Softening foci in the left frontal lobe do not require special treatment. The formation of softening foci in the frontal lobe is generally due to the formation of destructive lesions in the brain over a long period of time, which have become necrotic and liquefied and filled with cerebrospinal fluid, and is mainly a preventive measure against the original disease. If it is caused by cerebral infarction, patients need to take long-term oral medication for secondary prevention of cerebrovascular disease, such as long-term oral aspirin or Poliovel anti-platelet aggregation to prevent the reoccurrence of cerebral infarction. If patients have plaque in the neck vessels or high blood lipids, they should use drugs such as atorvastatin or resulvastatin for lipid-lowering, plaque stabilization, and endothelial protection. The diet should be low salt and low fat diet, avoid spicy and stimulating food, balanced nutrients, and strict control of hypertension, hyperglycemia and hyperhomocysteinemia in life.
