Memory Training in Insomnia With Cognitive Impairment

Participants will receive Cognitive Remediation Therapy (CRT) combined with Sleep Hygiene Education (SHE). CRT includes structured training sessions targeting attention, memory, visuospatial skills, calculation ability, logical reasoning, and language abilities. Sessions will be conducted daily for 50 minutes over 6 weeks. Sleep Hygiene Education will cover standard recommendations to improve sleep behaviors.

Participants will receive Sleep Hygiene Education (SHE) only, including guidance on adjusting sleep schedules, maintaining healthy sleep environments, minimizing stimulant intake, and managing sleep-related behaviors, without any CRT intervention.
