Left parietal lacunar ischemic foci are usually not completely cured, and plaque stabilization through antiplatelet and lipid-lowering therapy can reduce the risk of recurrence. Left parietal lobe lacunar ischemic foci are considered to be the presence of small arterial infarction, resulting in a small number of brain cells necrosis, brain cells of patients with cerebral infarction can not be completely restored to normal. Patients with lacunar cerebral infarction should strictly control their diet and take oral aspirin and atorvastatin to slow down the progress of atherosclerosis and prevent recurrent attacks of lacunar cerebral infarction. Patients with cerebral atherosclerosis should be actively treated to avoid the occurrence of cerebral infarction. Once cerebral infarction occurs, brain cells will be necrotic in a short period of time, and it cannot be completely restored to normal even after active treatment, and the key to treatment is prevention. Patients with lacunar cerebral infarction should go to regular hospitals in time to avoid active treatment under the guidance of physicians to avoid recurrent attacks.
