8 Warning Signs of Stroke That May Appear Beforehand — and 9 Tips to Help Prevent It

A stroke can happen suddenly, but some people may experience warning signs or “mini-strokes” (transient ischemic attacks, or TIAs) before a major stroke. A TIA occurs when blood flow to part of the brain is briefly interrupted and symptoms may disappear within minutes or hours. It is still a medical emergency because it can signal a higher risk of a future stroke.

8 Possible Warning Signs That Should Not Be Ignored

1. Sudden weakness or numbness

• Weakness, tingling, or numbness—especially on one side of the face, arm, or leg—can be a warning sign.

2. Trouble speaking or understanding speech

• Slurred speech, difficulty finding words, or confusion may indicate a problem with brain blood flow.

3. Sudden vision changes

• Blurred vision, double vision, or loss of vision in one or both eyes requires urgent evaluation.

4. Dizziness or loss of balance

• Sudden trouble walking, coordination problems, or severe dizziness can be stroke-related.

5. A sudden severe headache

• A sudden, unusual headache—especially one described as the “worst headache ever”—may be a warning sign.

6. Facial drooping

• One side of the face may droop or feel numb. A simple check is to smile and see whether both sides move normally.

7. Episodes of confusion or unusual behavior

• Sudden difficulty understanding situations or performing familiar tasks can be concerning.

8. Brief symptoms that disappear

• Symptoms that go away after a short time may be a TIA (“mini-stroke”) and should still be checked urgently.

Remember the FAST Stroke Check

F — Face: Does one side droop?
A — Arms: Can both arms be raised evenly?
S — Speech: Is speech strange or unclear?
T — Time: Call emergency services immediately if these signs appear.

9 Tips to Help Reduce Stroke Risk

1. Control blood pressure

High blood pressure is one of the biggest risk factors for stroke. Check it regularly and follow prescribed treatment.

2. Manage cholesterol levels

High LDL (“bad”) cholesterol can contribute to artery narrowing.

3. Stop smoking

Smoking damages blood vessels and significantly increases stroke risk.

4. Stay physically active

Regular movement helps improve circulation and supports heart health. Even daily walking can help.

5. Eat a heart-healthy diet

Focus on:

• Vegetables and fruits
• Whole grains
• Beans and nuts
• Lean proteins
• Less processed and high-salt foods

6. Maintain a healthy weight

A healthy weight can improve blood pressure, cholesterol, and blood sugar control.

7. Manage diabetes

High blood sugar can damage blood vessels and increase stroke risk.

8. Limit alcohol

Heavy alcohol use can raise blood pressure and increase stroke
