Transient Ischemic Attack (TIA)
A Transient Ischemic Attack (TIA) occurs when there is momentary loss of blood flow to an area of the brain. Because the blood flow is restored on its own, the symptoms of stroke go away on their own after minutes to hours.
A TIA is a sign that a stroke may occur and is therefore as dangerous as a stroke. We avoid the use of the term “mini-stroke” because it minimizes the importance of a TIA. There is a high risk of stroke in the days, weeks, and months after a TIA. It is important to seek medical attention as soon as signs of the TIA occur.
The signs of TIA and risk factors for TIA are the same as for stroke. A stroke can be prevented if risk factors are adequately assessed and managed after a TIA occurs.
