Summary

Alzheimer's disease and related dementias (AD/ADRD) greatly affect memory and daily activities in older adults. Mild Cognitive Impairment (MCI) is an early stage of dementia, affecting about 17% of older adults. People with MCI often show problems with gait and balance, which doubles their risk of falling compared to cognitively healthy peers. Falls can cause injuries, increase sedentary behavior, and reduce physical activity. This decline in activity can also speed up the progression from MCI to dementia. Exercise can help older adults make healthy lifestyle changes; however, most of the existing exercise programs focus mainly on physical movement rather than cognitive function. Therefore, the investigators developed a new program that uses computer vision and a cloud-based system to provide more scalable, engaging, and personalized cognitive-motor training for OAwMCI. The purpose of this study is to investigate the short- and long-term effects of a novel CogXergaming training (CXT) paradigm for improving the cognitive-motor function, physical activity, falls efficacy, and quality of life.

Detailed description

Alzheimer's disease/Alzheimer's disease and related dementias (AD/ADRD) significantly impair cognitive function and the ability to perform activities of daily living in older adults. Mild Cognitive Impairment (MCI) is a transitional phase between age-associated cognitive decline and dementia, which affects about 17% of older adults and can impair multiple domains of cognitive functioning (executive function, memory, etc.). Further, there is a well-established relationship between cognitive decline and reduced mobility, and OAwMCI show gait and balance deficits compared to cognitively intact older adults (CIOA), resulting in a 2-fold increase in the risk of falling. Fall-related consequences (e.g., injury) can significantly increase sedentary behavior and reduce physical activity, thus leading to a vicious cycle of deconditioning and reduced mobility, which significantly increases the risk of experiencing another fall. Further, sedentary behavior and deconditioning can accelerate the rate of conversion from MCI to AD/ADRD. Exercise interventions are a promising approach to not only improve motor function, balance, and mobility in OAwMCI but also to improve cognitive function via several mechanisms of action. However, few exercise interventions for OAwMCI explicitly target cognitive processing in challenging conditions, such as dual tasking (i.e., simultaneous motor+cognitive task). Exergaming is a form of dual-task training that could reduce CMI in OAwMCI by providing combined cognitive stimulation and motor training in challenging environments that activate multiple cognitive processes, using digital gaming platforms. However, most existing exergames have focused only on the physical domain (promoting physical activity or exercise), and there is limited evidence on whether exergaming yields more cognitive benefit than conventional training. To explicitly target cognitive function and dual tasking ability, the investigators have developed a novel paradigm that integrates advanced computer vision technology and a cloud-based platform to provide more scalable, engaging, and customizable cognitive-motor training for OAwMCI. This CXT paradigm overcomes barriers of commercial exergaming systems (Wii Fit, Kinect) and requires minimal technology (webcam, computer/tablet), thus being more scalable and cost-effective. The current proposal will examine the effects of 8 weeks of CXT on dual tasking ability, balance, and mobility, and patient-centered outcomes in OAwMCI, compared to an exercise and education program (EEP). Aim 1: Examine the immediate effects of CXT on mechanistic measures of CMI in OAwMCI by comparing the dual task costs during both volitional and reactive balance tasks between groups after 8 weeks of training. Aim 2: Examine the immediate effects of CXT on dynamic balance, mobility, and endurance in OAwMCI, and the investigators will also compare the cognitive function using the NIH cognitive toolbox between groups immediately after the training (Ancillary Aim). Aim 3: Examine the immediate and sustained effects of CXT on patient-centered measures of physical activity, falls efficacy, and quality of life, and examine whether reductions in CMI (Aim 1) and improved balance, mobility, and endurance (Aim 2) will mediate improvements in patient-centered outcomes. Exploratory analysis: To understand stakeholder (participants, clinicians) perceptions regarding CXT and facilitators/barriers for translation of the intervention into home and community settings, focus groups will be conducted to assess system usability, acceptability, attitudes, and intrinsic motivation via self-reported questionnaires and recorded transcripts.

Interventions

Type	Name	Description
BEHAVIORAL	Novel CogXergaming Training	In each session, participants will play 6 games in the same order (Fruit catch, Math, Tracking, Candy match, Letter Number Sequencing - LNS, Stroop), each of which contains 10-20 trials and will last for around 10 minutes (total = 60 minutes. The CXT program employs a progressive method to ensure the intensity of CXT remains challenging without overload. If a participant demonstrates ≥80% accuracy in 3 continuous trials for one game, then the exercises for this game will be progressed to the next level (levels: 1-9 in Table 3). Each session of CXT will last approximately 1 hour. At least one day of rest will be required between weekly training sessions.
BEHAVIORAL	Exercise and Education Training Program	EEP consists of a conventional exercise program and fall-prevention education. The conventional exercise program comprises 50 minutes of supervised exercises for stretching and strengthening. A fall-prevention education program will also be provided to Group B, for about 10 minutes after each session of the exercise program. Each session of EEP will last approximately 1 hour. At least one day of rest will be required between weekly training sessions.
