Clinical Information
  • A disorder resulting from inadequate blood flow in the vessels that supply the brain. Representative examples include cerebrovascular ischemia, cerebral embolism, and cerebral infarction.
  • A spectrum of pathological conditions of impaired blood flow in the brain. They can involve vessels (arteries; or veins) in the cerebrum, the cerebellum, and the brain stem. Major categories include intracranial arteriovenous malformations; brain ischemia; cerebral hemorrhage; and others.
  • Broad category of disorders of blood flow in the arteries and veins which supply the brain; includes cerebral infarction, brain ischemia, brain hypoxia, intracranial embolism and thrombosis, intracranial arteriovenous malformations, etc; not limited to conditions that affect the cerebrum, but refers to vascular disorders of the entire brain.
