Delusion of theft and phantom intruder delusion are among the most frequent delusions in dementia. The purpose of this study was to clarify the clinical characteristics of patients with these symptoms. The authors conducted a questionnaire survey; items included age, gender, dementia diagnosis, cognitive function, and activities of daily living. Other clinical characteristics were evaluated using the quality of life questionnaire for dementia. A total of 217 patients with dementia were rated. Frequencies of delusion of theft were as follows: frequent, 7%; sometimes, 11%; rare, 16%; and none, 66%. Frequencies of phantom intruder delusion were as follows: frequent, 4%; sometimes, 10%; rare, 9%; and none, 77%. Comparison between positive and negative groups with these symptoms revealed that positive groups had higher scores in 2 of 6 domains of the quality of life questionnaire for dementia, namely, negative affect and actions, and restlessness. The positive group with delusion of theft had higher scores in cognitive function and activities of daily living than did the negative group. These results suggest that negative affect and action and restlessness might be related to delusion of theft or phantom intruder delusion and that delusion of theft frequently occurs in the early stage of dementia.
盗窃妄想和幽灵闯入者妄想是痴呆症中最常见的妄想类型。本研究的目的是阐明有这些症状患者的临床特征。作者进行了一项问卷调查；调查项目包括年龄、性别、痴呆症诊断、认知功能和日常生活活动。使用痴呆症生活质量问卷对其他临床特征进行评估。总共对217名痴呆症患者进行了评分。盗窃妄想的出现频率如下：频繁出现的占7%；有时出现的占11%；很少出现的占16%；未出现的占66%。幽灵闯入者妄想的出现频率如下：频繁出现的占4%；有时出现的占10%；很少出现的占9%；未出现的占77%。对有这些症状的阳性组和阴性组进行比较发现，阳性组在痴呆症生活质量问卷的6个领域中的2个领域得分较高，即消极情绪与行为以及坐立不安。有盗窃妄想的阳性组在认知功能和日常生活活动方面的得分高于阴性组。这些结果表明，消极情绪与行为以及坐立不安可能与盗窃妄想或幽灵闯入者妄想有关，而且盗窃妄想在痴呆症早期经常出现。
