A strategic approach of the management of sleep-disordered breathing in multiple system atrophy

Multiple system atrophy (MSA) is a rare neurodegenerative disorder characterized by autonomic dysfunction associated with a combination of cerebellar, parkinsonian, or pyramidal signs. Sleep-disordered breathing (SDB) such as stridor, obstructive sleep apnea (OSA) and central sleep apnea (CSA) are common in MSA and can impact survival. Several studies have evaluated treatment modalities. However, the optimal strategy often remains unclear in these patients. This review aims to provide an overview of the current evidence on treatment of SDB in MSA.
