Music therapy is used widely for rehabilitation of patients that have had a stroke. A study reported by Brain Journal of Neurology by the Oxford University Press stated that incorporating music into standard stroke rehabilitation treatments helps improve recovery of speech and memory.
Specifically, when comparing treatment of music to either language therapy or no alternative therapy, the music had a more significant impact on recovery than the use of audio books or no additional stimuli at all. The study also showed that the music lightened the spirits of patients.
