  3. Intracerebral hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Intracerebral_hemorrhage

    Intraparenchymal hemorrhage accounts for approximately 8-13% of all strokes and results from a wide spectrum of disorders. It is more likely to result in death or major disability than ischemic stroke or subarachnoid hemorrhage, and therefore constitutes an immediate medical emergency.

  4. Intracranial hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Intracranial_hemorrhage

    Trauma is the most common cause of intracranial hemorrhage. It can cause epidural hemorrhage, subdural hemorrhage, and subarachnoid hemorrhage. Other condition such as hemorrhagic parenchymal contusion and cerebral microhemorrhages can also be caused by trauma. [3]

  5. 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.

  6. Electrophysiological techniques for clinical diagnosis

    en.wikipedia.org/wiki/Electrophysiological...

    Electrocardiography is the measurement of these signals. EKGs are cheap, non-invasive and provide immediate results which has allowed for their proliferation of use in medicine. EKGs can be ordered as a one-time test, or can be continuously monitored in the case of patients wearing a holter monitor and/or admitted to a telemetry unit. EKGs ...

  7. Second-impact syndrome - Wikipedia

    en.wikipedia.org/wiki/Second-impact_syndrome

    Both direct blows to the head and blows to the body can produce subdural hematomas, diffuse cerebral edema, subarachnoid hemorrhage, and ischemic stroke, all pathologies that can lead to death. [40] By one estimate, the syndrome kills four to six people under the age of 18 per year. [33]

  8. Xanthochromia - Wikipedia

    en.wikipedia.org/wiki/Xanthochromia

    The most common cause for bleeding into the subarachnoid space is a subarachnoid hemorrhage from a ruptured cerebral aneurysm. [ 3 ] The most frequently employed initial test for subarachnoid hemorrhage is a computed tomography scan of the head, but it detects only 98% of cases in the first 12 hours after the onset of symptoms, and becomes less ...

  9. Pseudosubarachnoid hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Pseudosubarachnoid_hemorrhage

    A pseudosubarachnoid hemorrhage is an apparent increased attenuation on CT scans within the basal cisterns that mimics a true subarachnoid hemorrhage. [1] This occurs in cases of severe cerebral edema , such as by cerebral hypoxia .
