There is no blood test that can diagnose a stroke. However, in the hospital, your doctor or nurse may do a series of blood tests to learn the cause of your stroke symptoms: Complete blood count (CBC).
Brain scans
Computerised tomography (CT scan) and magnetic resonance imaging (MRI) take pictures of your brain that show areas of damage and swelling. Either a CT scan or MRI should be done urgently within the first 24 hours after a stroke. This is to work out the type of stroke (ischaemic or haemorrhagic).
Call 9-1-1 immediately if any of these signs of stroke appear: Numbness or weakness in the face, arm, or leg; Confusion or trouble speaking or understanding speech; Trouble seeing in one or both eyes; Trouble walking, dizziness, or problems with balance; severe headache with no known cause.
Can an ECG detect stroke? Yes. ECG can detect a heart problem that might lead to a stroke or even uncover a past problem such as a previous heart attack.
Symptoms can be subtle and fleeting: They typically last less than an hour. The advice for these milder events is the same: Call 911, right away, for urgent evaluation and care. If you have a mild stroke or TIA, do not assume that you have dodged the bullet.
Brain scans and tests
You should have a brain scan soon after symptoms start, within an hour of arriving at hospital if possible. The scan can show whether the stroke is due to a clot or a bleed. There are two main types of scan used: A computed tomography or CT scan.
The major risk factors for stroke include: High blood pressure. Diabetes. Heart and blood vessel diseases: Conditions that can cause blood clots or other blockages include coronary heart disease, atrial fibrillation, heart valve disease, and carotid artery disease.
What is Pre-Stroke? Sometimes, there is a smaller, temporary clot that is quickly resolved, though the symptoms will be similar thanks to the effect such clots have on the brain. This is known as a Transient Ischemic Attack (TIA) or “Pre-Stroke,” and often points to a more life-threatening attack on its way.
Stress can cause the heart to work harder, increase blood pressure, and increase sugar and fat levels in the blood. These things, in turn, can increase the risk of clots forming and travelling to the heart or brain, causing a heart attack or stroke.
Regardless of the size of your stroke, it's important to participate in rehabilitation in order to maximize your chances of recovery. With a rigorous therapy regimen, most mild stroke survivors can achieve a full recovery, or get very close to one.
A silent stroke refers to a stroke that doesn't cause any noticeable symptoms. Most strokes are caused by a clot that blocks a blood vessel in the brain. The blockage prevents blood and oxygen from reaching that area, causing nearby brain cells to die.
A person experiencing a TIA might feel sudden weakness or numbness on one side of the body, have slurred speech, have trouble seeing or talking, and feel confused. The person may experience a combination of these symptoms at the same time.
Although stroke is common among older adults, many people younger than 65 years also have strokes. In fact, about one in seven strokes occur in adolescents and young adults ages 15 to 49. Experts think younger people are having more strokes because more young people have obesity, high blood pressure, and diabetes.
Call 911 or emergency medical services if your blood pressure is 180/120 mm Hg or greater and you have chest pain, shortness of breath, or symptoms of stroke. Stroke symptoms include numbness or tingling, trouble speaking, or changes in vision.
The role of cardiologists in the early diagnosis of stroke (first few hours) is minimal. However, cardiologists should play an important role during the subsequent hours to days, when early recognition of potential underlying and/or associated cardiac disease may contribute to the aetiologic diagnosis of stroke.
It can be caused by a narrowed blood vessel, bleeding, or a clot that blocks blood flow.
Some people have strokes without realizing it. They're called silent strokes, and they either have no easy-to-recognize symptoms, or you don't remember them. But they do cause permanent damage in your brain. If you've had more than one silent stroke, you may have thinking and memory problems.
There is no blood test that can diagnose a stroke. However, in the hospital, your doctor or nurse may do a series of blood tests to learn the cause of your stroke symptoms: Complete blood count (CBC).
If you have a silent stroke, you probably won't know it unless you happen to have a brain scan and the damage shows up. You may have slight memory problems or a little difficulty getting around. A doctor may be able to see signs of silent strokes without testing.
