Implication

Randomized trial examines memory consolidation in individuals with insomnia and varying sleep durations, indicating specific impacts of subjective insomnia.

Key Points

This research investigates the effects of subjective insomnia and objective short sleep on memory consolidation during sleep.
Participants: 38 adults categorized into four groups based on insomnia and sleep duration
Assessments included procedural Motor Sequence Task (MST) and declarative Word Pairs Task (WPT)
Linear mixed-effects models analyzed the interaction of sleep condition, insomnia status, and sleep duration.
Participants without insomnia showed significant improvement in MST performance after sleep (Sleep–Wake=8.36% change; p=0.04)
Individuals with insomnia did not show memory improvement after sleep (-5.20% change; p=0.22)
All participants improved on the WPT after sleep, showing a significant main effect (Sleep–Wake=6.32% change, p=0.03).
