Recognizing a Transient Ischemic Attack (TIA): 5 Warning Signs of a “Mini-Stroke”
4. Sudden, Temporary Vision Changes
Because the optic pathways travel deeply through the brain, blood flow restrictions can instantly disrupt how the eyes process images.
- What to Look For: The individual may experience sudden double vision, intense blurriness, or a complete loss of sight in one or both eyes. A classic symptom of a TIA is a condition called amaurosis fugax, where the person describes a dark shade or curtain temporarily falling across their field of vision before lifting a few minutes later.
5. Sudden Loss of Balance or Severe Dizziness
If the temporary ischemia occurs near the cerebellum or brainstem—the regions responsible for balance and spatial orientation—the body loses its anchoring mechanics.
- What to Look For: The older adult may suddenly stumble, sway heavily to one side, or experience acute vertigo (the sensation that the room is spinning violently). This is often accompanied by an unexplained, sudden lack of physical coordination or a completely unprovoked fall.
The Lifesaving Response: Use the B.E. F.A.S.T. Protocol
To make these five signs unforgettable for your audience, medical professionals worldwide utilize the simple B.E. F.A.S.T. acronym. If you notice any of these signs—even if they vanish completely after 60 seconds—you must treat it as a strict medical emergency.
B - Balance Loss | E - Eye Blur | F - Face Droop | A - Arm Drift | S - Speech Slur | T - Time to Call 911
- B – BALANCE: Is there a sudden loss of balance, unsteady walking, or coordinate failure?
- E – EYES: Is there sudden double vision, blurriness, or partial blindness in one eye?
- F – FACE: Ask the person to smile. Does one side of the face droop down?
- A – ARMS: Ask them to raise both arms. Does one arm naturally drift or fall downward?
- S – SPEECH: Ask them to repeat a simple phrase. Is their speech slurred, strange, or completely absent?
- T – TIME: If you answer “Yes” to any single one of these checks, Time is critical. Call 911 or localized emergency services immediately.
