What Is Brain Stroke?

We often heard about brain stroke and it’s complications and it is a great possibility that we have seen a patient of brain stroke in our life because it is the 3rd leading cause of death after Heart problems and Cancers.

So what is Brain stroke?

A brain stroke is a term given to the condition when blood flow to the brain tissue stops or decreased so that brain parts can not work effectively. There are 2 types of brain stroke.

Types and causes of brain stroke

  1. Ischemic stroke:

When vessels taking blood to the brain occludes, most probably due to a clot in the vessel, then the blood flow to that brain part is stopped or greatly reduced causing Damage or ‘Necrosis’ to that brain part.

  1. Hemorrhagic stroke:

This is the second type of stroke and it happens when a certain artery ruptures most probably due to high blood pressure, causing extravasation ( outside the vessel) of blood, thus blood can not reach its specific destination and that part of the brain will be damaged.

Ischemic stroke is the most common type of stroke and it happens mostly in Obese, old, diabetic, high cholesterol patients. Whereas Hemorrhagic stroke is less common than Ischemic stroke and it happens mostly in patients with uncontrolled high blood pressure.

Symptoms

Having known all these let’s find out how can we know when a person is having a stroke? What are the symptoms of a stroke?

The patient with stroke will experience enormous pain and most of the patients start pointing out to their head and say nothing and some describe the pain as the worst pain of their life.

The other symptoms depend on the area of the brain involved llike.

  1. Loss of speech in damage of Anterior or frontal part of the brain with paralysis to the lower limb.
  2. Loss of apprehension of speech and paralysis of the upper limb and hearing loss in damage to the middle part of the brain.
  3. Loss of vision and balance and fine movements in damage to the posterior part of the brain.

Whenever a person is having a stroke, it is very important to know whether it is Ischemic or Hemorrhagic because treatment to both is different and the wrong diagnosis can lead to crisis.

Treatment

We should look for these symptoms and immediately call for medical help and bring the patient to a nearby hospital because we can do much at home.

Some patients recover fully and some patients lose particular functions of the body depending upon the type, area, time of stroke.

Prevention

We can prevent stroke to happen by controlling our cholesterol and triglyceride levels in the case of Ischemic stroke and by maintaining our blood pressure in case of Hemorrhagic stroke.

A 30-minute walk or some other exercise at least 4 times a week can reduce the chances of both type of stroke significantly. We should adapt a healthy lifestyle to avoid these deadly diseases.
