Music engagement is a ubiquitous activity that is thought to have cognitive benefits for the rapidly aging population. In the absence of robust treatment approaches for many age-related and neuropathological health issues, interest has emerged surrounding lifestyle-enriching activities, like exercise and music engagement, to build cognitive reserve across the lifespan and preserve neurocognitive function in older adults. The present review evaluates evidence of neurocognitive preservation arising from lifelong music engagement with respect to the cognitive reserve hypothesis. We collated a body of neuroimaging, behavioral and epidemiological evidence to adjudicate the benefits of music engagement for cognitive reserve. The findings suggest that music engagement should be considered in tandem with other well-established cognitive reserve proxies as a contributor to differential clinical outcomes in older populations at risk of age-related and neuropathological cognitive decline.
