Brain Stroke!

What is a Stroke?

A Stroke is also known as a brain attack happens; when the blood flow to the brain stops. Even if it's for a second it is one of the most common causes of natural fatality and the leading cause of preventable disability. But the critical question is what causes stroke in the first place? Well for that first it's essential to know a little something about our brain.

You see our brain makes up just two percent of our body's mass. But as it runs your nervous system, it consumes around 20 percent or about a fifth of the total oxygen in your blood. But this oxygen is sent to the brain through a system of arteries (carotid). 

Arteries supply oxygen to the front side of the brain while vertebral arteries supply the oxygen to the back but it's essential to know that this oxygen is carried to the brain by our blood vessels. So, in case the blood flow stops, the 

brain cells begin to die; 

leading to brain stroke which can happen in two ways namely the Hemorrhagic stroke and the Ischemia stroke.

In Hemorrhagic stroke a blood vessel 

breaks flooding the brain with blood and damaging brain cells. Whereas in Ischemia a clot in the arteries blocks the blood supply from reaching the brain. But the vital question is where do these clots come from?

Well in some cases, a sudden change in 

heartbeats prevents the upper chamber of the heart from contracting normally. This change in rhythm slows down the blood pressure which allows things like vibrant platelets and clotting factors to stick together and become a lump.

This lump can get into the arteries 

supplying blood and oxygen to the brain. And if the clot is big enough, it can get stuck on the way; cutting the blood supply and no blood supply means no oxygen can reach the brain. And as the brain does not have pain receptors the person does not feel the blockage. But this lack of oxygen begins to affect brain functions and depending on the area of stroke. 

The person will show certain symptoms like slurred speech blurred vision and sudden weakness often in just one side of the body and if no help arrives on time the brain cells will start to die leading to brain damage that may be severe or permanent.

That's why, if you see anyone with sad 

symptoms consider it as a medical emergency and take them to the hospital ASAP. Over there the doctor will give them a medication called tissue plasminogen activator, that can break apart the blood clot and allow blood supply like before if given on time.

This medication can decrease the chances of getting a stroke. And if for some reason the patient can't be given the drug then the doctor can perform surgery to remove the clot from the affected artery.

Remember my friends' 

stroke can happen to anyone. So it's essential to stay healthy by eating well, exercising regularly, and meditating to reduce stress.

Random FACT:

Someone in the world has a 

stroke every two seconds and about 87 of all strokes are Ischemic strokes.

I hope you learned something critical 

today until next time Goodbye and Take care.
