Stroke

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
