What is a common result of disrupted REM sleep?

Disrupted REM sleep is linked to various negative consequences for cognitive and emotional functioning. REM (Rapid Eye Movement) sleep plays a crucial role in several brain functions, particularly those associated with memory processing, learning, and emotional regulation. When REM sleep is interrupted, the brain struggles to effectively consolidate memories and manage emotions, leading to decreased overall mental function. This can manifest as difficulties with attention, memory retrieval, and decision-making, which are essential for daily functioning and overall cognitive performance.

The other outcomes listed—such as increased alertness, enhanced memory consolidation, and improved emotional stability—are generally associated with adequate and uninterrupted REM sleep, not its disruption. Therefore, the correct association of disrupted REM sleep is with decreased mental function, illustrating the importance of REM in maintaining cognitive health.
