About this trial

This observational cross-sectional study aims to examine the association between sleep quality and cognitive functions in healthy young adults. Subjective sleep quality will be assessed using the Pittsburgh Sleep Quality Index, and objective sleep parameters will be collected using a wearable device over five consecutive days. Cognitive functions will be evaluated at a single assessment session using standardized neuropsychological tests, including measures of attention, executive functions, and verbal memory. The study seeks to explore relationships between subjective and objective sleep measures and cognitive performance. Findings from this study may contribute to a better understanding of how sleep quality is associated with cognitive functioning in healthy young adults.
