COVID-19 Can Cause Brain Cells To Fuse – Leading to Chronic “Long COVID” Neurological Symptoms — Researchers have discovere |
Scientists discovered that viruses like SARS-CoV-2 can cause brain cells to fuse, leading to chronic neurological symptoms. This process, where neurons either start firing together or stop working entirely, provides a new perspective on the long-term effects of viral infections on the brain and may apply to other viruses that infect the nervous system.
