1. What is Stroke?
Stroke is brain attack
A Stroke, also known as CEREBROVASCULAR ACCIDENT (CVA), CEREBROVASCULAR INSULT (CVI), or Brain Attack. It can happen to anyone at any time. It occurs when blood flow to an area of brain is cut off or when poor blood flow to the brain results in cell death.. When this happens, brain cells are deprived of oxygen and begin to die. When brain cells die during a stroke, abilities controlled by that area of the brain such as memory and muscle control are lost.
2. What are the types of stroke ?
There are 3 varieties of arterial stroke –
ischemic stroke , hemorrhagic stroke (brain hemorrhage) and subarachnoid hemorrhage.
3. What is ischemic stroke?
Ischemic stroke also called “clot type stroke” occurs when the blood supply to part of the brain is suddenly interrupted due to a clot in the blood vessel
4. What is hemorrhagic stroke?
Hemorrhagic stroke occurs when a blood vessel in the brain bursts, spilling blood into the brain
5. What is subarachnoid hemorrhage?
Subarachnoid hemorrhage occurs when a blood vessel in the brain bursts, spilling blood in the spaces around the brain
6. What are the symptoms of stroke?
The symptoms of stroke are
· Sudden numbness or weakness, especially on one side of the body;
· Sudden confusion;
· Trouble speaking or understanding speech;
· Sudden trouble seeing in one or both eyes;
· Sudden trouble with walking, dizziness, or loss of balance or coordination; or
· Sudden severe headache with no known cause.
Is there any treatment?
Generally there are three treatment stages for stroke
(1) Therapy immediately after the stroke
(2) Post-stroke rehabilitation
What is acute stroke therapy ?
Acute stroke therapies try to stop a stroke while it is happening by quickly dissolving the blood clot causing an ischemic stroke or by stopping the bleeding of a hemorrhagic stroke.
What is the first aid for stroke ?
You need to go to the closest hospital as early as possible. The patient should not be given anything orally including water.
What will be done in the hospital ?
Your doctor is going to get an emergency CT scan of the brain and will treat you with a clot busting medicine (tPA) in case of ischemic stroke, depending on scan findings and a few other clinical factors. This medication can be given only if you reach the doctor within 4.5 hours of stroke onset. In specialized centres, the same medication can be given directly into the clot after performing an angiogram, upto 6 hours of stroke onset.
What happens if you reach the hospital more than 6 hours after stroke onset ?
There are still medications which can be given, but the clot busting medication can not be given.
How do we prevent stroke ?
How to prevent recurrent stroke ?
Taking medications prescribed by your doctor without fail and following a healthy lifestyle.
