Odnosi između poremećaja spavanja i neuropsihijatrijskih simptoma kod Parkinsonove bolesti: narativni pregled

Sažetak

The objective of this narrative review is to describe versatile links between mental status and sleep in patients with Parkinson's disease. That is why we searched randomized controlled studies, observational studies, meta-analyses, systematic reviews, and case reports written in English in PubMed during 2015-2021. Additionally, to ensure the completeness of the review, a second, more in-depth literature search was performed using the same electronic database with the search inquiries of increased specificity.  The information on pathophysiology, epidemiology, clinical features and risk factors was extracted and formed the basis for this review. Despite how widespread sleep disorders in Parkinson’s disease are, there is no systematic information about their association with neuropsychiatric symptoms, such as depression, anxiety, impulse control disorders, apathy, cognitive impairment and psychosis. In this review we described relationships between these non-motor symptoms of Parkinson’s disease, their timeline occurrence, gap in knowledge and perspectives for further research. We suppose that early treatment of sleep disorders in patients with Parkinson’s disease can reduce the incidence and extent of neuropsychiatric symptoms. They demonstrate multiple, multidirectional relationships between sleep disorders and neuropsychiatric symptoms. However, some of them remain unexplored. The described knowledge can be applied to further study the possibility of influencing neuropsychiatric symptoms through the correction of sleep disorders in patients with different stages of Parkinson’s disease.
