Why Playing Music May Help Ward Off Cognitive Decline of Aging
A new study has uncovered crucial knowledge about why playing a musical instrument can help older adults retain listening skills and ward off age-related cognitive declines.
Researchers at Baycrest Health Sciences in Toronto say the study’s findings could lead to the development of brain rehabilitation interventions through musical training.
Published in the Journal of Neuroscience, the study found that learning to play a sound on a musical instrument alters the brain waves in a way that improves a person’s listening and hearing skills over a short time frame. This change in brain activity demonstrates the brain’s ability to rewire itself and compensate for injuries or diseases that may hamper a person’s capacity to perform tasks, the researchers explained.
“Music has been known to have beneficial effects on the brain, but there has been limited understanding into what about music makes a difference,” said Dr. Bernhard Ross, a senior scientist at Baycrest’s Rotman Research Institute (RRI) and senior author on the study.
“This is the first study demonstrating that learning the fine movement needed to reproduce a sound on an instrument changes the brain’s perception of sound in a way that is not seen when listening to music.”
The study involved 32 young, healthy adults who had normal hearing and no history of neurological or psychiatric disorders.
The brain waves of participants were first recorded while they listened to bell-like sounds from a Tibetan singing bowl, a small bell struck with a wooden mallet to create sounds. After listening to the recording, half of the participants were provided the Tibetan singing bowl and asked to recreate the same sounds and rhythm by striking it and the other half recreated the sound by pressing a key on a computer keypad.
“It has been hypothesized that the act of playing music requires many brain systems to work together, such as the hearing, motor and perception systems,” said Ross, who is also a medical biophysics professor at the University of Toronto. “This study was the first time we saw direct changes in the brain after one session, demonstrating that the action of creating music leads to a strong change in brain activity.”
The study’s next steps will involve analyzing recovery between stroke patients with musical training compared to physiotherapy and the impact of musical training on the brains of older adults, according to the researcher.
