  2. Brain ischemia - Wikipedia

    en.wikipedia.org/wiki/Brain_ischemia

    Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.

  3. Cerebral infarction - Wikipedia

    en.wikipedia.org/wiki/Cerebral_infarction

    Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]

  4. Cerebrovascular disease - Wikipedia

    en.wikipedia.org/wiki/Cerebrovascular_disease

    Arteries supplying oxygen and nutrients to the brain are often damaged or deformed in these disorders. [2] The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2]

  5. Ischemia - Wikipedia

    en.wikipedia.org/wiki/Ischemia

    Acute ischemic stroke is a neurological emergency typically caused by a blood clot blocking blood flow in a vessel in the brain. [15] Chronic ischemia of the brain may result in a form of dementia called vascular dementia. [16] A sudden, brief episode (symptoms lasting only minutes) of ischemia affecting the brain is called a transient ischemic ...

  6. Lacunar stroke - Wikipedia

    en.wikipedia.org/wiki/Lacunar_stroke

    Moreover, focal narrowing of brain vessels and impairment of their ability to dilate in response to various stimuli may lead to a decreased cerebral blood flow and ultimately lacunar stroke. [11] Advanced age, chronic hypertension, smoking and diabetes mellitus are risk factors. It is unclear whether there is an association with alcohol ...

  7. Encephalomalacia - Wikipedia

    en.wikipedia.org/wiki/Encephalomalacia

    Ischemia: A decrease or restriction of circulating blood flow to a region of the brain which deprives neurons of the necessary substrates (primarily glucose); represents 80% of all strokes. A thrombus or embolus plugs an artery so there is a reduction or cessation of blood flow.

  8. Gliosis - Wikipedia

    en.wikipedia.org/wiki/Gliosis

    Micrograph showing gliosis in the cerebellum. Reactive astrocytes on the left display severe proliferation and domain overlap. Reactive astrogliosis is the most common form of gliosis and involves the proliferation of astrocytes, a type of glial cell responsible for maintaining extracellular ion and neurotransmitter concentrations, modulating synapse function, and forming the blood–brain ...

  9. Watershed stroke - Wikipedia

    en.wikipedia.org/wiki/Watershed_stroke

    Watershed stroke symptoms are due to the reduced blood flow to all parts of the body, specifically the brain, thus leading to brain damage. Initial symptoms, as promoted by the American Stroke Association, are FAST, representing F = Facial weakness (droop), A = Arm weakness (drift), S = Speech difficulty (slur), and T = Time to act (priority of intervention).
