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.
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.
Is it possible to have a stroke and not know it? Yes. You can have a “silent” stroke, or one you're completely unaware of or can't remember. When we think of strokes, we often think of symptoms like slurred speech, numbness, or loss of movement in the face or body.
Most people who have a mini-stroke feel fine after the event. In fact, many people don't even realize they've had one! Symptoms might include weakness, numbness, tingling, vision changes or difficulty speaking. Most symptoms are temporary and dissipate within minutes but sometimes can last up to 24 hours.
Silent Doesn't Mean Harmless
The damage caused to the brain can result in significant cognitive decline or even death. It may also lead to vascular dementia. The damage that happens is permanent, but through therapy and healthy habits, stroke survivors may be able to reduce the effects and prevent future strokes.
Sometimes a stroke happens gradually, but you're likely to have one or more sudden symptoms like these: Numbness or weakness in your face, arm, or leg, especially on one side. Confusion or trouble understanding other people. Difficulty speaking.
In fact, ischemic strokes unfold over a period of 10 hours. That means that with every second you wait for treatment, the brain damage gets worse. If a stroke is untreated for the full 10 hours, the brain ages up to 36 years! With every minute you wait, the brain loses two million brain cells.
If a stroke is suspected, a CT scan is usually able to show whether you have had an ischaemic stroke or a haemorrhagic stroke. It's generally quicker than an MRI scan and can mean you're able to receive appropriate treatment sooner.
The only way to tell the difference between a ministroke and a stroke is by having a doctor look at an image of your brain with either a CT scan or an MRI scan. If you've had an ischemic stroke, it's likely that it won't show up on a CT scan of your brain for 24 to 48 hours. An MRI scan usually shows a stroke sooner.
ASA suggests calling emergency medical services as soon as possible, even if symptoms quickly fade. A TIA precedes about 15 percent of full-fledged strokes, and people who have experienced a TIA are at an increased risk of having a stroke within three months. “Ignoring any stroke sign could be a deadly mistake,” Dr.
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.
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.
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).
Numbness or weakness in your face, arm, or leg, especially on one side. Confusion or trouble understanding other people. Difficulty speaking. Trouble seeing with one or both eyes.
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.
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.
Stroke symptoms usually come on suddenly -- in minutes to an hour. There is usually no pain associated with the symptoms. The symptoms may come and go, go away totally, or get worse over the course of several hours.
The first stage is flaccidity , and occurs immediately post-stroke. Muscles will be weak, limp, or even "floppy." Because a stroke often affects one side more than the other, this flaccidity may be limited to just one side.
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.
