Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in the Mini-Mental State Examination (MMSE)	It is a 30-point questionnaire that is used extensively in clinical and research settings to measure cognitive impairment. The score is between 0-30. Higher score indicating better cognition.	12 weeks from baseline cognitive assessment
Primary	Change from baseline in the Memory tests	Immediate Recall, Delayed Recall, Delayed Recognition are tests that measure memory function. Higher score indicating better cognition.	12 weeks from baseline cognitive assessment
Primary	Change from baseline in the Trail Making test scores	Raw score, assessing attention, executive function. TMT is divided into two parts, TMT-A and TMT-B. In the TMT part A, circles with number from 1 to 25 are arranged randomly. Numerical sequence should be connected by patients as quickly as possible, cutoff value > 180 seconds. In the TMT part B, patients must alternate between numbers and letters, cut off value > 300 second. Cutoff scores indicate the value above suggest cognitive performance is normal.	12 weeks from baseline cognitive assessment
Primary	Change from baseline in the Digits Span forward and backward	The longest digits of forward and backward are 8 and 7, respectively. The total scores are twelve for each test. Higher score indicating better cognition.	12 weeks from baseline cognitive assessment
Primary	Change from baseline in the Verbal fluency test	Semantic memory score will be measured using the Verbal fluency test. The verbal fluency test is a short test of verbal functioning. Participants are given 1 min to produce as many animals as possible within a semantic category (category fluency). The participant's score is the number of animals. Higher score means better cognition.	12 weeks from baseline cognitive assessment
Primary	Change from baseline in the Clock drawing test	1-6 points, with higher scores indicating worse visuo-spatial function.	12 weeks from baseline cognitive assessment
Primary	Change from baseline in the 15-Item Version of the Boston Naming Test	Cognitive test of semantic memory. Object naming to confrontation, which also depends upon intact perceptual and word retrieval ability. Higher scores indicating better cognition.	12 weeks from baseline cognitive assessment
Primary	Change from baseline in the Instrumental Activities of Daily Living (IADL) score.	Instrumental Activities of Daily Living (IADL) is a questionnaire to assess patient's capacity to live independently.	12 weeks from baseline cognitive assessment
Secondary	Change from baseline in the Zarit Burden Interview (ZBI) score.	Zarit Burden Interview score is a questionnaire to assess patient's caregiver burden.	12 weeks from baseline cognitive assessment
Secondary	Percentage of participants completes the full 12-week cognitive training.	Every 4 weeks participants will follow-up at Dementia Center and be able to continue the training if they complete 80% of each level of difficulty workload. Therefore, we aim to calculate the percentage of participants who can completes the full 12-week cognitive training.	12 weeks from baseline cognitive assessment
