Stroke Flashcards
Which area does the anterior cerebral artery supply?
Outer upper surface of the brain:
Frontal lobe
Medial sensory motor cortex
Which area does the middle cerebral artery supply?
Outer lateral surface of the brain:
Sensory motor cortex
Basal ganglia
Broca’s area
Which area does the posterior cerebral artery supply?
The posterior surface of the brain:
Occipital lobe
Temporal lobe
Thalamus
Draw and label the brains arterial supply
See internet
What four arteries supply the brain?
2 vertebral and 2 internal carotid arteries
Which area of the brain does the Basilar artery supply?
Brainstem, cerebellum and nuclei of cranial nerves
State the difference between stroke and TIA
Stroke is the global loss of cerebral function whereas a TIA is where the brain isn’t getting enough blood
State the two types of stroke and the differences between them
Ischaemic is a blood clot in the brain and a haemorragic is a bleed on the brain
State and describe the two types of ischaemic stroke
Embolic is where a blood clot occurs elsewhere in the body and moves to the brain causing a sudden onset of complete stroke
Thrombotic is where a blood clot forms in the brains arteries causing it to either develop overnight or several days
State the four types of haemorragic stroke
Subarachnoid, intracerebral, subdural and extradural
Which haemorragic is caused by severe trauma?
Extradural and subdural
Which haemorragic is caused by micro-aneurysms and associated with hypertension?
Intracerebral
Which haemorragic is caused by rupture of congenital aneurysm, arteriovenous malformation or trauma?
Subarachnoid
State the management techniques of strokes
MRI, CT, blood tests, treat hypertension, surgery, stents
State four motor symptoms
Weakness, asymmetry, loss of balance, loss of normal movement patterns
