Frequently Asked Questions
What is the difference between a TIA and a full stroke?
Both a transient ischemic attack and an ischemic stroke are caused by a clot that blocks blood flow to a portion of the brain. The primary difference lies in the duration and the permanence of the damage. In a TIA, the clot naturally dissolves or dislodges on its own, usually within a few minutes to an hour, and the symptoms disappear without leaving permanent, visible brain tissue damage on a standard MRI. In a full stroke, the blockage persists long enough to cause localized brain cell death, leading to long-lasting or permanent physical and cognitive impairments.
If my symptoms completely disappear after ten minutes, do I still need to go to the hospital?
Absolutely. The complete resolution of symptoms is the defining characteristic of a TIA, but it does not mean the underlying danger has passed. A TIA is a blaring siren indicating that the vascular environment in your brain is primed for a major, devastating stroke. Medical professionals refer to a TIA as a harbinger event. By going to the emergency room immediately, doctors can perform vascular imaging, check your carotid arteries, evaluate your heart rhythm, and start you on preventive medications that drastically reduce your risk of a major stroke in the near future.
How can I lower my risk of experiencing a transient ischemic attack?
Protecting your vascular health is the most effective way to prevent a TIA. Monitor and manage your blood pressure, as hypertension is the leading cause of cerebrovascular issues. Work with your healthcare provider to keep your cholesterol and blood sugar levels within healthy ranges. Embrace a heart-healthy diet rich in leafy greens, lean proteins, and omega-3 fatty acids. Engage in regular cardiovascular exercise, such as brisk walking, swimming, or cycling, to keep your arteries flexible and clear. Finally, if you smoke, seek resources to quit immediately, as smoking significantly damages your blood vessels.
What should I do while waiting for the ambulance to arrive?
If you suspect you or a loved one is experiencing a TIA, call 911 immediately and clearly state that you suspect a stroke. Have the person lie down in a safe, comfortable position to prevent falls and ease blood flow to the brain. Do not offer any food, water, or medication—especially aspirin—unless explicitly instructed to do so by the emergency dispatcher. Because some strokes are hemorrhagic (caused by bleeding), taking a blood thinner like aspirin without a proper diagnosis could worsen the situation. Stay calm, unlock the front door for the paramedics, and gather all current medication bottles so the medical team can review them upon arrival.
