Current advances in the clinical management of Perry syndrome: is there hope for the future?

INTRODUCTION

Perry syndrome (PS) is a rare, inherited neurodegenerative disorder caused by mutations in the DCTN1 gene. It is characterized by parkinsonism, neuropsychiatric symptoms, central hypoventilation, and progressive weight loss, typically leading to a rapid disease course and early death. As genetic testing becomes more widespread, PS is increasingly diagnosed, and its clinical spectrum is expanding.

AREAS COVERED: The authors conducted a comprehensive search of public databases through September 2025 to identify original research, conference proceedings, and book chapters related to Perry syndrome. This review summarizes the current understanding of the disease, including its clinical, pathologic, and genetic aspects. The authors also provide practical recommendations for managing symptoms, particularly through optimization of dopaminergic therapy, antidepressive treatment, and noninvasive or invasive ventilation support, which can greatly improve quality of life and extend survival.

EXPERT OPINION: Although there are currently no approved disease-modifying therapies for PS, recent research into the underlying pathology, such as TDP-43 and axonal transport dysfunction, offers promising targets for future treatments. A new staging system for PS is recommended for PS, which will help to standardize the clinical assessment of PS and guide therapeutic decision-making.
