This study investigated the meanings and etiologies of hallucinations in persons with dementia. Participants were 74 nursing home residents aged ≥ 65 diagnosed with dementia. Most of the reported visual and auditory hallucinations involved talking to persons who are not present, a phenomenon described as either a visual or auditory hallucination, or both. All participants who were reported to experience a hallucination had poor vision. Current results suggest that hallucination was a term staff caregivers used for the phenomena they could not easily explain, demonstrating their lack of understanding of the resident and/or the phenomena they termed hallucination. The classification of hallucinations into subtypes may not be meaningful, and most visual and auditory hallucinations were not associated with negative affect. Some hallucinations occurred out of boredom, which exacerbated the sensory deprivation experienced by these persons, thereby increasing the likelihood of hallucinations.
本研究探讨了痴呆患者幻觉的意义和病因。参与者为 74 名年龄≥65 岁、被诊断患有痴呆症的养老院居民。报告的大多数视觉和听觉幻觉涉及与不在场的人交谈，这种现象被描述为视觉或听觉幻觉，或两者兼有。所有报告有幻觉的参与者视力都很差。目前的结果表明，幻觉是工作人员护理人员用来描述他们难以解释的现象的术语，这表明他们对居民和/或他们称为幻觉的现象缺乏了解。将幻觉分为亚型可能没有意义，而且大多数视觉和听觉幻觉与负面情绪无关。一些幻觉是出于无聊而产生的，这加剧了这些人所经历的感官剥夺，从而增加了出现幻觉的可能性。
