Self-Reported Sleep Disturbance Is Related to Increased Episodic Memory Errors, Perceived Concentration Difficulties

Studies examining the relationship between sleep difficulties and cognition have reported inconsistent findings. Our results show that sleep-disturbed participants had poorer episodic memory than nonsleep-disturbed participants. Though sleep-disturbed individuals also self-reported more concentration difficulties, significant differences were not found on other cognitive measures, such as attention or working memory.
