Much like what can cause stroke, blood clots, plaque or artery spasms are also the causes of transient ischemic attack (TIA). Also called a mini stroke or warning stroke, TIA occurs when a blood clot or artery spasm suddenly blocks an artery. For a brief time, this blockage reduces or stops the blood from reaching the brain causing stroke-like symptoms. The body eliminates the blockage on it’s own.
The signs of the attack differ depending on what artery causes the transient ischemic attack. It’s important to seek medical attention after TIA to treat the underlying causes of transient ischemic attack and avoid stroke.
