  2. Hunt and Hess scale - Wikipedia

    en.wikipedia.org/wiki/Hunt_and_Hess_scale

    The Hunt and Hess scale, introduced in 1968, is one of the grading systems used to classify the severity of a subarachnoid hemorrhage based on the patient's clinical condition. It is used as a predictor of patient's prognosis/outcome, with a higher grade correlating to lower survival rate.

  4. Intracerebral hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Intracerebral_hemorrhage

    Intracerebral hemorrhage (ICH), also known as hemorrhagic stroke, is a sudden bleeding into the tissues of the brain (i.e. the parenchyma), into its ventricles, or into both. [ 3 ] [ 4 ] [ 1 ] An ICH is a type of bleeding within the skull and one kind of stroke (ischemic stroke being the other).

  5. 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]

  6. Stroke - Wikipedia

    en.wikipedia.org/wiki/Stroke

    A third of intracerebral bleed is into the brain's ventricles. ICH has a mortality rate of 44 percent after 30 days, higher than ischemic stroke or subarachnoid hemorrhage (which technically may also be classified as a type of stroke [2]).

  7. Traumatic brain injury - Wikipedia

    en.wikipedia.org/wiki/Traumatic_brain_injury

    Subarachnoid hemorrhage approximately doubles mortality. [142] Subdural hematoma is associated with worse outcome and increased mortality, while people with epidural hematoma are expected to have a good outcome if they receive surgery quickly. [76] Diffuse axonal injury may be associated with coma when severe, and poor outcome. [10]

  8. Cerebral arteriovenous malformation - Wikipedia

    en.wikipedia.org/wiki/Cerebral_arteriovenous...

    Cerebral hemorrhage appears to be most common. [3] One long-term study (mean follow up greater than 20 years) of over 150 symptomatic AVMs (either presenting with bleeding or seizures) found the risk of cerebral hemorrhage to be approximately 4% per year, slightly higher than the 2–4% seen in other studies.

  9. 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]
