How singing unlocks the brain

As Bill Bundock's Alzheimer's progressed he became more and more locked into his own world.

He withdrew into himself and stopped communicating with his wife, Jean.

Jean said Bill lost his motivation, and his desire and ability to hold conversations, but all this changed when the couple started attending a local sing-song group, aimed especially for people with dementia.

Jean said Singing for the Brain had unlocked Bill's communication block.
