Basic Stroke

Stroke

Stroke is when your brain does not receive the adequate amount of blood supply which would lead brain tissue damage. .maybe due to loss of blood (after injury) or not enough blood.

Causes

Stroke can be caused by ruptured vessels of the brain due to hemorrhage (in this case it is called hemorrhagic stroke) and it can also caused by not having enough blood supply due to the blockage of the brain vessels (aka cerebral vessels), blockage maybe due to "fatty balls" stuck within the wall of the vessel, maybe due to diseases like artherosclerosis (later will be explained further). In this case the stroke is called ischemic stroke.blockage vessels restricts the flow of blood, oxygen, and nutrients to the brain.

So 2 types of stroke. hemorrhagic and ischemic!!

hemorrhage=blood loss caused by bleeding within the brain or surrounding tissues

ischemic= not enough blood caused by a blockage in a blood vessel


How to get stroke =) [ Risk Factors]

risk factors differ for both types.

for hemorrhagic stroke, the risk factors are smoking, high blood pressure, illegal drug use

for ischemic stroke, the risk factors are age (greater than 40 have higher risk!), heart diseases, high blood pressure, diabetes, obesity and more (you can always search you know =p )


Treatment

doctors must find out which stroke you have because the treatment is different for each type of stroke =)

hemorrhagic stroke:

doctors will first determining the cause of the bleeding, later blood pressure will be controlled. dr will ask the patient to stop any medications that can increase bleeding (such as aspirin and warfarin). the main principle is to stop bleeding!

ischemic stroke:

the aim is to restore blood flow!!we need blood to the brain as quickly ASAP! Doctors uses drugs such as thrombolytics to lyse (to destroy/to liquidize) the thrombus (which is like a blood clot,like small balls of blood clot). so after the thrombus is lysed, the passage of the vessels will be cleared, so blood can flow back to normal!!

doctors will also uses aspirin (anticoagulant) to liquidify the blood clots. gasppppp!!

remember aspirin??using it could treat and could also kill!!that is why it is important to know the type of stroke the patient has!!!
