Types of stroke
- Ischaemic stroke (risk factors: age, AF, diabetes, hypertension, obesity, hypercholesterolaemia, smoking, obesity, family history)
- Total anterior circulation stoke (TACS) 3/3 of – Higher function (speech/apraxia/neglect), Hemianopia, Hemi-loss (motor/sensory)
- Partial anterior circulation stroke (PACS) 2/3 of – Higher function (speech/apraxia/neglect), Hemianopia, Hemi-loss (motor/sensory)
- Lacunar stroke (LACS) 1/3 of – Higher function (speech/apraxia/neglect), Hemianopia, Hemi-loss (motor/sensory)
- Posterior circulation stroke (POCS) – vertebrobasilar arterial system occlusions
- Occipital → isolated contralateral homonymous visual field defect
- Cerebellar → ipsilateral cerebellar signs
- Brainstem → ipsilateral cranial nerve palsies, bilateral sensory/motor deficit, disorder of eye movements
- Intracerebral haemorrhage (risk factors: age, anticoagulation, alcohol, hypertension, stress, smoking)
Possible clinical features by vascular territory

NB: carotid artery dissection is a cause of anterior circulation stroke and vertebral artery dissection is a cause of posterior circulation stroke. Think about dissection if there is neck pain, the patient is young or there is associated trauma.
