Special protein in the brain's cleansing system may contribute to loss of brain function in Alzheimer's

AI Summary

Researchers have identified a specific brain protein whose age-related decline may contribute to the loss of brain function in Alzheimer's disease, which causes progressive nerve cell loss and memory impairment.

Alzheimer's disease is a progressive and permanent loss of nerve cells in the brain. The breakdown causes memory loss, functional impairment and personality changes. In a new study published in Nature Aging, researchers found that the age-related reduction in a specific protein may contribute to the loss of brain function in this disease.
