Ji X, Fu Y., et al. - Among older adults currently reporting insomnia, researchers evaluated how age of insomnia onset and gender impacts the well-established relationship between sleep parameters, cognition, and depression. Candidates with current insomnia complaints in China in 2018 were selected for inclusion. Age of insomnia onset (64 years old or before vs during/after 65), three factors from insomnia severity index (ISI; nighttime, daytime, and perception), excessive daytime sleepiness, and duration of sleep were among the included sleep measures. The average age of participants was 75 (SD = 7.1) years, and 62% were female. Correlations between daytime sleepiness, depressive symptoms, and poor cognitive performance were strong. Particularly among older women, late‐life onset insomnia was linked with poor cognitive performance. In males, only daytime sleepiness, with depression were found positively correlated with cognitive decline.
