Facts about silent strokes

You had a stroke, but to your surprise, you don’t know about it. Is that possible? Yes, silent strokes are like you unknowingly suffering a stroke. But you either don’t remember anything about it or you don’t know it completely.

When it comes to explaining a stroke, we generally think of the causative signs and symptoms. This includes numbness, blurred vision, muttering, facial nerve paralysis, or physical paralysis. However, silent strokes do not cause any symptoms. Therefore, the name – silent stroke or asymptomatic stroke.

Like ischemic stroke, asymptomatic stroke occurs when a part of the brain suddenly stops receiving blood. It stops the supply of oxygen to the brain and causes considerable damage to brain cells. However, silent strokes are difficult to understand because they block the blood supply to parts of the brain that have nothing to do with visible functions such as walking, seeing, or speaking. Therefore, it is overlooked.

So what about silent stroke diagnosis? In most cases, people can only know about a stroke when they have a CT scan or MRI of the brain for other health conditions. That’s when your doctor can confirm that a small part of your brain is damaged to some extent.

Stroke is seen in approximately 5.9% of coronavirus-infected patients in the light of the current scenario with COVID-19. And if you look at the neurological complications of COVID-19, you can see that stroke accounts for about 85% of them.

There are no visible symptoms of silent stroke and it affects only a small part of the brain, but it does not mean less risk or less damage. Brain damage, such as asymptomatic stroke, is cumulative.

Also, if a person experiences several episodes of silent stroke, they may notice the onset of some neurological symptoms, such as poor concentration and memory loss.

According to the American Stroke Association, asymptomatic or asymptomatic strokes are at risk of developing symptomatic strokes in later years. Recent studies have confirmed that multiple episodes of silent stroke are at increased risk of vascular dementia (multiple infarct dementia). Symptoms are:

● The problem of memory and memory loss.

● Loss of control over bladder and bowel movements.
