简要总结
Both visual impairment and dementia are prevalent in the elderly population. Cognitive stimulation therapy (CST) is an evidence-based intervention for people with mild-to-moderate dementia. Virtual reality (VR) has been used in cognitive rehabilitation. However, the efficacy of CST and the feasibility of incorporating VR into therapy targeting people with dementia and visual impairment (PwDVI) have rarely been explored. The current pilot study addressed two issues: 1) To study the efficacy of conventional CST on PwDVI in different cognitive domains and 2) To explore the feasibility and efficacy of VR-CST on PwDVI in various cognitive domains.

研究组 & 干预措施
Conventional CST group
A total 14 sessions of conventional cognitive stimulation therapy (CST) with different themes were delivered twice a week to patients with dementia in groups of four to five. Therapy materials included real objects, pictures and videos presented via iPADs where users can enlarge the images manually or under facilitator's assistancd.
干预措施: Conventional Cognitive Stimulation Therapy (Conventional CST) (Behavioral)
VR-CST
A total of 14 sessions of virtual reality cognitive stimulation therapy (VR-CST) with different themes were delivered twice a week to patients with dementia in groups of four to five. In the VR-CST condition, participants wore a head-mounted display (HMD; model: DPVR P1 Pro Headset) for the themed activities in every session except sessions 1 and 14. In these two sessions, group physical activities (such as passing a ball from one participant to another) were conducted, so no HMDs were used. In other sessions, panoramic images (e.g., wet market) and videos (e.g., the neighborhood surroundings) prepared by the project team were mainly used, supplemented by 2-dimensional images /videos in which preparing panoramic images/videos was deemed impossible.
