An overview of the current management and emerging therapies of Multiple system atrophy

INTRODUCTION: Multiple system atrophy is a sporadic α-synucleinopathy, characterized by parkinsonism, cerebellar and pyramidal signs combined in different ways, in association with autonomic failure. In absence of disease-modifying therapies, management is directed toward symptomatic treatment and maintenance of function. AREAS COVERED: This review critically appraises current evidence, highlights novel therapeutic strategies, and provides guidance for clinical practice and future research directions. A literature search without date restrictions was conducted using PubMed to identify published studies relevant to this review. Motor symptom interventions are primarily levodopa-based, yielding partial and transient responses, especially in MSA-P, whereas dopaminergic agonists, MAO-B inhibitors, amantadine, and device-aided therapies provide a limited or short-lived benefit. Physiotherapy, occupational therapy, and multidisciplinary rehabilitation are integral to motor symptoms management. Non-motor symptoms management target autonomic failure (neurogenic orthostatic hypotension, urinary/sexual dysfunction, etc.), gastrointestinal dysmotility and sleep disorders (REM sleep Behavior Disorder, stridor, etc.), using a stepwise combination of lifestyle measures, pharmacological agents and device-aided interventions. EXPERT OPINION: Management of MSA remains largely symptomatic. Multimodal treatment and integration of rehabilitative and non-pharmacological strategies are critical, while ongoing trials in neuroprotection and neuromodulation represent key avenues to improve long-term outcomes.
