  2. Transient ischemic attack - Wikipedia

    en.wikipedia.org/wiki/Transient_ischemic_attack

    A transient ischemic attack (TIA), commonly known as a mini-stroke, is a temporary (transient) stroke with noticeable symptoms that end within 24 hours. A TIA causes the same symptoms associated with a stroke, such as weakness or numbness on one side of the body, sudden dimming or loss of vision, difficulty speaking or understanding language or slurred speech.

  3. Vertebrobasilar insufficiency - Wikipedia

    en.wikipedia.org/wiki/Vertebrobasilar_insufficiency

    Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain.The posterior circulation supplies the medulla, pons, midbrain, cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex. [1]

  4. Ocular ischemic syndrome - Wikipedia

    en.wikipedia.org/wiki/Ocular_ischemic_syndrome

    Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...

  5. Amaurosis fugax - Wikipedia

    en.wikipedia.org/wiki/Amaurosis_fugax

    Atherosclerotic carotid artery: Amaurosis fugax may present as a type of transient ischemic attack (TIA), during which an embolus unilaterally obstructs the lumen of the retinal artery or ophthalmic artery, causing a decrease in blood flow to the ipsilateral retina. The most common source of these athero-emboli is an atherosclerotic carotid artery.

  6. Cerebrovascular disease - Wikipedia

    en.wikipedia.org/wiki/Cerebrovascular_disease

    Transient ischemic attack (TIA) also called a mini-stroke. This is a condition in which the blood flow to a region of the brain is blocked, but blood flow is quickly restored and the brain tissue can fully recover. The symptoms are only transient, leaving no sequelae, or long-term deficits. [46]

  7. Transient global amnesia - Wikipedia

    en.wikipedia.org/wiki/Transient_global_amnesia

    Although confusion is sometimes reported, others consider this an imprecise observation, [7] but an elevated emotional state (compared to patients experiencing transient ischemic attack, or TIA) is common. [8] In a large survey, 11% of individuals in a TGA state were described as exhibiting "emotionalism" and 14% "fear of dying". [9]

  8. Silent stroke - Wikipedia

    en.wikipedia.org/wiki/Silent_stroke

    A silent stroke differs from a transient ischemic attack (TIA). In TIA, symptoms of stroke are exhibited which may last from a few minutes to 24 hours before resolving. A TIA is a risk factor for having a major stroke and subsequent silent strokes in the future. [8]

  9. Carotid artery stenosis - Wikipedia

    en.wikipedia.org/wiki/Carotid_artery_stenosis

    The surgical mortality of endarterectomy ranges from 1–2% to as much as 10%. Two large randomized clinical trials have demonstrated that carotid surgery done with a 30-day stroke and death risk of 3% or less will benefit asymptomatic people with ≥60% stenosis who are expected to live at least 5 years after surgery.
