DOI: 10.3389/fnagi.2022.817889
Key Findings:
Sample Size: 121 musically naïve healthy elderly individuals (large randomized controlled trial)
Duration: 6 months of piano training vs. music listening/musical culture lessons
Main Result: Piano training stabilized white matter microstructure in the fornix (a brain region that naturally declines with age)
Control Group: The music listening group showed significant fiber density decline in the fornix after 6 months
Memory Connection: Changes in fiber density positively correlated with episodic memory task performance and amount of weekly piano training
Significance: Learning piano at an advanced age may stabilize white matter microstructure and protect against age-related decline
Background Context: Verghese et al. (2003) showed that frequently playing an instrument reduced the risk of developing dementia. The fornix is a main output tract of the hippocampus and is mainly involved in episodic memory. Age-related FD reductions in the fornix are well-documented. Musical training is associated with experience-driven brain plasticity and protection against age-related cognitive decline
Effects of Music Learning and Piano Practice on Cognitive Function, Mood and Quality of Life:

DOI: 10.3389/fpsyg.2013.00810
PMID: 24198804
Key Findings:
Duration: 4 months of piano lessons with daily training (n=13) vs. control group with other leisure activities (n=16)
Cognitive Benefits: Significant improvement on Stroop test (executive function, inhibitory control, divided attention)
Motor Benefits: Enhancement of visual scanning and motor ability (Trial Making Test part A)
Mental Health Benefits: Piano lessons DECREASED DEPRESSION and induced positive mood states
Quality of Life: Improved both psychological AND physical quality of life in elderly participants
Significance: Playing piano and learning to read music promotes cognitive reserve and improves subjective well-being
Important Context:
Reading music and playing piano is a complex activity involving motor andmultisensory integration (auditory, visual, somatosensory) Music has well-known impact on emotional state and can be highly motivating.Musical training is a useful framework to study brain plasticity
Results suggest piano can be a useful intervention in older adults
Playing Musical Instrument as Protective Factor Against Dementia:

DOI: 10.1155/2014/836748
Key Findings:
Study Design: Population-based twin study with 157 twin pairs discordant for
dementia and cognitive impairment
Main Result: Playing a musical instrument was significantly associated with 64% LESS likelihood of dementia and cognitive impairment (OR = 0.36, 95% CI 0.13-0.99)
Methodology: Cotwin control design - twins share genetic makeup and environmental exposures, reducing confounding factors
Significance: This finding supports music as a modifiable protective factor against dementia and cognitive impairment
Control Factors: Results controlled for sex, education, and physical activity
Important Context:
Dementia is caused by a combination of genetic and environmental influences throughout the lifespan.Twin studies provide unique advantage by matching genetic propensity (MZ twins share 100% genetics, DZ twins share 50%) Twins are typically reared together, so they're matched on environmental exposures during developmental years. In discordant twin pairs (where one had dementia), the unaffected twin was more likely to have played a musical instrument

DOI: 10.1186/s12883-022-02902-z
Published: October 27, 2022
Key Findings:
Study Type: Systematic review and meta-analysis of prospective cohort studies
Main Result: Playing a musical instrument was significantly associated with 36% DECREASED risk of dementia (HR = 0.64; 95% CI: 0.41, 0.98)
Studies Included: Three prospective cohort studies (two from U.S., one fromJapan)
Statistical Significance: No significant heterogeneity across studies (I² = 23.3%, p =0.27) and no publication bias detected
Extended Analysis: When pooling with cross-sectional studies, results remainedconsistent (Risk estimate = 0.68, 95% CI: 0.50, 0.92)
Background:Engaging in leisure activities has been suggested to protect older adults from dementia. This meta-analysis aimed to investigate the association between playing musical instruments and dementia risk in older adults. Provides strong evidence from multiple prospective cohort studies across different populations
