several studies have assessed delirium post-stroke but conflicting results have been obtained. Also, the natural history and outcome of delirium post-stroke need to be fully elucidated. ⋯ delirium is common post-stroke. Most cases develop at stroke onset and remain delirious for an appreciable period. Delirium onset is associated with stroke severity (low admission Barthel), unsafe swallow on admission, poor vision pre-stroke and a raised admission CRP. Delirium is a marker of poor prognosis.
