The full name for TIA is Transient Ischemic Attack.
A TIA is a temporary blockage of blood flow to the brain. It is often referred to as a "mini-stroke" because it shares many of the same symptoms as a stroke, but the effects are temporary.
TIAs are a serious medical condition and should be treated promptly. If you or someone you know experiences symptoms of a TIA, it is important to seek immediate medical attention.
