Many strokes occur without a recognizable warning period.

Some people experience a TIA before a major stroke, but the timing varies. A TIA may occur hours, days, or longer before a subsequent stroke, and many people with stroke do not experience a preceding TIA at all.

Therefore, don't use a calendar-based rule such as “I have one month before something happens.”

Instead, focus on the sudden appearance of neurological symptoms.

If they occur, act immediately.

How Can You Reduce Stroke Risk?

Although not every stroke can be prevented, several major risk factors can be managed.

Keep your blood pressure under control. Hypertension is one of the most important modifiable risk factors for stroke.

Manage diabetes and blood glucose when applicable.

Have your cholesterol evaluated and treated when necessary.

Avoid smoking and tobacco products.

Maintain regular physical activity and follow a balanced eating pattern rich in vegetables, fruits, whole grains, legumes, and other minimally processed foods.

If you have atrial fibrillation or another condition that increases the risk of blood clots, follow your healthcare professional's treatment plan carefully.

Take prescribed medications consistently and do not stop blood-pressure, cholesterol, or blood-thinning medication without medical advice.

The Bottom Line

A stroke does not necessarily announce itself weeks in advance. The most important warning signs are usually sudden neurological changes, including facial drooping, one-sided weakness or numbness, speech difficulty, vision problems, severe balance problems, confusion, or an unusually severe sudden headache.

A TIA can produce similar symptoms that disappear, but that does not make the event harmless.

If you or someone near you suddenly develops possible stroke symptoms, do not wait to see whether they improve. Treat it as an emergency.

Remember:

FACE — ARM — SPEECH — TIME.

The faster a stroke is recognized and treated, the better the chance of limiting brain injury and improving the outcome.
