If the link between Alzheimer’s disease and the intestinal microbiota was studied by scientists, it is now confirmed by a study.
Alzheimer’s disease affects more than 200,000 people each year. Scientists are still trying to understand the origin of the disease to better treat it.
A recent study published in the journal The Journal of Alzheimer Disease confirmed the link between certain bacteria in the gut microbiota and the amount of amyloid plaques (which block communication between neurons, resulting in cell death) in the brain. These elements of the microbiota would be transported to the brain by the blood.
This discovery supports the scientists’ thesis that patients with Alzheimer’s disease have an altered microbiota with less microbial diversity.
Another study published a few months earlier in the Journal of International Medical Research, had also reported the improvement in the state of health of an 82-year-old patient with Alzheimer’s disease and hospitalized for a lung infection after a microbiota transplant, corroborating this thesis of a link between the brain system and intestinal.
The goal is now for researchers to design treatments that can modulate the microbiota of people at risk as part of a preventive treatment.
