Auditory and cognitive performance in elderly musicians and nonmusicians

Area of Science:

• Neuroscience
• Cognitive Psychology
• Auditory Science

Background:

• Musicians serve as a valuable model for studying brain plasticity.
• Previous research has not extensively explored the auditory and cognitive profiles of elderly musicians compared to nonmusicians.
• Understanding age-related changes in hearing and cognition is crucial for maintaining quality of life.

Purpose of the Study:

• To investigate whether professional musicianship mitigates age-related declines in auditory and cognitive abilities.
• To compare the auditory performance and cognitive functions of active elderly musicians and nonmusicians.
• To identify specific auditory and cognitive tasks that can differentiate between older musicians and nonmusicians.

Main Methods:

• A comparative study involving active elderly musicians (≥65 years) and age-matched nonmusicians.
• Auditory assessments included absolute threshold, frequency intensity, duration and spectral shape discrimination, and gap and sinusoidal amplitude-modulation detection.
• Cognitive assessments covered short-term memory, working memory (WM), and visuospatial abilities.

Main Results:

• Older musicians exhibited similar absolute hearing thresholds but superior supra-threshold auditory discrimination in four of six tasks compared to nonmusicians.
• Musicians demonstrated enhanced working memory (WM) performance and stronger visuospatial abilities.
• No significant differences were observed in short-term memory between the groups.
• Frequency discrimination, gap detection, complex span WM tasks, and one visuospatial task effectively distinguished musicians.

Conclusions:

• Life-long musical training appears to be associated with preserved or enhanced auditory and cognitive functions in advanced age.
• These benefits extend to complex cognitive skills, including working memory and visuospatial abilities.
• Further research is needed to determine if musical training acts as a protective factor against age-related cognitive decline.
