A history of transient cerebral ischemic attack can occur in part before the cerebral infarction attack, and if the patient has transient cerebral ischemic attack, timely treatment should be given to prevent the formation of cerebral infarction death. Transient cerebral hypoperfusion mainly manifests as transient limb weakness or transient confusion. It is recommended to consult the neurology department, improve head CT and MRI examination, and give single-combination anti-platelet aggregation drugs or double-combination anti-platelet aggregation drugs according to the ABCD2 score. If the patient has atrial fibrillation, warfarin or a new oral anticoagulant drug may be given. Transient ischemic attack is a transient, or transient focal, brain or retinal dysfunction caused by an intracranial arterial lesion. Clinical symptoms usually last 10-15 minutes, most recover within 1 hour and do not exceed 24 hours, and no signs and symptoms of neurological deficits are usually left behind. Imaging examinations, such as cranial CT or MRI, generally have no responsible lesion, and their clinical signs and symptoms can be varied, depending on the vessels involved in the lesion. If the lesion is of the internal carotid artery system, the patient may present with episodes of limb movement and sensory abnormalities, as well as hemianopia and speech dysfunction. If the patient has a vertebrobasilar system lesion, he or she may experience episodes of dizziness, nausea, and vomiting, as well as ataxia and balance disorders.
