Bipolar disorder illness is marked by emotional lability and mood disturbance, as well as various neuropsychological deficits, and the neuroanatomical correlates of many of these deficits are beginning to be identified. Numerous studies have implicated specific cortical and sub-cortical abnormalities in areas associated with executive function, memory, motor function, and the processing of emotion. Although a large body of research has been devoted to the investigation of cognitive and emotion-processing deficits in bipolar disorder, relatively few studies have been devoted to the investigation of how these deficits differ among bipolar disorder subtypes. This is surprising in light of known symptomatological and phenomenological differences found among the illness subtypes. Moreover, the nosological status of bipolar disorder is still considered by many to be uncertain. The aim of this study is to address these ongoing issues by investigating and comparing emotion processing and neuropsychological deficits among bipolar I disorder, bipolar II disorder, and healthy control groups to further clarify the nature and extent of differences in impairment among these groups.
