Findings

The results of the study show a strong correlation between sleep difficulties or issues and cognitive decline, especially Alzheimer’s disease (AD). With a thorough meta-analysis of 27 observational studies with over 69,000 participants, the researchers estimated the likelihood that those with sleep disorders would get cognitive impairment or AD in comparison to people who did not. The results of the meta-analysis showed that those with sleep issues were much more likely than people without sleep issues to develop AD, cognitive decline, and preclinical AD. It was discovered that those who had sleep issues were 1.55 times more likely to develop Alzheimer’s disease (AD), 1.65 times more likely to experience cognitive impairment, and 3.78 times more likely to develop preclinical AD. The importance of sleep disruptions as possible risk factors for AD and cognitive impairment is highlighted by these findings (Bubu et al., 2017).

Furthermore, the entire meta-analysis showed that those who struggled with sleep were 1.68 times more likely to experience cognitive impairment and/or AD together. Critical Analysis of a Research Scholarly Essay Paper The relationship between sleep issues and cognitive decline is supported by this body of research, underscoring the significance of treating sleep disruptions in the management and prevention of AD and associated illnesses. The study also calculated that sleep abnormalities may be responsible for 15% of AD cases in the general population, highlighting the significant public health benefit of treating sleep disturbances (Bubu et al., 2017). These results imply that, on a population level, treatments aimed at improving sleep quality and treating sleep disorders may be able to reduce the risk of cognitive decline and AD.

All things considered, the study’s conclusions offer strong proof of the link between sleep issues and cognitive decline, which has consequences for both public health initiatives and clinical practice. The population-attributable risk and risk estimates’ quantification emphasizes how critical it is to treat sleep disorders as a potentially modifiable risk factor for AD, opening up new directions for future study and preventative measures in this area.
