New study aims to sharpen diagnosis of rare brain disease

This study looks at two different lab tests (live-cell and fixed-cell) to see which one is better at diagnosing MOGAD, a rare autoimmune disease that affects the brain and nerves. Researchers will test 240 adults who are suspected of having MOGAD, along with people who have other similar conditions, to measure how accurate each test is. The goal is to find the best way to diagnose MOGAD in China and improve patient care.
