According to a recent study, certain stomach bacteria may increase the risk of developing Alzheimer’s disease. A discovery that could help combat this pathology.
According to 2017 data from the High Authority for Health, 15 to 30% of the population would be affected Helicobacter pylori. As a reminder, these are bacteria in the stomach that can cause indigestion, gastritis, stomach ulcers and even stomach cancer. But that’s not all ! This emerges from a recent study carried out by a team at McGill University and published in the journal Alzheimer’s and Dementia, The Journal of the Alzheimer’s Association, The bacteria could also increase the risk of developing it Alzheimer. Before reaching this conclusion, experts looked for links between infections a person has had throughout their life and the development of the most well-known dementia.
These stomach bacteria can increase the risk of Alzheimer’s disease
As part of the study, scientists analyzed the health data of more than 4 million people aged 50 and over in the UK between 1988 and 2019. The researchers quickly discovered this Test subjects infected with Helicobacter pylori were 11% more likely to develop Alzheimer’s disease. “This is a modest increase, but it is statistically significant because it was found in a large population.”says the study’s lead author, Paul Brassard, a public health and preventive medicine specialist at McGill University Health Center (MUHC). According to experts, the bacteria could trigger an inflammatory process that would promote the deposition of amyloid plaques in the brain. A characteristic phenomenon of Alzheimer’s disease.
Helicobacter pylor: decreasing risk after an infection of more than ten years
Obviously, the risk of developing Alzheimer’s disease due to the bacteria varies depending on several factors. This is necessary first of all Helicobacter pylori causes symptoms such as indigestion, heartburn, ulcers or stomach cancer, so it has a real impact on the brain and therefore dementia. Finally, the scientists explain in their study that the risk varies over time. Ten years after the clinical manifestation of an infection with Helicobacter pylorithe risk decreases. “This may mean that a decade is the time needed to trigger an inflammatory process [notamment neuro-inflammatoire néfaste] or erosion of the stomach lining, which would significantly impair the absorption of vitamin 12, the deficiency of which is linked to dementia.concludes Paul Brassard.
