A mini-stroke is a transient ischemic attack (TIA) that precedes the onset of a fatal and disabling stroke. It is caused by localized ischemia in the brain, which brings about neurological deficits. Although it is “transient”, “transient” is not “once and for all”. According to internationally accepted diagnostic criteria, the duration of neurological deficits due to mini-stroke should not exceed 24 hours! In fact, with symptoms lasting more than 1 to 2 hours, most patients can have a cerebral infarction as a consequence, and not only that, many patients have at least one cerebral infarction within 5 years, of which 1 in 10 will occur within 90 days of a mini-stroke if combined with early diagnosis or improper treatment. Many patients are often encountered in the clinic with dozens of mini-strokes a day, which seriously affect work and life.
