OBJECTIVES:

We sought to document the prevalence and nature of sleep-disordered breathing (SDB) in individuals with Friedreich ataxia (FRDA) as well as establish the relationship, if any, between SDB and clinical parameters of FRDA.

METHODS:

Eighty-two individuals with FRDA were administered the Epworth Sleepiness Scale on an annual basis for up to 3 years. Individuals were referred for a sleep study if they had an Epworth Sleepiness Scale score >8 or had clinical symptoms suggestive of SDB.
