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.
You can also have a “mini stroke,” called a transient ischemic attack, or TIA. This happens when there is a blockage, but it breaks up before causing any damage to the brain. Your brain health ...
A TIA may cause sudden dimming or loss of vision, aphasia, slurred speech, and mental confusion. The symptoms of a TIA typically resolve within 24 hours, unlike a stroke. Brain injury may still occur in a TIA lasting only a few minutes. Having a TIA is a risk factor for eventually having a stroke. [10] [11]
The leading hypotheses are some form of epileptic event, a problem with blood circulation around, to or from the brain, or some kind of migraine-like phenomenon. [ 8 ] [ 15 ] [ 16 ] [ 17 ] The differences are sufficiently meaningful that transient amnesia may be considered a heterogeneous clinical syndrome [ 2 ] with multiple etiologies ...
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]
Cigarette smoking: The procoagulant and atherogenic effects of smoking increase the risk for silent stroke. [21] [22] Smoking also has a deleterious effect on regional cerebral blood flow (rCBF). [23] [24] The chances of having a stroke increase with the amount of cigarettes smoked and the length of time an individual has smoked (pack years). [25]
The ischemic (ischaemic) cascade is a series of biochemical reactions that are initiated in the brain and other aerobic tissues after seconds to minutes of ischemia (inadequate blood supply). [1] This is typically secondary to stroke , injury, or cardiac arrest due to heart attack .
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [2]
