It has been two months since the Tucson shooting spree that killed six people and injured 12, including Arizona Rep.Gabrielle Giffords. Now Giffords, who survived a gunshot wound to the left hemisphere of her brain, is finding her voice through song.
"Gabby responds to music because she knows a lot of songs," said Maegan Morrow, Giffords' music therapist and a certified brain injury specialist at TIRR Memorial Hermann Rehabilitation Hospital in Houston. Since Giffords was transferred to TIRR Jan. 21, reports of her singing "Happy Birthday" for husband Mark Kelly and Don McLean's "American Pie" have signaled what some have called a miraculous recovery.
"The brain can heal itself if you do the right protocol," Morrow said. "It just needs lots of repetition, lots of consistency." Protocols like music speech stimulation and melodic intonation therapy can help patients with damage to the brain's communication center, like Giffords, learn to speak again. "It's creating new pathways in the brain," Morrow said. "Language isn't going to work anymore, so we have to go to another area and start singing and create a new pathway for speech."
Music therapy was first recognized as a tool to aid soldiers returning from World War II with brain injuries. "It was discovered that music was more that a diversion or recreational activity -- it could be incorporated into the overall treatment of an individual," said Al Bumanis, director of communications for the American Music Therapy Association. "It could address non-musical goals in a very unique way -- sometimes coming in through the backdoor where some therapies can't." Indeed, a person who has suffered an injury due to stroke or trauma may have difficulty speaking but be able to sing.
Music Can Rewire the Brain
Evidence supporting a healing role for music in the recovery from brain injury is mounting. But many people remain skeptical, and few insurers will cover it.
"I think the name, 'music therapy,' is a barrier. Most people are like 'what is that?' It sounds childish," Morrow said. "I know that it really works. They're already seeing that healing in Gabby."
Music is very closely linked with language. Some people believe that we may have started to sing before we started to speak, De Georgia said, citing "The Singing Neanderthal: The Origins of Music, Language, Mind and Body," by British archaeologist Steven Mithen.
Music is also linked to brains areas that control memory, emotions, and even movement.
"The thing about music is that it's something that's very automatic -- part of our old brain system," Morrow said. "If I play a rhythm, I can affect the rest of the body. The body naturally aligns with a rhythm in the environment."
