Early intervention is considered important in older adults with questionable dementia who are at risk of progressing to dementia. The authors hypothesised that a memory training programme using virtual reality would lessen cognitive decline by providing cognitive support in the encoding and retrieval processes of memory. Community dwelling cognitively impaired older adults were recruited by convenience sampling from community and self-help groups. Participants were randomly assigned to a VR-based (n=20) and a therapist-led memory training group (n=24). A pre-test and post-test design was used. 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 authors conclude that the use of VR seems to be acceptable for older adults with questionable dementia. The suggest further study is needed to assess the effect of educational background and memory training modality (visual, auditory).
