  2. Cerebral hypoxia - Wikipedia

    en.wikipedia.org/wiki/Cerebral_hypoxia

    Silent stroke is a stroke which does not have any outward symptoms, and the patient is typically unaware they have had a stroke. Despite its lack of identifiable symptoms, a silent stroke still causes brain damage and places the patient at increased risk for a major stroke in the future.

  3. Brain ischemia - Wikipedia

    en.wikipedia.org/wiki/Brain_ischemia

    Extremely low blood pressure can also result from drug overdose and reactions to drugs. Therefore, brain ischemia can result from events other than heart attacks. [citation needed] Congenital heart defects may also cause brain ischemia due to the lack of appropriate artery formation and connection. People with congenital heart defects may also ...

  4. Hypoxia (medicine) - Wikipedia

    en.wikipedia.org/wiki/Hypoxia_(medicine)

    Hypoxia can be due to external causes, when the breathing gas is hypoxic, or internal causes, such as reduced effectiveness of gas transfer in the lungs, reduced capacity of the blood to carry oxygen, compromised general or local perfusion, or inability of the affected tissues to extract oxygen from, or metabolically process, an adequate supply ...

  5. Histotoxic hypoxia - Wikipedia

    en.wikipedia.org/wiki/Histotoxic_hypoxia

    During a stroke, there is an interruption in the blood supply followed by reperfusion which leads to histotoxic hypoxia because of an accumulation of reactive oxygen species (ROS). [4] In the case of inflammatory diseases, histotoxic hypoxia can also be triggered by ROS from mitochondrial damage in the active lesions of chronic multiple sclerosis.

  6. Cerebral infarction - Wikipedia

    en.wikipedia.org/wiki/Cerebral_infarction

    A head and neck CT angiogram can be performed within 6 hours of onset of symptoms to see where the occlusion may be located which can help in determining the cause of the stroke. [29] In people who die from a stroke an autopsy can reveal additional diseases or conditions beyond the stroke itself, as well as uncover uncommon causes of a stroke. [30]

  8. Cytopenia - Wikipedia

    en.wikipedia.org/wiki/Cytopenia

    There are also two general causes of cytopenia: autoimmune and refractory. Autoimmune cytopenia is caused by an autoimmune disease when your body produces antibodies to destroy the healthy blood cells. Refractory cytopenia is caused by bone marrow not producing healthy blood cells, and can be a result of cancer.

  9. Cerebrovascular disease - Wikipedia

    en.wikipedia.org/wiki/Cerebrovascular_disease

    The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and sometimes a hemorrhagic stroke. [2] Hypertension (high blood pressure) is the most important contributing risk factor for stroke and cerebrovascular diseases as it can change the structure of blood vessels and result in atherosclerosis .
