By comparing data obtained from the carers of 170 community-resident dementia sufferers with the results of objective cognitive testing, we assessed carer awareness of a range of cognitive deficits in their dependents. Spouses living with demented patients were the best at estimating the overall severity of cognitive impairment, whereas both first-degree (particularly if living with the dementia sufferer) and second-degree relatives were better at identifying and reporting the severity of memory impairment and topographical disorientation. Only one carer was aware of problems with object recognition, although a definite problem was detected in at least 40% of the study group. The testing instruments used (MMSE and CAMCOG) probably under-detected dysnomia and appeared to be inconclusive when compared with carer reports of difficulties that could be attributable to dyspraxia, highlighting the problem of sole reliance on either these instruments or informant accounts to obtain accurate clinical information.
通过将从170名社区痴呆症患者的照料者处获得的数据与客观认知测试结果进行比较，我们评估了照料者对其受照料者一系列认知缺陷的认知情况。与痴呆患者共同生活的配偶最擅长估计认知障碍的总体严重程度，而一级亲属（尤其是与痴呆患者共同生活的）和二级亲属在识别和报告记忆障碍及地形定向障碍的严重程度方面表现更佳。尽管在至少40%的研究组中检测到了明确的物体识别问题，但只有一名照料者意识到了这一问题。所使用的测试工具（简易精神状态检查表和剑桥认知检查表）可能未充分检测到命名障碍，并且与照料者报告的可能归因于失用症的困难相比，结果似乎尚无定论，这凸显了仅依靠这些工具或信息提供者的描述来获取准确临床信息的问题。
