1

What are types of ischaemic stroke

Embolus from anywhere
Thrombosis- clot forms locally from within artery
Systemic hypoperfusion- secondary to systemic hypotension
Cerebral venous sinus thrombosis- clot in vein results in venous congestion and hypoxia

2

Classification of haemorrhagic stroke

Intracerebral haemorrhage after bleeding in parenchyma or intra ventricular
Outside of pia mater so subarachnoid or epidural

3

Subarachnoid bleed

Between pia mater and subarachnoid layer- arterial

4

What does anterior cerebral artery supply

Anteromedial area of cerebrum

5

What does middle cerebral artery supply

Most of lateral cerebrum

6

What does posterior cerebral artery supply

Medial and lateral posterior cerebrum- includes cerebellum and brain stem

7

Bamford stroke classifications

Total anterior circulation stroke
Partial anterior circulation stroke
Posterior circulation syndrome
Lacunar stroke

11

What do you need for diagnosis of POCS

Cranial nerve palsy with with contra lateral motor or sensory defect
Bilateral motor or sensory defect
Cerebrellar dysfunction
Conjugate eye movement disorder
Isolated homonymous hemianopia

12

What is a conjugate eye movement disorder

Ability to move both eyes in unison

13

15

What are examples of cerebrellar dysfunction

Vertigo
Nystagmus
Ataxia- like being drunk so slurring stumbling and poor coordination

16

What is a lacunar stroke

Subcortical stroke where there is no loss of higher cerebral function

17

What do you need for a lacunar stroke

Pure sensory stroke
Pure motor stroke
Senori motor stroke
Ataxic hemiparesis

18
