In the last years, there has been a growing interest in the study of cognitive functioning, not only in schizophrenia but also in other psychoses and psychiatric disorders. Attention, memory and information processing deficits may have great relevance as predictors of social adjustment and quality of life.
[corrected] We revised literature concerning comparative studies of neuropsychological performance in schizophrenia and affective disorders, mainly bipolar disorders.
Studies analyzed show contradictory results. Some authors report a more global dysfunction or a more limited and concrete dysfunction in schizophrenia. However, most of the studies, especially those with homogeneous samples of psychotic affective disorders do not find any difference in cognitive functioning between schizophrenic and bipolar patients.
Although some factors as sample selection, clinical state, course of the disorder, make difficult the interpretation of results, it would not exist specific deficits in any of the diagnostic groups studied.
在过去几年中，人们对认知功能的研究兴趣日益浓厚，这不仅体现在精神分裂症患者中，也体现在其他精神病和精神障碍患者身上。注意力、记忆力和信息处理缺陷作为社会适应和生活质量的预测指标可能具有重要意义。
[已修正]我们查阅了有关精神分裂症和情感障碍（主要是双相情感障碍）神经心理学表现比较研究的文献。
分析的研究结果相互矛盾。一些作者报告精神分裂症存在更全面的功能障碍或更局限、具体的功能障碍。然而，大多数研究，尤其是那些对精神病性情感障碍进行同质化样本研究的，并未发现精神分裂症患者和双相情感障碍患者在认知功能上存在差异。
尽管样本选择、临床状态、疾病病程等一些因素使结果的解释变得困难，但在所研究的任何诊断组中都不存在特定的缺陷。
