The relationship between playing musical instruments and cognitive trajectories: Analysis from a UK ageing cohort

BackgroundThe accumulation of age-associated cognitive deficits can lead to Mild Cognitive Impairment (MCI) and dementia. This is a major public health issue for the modern ageing population, as it impairs health, independence and overall quality of life. Keeping the brain active during life has been associated with an increased cognitive reserve, therefore reducing the risk of cognitive impairment in older age. Previous research has identified a potential relationship between musicality and cognition.ObjectivesExplore the relationship between musicality and cognitive function in a large cohort of older adults.MethodsThis was a nested study within the PROTECT-UK cohort, which collects longitudinal computerised assessments of cognitive function in adults over 40. Participants were invited to complete the validated Edinburgh Lifetime Musical Experience Questionnaire (ELMEQ) to assess their musical experience and lifetime exposure to music. Linear regression analysis was performed using cognitive data from PROTECT-UK.ResultsAnalysis identified an association between musicality and cognition in this cohort. Playing a musical instrument was associated with significantly better performance in working memory and executive function. Significant associations were also found between singing and executive function, and between overall musical ability and working memory.ConclusionsOur findings confirm previous literature, highlighting the potential value of education and engagement in musical activities throughout life as a means of harnessing cognitive reserve as part of a protective lifestyle for brain health. Playing a musical instrument was associated with significantly better working memory and executive function. Singing and overall musical ability was associated with more favourable cognition. Engagement with musical activities should be considered as part of public health initiatives to promote a protective lifestyle for brain health.
