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.

Could a silent stroke erode your memory? - Harvard Health

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?

What happens after a silent stroke?

Researchers say that over time, the damage from silent strokes can accumulate, leading to more and more memory problems. "The more brain damage or injury that you have due to these silent strokes, the more difficult it is for the brain to function normally," Dr. Furie says.

What is the difference between a mild stroke and a mini stroke?

A transient ischaemic attack or TIA is also known as a mini-stroke. It is the same as a stroke, except that the symptoms only last for a short amount of time. This is because the blockage that stops the blood getting to your brain is temporary.

Is there a difference between a silent stroke and a mini stroke?

A silent stroke differs from a transient ischemic attack (TIA). In TIA symptoms of stroke are exhibited which may last from a few minutes to 24 hours before resolving. A TIA is a risk factor for having a major stroke and subsequent silent strokes in the future.

TIAs or mini strokes - what are the signs?

What are the after effects of a mini-stroke?

Commonly these included arm and limb weakness or numbness, slurred speech, memory problems, confusion and visual difficulties. In most cases the symptoms improved over time. Some people experienced just one residual symptom, whereas other people had a combination of different ones.

Can you have a mini-stroke and not realize it?

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.

Can doctors tell if you had a mini-stroke?

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.

How serious is a mini-stroke?

TIAs look like strokes in terms of signs and symptoms, but they are temporary. In other words, they leave no lasting brain damage or residual symptoms. However, they serve as a warning sign that a person is at higher risk of a major stroke and should seek immediate medical attention.

What happens if a mini stroke goes untreated?

Even if a major stroke is avoided, repeated mini strokes can have a cumulative negative effect on one's brain health and cognitive function. In severe cases, vascular dementia may result from untreated cerebrovascular events.

How common is silent stroke?

Silent strokes are much more common than strokes that cause classic symptoms such as face drooping, arm weakness and speech difficulty and affect nearly 800,000 Americans each year. According to the statement, one in four people over 80 have one or more silent strokes.

Do mini strokes show up on MRI?

Brain magnetic resonance imaging (MRI) is the preferred and most sensitive modality after transient ischemic attack (TIA) or minor stroke. It should include diffusion-weighted imaging (DWI) and should be completed within 24 hours of symptom onset^1,2; its use is 3-fold.

What causes a mini stroke?

A transient ischaemic attack (TIA) or "mini stroke" is caused by a temporary disruption in the blood supply to part of the brain. The disruption in blood supply results in a lack of oxygen to the brain.

Can silent strokes cause dementia?

Stroke (infarction) blocking a brain artery.

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 are are silent strokes caused by?

A silent stroke is most often caused by reduced blood flow in one of the smaller arteries that feed the brain. It can occur without noticeable symptoms if it affects a part of the brain that doesn't control major movements or vital functions.

What is the life expectancy after a mini-stroke?

At one year after hospitalization, 91.5 percent of TIA patients were still living, compared to 95 percent expected survival in the general population. At five years, survival of TIA patients was 13.2 percent lower than expected -- 67.2 percent were still alive, compared to an expected survival of 77.4 percent.

How long do you stay in the hospital after a mini-stroke?

The typical length of a hospital stay after a stroke is five to seven days. During this time, the stroke care team will evaluate the effects of the stroke, which will determine the rehabilitation plan.

Do mini strokes lead to a major stroke?

June 16, 2005 -- Dutch researchers say minor strokes, or transient ischemic attacks (TIAs), are often followed by other strokes or heart attacks within the next decade.

Are there warning signs days before a stroke?

- 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.
