Be aware of the risk factors for stroke.

Answer 1

age, hypertension, cardiac disease, diabetes, smoking, cholesterol, bleeding disorders

Question 2

• Describe the acute treatments for stroke.

Answer 2

restore blood supply, prevent extension of ischaemic damage, protect vulnerable brain tissue, avoid repurfusion injury and be non-toxic

Question 3

• Understand the primary and secondary prevention of stroke.

Question 4

Outline the investigation of stroke.

Answer 4

CT scan, MRI scan, perfusion CT or CT angiogram

Question 5

what is a stroke

Answer 5

a blocked or ruptured blood vessel in the brain causing a failure of neuronal function leading to a deficit in brain function

Question 6

causes of stroke

Answer 6

Blockage with thrombus or clot
Disease of vessel wall
Disturbance of normal properties of blood (leukaemia)
Rupture of vessel wall
(haemorrhage)
Infarctions>haemorrhage

Question 7

hemorrhagic stroke

Answer 7

blood leaks into brain fluid

Question 8

ischemic stroke

Answer 8

clot stops brain supply to an area of the brain

Question 9

large artery disease

Answer 9

bifurcation of carotid blood vessels and tends to be in areas of shear force and lots of turbulence then a clot forms and ends up in the blood vessel in brain

Question 10

cardioembolic stroke

Answer 10

clot forming in left atrial appendage and travels t aorta and causes a occlusion of vessel and leads to dead tissue

Question 11

lacunar stroke

Answer 11

Large vessel have small branches going into brain tissue and only effects small area of brain associated with hypertension

Question 12

symptoms and signs of a stroke

Answer 12

motor, sensor, speech, vision, gaze palsy (can’t move both eyes together)

Question 13

stroke subtypes

Answer 13

TACS- total anterior circulation stroke- whole middle cerebral artery
PACS- partial anterior circulation stroke- middle cerebral artyer
LACS- lacunar stroke in small arteries
POCS- posterior circulation stroke- posterior blood vessels
