A study reported in Nature Clinical Practice Neurology
:238-39 (summarizing a study published in Brain
:866-76) found that stroke patients who listened to music (at least 1 hour per day for 2 months, during the acute recovery phase) showed greater recovery of verbal memory and focused attention than the control group or the group that listened to audio books for the same amount of time. The music group also showed less confusion and depression.
Fortunately, composers are not required to obtain FDA approval for new music...
