Neuro- Cerebral Vasculature+cerebrovascular Disorder

Question 1

4 types of haemorrhage

Answer 1

extradural
subdural
subarachnoid
intracerebral

Question 2

cause of subarachnoid and
intracerebral

Answer 2

subarachnoid- ruptured aneurysm

intracerebral- spontaneous hypertensive

Question 3

define stroke (cerebrovascular accident) and most common cause

Answer 3

rapidly developing focal disturbance of brain function of presumed vascular origin and of >24 hours duration

Thrombo-embolic (85%) or haemorrhage (15%)

Question 4

define transient ischaemic attack

Answer 4

rapidly developing focal disturbance of brain function of presumed vascular origin that resolves completely within 24 hours”

Question 5

ischaemia vs infarction

Answer 5

ischemia =blood flow to a tissue has decreased- permanent damage if not restored quick enough

infarction= blood flow completely cut off =necrosis, or cellular death.

Question 6

risk factor for stroke

Answer 6

CHADS
cardiac disease
hypertension
age
DM
smoking

Question 7

symptoms of anterior cerebral artery

Answer 7

Paralysis of contralateral structures (leg > arm, face)

Disturbance of intellect, executive function and judgement (abulia)

Loss of appropriate social behaviour

Question 8

Middle cerebral artery symptoms

Answer 8

“Classic stroke”

Contralateral hemiplegia: arm > leg

Contralateral hemisensory deficits

Hemianopia

Aphasia (L sided lesion)

Question 9

Posterior cerebral artery symptoms

Answer 9

Visual deficits

homonymous hemianopia

visual agnosia
