Minor stroke, also known as stroke aura, is called transient ischemic attack in modern medicine, which is a transient neurological deficit caused by local cerebral or retinal ischemia, with clinical symptoms generally lasting no more than 1 hour and no more than 24 hours at most, leaving no sequelae, but characterized by recurrent attacks. Transient ischemic attacks occur in middle-aged and elderly people, more men than women, and patients are often accompanied by cerebrovascular disease risk factors such as hypertension, atherosclerosis, diabetes mellitus or hyperlipidemia. The pathogenesis includes, on the one hand, narrowing of cerebral arteries due to atherosclerosis or arteritis and, on the other hand, transient ischemia in local cerebral areas due to fluctuations in blood pressure, resulting in transient hemiparesis and unfavorable speech. On the other hand, atherosclerotic plaque breaks down and blocks the blood supply artery of the brain, resulting in transient cerebral ischemic symptoms before the embolus dissolves. The symptoms of transient ischemic attack are complex and varied. If it occurs in the anterior cerebral circulation, symptoms such as hemiparesis, facial and tongue palsy, and sensory impairment may occur. If the lesion occurs in the posterior cerebral circulation, symptoms such as vertigo, tinnitus, balance disorder, diplopia or memory loss may occur. The treatment of transient ischemic attack mainly includes antiplatelet therapy, anticoagulation therapy and rehydration and volume expansion therapy. Meanwhile, such patients should undergo standardized preventive treatment for cerebrovascular disease. In conclusion, transient ischemic attack (mini-stroke) is a neurological deficit disease caused by localized cerebral ischemia, such as transient hemiparesis and unfavorable speech, and most of these patients are at high risk of cerebrovascular disease and should receive timely and standardized treatment.
