That headline is meant to grab attention, but the underlying message has some truth: many strokes can be prevented by managing known risk factors.
A silent stroke (sometimes called a “quiet stroke”) is a stroke that damages the brain without causing the classic, obvious symptoms of a major stroke. People may not know they’ve had one until it’s shows up on a brain scan or they develop subtle problems with memory, thinking, or walking.
Habits that can lower your stroke risk
- Control your blood pressure. This is the single most important step.
- Stay physically active. Aim for at least 150 minutes of moderate exercise per week, if your healthcare provider says it’s appropriate.
- Eat a heart-healthy diet rich in fruits, vegetables, whole grains, legumes, and healthy fats, while limiting excess salt and highly processed foods.
- Don’t smoke, and avoid secondhand smoke.
- Limit alcohol if you drink.
- Manage diabetes and high cholesterol if you have them.
- Maintain a healthy weight.
- Get adequate sleep, and seek evaluation if you have symptoms of sleep apnea (such as loud snoring and excessive daytime sleepiness).
- Take prescribed medications consistently for conditions like high blood pressure, diabetes, high cholesterol, or irregular heart rhythms.
Know the warning signs of a stroke
Even if silent strokes can go unnoticed, a typical stroke is a medical emergency. Remember FAST:
- Face: One side of the face droops.
- Arms: One arm is weak or numb.
- Speech: Speech is slurred or difficult.
- Time: Call your local emergency services immediately.
Also seek emergency care if someone suddenly develops vision loss, severe dizziness, difficulty walking, confusion, or a sudden severe headache.
The headline exaggerates the mystery, but the prevention advice is straightforward: controlling blood pressure, living a heart-healthy lifestyle, and recognizing stroke symptoms are the most effective ways to reduce your risk.
