How much blockage in cerebral blood vessels causes symptoms?
There is no clear clinical threshold indicating how much blockage of cerebral blood vessels will cause symptoms. Generally, symptoms appear once cerebral vessel occlusion occurs, though their severity may vary. The details are as follows:
Cerebral vascular occlusion usually refers to the blockage of blood vessels in the brain by thrombi, detached plaques, tumor emboli, parasites, or similar substances, leading to ischemia and functional impairment in the affected brain tissue. If the blockage is mild, it may manifest as insufficient cerebral blood supply, and patients might experience symptoms such as headache, nausea, and vomiting. However, more severe blockages can lead to neurological deficits, including hemiplegia, aphasia, and slurred speech. If cerebral vessel occlusion is detected, patients may be treated under medical supervision with medications such as enteric-coated aspirin tablets or warfarin sodium tablets.
Once symptoms of cerebral vessel occlusion are noticed, it is recommended to seek prompt medical attention at a professional hospital for timely treatment. Self-medication should be avoided to prevent serious complications. In daily life, individuals should actively manage body weight and engage in aerobic exercises such as walking or cycling.
