A 50-year-old woman was initially seen in 2016 for sleep disorders consultation, referred by Neurology because of progressive cerebellar ataxia syndrome with possible autonomic involvement and sleep-disordered breathing described as having stridorous sounds during her sleep. She had initially presented to Neurology because of issues with balance, and she had frequent falls at home. In 2016, her speech was clear, and she was able to ambulate steadily with a cane. ⋯ However, the study demonstrated rapid eye movement (REM) sleep without atonia in 62% of REM epochs (normal, up to 27%) and a soft inspiratory stridor during non-REM and REM sleep. The patient was lost to follow-up until she presented to us for reevaluation 3 years later. In the interim, she had been diagnosed with multiple system atrophy-cerebellar type (MSA-C) at another health-care institution.
