Quick Summary

DeMonica Amerson was diagnosed with multiple sclerosis in 2001 and managed the condition for nearly two decades. However, after experiencing severe symptoms in 2019, further testing revealed she never had MS but instead suffered from a rare autoimmune disorder. Dr. Robert Bermel of Cleveland Clinic notes that between 15% to 20% of patients diagnosed with MS are later found not to have the condition due to similar symptoms shared by other disorders.
