Delirium, Electroencephalographic Alterations and Cortical Spreading Depression (CSD) in Critical Illness

Delirium in the intensive care unit is an acutely developed brain dysfunction affecting up to 80 % of patients. It is associated with significantly increased morbidity and mortality during admission and post-discharge. The mechanism behind the condition is poorly understood but assumably multifactorial, and the purpose of this study is to investigate the pathophysiology further.
