What is a stroke?

A stroke is also known as a brain attack. 

Identifying strokes and treatment

A stroke may be hemorrhagic (caused by bleeding) or
ischemic (embolic) caused by a clot or plaque in a blood
vessel. 

Bleeding ( hemorrhagic) into the brain may be caused
by trauma or rupture of a blood vessel due to high
blood pressure. ICP monitoring may be necessary for 
the patient with a hemorrhagic stroke.

In the case of an embolic stroke, a blood clot may
obstruct the flow of blood in the brain. This will also
affect oxygen to the brain.

Embolic strokes are usually treated with drugs such
as TPA ( Tissue Plasminogenic Activator). Antihypertensive
drugs and anti- seizure medications may also be ordered.

TPA ( Thrombolytic Plasminogen Activator)
is not only used for reperfusion in patients
who had a myocardial infarction, it is also
used in the treatment of embolic strokes.

Can a stroke be prevented?

It is suggested that a stroke can be prevented. People who
smoke frequently, eat a diet rich in cholesterol foods and
do not exercise regularly, are considered to be at risk.

High blood pressure and obesity also puts someone at risk.
Lifestyle changes such as regular exercise, eating a diet with

fresh fruits and vegetables, as well as high fiber may help to

reduce stroke risk.

While on stage, she suddenly starts having
trouble getting her words out. Her right arm
also feels weak. These symptoms are classic
of stroke symptoms.

Severe headache, mental confusion, visual
disturbances and right or left sided weakness
may also occur.
