Abstract
Neurocognitive dysfunction is increasingly recognized as a prominent feature of bipolar disorder. Cognitive function seems to be impaired across different states of bipolar illness. Nervertheless, research that studies neuropsychological functioning in acute phases is scarce. Acutely ill patients have shown dysfunctions in several cognitive areas. We reviewed the literature on neuropsychological studies of acute phases to highlight neurocognitive deficits in mixed and pure mania. The results show dysfunctions in sustained attention that are significantly more important in mixed mania rather than in pure mania. Impulsive pattern of responding seems to characterize pure manic state. We also found impairments in processing speed, verbal and spatial learning/memory and executive functions, including cognitive flexibility, inhibitory control, conceptual reasoning, planning and problem solving. Disturbance in executive functioning seems to be more important in pure mania rather than mixed mania.
