Stroke
                     STROKE
What is a stroke?
A stroke occurs when a blood vessel in the brain ruptures and bleeds, or 
when there’s a blockage in the blood supply to the brain. The rupture or 
blockage prevents blood and oxygen from reaching the brain’s tissues.

Types of strokes
Transient ischemic attack (TIA) involves a blood clot that typically 
reverses on its own.
Ischemic stroke involves a blockage caused by either a clot or plaque in 
the artery. The symptoms and complications of ischemic stroke can last 
longer than those of a TIA, or may become permanent.
Hemorrhagic stroke is caused by either a burst or leaking blood vessel 
that seeps into the brain.

Ischemic stroke
During an ischemic stroke, the arteries supplying blood to the brain 
narrow or become blocked. Blood clots or severely reduced blow flow to 
the brain causes these blockages. Pieces of plaque breaking off and 
blocking a blood vessel can also cause them.

Transient ischemic attack (TIA)
A transient ischemic attack, often called a TIA or ministroke, occurs 
when blood flow to the brain is blocked temporarily.

Hemorrhagic stroke
A hemorrhagic stroke happens when an artery in the brain breaks open 
or leaks blood. The blood from that artery creates excess pressure in the 
skull and swells the brain, damaging brain cells and tissues.

Diet
An unbalanced diet can increase the risk of stroke. This type of diet is 
high in:
salt
saturated fats
trans fats
cholesterol

Tobacco use
Using tobacco in any form also raises the risk of stroke, since it can 
damage the blood vessels and heart. Nicotine also raises blood pressure.

How to prevent a stroke
Lifestyle changes can’t prevent all strokes. But many of these changes 
can make a radical difference when it comes to lowering your risk of 
stroke.

Diagnosis of stroke
Your doctor will do certain tests to help confirm a stroke diagnosis. These 
tests can help them determine whether you had a stroke and, if so:
what may have caused it
what part of the brain is affected
whether you have bleeding in the brain
