Overview

• Researchers from Japan and the UK have developed the first VR cognitive training protocol integrating precise scent delivery for older adults.
• A single 20-minute session of the olfactory VR system improved visuospatial and memory task performance in a 30-participant study aged 63 to 90.
• Participants demonstrated measurable gains, including a 10-point increase in visuospatial rotation scores and enhanced spatial recall abilities.
• The protocol leverages olfactory stimulation's direct access to memory and emotion centers in the brain, targeting neural networks affected by aging.
• Efforts are underway to address the high cost and usability challenges of olfactory hardware to enable broader clinical and consumer adoption.
