Silent stroke - Wikipedia

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.

What are the signs of a silent stroke?

Can you have a mini stroke without knowing?

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.

How serious is a silent stroke?

Silent Doesn't Mean Harmless

While silent strokes often pass undetected, the damage they cause can be quite noticeable. Once you suffer from a silent stroke, your chances of suffering from more strokes in the future increase. The damage caused to the brain can result in significant cognitive decline or even death.

What's the difference between a silent stroke and a mini stroke?

If someone has a stroke without realizing it, it's called a silent stroke. Usually, evidence of a silent stroke is found while undergoing a magnetic resonance imaging (MRI) test for another condition. They often do not even remember having any symptoms. A mini-stroke, on the other hand, is a brief but memorable event.

What are the 5 warning signs of a mini-stroke?

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.

Do you always have a stroke after a mini-stroke?

About 1 in 3 people who has a TIA goes on to experience a subsequent stroke. The risk of stroke is especially high within 48 hours after a TIA . The symptoms of a TIA are similar to those of a stroke and include: Numbness or muscle weakness, usually on one side of the body.

What is the treatment for silent strokes?

If a person has a brain scan and their doctor detects one or multiple silent strokes, they may prescribe medications. For instance, blood thinning medications can help to lower blood pressure, and cholesterol medications can help to lower low-density lipoprotein (LDL) cholesterol.

Will a silent stroke show up on a CT scan?

During a silent stroke, an interruption in blood flow destroys areas of cells in a part of the brain that is "silent," meaning that it doesn't control any vital functions. Although the damage will show up on an MRI or CT scan, it's too small to produce any obvious symptoms.

How do they test to see if you had a mini-stroke?

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.

Do mini strokes show up on tests?

Tests will be done to rule out a stroke or other disorders that may cause the symptoms: You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests, but TIAs will not.

How do you test for silent stroke?

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.

Can stress cause silent strokes?

It's known that stress from work is bad for your health, including causing an increase in your risk for cardiovascular disease, particularly high blood pressure and heart disease. If you've wondered specifically if stress can cause a stroke, too, the answer is unfortunately, yes.

Do silent strokes show on MRI?

MRI is best at detecting silent strokes, according to the statement. Its use for brain imaging has gone up dramatically over the years to investigate concerns about memory and cognition, stroke, dizziness, unusual headaches or Parkinson's disease, Gorelick said.

Can silent strokes cause dementia?

But some strokes don't cause any noticeable symptoms. These silent strokes still increase dementia risk. With both silent and apparent strokes, the risk of vascular dementia increases with the number of strokes that occur over time. One type of vascular dementia involving many strokes is called multi-infarct dementia.

What happens days before a stroke?

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.

Can stress cause mini strokes?

Conclusions. Higher levels of stress, hostility and depressive symptoms are associated with significantly increased risk of incident stroke or TIA in middle-aged and older adults.

Should I be worried if I had a mini-stroke?

All types of strokes — including TIAs — require immediate medical attention. Because a TIA may eventually lead to a larger stroke, diagnosis and treatment are important.

Do you stay in the hospital after a mini-stroke?

If a TIA has been confirmed on evaluation and scans, many TIA patients can be discharged home for clinic follow-up within 48 to 96 hours. These dedicated clinics are currently available at M Health Fairview Ridges and M Health Fairview Southdale hospitals.

Can you have a mini-stroke and not go to the hospital?

You do not need to be admitted to hospital because of a TIA, but this is often done because of the absence of an alternative. Many TIA clinics now offer a “one-stop” service for which the patient is assessed, investigated (or investigated before the appointment), and given results at the same session.

How do you feel before a mini-stroke?

What is a pre stroke?

Pre-strokes or mini strokes are the common terms used to describe a transient ischemic attack (TIA). Unlike a full blown stroke, a TIA only lasts a few minutes and does not cause permanent damage. Nevertheless it is a warning sign that a possible stroke may be coming in the future.

What time of day do strokes usually occur?

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).
