Oxford classification of strokes

TACS -

• All 3 of: Unilateral hemiparesis, homonymous Hemianopia, higher cortical dysfunction (speach or visuospatial)
• Large strokes, MCA/ICA thrombus/embolus

PACS -

• 2 of: Unilateral hemiparesis, homonymous Hemianopia, higher cortical dysfunction (speach or visuospatial)
• Tend to have a stroke affecting a branch of the MCA thrombus/embolus

POCS -

• 1 of:
  • Bilateral motor or sensory deficit
  • Cerebellar/brainstem signs
  • Isolated homonymous hemianopia
  • conjugate eye movement disorder
  • Cranial nerve palsy & contralateral motor/sensory deficit
• Vertebrobasillar arteries: Brain stem, thalamus, cerebellum, occipital lobes

LACS -

• 1. ataxic hemiparesis 2) pure motor 3) pure sensory 4) sensorimotor 5) dysarthria + clumsy hand
• Due to occlusion of small vessels, end arteries so area being supplied dies
  • Basal ganglia, thalamus, internal capsule, brain stem

Posterior stroke syndromes

• Basilar artery occlusion
• Anterior inferior cerebellar artery occlusion
• Wallenberg’s syndrome (lateral medullary syndrome)
  • DANVAH
  • dysphagia
  • ipsilateral ataxia
  • ipsilateral nystagmus
  • vertigo
  • anasthesia
  • ipsilateral horners syndrome
• Weber’s syndrome (medial midbrain syndrome) - (paramedian branches of the upper basilar and proximal posterior cerebral arteries)
