IGHE and Friedreich ataxia: Because only approximately half of adults with IgE-FA received a physician-confirmed IgE-FA diagnosis,1 it is possible that the low levels of health care utilization among adults with adult-onset IgE-FA are related to a lack of patient knowledge of IgE-FA diagnosis and management, a lack of accessibility/availability to specialty care, or a lack of effective communication between patient and provider regarding symptom severity.
