This video explains about stroke. By the end
of this video you will be come to know about 1. What is stroke ?
2. Symptoms of stroke. 3. Diagnosis and Tests
4. Treatment 5. Prevention and Risk Factors 1. What is stroke ? Stroke, in some countries it is better known
as paralysis stroke, Brain attack, cerebrovascular accident (CVA) or cerebrovascular insult (CVI). As per World Health Organization (WHO)
There are 15 million people who suffer from stroke worldwide each year and more than 12.7
million strokes worldwide are due to High blood pressure. So what exactly stroke is ? As per WHO : A stroke is caused by the interruption
of the blood supply to the brain, usually because a blood vessel bursts or is blocked
by a clot. This cuts off the supply of oxygen and nutrients, causing damage to the brain
tissue. There are three major types of strokes:
1. Ischemic stroke 2. Hemorrhagic stroke
3. Transient Ischemic stroke Ischemic stroke
Basically ischemia is an state that represents an inadequate blood supply to an organ or
part of the body. So ischemic stroke occurs due to interruption
of blood supply to brain cells leading to dysfunction of brain tissues. This happen
as a blood clot interrupt the blood supply. This is the most common stroke that is around
85% of strokes. Hemorrhagic Stroke
Basically hemorrhage means an escape of blood from a ruptured blood vessel.
So when there is any rupture in blood vessel and the blood damages the brain cells and
Hemorrhagic Stroke occurs. Transient Ischemic stroke (TIA) Sometimes
symptoms of stroke disappear within 24 hrs. that is called Transient Ischemic stroke 2. What are the symptoms of stroke
The patient may feel 1. problem in speaking or understanding,
2. inability to move or feel, 3. drooping face,
4. weakness in arm or legs, 5. changes to vision,
6. loss of memory. For easy understanding just remember
FAST Face : is there any distortion in face
Arm : can you lift your both hands Speech : can you speak properly
Time : if you notice any one of these symptoms, it’s time to go to doctor without wasting

As soon as you reach the doctor, you are diagnosed with various methods.
1. Medical history and physical Examination The very first thing doctor will ask about
your medical history as high blood pressure, smoking, family or personal history of stroke
and heart disease. Next the doctor performs a physical check.
He may check numbness on your body in addition to that doctor may check your mental alertness
and your balance and coordination. Your blood test may also be done. 2. Diagnostic Tests
Later doctor may perform any or more diagnostic tests as: 1. Computed Tomography (CT) Scan of Brain
This produces a detail picture of injury. The test is painless. The test can show the
areas of stroke having blood clots. 2. Magnetic Resonance Imaging (MRI) With the
help of magnetic and radio waves MRI creates an image of brain to find out the injury.
It can detect the damage to brain tissues. 3. Carotid ultrasound may be performed from
to check the blood flow in carotid arteries and any plaque can be detected.
4. Carotid Angiography In order to receive a more detail of damage brain tissues, a dye
is injected to blood vessels. This dye makes artery more visible to the x-rays. 3. Heart Tests
1. Echocardiogram and Electrocardiogram : These tests provides necessary data of your heart
as size and shape of heart. How well valves and chambers are working. They can detect
any clot present in heart, that may cause stroke. 4. Treatment
1. Emergency treatment 1.a Ischemic stroke: Action will be taken
to steady your important signs as giving you medicines like aspirin or another antiplatelet
medicine. 1.b Hemorrhagic stroke: In case of hemorrhagic
stroke, main focus is to control bleeding, lower the blood pressure in the brain, and
make steady your important parameters as blood pressure in brain as well. If there is bleeding
due to a ruptured brain aneurysm, you may be operated to repair the aneurysm followed
by you will be given clot dissolving medicines. 2. Thrombolysis: Thrombolysis is also called
thrombolytic therapy. Thrombolytic therapy is a treatment to dissolve blood clots vessels,
prevent damage to tissues and organs and to improve blood flow.
3. Medications: A variety of medicines are used for the people who are at high risk of
having stroke. 4. Surgery: You may need surgery, if you have
had a stroke. 5. Prevention and Risk Factors
Prevention is better than cure so follow these steps to prevent the stroke.
1. No alcohol 2. Healthy diet
3. No smoking 4. Exercise daily
5. Keep control on blood pressure 6. Control diabetes
7. Lowering cholesterol
