one-sided weakness. vision changes or loss of peripheral vision: "If you have a stroke on the back of the brain, you'll have a visual field cut on one side of your eyesight," explained Griffith. loss of coordination, unsteady gate, dizziness. sudden onset of nausea and vomiting.
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.
Weakness or numbness of the face, arm or leg, usually on one side of the body. Trouble speaking or understanding. Problems with vision, such as dimness or loss of vision in one or both eyes. Dizziness or problems with balance or coordination.
Ischemic stroke may be associated with hereditary and acquired blood clotting disorders. These are uncommon. Sickle cell disease (also called sickle cell anemia) – A genetic disorder that causes abnormal hemoglobin (the substance in red blood cells that carries oxygen to all the body's organs).
Eyes. Sudden trouble seeing out of one or both eyes should also be taken seriously and could be another possible sign of stroke. Dr. Laali said that problems with vision can be one of the more overlooked symptoms, because it's not as readily known to the general public as a potential sign of stroke.
What does that mean? A. 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.
Sudden dizziness, loss of balance or coordination. Loss of vision or changes to your vision in one or both eyes, which usually happens suddenly. Feeling confused or having trouble understanding things that are usually easy for you. Numbness or weakness on one side of the body (or in one arm or leg)
In addition to the classic stroke symptoms associated with the FAST acronym, around 7-65% of people undergoing a stroke will experience some form of a headache. People describe a stroke-related headache as a very severe headache that comes on within seconds or minutes.
One of the most common stroke mimics is a seizure, which researchers believe account for as many as 20% of all stroke mimics. Other common stroke mimics include migraines, syncope, sepsis, brain tumor and metabolic derangement (low sodium or low blood sugar).
Warning signs of an ischemic stroke may be evident as early as seven days before an attack and require urgent treatment to prevent serious damage to the brain, according to a study of stroke patients published in the March 8, 2005 issue of Neurology, the scientific journal of the American Academy of Neurology.
Yes, you can have a stroke and not know it. A stroke's effects can be undetectable if the stroke is small or if the tissue damaged does not serve a critical function. Evidence of the stroke would show on a CT scan or an MRI of the brain, but it might not produce symptoms.
Symptoms of a TIA come on suddenly. You may feel perfectly fine one minute and then suddenly develop difficulty speaking or moving one side of your body. Sometimes the symptoms will come and go several times in a short period of time.
Blood tests for stroke. 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).
An MRI scan is most often used. This type of scan uses a strong magnetic field and radio waves to create an image of your brain.
Unfortunately, most people don't actually find out they've suffered from a silent stroke until they see a doctor for another condition and are ordered to have an MRI or a CT scan. At that point, their doctor may notice small areas of damage in the brain indicating a silent stroke.
Weakness, numbness or paralysis in the face, arm or leg, typically on one side of the body. Slurred or garbled speech or difficulty understanding others. Blindness in one or both eyes or double vision. Vertigo or loss of balance or coordination.
Look for these signs and symptoms if you think you or someone you know is having a stroke: Sudden trouble speaking and understanding what others are saying. Paralysis or numbness of the face, arm or leg on one side of the body. Problems seeing in one or both eyes, trouble walking, and a loss of balance.
There is an evident association between both acute and chronic emotional stress and risk of stroke.
A brain CT scan can show if there is bleeding in the brain or damage to the brain cells from a stroke. Magnetic resonance imaging (MRI) uses magnets and radio waves to create pictures of your brain. An MRI may be used instead of—or in addition to—a CT scan to diagnose a stroke.
Note the time you first see symptoms
A clot-busting medication called tPA, or tissue plasminogen activator, can be given to someone if they're having a stroke, potentially reversing or stopping symptoms from developing.
This meta-analysis of 11 816 strokes provides strong evidence that the onset of stroke symptoms has a circadian variation, with a higher risk in the early morning hours (6 am to noon), and lower risk during the nighttime period (midnight to 6 am).
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.
Usually, a silent stroke is discovered unexpectedly on a brain CT or brain MRI. These imaging tests can easily distinguish past strokes from recent strokes.
Any irregularities or causes for concern show up in a CT scan approximately six to eight hours after the onset of the first signs of a stroke. During a CT scan, the patient may be intravenously injected with dyes, which will highlight any abnormal areas in the scan, giving doctors a clearer view of the head.
