What is a Transient Ischemic Attack (TIA)?
Transient ischemic attacks (TIAs) are often early warning signs of a more serious and debilitating stroke. About one-third of all strokes are preceded by one or more “mini-strokes,” known as (TIAs). TIAs can occur days, weeks or months before a stroke. The symptoms typically come on quickly and last a relatively short time, anywhere from a few minutes to several hours, and there is complete recovery within 24 hours. TIAs are caused by temporary interruptions in the blood supply to the brain. An example of a TIA might be if you experience weakness in an arm or leg or have a loss of vision that disappears with complete resolution within a short time. Since TIAs are temporary it is easy to ignore them believing the problem has resolved. However, it is dangerous to ignore TIAs, because the underlying problem that caused the TIA continues to exist.
