It is a very widespread bacteria nestled in the stomach, which could be one of the factors favoring the onset of Alzheimer’s disease. By triggering inflammation of the organ, this infection, if not treated, would increase the risk of contracting this neurodegenerative disease by 11%.

According to Canadian researchers, a very common stomach bacteria could be linked to an increased risk of developing Alzheimer’s disease. Helicobacter pylori. This bacteria, which a third of the population carries, infects the inner lining of the stomach. Acquired mainly during childhood, the infection persists throughout life if left untreated.
The bacteria causes inflammation of the stomach (gastritisgastritis) which generally goes unnoticed. But that’s not all. Because, according to researchers from McGill University in Montreal, whose study is published in the journal Alzheimer’s & Dementia, The Journal of the Alzheimer’s Associationit could also increase the risk of developing Alzheimer’s disease.

In France, 15 to 30% of the population is infected with Helicobacter pylori. The frequency varies according to age groups: less than 20% of people under 30 are infected, more than 50% of people over 50 are infected.
By collecting data from more than four million people over the age of 50, living in the United Kingdom between 1988 and 2019, they observed that infection with H. pylori was associated with an 11% increase in the risk of contracting dementiadementia.
The urgency of finding a treatment
“ The world’s population is aging, so the number of people with dementia is expected to triple in the next 40 yearssays Dr. Paul Brassard, lead author of the study and professor at the Faculty of Medicine at McGill University. Despite these alarming data, we still do not have effective treatments against this disease. “.
The trail of infection Helicobacter pyloriHelicobacter pylori is therefore very important insofar as there is a treatment to get rid of it. It is based on taking several antibioticsantibiotics and a medicine that reduces stomach acid.
