RESUMEN
The first COVID-19 contagion wave caused unprecedented restraining measures worldwide. In Italy, a period of generalized lockdown involving home confinement of the entire population was imposed for almost two months (9 March-3 May 2020). The present is the most extensive investigation aimed to unravel the demographic, psychological, chronobiological, and work-related predictors of sleep disturbances throughout the pandemic emergency. A total of 13,989 Italians completed a web-based survey during the confinement period (25 March-3 May). We collected demographic and lockdown-related work changes information, and we evaluated sleep quality, insomnia and depression symptoms, chronotype, perceived stress, and anxiety using validated questionnaires. The majority of the respondents reported a negative impact of confinement on their sleep and a delayed sleep phase. We highlighted an alarming prevalence of sleep disturbances during the lockdown. Main predictors of sleep disturbances identified by regression models were: female gender, advanced age, being a healthcare worker, living in southern Italy, confinement duration, and a higher level of depression, stress, and anxiety. The evening chronotype emerged as a vulnerability factor, while morning-type individuals showed a lower predisposition to sleep and psychological problems. Finally, working from home was associated with less severe sleep disturbances. Besides confirming the role of specific demographic and psychological factors in developing sleep disorders during the COVID-19 pandemic, we propose that circadian typologies could react differently to a particular period of reduced social jetlag. Moreover, our results suggest that working from home could play a protective role against the development of sleep disturbances during the current pandemic emergency.

Sleep disturbances are among the common nonmotor symptoms in patients with Parkinson's disease (PD). Sleep can be disrupted by nocturnal motor and nonmotor symptoms and other comorbid sleep disorders. Rapid eye movement sleep behavior disorder (RBD) causes sleep-related injury, has important clinical implications as a harbinger of PD and predicts a progressive clinical phenotype. Restless legs syndrome (RLS) and its related symptoms can impair sleep initiation. Excessive daytime sleepiness (EDS) is a refractory problem affecting patients' daytime activities. In particular, during the COVID-19 era, special attention should be paid to monitoring sleep problems, as infection-prevention procedures for COVID-19 can affect patients' motor symptoms, psychiatric symptoms and sleep. Therefore, screening for and managing sleep problems is important in clinical practice, and the maintenance of good sleep conditions may improve the quality of life of PD patients. This narrative review focused on the literature published in the past 10 years, providing a current update of various sleep disturbances in PD patients and their management, including RBD, RLS, EDS, sleep apnea and circadian abnormalities.

OBJECTIVES: Explore the evolution of sleep during the SARS-CoV-2 quarantine period and define associated factors. METHODS: An online survey of patients in quarantine. Questions targeted the conditions of quarantine, sleep related behaviours and exposure to factors known to affect sleep and circadian rhythms (light exposure and sport). RESULTS: In all, 1777 participants were included: 77% women and 72% aged 25-54 years. Quarantine conditions were most frequently in couples with children (36%) and in a house with a garden (51%). Forty-seven percent of participants reported a decrease in sleep quality during quarantine. Factors associated with a reduction in sleep quality by logistic regression were sleep reduction (OR 15.52 P<0.001), going to bed later (OR 1.72 P<0.001), getting up earlier (2.18 P=0.01), an increase in sleep-wake irregularity (OR 2.29 P<0.001), reduced exposure to daylight (OR 1.46 P=0.01) and increased screen use in the evenings (OR 1.33 P=0.04). CONCLUSION: Sleep quality tended to reduce during quarantine and this was associated with changes in sleep behaviours and light exposure, especially in the evening. In order to optimise sleep during quarantine, regular sleep and wake times, at least 1hour exposure to daylight and a reduction of screen use in the evenings are suggested.
