title: Subjective reports of cognition in relation to assessed cognitive performance following coronary artery bypass surgery.
abstract: Evidence has accumulated to indicate that a proportion of patients who undergo coronary artery bypass surgery (CABS) do develop significant cognitive deficits. This study examines whether those patients who report cognitive deterioration after CABS do show cognitive changes as assessed by neuropsychological testing. The patients who considered that aspects of their cognitive function had deteriorated, were not found to have reduced functions as assessed on appropriate neuropsychological tests. When mood state was examined, it was found that those who report a deterioration in a particular cognitive function, tended to have significantly higher levels of depression as assessed by the Beck Depression Inventory and, to a lesser extent, have higher levels of state anxiety. These findings emphasise that subjective reports of cognitive function following CABS do not reflect actual changes in cognition but rather appear to be sensitive to mood state.
