Older adults' brains 'rewarded' by music they don't even like, B.C. researcher finds

The brains of older adults feel a sense of reward when listening to music, even if it's a song they don't particularly like, a researcher at British Columbia's Simon Fraser University says.

The brains of older adults feel a sense of reward when listening to music, even if it's a song they don't particularly like, a researcher at British Columbia's Simon Fraser University says.

Sarah Faber said her work on how healthy brains respond to music as they age creates a baseline for future research on people who have Alzheimer's or dementia to better understand those diseases.

“There's a lot of interest in how to predict who might be going to develop dementia or Alzheimer's disease and then once people do develop Alzheimer's and dementia, who is going to respond to treatment and what kind of treatment,” she said.

“The brain is fascinating, but it doesn't exist in a jar. It's attached to a body, that's attached to an environment, and community, and a social structure.”

The research published in the journal Network Neuroscience featured 80 participants, including university students and people as old as 90, who took functional MRI scans.

The younger group of adults had an average age of 19, while the other group had an average age of 67.

Everyone listened to 24 samples, including songs they selected themselves, popular music intentionally chosen by researchers and songs composed specifically for the study.
