Alzheimer Disease, Cognitive Impairment
Conditions
Brief summary
The Cogstate Brief Battery (CBB) is a computerized measure for cognitive screening that consists of four cognitive tasks to assess psychomotor function, attention, learning, and working memory, and provides an easy-to-interpret report without the need for manual scoring. Clinical trials and research studies have proven the validity of CBB for cognitive assessment and distinguish MCI or dementia from normal aging. Participants express a growing acceptance of the use of computerized tests for detecting cognitive impairment, viewing it as a potential tool to improve quality of patient care and the patient-clinician relationship when used in conjunction with the human touch. The CBB utilizes non-verbal playing-card stimuli in order to minimize language, educational and cultural biases affecting performance. It has the advantages of being portable (adaptable to notebooks, tablets, and even smart phones), short (20-30 min), game-like in presentation and thus motivating, and cross-culturally adaptable. The CBB is well liked in waiting rooms of primary care settings. It is assumed that the CBB will also be highly accepted by Taiwanese.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| CBB Testing Score and Brain Age Score | Data analysis and study report: 3 months | Participant satisfaction with using CBB will be measured by the paper-and-pencil satisfaction survey including 15 questions. See Appendix 1: Satisfaction Survey for Participant. Score of Question 2 will be ranged from Strongly agree (1) to Strongly disagree (5). Scores of Question 3\ 13 will be ranged from Strongly disagree (1) to Strongly agree (5). The participant satisfaction rates will be estimated from Question 2, 3, 5, 6, 8, 9, 11, 12 and 13, and calculated in accordance with the following formula: Satisfaction rate = (number of score 5 and 4 / number of answers) x 100% The satisfaction rate of each question mentioned above and the frequency of each score of each question will be evaluated and presented by groups of HC and MCI. |
