The brain still responds to favorite music in dementia
What happens in the brain of someone with dementia when they hear music that means something to them? Researchers from Alzheimer Center Amsterdam and the Netherlands Institute for Neuroscience mapped how the brain responds to personally meaningful music. They found that favorite music evokes a stronger brain response than neutral music—and that this response differs between types of dementia.
Researchers from the Alzheimer Center Amsterdam and the Netherlands Institute for Neuroscience have discovered that music that holds personal significance can still trigger a strong brain response in individuals with dementia. This finding, published in the journal Brain Communications, suggests that favorite music continues to evoke emotional and memory-related activity in the brain, even when the brain is affected by conditions such as Alzheimer's disease or frontotemporal dementia (FTD).
The study, which involved functional magnetic resonance imaging (fMRI) scans, found that participants with these dementias showed greater brain activity when listening to their personally meaningful music, compared to neutral music. Moreover, the brain response in individuals with Alzheimer's disease was more similar to that of healthy participants, while those with FTD exhibited reduced activity in the supplementary motor area, a region involved in movement and musical processing.
These results highlight the importance of the personal meaning of music for people with dementia, even when the brain is impaired. While further research is needed to fully understand the variations in brain responses across different types of dementia, this study underscores the potential benefits of music therapy as a nonpharmacological intervention to improve well-being and alleviate symptoms in individuals with dementia.
