Researchers may have found an unlikely contributor to the development of Alzheimer’s disease: the bacteria in your gut. Their study, published in the journal Science, suggested that certain gut bacteria increase the brain damage seen in mice with an Alzheimer’s-like disease.
In Alzheimer’s disease – the most common form of dementia – proteins build up abnormally in the brain. One of these proteins is called tau, and its build-up causes the death of brain cells that are involved in memory, causing forgetfulness and eventually permanent memory loss.
