Generally, minor stroke symptoms won't rouse you from sleep. But when people do wake up after a stroke, they notice something is amiss. The symptoms depend on both the severity of the stroke and the region of the brain it damaged. Perhaps one leg does not seem to work well, or an arm feels weak.
Signs and Symptoms of a Stroke
Facial drooping, often only on one side. Arm or leg weakness. Speech difficulties. Dizziness.
Background It is reported that 13% to 44% of all cerebrovascular accidents (CVAs) occur during sleep. In addition to other well-known risk factors, snoring, sleep apnea, obesity, and daytime sleepiness have been shown to significantly increase the risk of stroke.
Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body. Sudden confusion, trouble speaking, or difficulty understanding speech. Sudden trouble seeing in one or both eyes. Sudden trouble walking, dizziness, loss of balance, or lack of coordination.
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.
Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke. One study found that 43% of stroke patients experienced mini-stroke symptoms up to a week before they had a major stroke.
You get stroke symptoms because a clot is blocking the blood supply in your brain. When the clot moves away, the stroke symptoms stop. You might feel like you're fine afterwards, but it's vital to get medical help right away.
Wake-up stroke is a stroke that happens in your sleep. The definition of a wake-up stroke is one where a patient wakes up with stroke symptoms that were not present prior to falling asleep. It is estimated that 20 per cent, or one in five of all strokes are wake-up strokes.
Wake-up stroke, defined as the situation where a patient awakens with stroke symptoms that were not present prior to falling asleep, represents roughly 1 in 5 acute ischemic strokes and remains a therapeutic dilemma.
Is it possible to have a stroke and not know it, like if you're sleeping or the symptoms are mild? Answer from Ted Lowenkopf, M.D., medical director of Providence Stroke Center: Yes, you can have a stroke and not know it.
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.
Drink a lot of water: You should drink at least five glasses of water per day, and this will reduce your risk of stroke by 53%, according to a recent study by Loma Linda University.
There are two main causes of stroke: a blocked artery (ischemic stroke) or leaking or bursting of a blood vessel (hemorrhagic stroke). Some people may have only a temporary disruption of blood flow to the brain, known as a transient ischemic attack (TIA), that doesn't cause lasting symptoms.
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).
Age. The older you are, the more likely you are to have a stroke. The chance of having a stroke about doubles every 10 years after age 55. Although stroke is common among older adults, many people younger than 65 years also have strokes.
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.
Symptoms include:
One-sided arm or leg weakness. Slurred speech or dysarthria. Double vision or other vision problems. A headache.
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.
Computerized tomography (CT) scan – CT scans use a series of X-rays to create a detailed image of your brain. A CT scan can show a hemorrhage, tumor, stroke and other conditions. There are different types of CT scans that your doctor may use depending on your situation.
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.
