Multiple small ischemic foci in the cerebral white matter and paraventricular areas of the bilateral frontoparietal lobes refers to multiple ischemia in the brain, which is found by cranial imaging tests mainly related to atherosclerosis. Cerebral ischemic foci, which is not a medical diagnosis, is not a disease name, and it is an imaging sign that is found through imaging tests such as cranial CT or MRI. The extreme majority are atherosclerosis, that is, secondary changes in the cerebral vasculature as a result of systemic atherosclerosis caused by chronic hypertension, hyperlipidemia, and diabetes mellitus. Acute stenosis of small vessels deep within the brain often leads to small cavernous infarcts, whereas chronic stenosis, with insufficient blood supply over time, results in ischemic foci. The cerebral ischemic foci are described as ischemic foci in whichever part of the brain they occur. When there are multiple small ischemic foci in the cerebral white matter of the frontal-parietal lobes and paraventricular areas bilaterally, patients may experience headache, dizziness, and memory loss. When cerebral ischemic foci appear, it is recommended that one should seek medical attention in a timely manner for early intervention and treatment under the guidance of a medical professional to avoid further progression of the ischemic foci.
