Cerebral ischemia

The transient insufficiency of the brain with symptoms is called transient ischemic attack, and it is a common acute cerebrovascular disease. Sudden onset of the patient, similar to the performance of cerebral hemorrhage or cerebral infarction, usually fully recovered to normal within 24 hours, often frightening family members, but can be recurrent. Patients with transient ischemic attack may develop cerebral infarction within 1 to 5 years. One-third to two-thirds of patients with cerebral infarction have had transient ischemic attacks.
