Prevalence of sleep disorders in Parkinson’s disease patients in two neurology referral hospitals in Ethiopia
Peer Reviewed
Abstract
The article "Prevalence of sleep disorders in Parkinson’s disease patients in two neurology referral hospitals in Ethiopia" investigates the prevalence of sleep disorders among Parkinson's disease (PD) patients in Ethiopia. The study found that all 155 surveyed patients reported some form of sleep problem, with over 43.9% scoring above 18 on the Parkinson's Disease Sleep Scale (PDSS-2), indicating severe sleep disturbances. Additionally, 49.7% had possible or definite excessive daytime somnolence, as indicated by an Epworth Sleepiness Scale (ESS) score of 9 or higher. These findings highlight the high prevalence of sleep disorders in Ethiopian PD patients, suggesting a need for further investigation into contributing factors such as poverty and race.
Key Questions about Sleep Disorders in Parkinson's Disease Patients in Ethiopia
What is the prevalence of sleep disorders among Parkinson's disease patients in Ethiopia?
The study found that all 155 surveyed PD patients reported some form of sleep problem. Over 43.9% had a PDSS-2 score above 18, indicating severe sleep disturbances. Additionally, 49.7% had possible or definite excessive daytime somnolence, as indicated by an ESS score of 9 or higher.
What tools were used to assess sleep disorders in the study?
The researchers utilized the Parkinson's Disease Sleep Scale version 2 (PDSS-2) and the Epworth Sleepiness Scale (ESS) to evaluate sleep symptoms among the participants.
What factors are associated with severe sleep disorders in Ethiopian PD patients?
The study found a significant association between a high ESS score and a Hoehn & Yahr score greater than 4, suggesting that more advanced stages of PD are linked to increased daytime sleepiness.
How do the prevalence rates of sleep disorders in Ethiopian PD patients compare to those in other regions?
The prevalence of severe sleep disorders in Ethiopian PD patients is among the highest reported globally, indicating a potentially unique pattern or contributing factors in this population.
By addressing these questions, the article underscores the high prevalence of sleep disorders among PD patients in Ethiopia and emphasizes the need for further research to understand the underlying causes and to develop effective management strategies.
