Bilateral subfrontal ischemic lesions are generally less severe, although the patient’s age, smoking or alcohol use, and chronic medical conditions should also be considered.
If the patient has not had cerebrovascular disease in the past and does not have the “three highs”, hyperhomocysteinemia, smoking or alcohol consumption, and only has small ischemic foci in the frontal lobes bilaterally on imaging, this is usually not serious. It is recommended that head MRI be reviewed in 6 months or 1 year; if there are no abnormal changes, treatment is usually not necessary.
If the patient has a past history of cerebrovascular disease with relatively large ischemic foci, or suffers from chronic diseases such as hypertension, diabetes mellitus, or abnormal lipid metabolism syndrome, the risk of further progression of the disease is higher and more serious. It is recommended to further improve the MRI examination of cerebrovascular, ultrasound of head and neck arteries, blood lipids and blood glucose, and timely control of risk factors.
In summary, it is recommended that patients who find bilateral subfrontal ischemic lesions should seek medical treatment in time to avoid delays.
