Studying Music's Impact on Anxiety

Seth Link has been drumming since he was a toddler. Like many with Williams Syndrome he uses music for expression.
"You have all this energy and stuff, and you want to be able to experience it, you know, and to share it with other people," Link said.
The condition affects an estimated one in 7,500 babies. For people with Williams Syndrome, a missing part on the seventh chromosome can lead to learning disabilities and heart trouble. They have another trait, extreme friendliness and empathy, to the point of being less able to detect risky situations or ill intentions in others.
