Older adults with questionable dementia are at risk of progressing to dementia, and early intervention is considered important. The present study investigated the effectiveness of a virtual reality (VR)-based memory training for older adults with questionable dementia.
A pre-test and post-test design was adopted. Twenty and 24 older adults with questionable dementia were randomly assigned to a VR-based and a therapist-led memory training group, respectively. Primary outcome measures included the Multifactorial Memory Questionnaire and Fuld Object Memory Evaluation.
Both groups demonstrated positive training effects, with the VR group showing greater improvement in objective memory performance and the non-VR group showing better subjective memory subtest results in the Multifactorial Memory Questionnaire.
The use of VR seems to be acceptable for older adults with questionable dementia. Further study on the effect of educational background and memory training modality (visual, auditory) is warranted.
有可疑痴呆症的老年人有发展为痴呆症的风险，早期干预被认为很重要。本研究调查了基于虚拟现实 (VR) 的记忆训练对有可疑痴呆症的老年人的有效性。
采用预测试和后测试设计。20 名和 24 名有可疑痴呆症的老年人被随机分配到基于 VR 的记忆训练组和治疗师主导的记忆训练组。主要结果测量包括多因素记忆问卷和富尔德物体记忆评估。
两组均表现出积极的训练效果，VR 组在客观记忆表现方面的改善更为明显，而非 VR 组在多因素记忆问卷的主观记忆子测试中表现更好。
对于有可疑痴呆症的老年人来说，使用 VR 似乎是可以接受的。需要进一步研究教育背景和记忆训练模式（视觉、听觉）的效果。
