Hope you all keeping fine. We went a through brief introduction about stroke in our last edition. Stroke is as dangerous as any other life threatening disease and can occur at a very young age too.
You have heard the term over and over again but you still wonder: What is stroke anyway? Stroke is a sudden impairment in brain function. One may suffer an inability to speak or speak clearly, walk, or move a limb because blood has stopped flowing to an area of the brain. Usually, this is caused by the blockage, or the rupture, of a blood vessel.
Unlike mini strokes, which are also known as transient ischemic attacks (TIA), whose symptoms resolve on their own in less than 24 hours, strokes leave behind long-lasting neurological impairments. The severity of these impairments depends on how large the damage is to the brain, and on the part of the brain that is affected.
What is the difference between silent stroke and mini stroke? Silent strokes and mini strokes are minor vascular events which can forecast that a large stroke is coming.
Although they sound similar, silent stroke and Mini stroke relatively different types of strokes.
A silent stroke is found incidentally on an MRI of the brain. When patients are asked whether they remember having a stroke, they are often surprised and cannot recall feeling any symptoms of stroke at any point in their lives. One study showed that by the age of 69, approximately 10% to 11% of people who consider themselves stroke-free have suffered at least one stroke that can be seen on MRI.
A mini stroke, on the other hand, is a brief, but discrete and certainly memorable clinical event, in which a person develops the symptoms of a stroke for a few minutes to a few hours. By definition, the symptoms of a mini stroke disappear in less than 24 hours. The alternate name doctors use for mini strokes is transient ischemic attacks, or TIAs.
Why do strokes usually affect only one side of the body?
For the most part, the left side of the brain controls the right side of the body while the right side of the brain controls the left side of the body. When a blood vessel that carries blood to a given part of the brain is blocked, only the side of the brain where the blood vessel is located is affected. This causes symptoms in the opposite side of the body
The Habit that can cause a stroke:
Smoking
Drinking
Birth control pills
Hypertensions
I hope this edition had helped you to understand what is Stroke. So guys, take good care, as we can not avoid the deaths but sure we can limit the causes by taking simple precautions handy. See you all in the next edition till then live life and do remember to donate BLOOD…. J
