New Cause of Dementia Uncovered as Scientists Link 'Innocent' Peptide to Devastating Condition

Scientists may have discovered a new cause of Alzheimer's disease, which could hold the key to a new treatment. In a new commentary, a team at the University of California, Santa Cruz, argued that decades of dementia research have focused on the wrong protein. For years, and in hundreds of trials, scientists have focused on treatments targeting the protein amyloid beta — a hallmark of Alzheimer's that can form clumps in the brain that disrupt communication between nerve cells.
