After 2 and 4 weeks, the acupuncture group's PSQI and ISI scores were significantly lower than the sham group (P<0.05) and closer to the healthy group
The acupuncture group showed significant increases in MoCA scores after 2 and 4 weeks (P<0.05)
Statistical differences in sleep spindle density and duration were observed between the acupuncture and sham groups (P<0.001).
