A<unk>  <unk> , commonly known as a mini-stroke, is a minor stroke whose noticeable symptoms usually end in less than an hour.<unk>  causes the same symptoms associated with strokes, such as weakness or numbness on one side of the body, sudden dimming or loss of vision, difficulty speaking or understanding language, slurred speech, or confusion. All forms of stroke, including<unk> , result from a disruption in blood flow to the central nervous system. A<unk>  is caused by a temporary disruption in blood flow to the brain, or cerebral blood flow (CBF). The primary difference between a major stroke and the<unk> 's minor stroke is how much tissue death (infarction) can be detected afterwards through medical imaging. While a<unk>  must by definition be associated with symptoms, strokes can also be symptomatic or silent. In silent stroke, also known as silent cerebral infarct (SCI), there is permanent infarction detectable on imaging, but there are no immediately observable symptoms. The same person can have major strokes, minor strokes, and silent strokes, in any order. The occurrence of a<unk>  is a risk factor for having a major stroke, and many people with<unk>  have a major stroke within 48 hours of the<unk> . All forms of stroke are associated with increased risk of death or disability. Recognition that a<unk>  has occurred is an opportunity to start treatment, including medications and lifestyle changes, to prevent future strokes.
