Abstract
Aim: The objective of this narrative review was to describe the versatile links between mental status and sleep in patients with Parkinson's disease. Methods: 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. Results: 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. Conclusion: We have demonstrated 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.

Enhancing Quality of Life in Indian Parkinson's Disease Patients with Improved Measurement of Psychological Domains: A Perspective. Ann Indian Acad Neurol 2021; 24:132-137. [PMID: 34220053 PMCID: PMC8232502 DOI: 10.4103/aian.aian_410_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2020] [Revised: 06/11/2020] [Accepted: 09/11/2020] [Indexed: 12/03/2022] Open
Abstract
Parkinson's disease (PD) is the second most common progressive neuro-degenerative disorder. Research in PD is gradually increasing in India due to increased clinical cases, which could double by 2030 worldwide. Although its prevalence is low in India as compared to other countries, the total burden is much higher due to the large population size. PD is progressively debilitating, with pronounced motor and nonmotor symptoms (NMSs) that severely affect the quality of life (QoL) of patients and their caregivers. The progressive nature of the disease lays great emphasis on doctors to focus on the patients' QoL. As a consequence, Health-related QoL (HRQoL) has gradually become one of the main indicators for assessing health-related outcome. There is a growing need to pay attention to the NMSs and a pressing need to look at the QoL of Indian patients with PD through a culture and value specific lens. Research into the holistic QoL assessment with emphasis on psychological domains may allow for the early evaluation and intervention of depressive and cognitive symptoms in PD. This could result into increased productivity, reduced morbidity, and healthcare cost, which would in turn result into better QoL of Indian PD patients.
