长期住院对精神分裂症患者认知功能的影响

目的：探讨长期住院对精神分裂症患者认知功能的影响。方法：对56例长期住院（≥5年）与49例住院时间较短（≤1年）的精神分裂症患者的精神症状和认知功能进行比较，采用阳性与阴性症状量表（PANSS）、韦氏成人智力量表（WAIS-R）、威斯康星卡片分类试验（WCST）等评定患者的认知功能。结果：长期住院（≥5年）组在智商、注意、记忆，以及信息整合与执行功能等均显著较差。结论：长期住院对精神分裂症患者认知功能有负面影响。

Effects of chronic hospitalization on cognitive function in patients with schizophrenia

Objective： To probe the effects of chronic hospitalization on cognitive function in schizophrenic patients. Method. Psychotic symptoms and cognitive functions were compared between patients in chronic hospitalization group （more than 5 years, n = 56） and in short-term hospitalization group （less than one year, n = 49）. Positive and negative syndrome scale （PANSS） was used to evaluated the psychotic symptoms, and Wechsler adult intelligence scale （WAIS） and Wisconsion card sorting test （WCST） were used to evaluate the cognitive functions. Results： Patients in chronic hospitalization （≥5 year） group had significant poorer performances in the areas such as intelligence quotient, attention, memory and functions of information integration and execution. Conclusion：Chronic hospitalization has negative influence on cognitive function in patients with schizophrenia.
