Mild cerebral infarction can usually be fully recovered within 2-4 weeks, and for those who fail to recover in time, the golden recovery period is within 3 months. Mild cerebral infarction usually has mild symptoms, most of them have no obvious headache, no impairment of consciousness, and often manifest as simple motor light hemiparesis, dysarthria-hand clumsiness syndrome, pure sensory stroke, and ataxic light hemiparesis. Mild cerebral infarction is usually a small penetrating artery in the cerebral hemisphere or deep brainstem with lesions in the vessel wall based on chronic hypertension, resulting in lumen occlusion and the formation of small cystic lesions. Minor cerebral infarction is mostly lacunar cerebral infarction, which often recurs. If combined with risk factors such as hypertension and diabetes, the risk factors need to be controlled in time. During the recovery period, bad habits should be improved, smoking and alcohol should be quitted, weight should be controlled, exercise should be strengthened appropriately, and medication should be taken on time as prescribed by the doctor to reduce recurrence.
