Protocol of Virtual Interactive Memory-Training Program

Ministry of Science and Technology, Taiwan60 enrolled

Overview

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).

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.

Interventions

Virtual interactive memory trainingBEHAVIORAL

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.

Passive information activitiesBEHAVIORAL

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.

The clinical diagnosis of dementia was based on the DSM-IV-TR 2. Active in another cognitive or memory-related training in the past year 3. Comorbid medical conditions that would predispose them to imminent functional decline or cognitive impairment 4. A diagnosis of major neurological or psychiatric illness history and/or behavioral problems that would sufficiently impair performance to make participation impossible 5.
