简要总结
This project will explore the feasibility and efficacy of the fully immersive virtual reality leisure cognitive training tool developed by Chang Gung University in patients with mild to moderate dementia. The feasibility study will assess the feasibility and emotion-related indicators of 10 patients before and after a single training session. The efficacy study is planned to adopt a crossover randomized controlled trial, recruiting 30 patients for 15 sessions, each lasting 65 minutes, conducted three times a week. The assessment will include tests on the primary variable of cognitive function and secondary variables such as activities of daily living, quality of life, emotion, clinical symptoms, etc.

入选标准
- •Age over 55 years;
- •Diagnosed with mild or moderate dementia (primarily degenerative dementia) by a consulting physician or based on past medical records;
- •A score of at least 11 but no more than 23 on the Mini-Mental State Examination (MMSE);
- •Has at least one family member or a regularly contacted friend (with the person's mobile number and contact at least once a week);

研究组 & 干预措施
VR training therapy
Guide the patient through a 5-minute warm-up, which mainly involves explaining, familiarizing with, or reviewing VR operations. After the warm-up, proceed with the first part of the VR gardening training for 10 minutes, followed by 5 minutes of eye and stretching exercises. Then, continue with the second part of the VR gardening training for another 10 minutes, followed by 5 minutes of eye massage and stretching exercises. This sequence is repeated for a total of four cycles.

结局指标
主要结局
Change scores of Montreal Cognitive Assessment
时间窗: Before the intervention arms within a week, within a week after the waiting period ends, and within a week after the last treatment .
The Montreal Cognitive Assessment (MoCA) will be used to assess general cognitive functions. It examines several cognitive domains with a total score of 30 and higher values indicate better cognitive functions. The MoCA has been shown to be a valid and promising tool to evaluate the global cognitive function in patients with stroke. Minimum: 0 (worst performance) Maximum: 30 (best performance) The psychometric properties of MoCA are good to excellent for patients with cerebrovascular diseases.
Change scores of Stroop test
时间窗: Before the intervention arms within a week, within a week after the waiting period ends, and within a week after the last treatment .
The participants will be tested under congruent and incongruent conditions. In the congruent condition, the participant will name the color ink of a word which is consistent with the written color name; whereas in the incongruent condition the participant will name the color ink differs from the written color name. The time to complete the task will be calculated for each condition.Minimum: 0 , Maximum: but typically no upper limit. Higher scores indicate worse performance (greater cognitive interference and slower response time).
Change scores of Color trials test
时间窗: Before the intervention arms within a week, within a week after the waiting period ends, and within a week after the last treatment .
For Part 1, the respondent uses a pencil to rapidly connect circles numbered 1-25 in sequence. For Part 2, the respondent rapidly connects numbered circles in sequence, but alternates between pink and yellow. The length of time to complete each trial is recorded, along with qualitative features of performance indicative of brain dysfunction, such as near-misses, prompts, number sequence errors, and color sequence errors.Minimum: Greater than 1 second (best performance) Maximum: No upper limit .Higher scores indicate worse performance (longer completion time and greater cognitive impairment).
Change scores of Frontal Assessment Battery
时间窗: Before the intervention arms within a week, within a week after the waiting period ends, and within a week after the last treatment .
This study utilizes this scale to assess various aspects of frontal lobe function, including executive function, behavioral regulation, and planning. The test consists of six subtests: Similarities, Verbal Fluency, Motor Sequencing, Conflicting Instructions, Go-No-Go, and Comprehending Behavior. Each subtest is scored from 0 to 3, with a total possible score of 18 points. The Taiwanese version of the frontal assessment scale has demonstrated good reliability and validity, showing consistency with tconsistency with the original version and strong construct validity. Minimum: 0 (worst performance) Maximum: 18 (best performance) Higher scores indicate better frontal lobe function, while lower scores suggest greater impairment.
