Изменения в микробиоме кишечника могут появляться за годы до симптомов болезни Альцгеймера

Новое исследование показывает, что изменения в микробиоме кишечника могут начинаться за годы до появления симптомов болезни Альцгеймера. Исследователи сравнили кишечные бактерии у людей с ранней стадией Альцгеймера, людей с легкими

Gut microbiome changes may appear years before Alzheimer's symptoms

A new study finds that changes in the gut microbiome may begin years before Alzheimer's disease symptoms appear. Researchers compared gut bacteria in people with early Alzheimer's, people with mild memory problems, and healthy controls, and found consistent differences. Certain bacterial strains were more common in people who later developed the disease, while others were depleted. The changes are linked to inflammation, which is believed to play a role in Alzheimer's. The findings could lead to a simple stool test that flags risk years in advance, giving families and doctors more time to plan and act. The authors say the work needs confirmation in larger studies but raises the possibility of much earlier detection and new ways to intervene.
