A unique emotional processing profile of euthymic bipolar disorder? A critical review

ObjectivesTo undertake a critical review of the literature on emotional processing (EP) in bipolar patients in remission. This literature review focuses on a number of dimensions of EP including facial emotion recognition, emotional memory, affective theory of mind (ToM), affective attention and affective auditory information processing.MethodsA systematic search was conducted through PsychINFO and Medline databases to obtain relevant literature. Studies that include behavioural measures of EP were included.ResultsThe findings from this review demonstrate that bipolar disorder (BD) patients continue to exhibit some EP deficits during euthymic phases. A number of factors believed to contribute to such findings have been highlighted.ConclusionsThis review has shed light on some of the conflicting findings reported in the literature and thus offers a more comprehensive profile of euthymic bipolar patients' EP abilities. This information could enrich clinicians' therapeutic efforts to minimise relapse by attending to euthymic bipolar patients' specific emotional processing difficulties.
