小组数字游戏：认知障碍活动中老年痴呆症患者的生活体验 (PLwD)

实验性的：基于小组的数字游戏

行为的：基于小组的数字游戏

互动数字游戏活动通过Obie技术实现。 多种游戏被投影到桌面，参与者通过用手“触摸”图像与游戏互动。 该系统包含检测手部运动的传感器，使活动完全互动。 提供超过200种游戏。 一些热门游戏的例子包括麻将（参与者通过触摸匹配相同的牌）和环游世界（参与者根据国旗识别正确的物品，例如为英国选择伦敦双层巴士）。 对于许多游戏，难度级别可调，这对于涉及数学的游戏尤其有用。 游戏根据参与者的请求以及协助者的推荐进行选择。

Montreal Cognitive Assessment (MoCA):

Montreal Cognitive Assessment contains 30 items and takes approximately 10 minutes to administer assessing multiple cognitive domains such as short-term memory, visuospatial abilities, and abstraction. The minimum total score is 0 and the maximum tota score is 30. The higher scores are associated with better cognitive function, and a score of 26 and higher is considered normal.

Neuropsychiatric Inventory Questionnaire (NPI-Q)

Neuropsychiatric Inventory Questionnaire is an informant-based instrument that assesses the possible presence of 12 neuropsychiatric symptoms in dementia, including delusions, hallucinations, agitation/aggression, dysphoria/depression, anxiety, euphoria/elation, apathy/indifference, disinhibition, irritability/lability, aberrant motor behaviors, night-time behavioral disturbances and appetite/eating disturbances. It asks the presence each symptom and its severity with a 3-point scale. The minimum total score is 0, and the maximum total score is 36. Higher scores indicate more severe neuropsychiatric symptoms and/or greater caregiver distress. It is shown to be a reliable and valid instrument. Most informants will be able to complete this instrument in less than five minutes.
