Therapeutic treatment is yet available for declining memory, which is an impairment affecting the quality of life for many older adults and patients with cognitive impairment. Cognitive training with an immersive, virtual reality video game promises to drive hippocampal-cortical plasticity and associated gains that can restore memory capability or provide therapeutic treatment for memory deficits.

Official Title

Cognitive Intervention (VR) to Restore Capabilities for Learning and Retrieval of High-Fidelity Memory


A hallmark of higher cognition is the capability for flexible association of diverse bits of information stored in memory, such that experiences can be remembered in detailed and distinct terms (i.e., high-fidelity LTM). Interventions capable of sustaining improved learning and flexible association of new information into LTM remain elusive. Interventions have yet to be developed to attenuate the decline of high-fidelity LTM in normal aging or provide therapeutic treatment for patients with cognitive impairment without dementia (i.e., MCI). This project applies a translational neuroscience approach in development of a cognitive training intervention that targets sustained improvement in capabilities for long-term memory (LTM) and cognitive control. Treatments use commercially available head-mounted display Virtual Reality (VR) technology for deeply immersive presentation of a spatial wayfinding video game. The hypothesis is that immersion in a game to navigate errands through unfamiliar, visually complex neighborhoods (i.e., wayfinding) will be an effective means to environmental enrichment, which refers to a process whereby new and complex experiences bring change to brain and behavior. The significance of this platform is in value to both gains from cognitive training that can generalize to improvements in untrained capability for high-fidelity LTM and clinical assessments for patients with memory deficits. Research in rodents and humans shows that healthy function of the hippocampus supports lifelong neurogenesis, which has been linked as the neurobiological basis to formation of new, high-fidelity memories. The VR spatial wayfinding game was developed in-house to incorporate full scientific rigor, as with procedures in any properly controlled behavioral experiment. The game uses both VR computer graphics tools and numerous levels of adaptive challenge to deliver a dynamic, engaging experience for participants throughout the training regimen. A participant's pre- and post-training assessments will occur promptly before and after their 15-hour training regimen, including collection of functional MRI (fMRI) data and blood-drawn biospecimens. Cognitive outcome measures will assess capabilities for high-fidelity LTM retrieval. Effectiveness of the VR wayfinding game intervention will be evidenced by post-training improvements in retrieval of high-fidelity LTM and associated cognitive control capabilities. FMRI results associated with the measured cognitive improvements will localize changes in functional brain networks that support gains in memory capabilities. Neuronal-derived exosome factors will provide confirmatory evidence of a hippocampal-dependent mechanism of action stimulated by the training regimen.
