Abstract

Objectives: To investigate the relationship between sleep and cognitive function
among adolescent subjects in Riyadh.
Methods: The sample consisted of 98 (44% female) subjects aged 10–16 years. Each participant filled in a well-structured pre-coded questionnaire regarding demographic data, including a sleep questionnaire; cognitive function was assessed using the Cambridge Neuropsychological Automated Battery (CANTAB). The cognitive function outcome variables were response times in the attention-switching task (AST) and the percentage of correct answers in the pattern recognition memory (PRM) task.
Results: There were significant differences in measures of AST-latency (p = 0.005), AST-congruent (p = 0.012), and AST-incongruent (p = 0.009), while no significant difference was found in the PRM task score (p = 0.336) within gender groups. There was a significant correlation between sleep and AST switching cost (0.277, p = 0.006) and sleep and AST latency (0.188, p = 0.063) across the group.
Conclusion: This study showed that gender differences in cognitive function were significant in the group of adolescents. Additionally, this study shows that insufficient sleep can impair attention and accuracy in adolescents.
