As the world’s population ages, the number is increasing, expected to almost double every 20 years.While the causes of the disease are still not fully understood, scientists have been studying the build-up of tau proteins in the brain that lead to cognitive decline. The proteins clump and form tangles, disrupting signals along neurons, or brain cells.Now, a team from the University of Texas Medical Branch (UTMB) has found a potential way to get rid of the proteins.The team developed a...
