Daytime sleep disorders among patients with Parkinson’s disease in a tertiary medical centre in Kano, Northwestern Nigeria

Résumé fourni par la source

Parkinson’s Disease (PD) is commonly associated with sleep disorders, which may manifest years before disease diagnosis. Excessive Daytime Sleepiness (EDS) is a common problem seen in People with PD (PwPD) which is found to worsen by the presence of concomitant insomnia (sleep fragmentation, shortened sleep duration, early awakening) and anti-Parkinson’s medications. Identifying its presence and provision of appropriate intervention could significantly improve their Quality of Life (QoL). Using a cross-sectional study design, 100 PwPD and 100 healthy controls were enrolled over a period of 10 months to assess the prevalence of EDS using the Scales for Outcome in Parkinson’s Disease-Sleep (SCOPA-S) diagnostic tool. The SCOPA-S index questionnaire identified EDS in 64% of PwPD who have significant daytime sleepiness, including falling asleep unexpectedly either during the day or in the evening (U=1722.5, p<0.05), while sitting peacefully (U=279, p<0.05) or while talking to someone (U=2652, p<0.05) or had trouble staying awake during the day or in the evening (U=2769, p<0.05) in the past 1 month when compared to their controls. However, falling asleep while reading or watching television (U=3451.5, p=0.08) and whether patient perceives falling asleep during the day in the last one month as a problem (U=3473, p=0.064) did not differ between the 2 groups. The high prevalence of excessive daytime sleepiness among PwPD from the study should prompt all physicians on early detection aimed at improving their overall care and quality of life.
