Intermittent cerebral infarction, i.e. lacunar cerebral infarction, is an ischemic softening lesion of brain tissue caused by occlusion of tiny arteries in the deep part of the brain on the basis of hypertensive arterial infarction. Intermittent cerebral infarction belongs to a special type of cerebral infarction, with common symptoms such as tongue stiffness, slowed speech, etc. It is usually accompanied by dizziness and headache, numbness of limbs, vertigo and other symptoms. Cavernous cerebral infarction lesions usually range from 2-20 millimeters, with 2-4 millimeters being the most common. Because the lesions are small, most patients do not have obvious symptoms. The treatment is to follow the doctor’s instructions and take aspirin or statin drugs when the blood pressure, blood sugar and blood lipids are stable. Intermittent cerebral infarction is prone to recurrence, and prevention is the key. Patients with interstitial cerebral infarction should control their daily blood pressure, which can be detected on a daily basis and restored as soon as possible once it rises. If the symptoms are obvious or persistently cannot be relieved, they should consult a doctor in time for symptomatic treatment.
