Believe it or not, yes! According to The Brain and Music website, music helps brain injury victims with vocalization, orientation, and re-organizing of the structure of the brain. Research has indicated that listening to music, especially that of composers with highly organized styles of music (like Mozart), helps children and adults with brain injuries to organize their thoughts and activities better (and their emotions as well). Why? Music has been proven to be processed by the entire brain, mainly due to its structure.
Other benefits of music on brain-injured children are improvements in rhythmic movements, self-esteem, self-expression, and relaxation. In addition to needing medical rehabilitation, children who have suffered brain injuries may need emotional and mental rehabilitation, as well, making all the benefits of music listed here important ones.
