Transient Ischemic Attacks (TIAs): A Warning Sign for Stroke

Imagine this: you’re going about your day when, out of nowhere, your arm feels weak, or your speech gets jumbled. Just as quickly as it started, it stops. You shrug it off, thinking, “That was odd,” and go on with your routine. Days later (why is it always the weekend or the holidays), you casually mention it to your primary care doctor over the phone, who immediately sounds concerned and urges you to go to the hospital.

That brief episode was a serious warning sign from your body that something is wrong. It might have been a Transient Ischemic Attack (TIA), or "mini-stroke." While it doesn’t cause lasting damage, it is a red flag that a major stroke could be just around the corner.

What Is a Transient Ischemic Attack (TIA)?

A TIA occurs when blood flow to a part of your brain is temporarily interrupted, cutting off the oxygen and nutrients your brain needs. Unlike a full stroke, the blockage resolves quickly, and the symptoms usually disappear within minutes or hours. That’s why it’s called "transient."

However, just because it’s transient doesn’t mean it’s harmless. A TIA is your brain’s way of warning you, “Something’s wrong, don’t ignore this! There’s a problem with your blood flow.”  

 

What Are the Symptoms of a TIA?

The challenge with TIAs is that the symptoms appear and disappear quickly, making them easy to overlook. Here are some signs to watch for:

  • Symptoms are sudden. Remember the mnemonic SUDDEN ACT:

    • Speech Difficulty: Trouble speaking or understanding speech.

    • Unexplained imbalance: Sudden loss of balance/coordination, leaning to one side.

    • Double Vision: Experiencing double or blurred vision.

    • Drooping face: One side of the face may droop.

    • Eye Problems: Sudden trouble seeing in one or both eyes.

    • Numbness: Sudden numbness in the face, arm, or leg.

    • Arm Weakness: Weakness or difficulty moving one or both arms.

    • Confusion: Sudden confusion, trouble speaking or understanding speech.

    • Time to call 911.

  • For those that would like a shorter one, remember the mnemonic FAST:

    • Face drooping

    • Arm weakness

    • Speech difficulty

    • Time to call 911.

 

Wait, what? TIA has the exact same symptoms as a stroke! That’s the tricky part, since TIAs are "transient," many people don’t take them seriously. Think of it like your body’s "check engine light." When it comes on, don’t ignore it, get it checked before things get serious!

 

Why Are TIAs So Important?

We’ve established that a TIA is your body’s way of warning you that something isn’t right with your brain. It’s not just a random occurrence, it’s a critical alert. In fact, about 12% of major strokes are preceded by a TIA, often occurring just days or weeks before. That’s why recognizing and responding to a TIA is so important,

The good news is that a TIA gives you the opportunity to act before something more serious occurs. Think of it as a second chance to protect your health and prevent a potentially life-altering stroke.

 

What Should You Do If You Think You’ve Had a TIA?

  1. Call 911 Immediately

  2. Even if the symptoms go away, treat it as an emergency. Quick action could save your life.

  3. Follow your doctor’s plan and time to make some lifestyle changes.
