Mini-strokes, i.e. transient ischemic attacks (TIAs), have the same clinical symptoms as strokes and are related to the arterial system involved. For example, the carotid artery system may manifest as hemiparesis; the vertebral basilar artery system may manifest as vertigo attacks. The blood supply system of the brain can be divided into the carotid artery system and the vertebral basilar artery system, and when different arterial systems are involved in transient ischemic attacks, they can show characteristic clinical symptoms. Involvement of carotid artery system mainly manifests as sudden onset of hemiplegia, hemiplegia, monocular transient blackout, transient speech disorder and so on. TIA with vertebral basilar artery system involvement mainly manifests as vertigo attacks, balance disorders, binocular vision disorders, diplopia, dysphagia, etc., and seldom results in impaired consciousness. Since TIA is caused by a transient interruption of the blood supply to the brain, the clinical manifestations that occur can disappear on their own within minutes to hours. In the event of a mini-stroke, it is recommended that the people concerned should not be careless, and need to consult a doctor in a timely manner and standardize their treatment under the guidance of a professional physician.
