In the case of the right frontal lobe, small ischemic foci that appear alone do not require specific treatment. The cause of this small ischemic formation is mainly a blockage of the blood supplying arteries to the brain, distal terminal branches, or a disruption of blood supply, causing necrosis in the area of blood supply, or demyelinating changes. On imaging this manifests itself as small ischemic foci, which are particularly evident on MRI and often appear as high signal on FLAIR phase. In elderly patients over 60 years of age, they do not need to be treated and are a normal physiological phenomenon. In younger patients under 40 years of age, if they present, they need to look for an etiology, with or without hypertension, diabetes, hyperlipidemia, hyperhomocysteinemia, hyperfibrinogenemia, etc. If older patients have more lesions, it is also necessary to uncover relevant risk factors and provide symptomatic treatment to prevent the gradual increase of ischemic foci, which may also cause cognitive impairment.
