Microbial connection to Alzheimer’s explored
Scientists have long puzzled over the root causes of Alzheimer’s disease, a devastating and typically fatal condition that currently denies more than five million Americans their cognition and memory. But in a provocative editorial soon to be published in the Journal of Alzheimer’s Disease, a cadre of scientists argue that the complex disease may have a surprisingly simple trigger: tiny brain-infecting microbes. This controversial view, which is not new, has long been dismissed as outlandish, but a growing body of work suggests it may be worth considering and further studying. If researchers can prove the theory and iron out the many argued-over details—both formidable tasks, as brain infections are difficult to study—Alzheimer’s could become a preventable illness.
