Music Activates Brain Regions
Music brings back memories. It may that first dance with someone special or the excitement of an orchestra at the 4th of July celebration. Music activates brain regions and recent research has shown a connection between music and brain regions undamaged by Alzheimer’s disease.
Ever get chills listening to a particularly moving piece of music? You can thank the salience network of the brain for that emotional joint. Surprisingly, this region also remains an island of remembrance that is spared from the ravages of Alzheimer’s disease. Researchers at the University of Utah Health are looking to this region of the brain to develop music-based treatments to help alleviate anxiety in patients with dementia. Their research will appear in the April online issue of The Journal of Prevention of Alzheimer’s Disease.
“People with dementia are confronted by a world that is unfamiliar to them, which causes disorientation and anxiety” said Jeff Anderson, M.D., Ph.D., associate professor in Radiology at U of U Health and contributing author on the study. “We believe music will tap into the salience network of the brain that is still relatively functioning.
”Previous work demonstrated the effect of a personalized music program on mood for dementia patients. This study set out to examine a mechanism that activates the attentional network in the salience region of the brain. The results offer a new way to approach anxiety, depression and agitation in patients with dementia. Activation of neighboring regions of the brain may also offer opportunities to delay the continued decline caused by the disease.
For three weeks, the researchers helped participants select meaningful songs and trained the patient and caregiver on how to use a portable media player loaded with the self-selected collection of music.
“When you put headphones on dementia patients and play familiar music, they come alive,” said Jace King, a graduate student in the Brain Network Lab and first author on the paper. “Music is like an anchor, grounding the patient back in reality.”
