A
Acute Stroke
- Caused by an intra-cerebral haemorrhage or infarct
- 80 – 85% are ischaemic
- 15 – 20% are haemorrhage, which about 50% die
- Main risk factors are atrial fibrillation, hypertension, smoking, aging and diabetes
- It is the leading cause of disability
- Second leading cause of dementia
- Third leading cause of death
- CT scan or MRI to differentiate if the stroke is ischaemic or haemorrhagic in nature

Q
Acute Stroke
- Ischaemic stroke, is compromised vascular supply to the brain which activates the isachemic cascade. This causes a local _____ of oxygen and glucose. This leads to the failure of energy production via the ATP pathways and ass a results leads to cell _____ and then _____.
- Haemorrhagic strokes, is a _____ of a blood vessel in the brain. This causes _____ due to the decreased vascular supply and increases the intra-cranial pressure due to the bleeding.
A
Acute Stroke
- Ischaemic stroke, is compromised vascular supply to the brain which activates the isachemic cascade. This causes a local depletion of oxygen and glucose. This leads to the failure of energy production via the ATP pathways and ass a results leads to cell injury and then necrosis.
- Haemorrhagic strokes, is a rupture of a blood vessel in the brain. This causes hypoxia due to the decreased vascular supply and increases the intra-cranial pressure due to the bleeding.

- Confusion
- Vision
- _____ and dizziness
- _____ within 24 hours of symptoms and MRI

- _____ at top of basilar artery or middle cerebral artery stem
A
Transient Ischaemic Attack
- Internal carotid artery stenosis due to atherothrombotic lesions
- Lesions of distal vertebral artery, vertebrobasilar junction and proximal basilar artery
