TIA is a type of cerebrovascular disease, with the full name of transient ischemic attack. It is a temporary cerebral ischemia syndrome caused by blockage of cerebral blood vessels, mostly due to cerebral thrombosis. The onset time and frequency of TIA vary; if attacks occur frequently, a detailed brain CT scan should be performed at a hospital promptly, and medication such as blood-activating and stasis-resolving drugs should be taken according to medical advice.
The main causes of TIA include hemodynamic impairment, microembolism, cardiogenic embolism, vasospasm, and changes in blood composition. Symptoms are variable and may include hemiplegia, sensory deficits on one side of the body, aphasia, monocular visual disturbances, dizziness, nystagmus, and unsteady standing or walking. However, most symptoms and signs disappear within one hour and do not leave permanent damage.
Treatment of TIA mainly involves actively managing risk factors, using antiplatelet agents, medications to improve cerebral microcirculation, and vascular interventional therapy when necessary. At the same time, patients should also pay attention to lifestyle modifications, such as eating a light diet and avoiding high-calorie and high-fat foods, to prevent recurrence of TIA.
