This study followed 141 people after stroke and compared the usefulness of different methods for diagnosing delirium. The results show delirium is a common occurrence after stroke and usually presents within the first 72 hours after stroke. Although a smaller-scale study than was originally hoped, the results highlighted the importance of frequent screening for delirium. The results of the study also show the difficulties of detecting delirium, in part caused by the confounding effects of the potential focal neurological deficits of stroke.1

Lacunar infarctions are small subcortical infarcts, <1.5 cm in diameter, within deep areas of the brain. Roughly 1 in 5 strokes are estimated to be lacunar strokes.
The cerebellum is supplied with blood via three branches of the basilar artery – the posterior inferior cerebellar artery (PICA), the anterior inferior cerebellar artery (AICA), and the superior cerebellar artery (SCA).
The image shows how the blood supply of the brain is arranged. The internal carotid arteries branch to form two major cerebral arteries on each side. The posterior circulation to the brain is mediated by the vertebral arteries.
