Critical illness acquired brain injury: Neuroimaging and implications for rehabilitation.

Objective: The increasing likelihood of surviving critical illness has resulted in a large and growing number of individuals transitioning from medical and surgical intensive care units (ICUs) to their homes. Many ICU survivors develop pervasive morbidities in physical, psychological, and cognitive functioning that adversely impact day-to-day functioning, ability to return to work, and quality-of-life. These individuals have been extensively studied with neuropsychological test batteries, but relatively little research has been conducted using neuroimaging.
