简要总结
The overarching goal of this pilot clinical trial is to use a novel virtual reality (VR)-based intervention that simultaneously engages physical and cognitive activity aimed at improving brain and cognitive outcomes in older adults. Physical activity is a promising lifestyle intervention for mitigating cognitive decline or delaying onset of dementia. However, to fully leverage beneficial brain effects of physical activity, training the brain to learn and engage in a cognitively stimulating environment may be the key to enhanced brain and cognitive outcomes.

结局指标
主要结局
Mnemonic Similarity Task for visual memory performance - discrimination index
时间窗: 12 weeks
With the study's primary focus on hippocampal function, we will use the Mnemonic Separation Task (MST), a hippocampus-dependent discrimination test of similar objects, as our primary cognitive outcome.
Magnetic Resonance Image (MRI) brain scan of hippocampal volume (cubic mm)
时间窗: 12 weeks
The hippocampus has been shown to be a selectively vulnerable region in Alzheimer's Disease (AD), and several studies, including our own, identified a dysfunctional brain signal in the hippocampus in Mild Cognitive Impairment (MCI) patients. We propose to examine the effects of exercise on remediating this hyperactive signal exhibited in MCI patients.
