Recent research suggests a connection between a common stomach bacteria, Helicobacter pylori (H. pylori), and an increased risk of Alzheimer’s disease.
This bacterium, found in two-thirds of the world’s population, is known for causing indigestion, gastritis, ulcers, and even stomach cancer. Now, it may also be a factor in the development of Alzheimer’s, the most common form of dementia.
The study, focusing on individuals aged 50 and above, analyzed the health data of over 4 million people in the United Kingdom from 1988 to 2019.
The findings revealed that those with symptomatic H. pylori infection had an 11% higher risk of developing Alzheimer’s disease.
This significant discovery adds to the growing research exploring the role of infections, particularly H. pylori, in Alzheimer’s development.
Alzheimer’s disease, affecting millions globally, is expected to increase dramatically with the aging population.
Paul Brassard, the senior author of the study and a professor at McGill University’s Department of Medicine, emphasizes the urgency of this matter.
“With dementia numbers expected to triple in the next 40 years, we face a lack of effective treatment options for this disease,” he says.
The implications of this study are far-reaching. It opens new avenues for research, particularly investigating whether eradicating H. pylori could help prevent Alzheimer’s in some individuals.
This approach could potentially inform the development of targeted prevention strategies, such as individualized eradication programs, to reduce infections at the population level.
Brassard, also a public health and preventive medicine physician at the McGill University Health Centre, hopes that these findings will shed light on the potential role of H. pylori in dementia.
This could pave the way for innovative prevention methods against Alzheimer’s disease, a condition that continues to challenge healthcare systems and families worldwide.
Published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, this study highlights the importance of understanding the diverse factors contributing to Alzheimer’s disease and the potential for new strategies in its prevention and management.
