Sleep quality in elderly patients with mild cognitive impairment

Abstract

Objective To explore the sleep quality in elderly patients with mild cognitive impairment (MCI). Methods A total of 63 elderly patients with MCI were selected as the case group (MCI group), and 45 healthy elderly people were selected as the control group. Pittsburgh sleep quality index (PSQI) was measured, and the sleep quality of people between two groups were analyzed. Results The sleep quality in the case group was worse than that in the control group: subjective sleep quality [(2.81±0.83) vs (1.80±0.51)], sleep latency [(2.56±0.54) vs (1.42±0.47)], sleep disorder [(2.80±0.72) vs (1.87±0.71)], application of hypnotic drug[(2.73±0.60) vs (2.01±0.90)], sleep time [(1.96±0.63) vs (1.67±0.58)], sleep efficiency [(1.88±0.80) vs (1.50±0.63)] and the total score [(16.30±4.99) vs (11.76±4.63)] (P<0.05). Conclusions The elderly patients with MCI have bad sleep quality, which indicates that we should pay more attention to the nursing of those patients.
