Abstract: Cryptogenic stroke refers to the ischemic stroke with not yet clear etiology. With the development of medical technology, more and more rare causes of cryptogenic stroke have been found, such as paradoxical embolism, aortic atherosclerosis, cerebral artery dissection, hyperhomocysteinemia, obstructive sleep apnea-hypopnea syndrome, migraine, and single gene genetic disease etc. Based on relevant literature in recent years, this article reviews the progress of study on etiology of cryptogenic stroke, in order to increase awareness in clinical work and reduce the incidence of stroke.
