Abstract

Introduction: We investigated the degree of cognitive insight in patients with Alzheimer's Disease (AD) regarding their hallucinations, aiming to elucidate the subjective experiences and perceptions associated with this phenomenon.

Methods: Using a cross-sectional design, we invited both AD patients (n = 31) and their informants to evaluate the occurrence of hallucinations. Degree of cognitive insight was based upon the discrepancy between the patients' and informants' evaluations.

Results: Analysis demonstrated that AD patients rated the occurrence of hallucinations lower than their informants, indicating that patients tended to underestimate the frequency of their hallucinations. The discrepancy between the ratings of patients and informants was negatively correlated with cognitive functioning, suggesting that a greater discrepancy (indicating poorer insight) was associated with lower cognitive functioning in patients.

Discussion: Our findings highlight the deficits in insight into hallucinations among AD patients, specifically indicating that AD patients have limited awareness of their own hallucinations. Furthermore, our findings support the idea that deficits in insight into hallucinations are associated with the progression of AD.

阿尔茨海默病患者对幻觉的认识有限。

简介我们调查了阿尔茨海默病患者（AD）对其幻觉的认知洞察程度，旨在阐明与这一现象相关的主观体验和感知：我们采用横断面设计，邀请阿尔茨海默病患者（31 人）及其知情者对幻觉的发生进行评估。结果：分析表明，AD 患者对幻觉的评价为 "无幻觉"，而对 "有幻觉 "的评价为 "有幻觉"：分析表明，AD 患者对幻觉发生率的评价低于其告知者，这表明患者倾向于低估幻觉发生的频率。患者和信息提供者评价之间的差异与认知功能呈负相关，表明差异越大（表明洞察力越差），患者的认知功能越低：我们的研究结果突显了AD患者在洞察幻觉方面的缺陷，尤其表明AD患者对自身幻觉的认知有限。此外，我们的研究结果还支持这样一种观点，即对幻觉的洞察力缺陷与AD的进展有关。

期刊介绍： Cognitive Neuropsychiatry (CNP) publishes high quality empirical and theoretical papers in the multi-disciplinary field of cognitive neuropsychiatry. Specifically the journal promotes the study of cognitive processes underlying psychological and behavioural abnormalities, including psychotic symptoms, with and without organic brain disease. Since 1996, CNP has published original papers, short reports, case studies and theoretical and empirical reviews in fields of clinical and cognitive neuropsychiatry, which have a bearing on the understanding of normal cognitive processes. Relevant research from cognitive neuroscience, cognitive neuropsychology and clinical populations will also be considered.
