Lacunar stroke is when small blood vessels in the deep parts of our brain's hemispheres or brainstem, under the long-term influence of high blood pressure, diabetes, or other risk factors, cause the supplying arteries to undergo ischemic necrosis. The affected areas typically have a diameter of less than 1.5 to 2 centimeters, leading to an acute syndrome of neurological function impairment. Treatment of this disease first depends on the patient's age and risk factors to decide whether to use medication. Also, the prognosis is generally good; there is no need for moxibustion, as moxibustion has neither benefits nor harms for lacunar stroke.
