Small ischemic foci in the right frontal lobe, also known as small lacunar cerebral infarction foci, occur within the frontal lobe due to localized ischemic necrosis of brain tissue caused by capillary arteriosclerosis. Generally, the small ischemic foci do not form obvious clinical symptoms clinically, for example, the patient shows clumsiness in speech, as well as changes in mood and numbness of the limbs, which are not present. The presence of small ischemic foci in the right frontal lobe of the patient suggests that the small arteries in the brain have atherosclerosis. At this time, we must actively prevent and control the risk factors of cerebrovascular disease, including a low-salt and low-fat diet, and strictly control hypertension, diabetes, hyperlipidemia, and hyperhomocysteine. Patients should usually take oral BAY aspirin to antiplatelet aggregation or Bolivar to prevent the re-increase of ischemic foci in the brain and prevent the occurrence of cerebral infarction.
