Protocol of Virtual Interactive Memory-Training Program

Study Overview
=================
Brief Summary
-----------------
This study sought to investigate the changes in objective memory performance (including immediate recall and delayed recall), subjective memory complaints and degree of depression in older adults with mild cognitive impairment after Virtual interactive memory training (VIMT).

Detailed Description
-----------------
This double-blind randomized controlled study has a 2-arm parallel group design. All subjects will be randomized by the block randomization, into intervention group (Virtual interactive memory training, VIMT), or active control group (Passive information activities, PIA). Training sessions of the VIMT group are 45 minutes/day, 3 days/week, for 12 weeks (36 sessions each). The training of PIA group is the same as VIMT group. We constructed a rigorous VIMT program adhering to the Consolidated Standards of Reporting Trials (CONSORT) reporting guidelines. The investigators expect to determine the improvement in memory function and degree of depression of older adults with mild cognitive impairment after using the VIMT.

* Behavioral: Passive information activities


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Participants must endorse at least two items from a list of frequent subjective memory complaints by patient and/or an informant Objective memory impairment on neuropsychological tests of memory 1.5 SD or more below age/education norms Clinical neurologic examination by the Mini-Mental State Examination (MMSE) score of 24 or higher, and cut-off score of 23/24 on the Montreal Cognitive Assessment (MoCA) No impairment in personal activities of daily living (P-ADL) as determined by clinical interview with participant and family Exclusion Criteria: The clinical diagnosis of dementia was based on the DSM-IV-TR Active in another cognitive or memory-related training in the past year Comorbid medical conditions that would predispose them to imminent functional decline or cognitive impairment A diagnosis of major neurological or psychiatric illness history and/or behavioral problems that would sufficiently impair performance to make participation impossible Severe losses in vision, hearing, or communicative ability

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Virtual interactive memory training<br>Training sessions of the VIMT group are divided into initial training and booster training. Each training session is 45 minutes/day, 3 sessions/week, for 12 weeks for both initial training and booster training (36 sessions each). | Behavioral: Virtual interactive memory training<br>* Training sessions of the VIMT group are divided into initial training and booster training. Each training session is 45 minutes/day, 3 sessions/week, for 12 weeks for both initial training and booster training (36 sessions each). The training content of the four memory training include: (1) spatial encoding memory training task, (2) updating-spatial memory training task, (3) updating-visual memory training task, and (4) rehearsal-visuospatial memory training task.<br>* Other names: Memory training;|
| Active Comparator: Passive information activities<br>The training of active control group is the same as VIMT group (45 min/day, 3 days/week, for 12 weeks, for a total of 36 sessions). The active control group receives only the initial training. | Behavioral: Passive information activities<br>* The active control group (Passive information activities) only accepts the initial training phase, which training content of the two types to include: (1) listening to audio books, and (2) reading online newspaper.<br>* Other names: Active control group;|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in objective memory performance as measured by the Chinese version of the Wechsler Memory Scale-III (WMS-III). |  | Change from baseline in objective memory performance at Immediate post-test, 3 months, 6 months and one year after intervention. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in subjective memory complaints as measured by the Multifactorial Memory Questionnaire (MMQ). |  | Change from baseline in subjective memory complaints at Immediate post-test, 3 months, 6 months and one year after intervention. |
