    Other common symptoms are a pulsing noise in the head, progressive weakness, numbness and vision changes as well as debilitating, excruciating pain. [4] [5] In serious cases, blood vessels rupture and cause bleeding within the brain (intracranial hemorrhage). [a] In more than half of patients with AVM, this is the first symptom. [7]

  4. Intracranial hemorrhage - Wikipedia

    Symptoms of SAH include a severe headache with a rapid onset (thunderclap headache), vomiting, confusion or a lowered level of consciousness, and sometimes seizures. [10] CT scan has 100% sensitivity of detecting SAH at 6 to 24 hours after symptoms onset. [3] The diagnosis is generally confirmed with a CT scan of the head.

  5. 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).

  6. Intraventricular hemorrhage - Wikipedia

    en.wikipedia.org/wiki/Intraventricular_hemorrhage

    Intraventricular hemorrhage (IVH), also known as intraventricular bleeding, is a bleeding into the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhagic stroke.

  7. Intracranial aneurysm - Wikipedia

    en.wikipedia.org/wiki/Intracranial_aneurysm

    Symptoms of an unruptured aneurysm are often minimal, but a ruptured aneurysm can cause severe headaches, nausea, vision impairment, and loss of consciousness, leading to a subarachnoid hemorrhage. Treatment options include surgical clipping and endovascular coiling, both aimed at preventing further bleeding.

  8. Brain ischemia - Wikipedia

    en.wikipedia.org/wiki/Brain_ischemia

    This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction/ischemic stroke. [2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage. [3] Ischemia leads to alterations in brain metabolism, reduction in metabolic rates, and energy crisis. [4]

  9. Stroke - Wikipedia

    en.wikipedia.org/wiki/Stroke

    If symptoms are maximal at onset, the cause is more likely to be a subarachnoid hemorrhage or an embolic stroke. Subtypes If the area of the brain affected includes one of the three prominent central nervous system pathways —the spinothalamic tract , corticospinal tract , and the dorsal column–medial lemniscus pathway , symptoms may include:
