Probiotics and Alzheimer’s disease
This is the first study to show a direct link between gut bacteria and Alzheimer’s disease (AD). In the lab, doctors found mice with AD had different gut bacteria compared to those that were healthy. A third group had no gut bacteria, and had significantly less beta-amyloid plaques in the brain, a major factor in AD. Doctors transferred gut bacteria from the AD group to half the no-bacteria group, and bacteria from the healthy group to the other half. The no-bacteria group that got the AD gut bacteria developed more beta-amyloid plaques than those that got gut bacteria from the healthy group.
