Part 5/11:
In a significant step forward in understanding Alzheimer’s disease, a key mechanism involving brain cells known as microglia has been identified. These cells serve a protective role in maintaining brain health but can also exacerbate damage under stress. By blocking harmful microglia responses in studies, researchers noted a marked reduction in synapse damage and potentially harmful protein build-ups, setting the stage for future trials aimed at delaying or reversing the disease in humans.
