  3. Intracranial aneurysm - Wikipedia

    en.wikipedia.org/wiki/Intracranial_aneurysm

    If an aneurysm ruptures, blood leaks into the space around the brain. This is called a subarachnoid hemorrhage. Onset is usually sudden without prodrome, classically presenting as a "thunderclap headache" worse than previous headaches. [11] [12] Symptoms of a subarachnoid hemorrhage differ depending on the site and size of the aneurysm. [12]

  4. Cerebrovascular disease - Wikipedia

    en.wikipedia.org/wiki/Cerebrovascular_disease

    The most common cause of a subarachnoid hemorrhage is an aneurysm rupture due to the weakened blood vessel walls and increased wall stress. [48] The neurologic symptoms are produced by the blood mass effect on neural structures, from the toxic effects of blood on the brain tissue, or by the increasing of intracranial pressure .

  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. Brain ischemia - Wikipedia

    en.wikipedia.org/wiki/Brain_ischemia

    The broad term, "stroke" can be divided into three categories: brain ischemia, subarachnoid hemorrhage and intracerebral hemorrhage. Brain ischemia can be further subdivided, by cause, into thrombotic, embolic, and hypoperfusion. [3] Thrombotic and embolic are generally focal or multifocal in nature while hypoperfusion affects the brain globally.

  7. Stroke - Wikipedia

    en.wikipedia.org/wiki/Stroke

    Some forms of stroke can cause additional symptoms. For example, in intracranial hemorrhage, the affected area may compress other structures. Most forms of stroke are not associated with a headache, apart from subarachnoid hemorrhage and cerebral venous thrombosis and occasionally intracerebral hemorrhage. [33]

  8. Intracerebral hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Intracerebral_hemorrhage

    Hemorrhagic stroke may occur on the background of alterations to the blood vessels in the brain, such as cerebral arteriolosclerosis, cerebral amyloid angiopathy, cerebral arteriovenous malformation, brain trauma, brain tumors and an intracranial aneurysm, which can cause intraparenchymal or subarachnoid hemorrhage. [1]

  9. Vasospasm - Wikipedia

    en.wikipedia.org/wiki/Vasospasm

    Vasospasm is the major cause of Prinzmetal's angina. Cerebral vasospasm may arise in the context of subarachnoid hemorrhage as symptomatic vasospasm (or delayed cerebral ischemia), where it is a major contributor to post-operative stroke and mortality. Vasospasm typically appears 4 to 10 days after subarachnoid hemorrhage, however the ...
