Restriction of arterial blood supply to the brain associated with insufficient oxygenation to support the metabolic requirements of the tissue. [from HPO]

Pathological conditions involving arteries in the skull, such as arteries supplying the cerebrum, the cerebellum, the brain stem, and associated structures. They include atherosclerotic, congenital, traumatic, infectious, inflammatory, and other pathological processes. [from MONDO]

Acute onset neurological deficits such as weakness, dizziness, numbness, issues with speech, or visual changes related to sudden impairment of blood flow to a part of the brain due to occlusion or rupture of the middle cerebral artery to the brain. [from HPO]

Tissue necrosis in any area of the brain, including the cerebral hemispheres, the cerebellum, and the brain stem. Brain infarction is the result of a cascade of events initiated by inadequate blood flow through the brain that is followed by hypoxia and hypoglycemia in brain tissue. Damage may be temporary, permanent, selective or pan-necrosis. [from MONDO]

Pathological conditions of intracranial arteries supplying the cerebrum. These diseases often are due to abnormalities or pathological processes in the anterior cerebral artery; middle cerebral artery; and posterior cerebral artery. [from MONDO]
