Advances in iconography of wake-up stroke

Abstract:

According to the latest survey report on disability and death of residents in our country，the incidence of stroke ranks first. Although the probability of death from stroke has decreased in recent years，the disability of the disease and the huge social expenditures caused by subsequent rehabilitation make the exploration and related research of the stroke still urgent. Acute ischemic stroke（AIS) accounts for 85% of all strokes，and wake-up（WUS） strokes account for about 20% of them. Because of the onset during sleep，the specific time of onset is unknown. In fact，many patients have the onset within a short period of time before waking up，and they have missed opportunities for thrombolysis or endovascular treatment，which ultimately leads to a poor prognosis. At present，there are more and more researches on the onset time of WUS，among which，imaging methods to predict the onset time of stroke after waking up to guide the treatment of WUS are particularly popular. This article is a review of recent advances in iconography of WUS.
