Correlation between Poststroke Insomnia and Circadian Rhythm Disturbance Research Progress

Poststroke insomnia is one of the common problems faced by patients after stroke. Related studies show that about 30% -50% of stroke patients have insomnia symptoms after the onset of stroke. These patients often show symptoms such as difficulty in falling asleep, shallow sleep and easy to wake up, and early wake up, which not only affect the rehabilitation process of patients, but also may aggravate their condition, leading to mood fluctuations and cognitive function decline, forming a vicious circle. The pathogenic factors of insomnia after stroke are varied, including physiological factors, psychological factors, and environmental factors. Among them, the circadian rhythm disorder is one of the important causes of post-stroke insomnia. In recent years, with the deepening of medical research, the understanding of post-stroke insomnia caused by circadian rhythm disturbances is also increasing. This paper aims to explore the progress of the correlation between circadian rhythm disturbance and insomnia after stroke, in order to provide new ideas and methods for the rehabilitation and treatment of insomnia patients after stroke.
