The prevalence and quality of depression (Geriatric Depression scale), were studied in groups of cognitively impaired patients referred for neuropsychological assessment from a short-term assessment ward (Group A), and from long-term care wards (Group B). Cognitively intact assessment ward patients served as a comparison group (Group C) to control for effects of hospitalization on mood. The prevalence of depression did not differ for the cognitively impaired short-term assessment and long-term care groups. However, cognitively impaired patients in Group A had a higher prevalence of depression than cognitively intact patients in Group C. GDS scores did not correlate with measures of severity of cognitive impairment or of self-care disability in Groups A and B, although elevated GDS scores were significantly correlated with higher Verbal IQ scores in these groups. Analysis of individual GDS items responses suggested that depression in cognitively impaired elderly tends to be characteristic of adjustment disorder rather than Major Depression.
在从短期评估病房（A组）和长期护理病房（转介进行神经心理学评估的认知受损患者组（B组）中，研究了抑郁症的患病率和严重程度（采用老年抑郁量表）。认知功能正常的评估病房患者作为对照组（C组），以控制住院对情绪的影响。认知受损的短期评估组和长期护理组的抑郁症患病率没有差异。然而，A组中认知受损患者的抑郁症患病率高于C组中认知功能正常的患者。A组和B组的老年抑郁量表得分与认知障碍严重程度或自理能力障碍指标不相关，尽管这些组中升高的老年抑郁量表得分与较高的言语智商得分显著相关。对老年抑郁量表各单项反应的分析表明，认知受损老年人的抑郁症往往具有适应障碍的特征，而非重度抑郁症。
