Multiple System Atrophy (MSA)

The intricate diagnosis and management of multiple system atrophy (MSA), an atypical parkinsonian disorder characterized by α-synuclein inclusions within oligodendroglia, is delineated through various cases in this chapter. MSA encompasses three phenotypes including striatonigral degeneration (SND), olivopontocerebellar atrophy (OPCA), and pure autonomic failure (PAF), either in isolation or combination, providing a spectrum that challenges diagnostic and therapeutic decisions. Various phenotypes, from pure parkinsonism to autonomic and cerebellar impairments, often intersect. Although MSA management predominantly revolves around symptomatic management with dopaminergic and non-dopaminergic strategies, the psychological and palliative aspects underpinning patient and caregiver support illustrate the holistic management of MSA. This chapter encapsulates these diagnostic intricacies, therapeutic approaches, and supportive care, embedding hope and pragmatic realism within the clinical path navigated in MSA.
