STROKE FLOW

DIAGNOSIS

STROKE

STROKE MIMICS

Eg. Brain tumour, labrynthitis, seizures, sepsis, syncope, dementia, encephalopathy

ISCHAEMIC STROKE

Blood supply carrying oxygen and nutrients to the brain tissue is cut off due to a blood clot in an artery

TRANSIENT ISCHAEMIC ATTACK

A "mini-stroke" due to a temporary blockage in the blood supply to the brain (i.e. due to atherosclerosis) whereby function is restored but increases the risk of a stroke

HAEMORRHAGIC

Rupture in the wall of a blood vessel in the brain, prevents the supply of oxygen and nutrients to brain tissue

EMBOLIC STROKE

When plaque in arteries from other parts of the body (i.e. heart) breaks off and travels, causing a blood clot in small vessels in the brain

THROMBOTIC STROKE

Blood flowing through arteries deposit cholesterol-laden "plaques" that increase in size, creating a narrowing or blockage in the arteries delivering blood to the brain (i.e. at the bifurcation of the common carotid artery)

INTRACEREBRAL HAEMORRHAGE

High blood pressure (hypertension) causes an aneurysm in the brain to expand and burst

SUBARACHNOID HAEMORRHAGE

Ruptured blood vessel in the subarachnoid space due to a burst aneurysm, arteriovenous malformation or trauma
