Background And Objective: There is increasing evidence that survivors of ARDS may have impairments in cognitive function, mood and quality of life. This study investigated associations between cognitive impairment, mood disorders and quality of life in a select group of ARDS survivors.
Methods: A cross-sectional study was conducted to describe the specific impairments in cognitive function, mood and quality of life in a group of 79 self-selected ARDS survivors who contacted an Internet-based support site.
Purpose: Describe initial development and validation of a test battery composed of established instruments designed to detect, via telephone interview, cognitive abnormalities in survivors of acute respiratory distress syndrome.
Methods: Two cross-sectional studies were performed, including the following phases: (1) initial battery construction, (2) feasibility, (3) item reduction, (4) convergent and divergent validity, and (5) telephone administration compared with in-face interviews in a separate population.
Results: There was a broad range of cognitive function detected in the derivation population, and all subjects completed the interview.
Background: Diffuse axonal injury (DAI) is one of the most common and important pathologic features of traumatic brain injury (TBI). The susceptibility of axons to mechanical injury appears to be due to both their viscoelastic properties and their high organization in white matter tracts. Although axons are supple under normal conditions, they become brittle when exposed to rapid deformations associated with brain trauma.
