Transient ischemic attacks may recur. Transient ischemic attacks, also known as stroke precursors, are caused by the narrowing of blood vessels in the cerebral arteries, among other things, and result in the patient experiencing acute neurological deficits. Most patients recover completely within 1-2 hours of the onset of symptoms, with no signs or symptoms of neurologic deficit remaining, and there is no evidence of acute cerebral infarction on magnetic resonance brain imaging. In reality a transient ischemic attack is when a blood vessel is in a state where it is about to become occluded, but is not yet occluded. If the patient’s blood flow is restored during this period, the symptoms can disappear completely. If the patient’s blood vessel is completely occluded and there is no way for the blood flow to reopen, the patient will suffer a cerebral infarction. Transient ischemic attack must be treated in time for the cause of the disease, and patients should be given medication that activates blood circulation and improves blood stasis to reduce the probability of cerebral infarction.
