Impaired Brain Waste Clearance Linked to Alzheimer’s Disease

The study revealed that the neurons responsible for waste clearance are the first to die in Alzheimer's, offering new insights into disease progression and potential treatments. According to the researchers, “It showed these neurons previously known for cognitive function, also control the blood and fluid movement that drives the cleaning system. Weakening these neurons leads to impaired waste clearance.” The researchers also found that commonly prescribed Alzheimer’s drugs partially restored the waste fluid flow.
