset could control the disease-initiating processes
Democratizing Dementia Care Globally
To truly make an impact on a global scale, experts emphasize the need for increased involvement of low- and middle-income countries in clinical trials. This would not only expand knowledge of how the drugs work among diverse populations but also boost scientific capacity and understanding of dementia in these regions.
When I speak to health ministries in some poorer countries, they tell me they don’t have dementia in their country, which of course, is not true.
– Paola Barbarino, CEO of Alzheimer’s Disease International
Barbarino stresses that alongside scientific progress, attitudes towards dementia must change, particularly in under-resourced nations. Acknowledging the presence of the disease is a crucial first step in addressing it effectively.
As the world stands on the brink of a transformative shift in the battle against Alzheimer’s, these breakthrough treatments offer a beacon of hope for millions of individuals and families affected by dementia. While challenges remain in ensuring equitable access and affordability, the tireless efforts of researchers and advocates bring us closer to a future where the devastating impact of this disease could be significantly diminished, if not eliminated entirely. The dawn of a new era in dementia care is upon us, promising a brighter tomorrow for all.
