What is the main cause of a TIA?
The blockage in the blood vessels responsible for most TIAs is usually caused by a blood clot that’s formed elsewhere in your body and travelled to the blood vessels supplying the brain. It can also be caused by pieces of fatty material or air bubbles.
Are TIA precursor to stroke?
A transient ischemic attack has the same origins as that of an ischemic stroke, the most common type of stroke. In an ischemic stroke, a clot blocks the blood supply to part of your brain. In a transient ischemic attack, unlike a stroke, the blockage is brief, and there is no permanent damage.
Are TIAs serious?
TIAs look like strokes in terms of signs and symptoms, but they are temporary. In other words, they leave no lasting brain damage or residual symptoms. However, they serve as a warning sign that a person is at higher risk of a major stroke and should seek immediate medical attention.

What causes a TIA in a stroke patient?
TIAs are caused by a clot or blockage in the brain. The blockage is short term. The clot usually dissolves on its own or gets dislodged, and symptoms usually last for a short time. A TIA happens before about 12 % of all strokes.
