It is widely accepted that patients with schizophrenia have some degree of cognitive deficiency and that cognitive deficits are an inherent part of the disorder. Historically, there has been less focus on cognitive deficits in patients with bipolar disorder; however, numerous studies of cognition in patients with bipolar disorder, including several comprehensive meta-analyses of bipolar patients who were euthymic at the time of testing, have recently been undertaken.1-4 Each of these analyses found that cognitive impairment persists during periods of remission, mainly in domains that include attention and processing speed, memory, and executive functioning.4
