What Causes a Transient Ischemic Attack?

Last updated 3 years ago

Transient ischemic attacks, or TIAs, are also sometimes referred to as mini strokes. That is because they mimic full-blown strokes but only last for a brief period of time. However, while TIAs tend to be short and rarely cause any damage, they should be taken seriously as indicators that a larger stroke could be imminent.

TIAs are caused by blood clots that block the flow of blood to the brain temporarily. During a stroke, these blockages stay in place until treatment is provided, but with TIAs, they clear up on their own – often in minutes. A number of conditions can trigger these blood clots, but they are most commonly associated with heart disease, atherosclerosis, and abnormal clotting.

Stroke is a medical emergency. If you or someone you know is experiencing stroke symptoms, get help immediately at the ER at Oak Hill Hospital and our Certified Primary Stroke Center. Get answers to your questions about stroke care, our ER, and the other services at our Brookesville hospital by calling (888) 741-5120.
