Subjective complaints versus neuropsychological test performance after cardiopulmonary bypass.
The study by Newman et al. (Journal of Psychosomatic Research, 1989) compared subjective reports of cognition with assessed cognitive performance in patients one year after coronary artery bypass surgery. The current study reinvestigated this relation in a larger and more heterogeneous group--90 cardiac patients six months after cardiopulmonary bypass--using a more extensive checklist of subjective complaints and different neuropsychological tests. In agreement with previous research, the patients who reported complaints in specific cognitive areas were not found to have impaired cognitive functions as assessed with appropriate neuropsychological tests. The patients who reported deterioration in cognition after surgery were found to have higher levels of depression and state anxiety. These differences were significant for almost all evaluated cognitive functions. An alternative explanation of the relationship between mood and cognitive complaints based on personality traits, i.e., neuroticism, is offered.
