Friedreich ataxia (FRDA) is a multisystem neurodegenerative disorder and the most common hereditary ataxia. Dysphagia (swallowing impairment) is present in 98% of individuals with FRDA and is characterized by lingual and pharyngeal dysfunction (manifesting in impaired bolus preparation and transfer, and post-swallow residue in the mouth and pharynx), delayed swallow initiation, and entry of material into the airway (penetration/aspiration). Dysphagia severity correlates with disease severity and duration however no longitudinal studies describe changes in function in FRDA. The aim of this study was to investigate the progression of dysphagia in FRDA over one year. Fifty-nine individuals with..
