Words and music, such natural partners that it seems obvious they go together. Now science is confirming that those abilities are linked in the brain, a finding that might even lead to better stroke treatments. Studies have found overlap in the brain's processing of language and instrumental music, and new research suggests that intensive musical therapy may help improve speech in stroke patients, researchers said Saturday at the annual meeting of the American Association for the Advancement of Science. In addition, researchers said, music education can help children with developmental dyslexia or autism more accurately use speech. People who have suffered a severe stroke on the left side of the brain and cannot speak can sometimes learn to communicate through singing, Gottfried Schlaug, associate professor of neurology at Harvard Medical School told the meeting.
