Types of stroke
Broadly, a stroke can be divided into ischaemic stroke or intracerebral haemorrhage. Types of ischaemic stroke include:
- 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
