Yes, doctors can often tell if you've had a mini-stroke (TIA) through a combination of your symptoms, medical history, physical exams, and diagnostic tests like MRI/CT scans and ultrasounds, though diagnosing it definitively after symptoms resolve can be tricky; a key difference is that a TIA won't show permanent brain damage on imaging, but it's still a serious warning sign for a future stroke, so urgent medical attention is crucial.
A magnetic resonance imaging (MRI) scan is the preferred way to rule out brain injury (i.e., a stroke), ideally done within 24 hours of when symptoms began. About 40% of patients presenting in the ER with TIA symptoms will actually be diagnosed with a stroke based on MRI results.
Most symptoms of a TIA happen suddenly and usually go away within an hour, although they may last for up to 24 hours. Symptoms can include: Numbness or weakness in the face, arm, or leg, especially on one side of the body.
This can cause sudden symptoms similar to a stroke, such as speech and visual disturbance, and numbness or weakness in the face, arms and legs. But a TIA does not last as long as a stroke. The effects last a few minutes to a few hours and fully resolve within 24 hours.
Other signs and symptoms may include:
In around a third of assessed cases, the symptoms aren't due to a stroke or TIA (transient ischaemic attack). The person will have more checks and tests to find out what's wrong. Some of the most common stroke mimics are seizures, migraine, fainting, serious infections and functional neurological disorder (FND).
There may be no warning signs or noticeable symptoms leading up to this, and many people do not realize they experienced a silent stroke until they undergo a brain scan. Because silent strokes do not produce the common symptoms associated with other strokes, this cardiac event can be easily overlooked or dismissed.
What Not to Do After a Mini Stroke:
You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests, but TIAs will not. You may have an angiogram, CT angiogram, or MR angiogram to see which blood vessel is blocked or bleeding. You may have an echocardiogram if your provider thinks you may have a blood clot from the heart.
Diagnosing a TIA stroke
Often symptoms have ended by the time paramedics arrive. A video of the symptoms will help doctors make a diagnosis. Tests done to help investigate a TIA can include blood tests, heart rhythm monitoring (an electrocardiogram or ECG) or a brain scan.
It's caused by a brief blockage of blood flow to the brain. A TIA usually lasts only a few minutes and doesn't cause long-term damage.
Departments that treat this condition
What happens if a TIA goes untreated? Having a TIA is a warning you are at risk of having a stroke. If you do not seek urgent medical help, you may go on to have another TIA or a stroke. So it's important to get treatment as soon as possible to reduce your risk.
Presently the diagnosis of ischemic stroke relies on clinical assessment in combination with neuroimaging. Physicians are very good at diagnosing stroke, therefore the use of a blood test to diagnose stroke is generally limited to specific scenarios where time and/or imaging resources are limited.
A diagnosis of TIA can only be determined after an assessment by a health care provider, which can include blood tests, X-rays, ultrasound scanning, a magnetic resonance imaging (MRI), a computed tomography (CT) scan and tests to find out whether there are heart-related problems, such as an irregular heartbeat.
A neurologist will monitor progress, adjust medications, recommend imaging and lab tests, and help patients and their families understand the impact of the stroke and the recovery process. Stroke survivors often face cognitive, emotional, and physical challenges, all of which neurologists are trained to manage.
Some people get fatigue (extreme tiredness which does not always get better with rest) after a TIA. This could affect you going back to work after a TIA or limit how much you can do around the house. Make others aware of how you are feeling and any support you might need.
Behaviors that can increase risk
Talk with your health care team about making changes to your lifestyle. Eating a diet high in saturated fats, trans fat, and cholesterol has been linked to stroke and related conditions, such as heart disease.
The warning signs include weakness or numbness that is typically isolated to one side of the body, slurred speech, dizziness and loss of vision. Ministroke symptoms occur suddenly and generally without any warning. They may last for only a few minutes or persist for up to 24 hours.
Get emergency treatment right away. Even if symptoms subside, you should be evaluated at a hospital, since a mild stroke can be a signal that a potentially more serious stroke is on its way. After being released from the hospital, follow up with your doctor to be screened for hidden problems.
Some studies have shown a relationship between stress, negative emotions (such as depression or hostility), and risk of TIA or stroke.
Imaging scans. Healthcare providers can get a computed tomography (CT) scan in only a few minutes. It helps them to quickly see if you're having a brain bleed or not and, if so, provide treatment immediately. An MRI scan helps your care team tell if you had a stroke or a TIA.
Posterior circulation stroke affects around 20% of all ischemic strokes and can potentially be identified by evaluating or assessing the “Five D's”: Dizziness, drowsiness, dysarthria, diplopia, and dysphagia.
So-called transient ischemic attacks can eventually lead to cognitive declines as steep as those following a full-on stroke, new research finds. Kristin Kramer woke up early on a Tuesday morning 10 years ago because one of her dogs needed to go out.
Your healthcare professional recommends a medicine based on what caused the TIA , where it was located, its type and how bad the blockage was. Your healthcare professional may prescribe: Anti-platelet drugs. These medicines make a circulating blood cell called platelets less likely to stick together.
