Liu J, Walton J, DeVries A, Nelson R. Disruptions of Circadian Rhythms and Thrombolytic Therapy During Ischemic Stroke Intervention Frontiers in Neuroscience. 2021 Jan;15. Abstract Several endogenous and exogenous factors interact to influence stroke occurrence, in turn contributing to discernable daily distribution patterns in the frequency and severity of cerebrovascular events. Specifically, strokes that occur...

BACKGROUND INFORMATION Modern electric lighting enables people to work, sleep, eat, and receive services throughout the 24-hour day. As a result, many individuals encounter new patterns and types of electrical light, change the timing of their meals, and experience sleep disturbances and other stresses. Those factors can disrupt circadian rhythms and possibly lead to adverse...
