Posterior circulation stroke syndrome (POCS) refers to the symptoms of a patient who clinically appears to have had a posterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis.

It can cause the following symptoms:

  • Bilateral motor or sensory defect
  • Eye movement problems (e.g.nystagmus)
  • Cerebellar dysfunction
  • Isolated homonymous hemianopia
  • Vertigo

It has also been associated with deafness.[1]
