A TIA is a temporary disruption of blood flow to the brain, causing stroke-like symptoms that typically resolve within minutes to hours—often less than an hour. Unlike a full stroke, it doesn’t cause permanent brain damage, which is why people sometimes brush it off. However, health experts emphasize that a TIA is a serious warning sign. Studies indicate that up to 1 in 3 people who experience a TIA may have a full stroke within a year if underlying issues aren’t addressed, with many happening in the first few days.
The good news? Many risk factors are within your control. Age over 40 increases vulnerability because blood vessels naturally change over time, but lifestyle plays a huge role too.

Symptoms appear suddenly and mimic those of a stroke. Use the F.A.S.T. acronym from the American Stroke Association to remember them:
Face drooping — Does one side of your face feel numb or look uneven when you smile?
Arm weakness — Try raising both arms; does one drift downward or feel weak?
Speech difficulty — Is your speech slurred, or do you struggle to understand others?
Time to call emergency services — Even if symptoms disappear quickly, seek help right away.
