“Playing an instrument is a unique activity in that it requires a wide array of brain regions and cognitive functions to work together simultaneously, throughout both the right and left hemispheres,” co-author Alison Balbag, PhD, told Psychiatry Advisor. While the study did not examine causal mechanisms, “playing an instrument may be a very effective and efficient way to engage the brain, possibly granting older musicians better maintained cognitive reserve and possibly providing compensatory abilities to mitigate age-related cognitive declines.”
She notes that clinicians might consider suggesting that patients incorporate music-making into their lives as a preventive activity, or encouraging them to keep it up if they already play an instrument.
Further research, particularly neuroimaging studies, is needed to elucidate the mechanisms behind the effects of music on dementia, but in the meantime it could be a helpful supplement to patients’ treatment plans. “Music has considerable potential and it should be introduced much more in rehabilitation and neuropsychological assessment,” Kerer said.
