STROKE :

Health Careers Institute

A stroke is also called a cerebro-vascular accident.Strokes happen when there is poor blood flow to your brain that results in cell death within minutes.

Two kinds of stroke - Ischemic stroke | Hemorrhagic stroke

• An ischemic stroke is caused by a blood clot that blocks a blood vessel in the brain, and causes dysfunction of the brain tissue in that area.

• A hemorrhagic stroke is less common and is caused by a blood vessel that breaks and bleeds into the brain.

TYPES AND CAUSES:

DIAGNOSIS :

• If any of symptoms or signs are observed, contact emergency services immediately.

• Doctors will examine the patient , check blood pressure and examine the carotid

arteries in the neck and the blood vessels at the back of the eyes.

• Blood tests will be carried out to find out blood clots & the levels of substances in

the blood

• CT scans will be taken of the brain.

• MRI scans can detect damaged brain tissue.

• An ultrasound may be taken to check the blood flow in the carotid arteries.

• An echocardiogram creates a detailed image of the heart in order to check for any

sources of clots that may have travelled to the brain.

• The treatment for each type of stroke is different, and so correct diagnosis of the

kind of stroke is very important.

• For Ischemic strokes ,the treatment involves methods to restore adequate blood flow

to the brain.

• For Hemorrhagic strokes, the treatment focuses on controlling the bleeding and

reducing the resultant pressure on the brain.

• Strokes can be debilitating both physically and emotionally, and patients will need

therapies such as speech therapy, physical therapy, & occupational therapy.

• Patients can join a support group where they will be given guidance, and can

exchange information, or share experiences with others who have undergone a

stroke.
