Clinical Trial Summary

In this research, a unique "Exergame" has been developed and is being tested. The Exergame consists of unique Virtual Reality Cognitive Training (VRCT) games combined with concurrent cycling on a recumbent stationary cycle. The Exergame seamlessly integrates specific cognitive tasks into a virtual environment and is synchronized with cycling to promote cognition. Cycling through an interesting virtual environment will motivate and engage the older adult to participate in the exercise, and VRCT could augment cycling's effects on cognition. A further innovation is that the Exergame has been developed as both an Apple TV and iPAD application, making it widely accessible and available. It will provide a low-cost VRCT Exergame option that currently does not exist, one that is affordable and compatible with almost any stationary cycle. This project is significant because treatment that delays the onset of Alzheimer's Disease (AD) by five years could save the U.S. economy an estimated $89 billion by 2030 and no drugs can yet prevent, cure, or even slow AD. Aerobic exercise and cognitive training are two such promising interventions. Emerging mechanistic studies further suggest that the two interventions together may have a synergistic, superior cognitive effect than either intervention alone. The purpose of this project is to demonstrate the feasibility and efficacy of the Exergame intervention on cognition. An RCT is planned in which subjects are randomized on a 2:1:1 allocation ratio to 3 parallel groups (exergame:cycling only:attention control). Mixed methods will be used to assess outcomes in both phases.


Clinical Trial Description

A treatment that delays the onset of Alzheimer's disease (AD) by five years could be hugely cost-saving at an estimated $89 billion in 2030. However, nearly all (99.6%) drug trials for AD have failed, and no drugs can yet prevent, cure, or even slow AD. This highlights an urgent and pressing need to develop behavioral interventions to prevent AD and slow its progression. Aerobic exercise and cognitive training are two such promising interventions.

Aerobic exercise and cognitive training are 2 promising interventions for preventing AD. Aerobic exercise increases aerobic fitness, which in turn improves brain structure and function, while cognitive training improves selective neural function intensively. Hence, concurrent aerobic exercise and cognitive training may very well have an additive or synergistic effect on cognition by complementary strengthening of different neural functions because aerobic exercise and virtual reality cognitive training depend on discrete neuronal mechanisms for their therapeutic effects.

The purpose of this Phase II randomized controlled trial (RCT) is to test the efficacy and additive/synergistic effects of a 3-month combined cycling and virtual reality cognitive training intervention on cognition and relevant mechanisms (aerobic fitness, physical function), in persons with subjective cognitive decline at risk for developing AD. ;
