\u3000\u3000The elderly population continues to rise in Taiwan, and its associated health issues are worthy of attention and discussion. In terms of sleep, older adults wake up in the middle of the night more often than younger adults, and take more time to fall asleep again. Sleep quality has been associated with memory consolidation. Previous studies have indicated that the deprivation of rapid eye movement (REM) sleep may lead to memory impairment. Since the total time of REM sleep decreases with age, it is reasonable to hypothesize that the sleep quality of elderly adults affects their memory performance.
\nMethods: One-hundred and sixty-two older adults were screened, and 32 cases of insomnia (accounting for 22.37% of the original smaple), and 40 normal controls were retained. The Mini-Mental State Examination (MMSE) was used as a preliminary assessment of cognitive functioning; and the Verbal Comprehension Index of the Wechsler Intelligence Scale was used to assess the participants\u2019 basic cognitive functioning. The Pittsburgh Sleep Quality Index Scale and the Insomnia Severity Scale were used to assess the quality of sleep. The Digit Span subtest of the Wechsler Adult Intelligence Scale, the Wechsler Memory Scale Logical Memory Test, and the Autobiographical Memory Test were used to assess memory. The same tests were administrated again 2 weeks later.
\nResults: There was a significant difference between the insomniac group and the normal group on the working memory indices after 2 weeks. In the insomniac group, memory loss was higher for autobiographical memories, and learning rates on logical memory was lower.
\nDiscussion: This study supports that quality of sleep affects memory consolidation in older adults. It may be that poor quality of sleep leads to the impairment of brain\u2019s capacity for deeper processing of information.<\/p>\n
