Free the Mind follows neuroscientist Dr. Richard Davidson as he conducts an unusual experiment. Following the practices of Buddhist monks and the advice of the Dalai Lama, Dr. Davidson utilizes meditation and yoga in an attempt to physically alter the brains of veterans suffering from post-traumatic stress disorder (PTSD). To see how early in life these practices can take effect Dr. Davidson broadens the study to include children with attention deficit hyperactivity disorder (ADHD). Focusing on participants such as Steve, an ex-interrogator, and Rich, who led battalions in Iraq and Afghanistan, the film documents the promising effects of Dr. Davidson's non- medicinal methods of treating pain and anxiety, leading to relaxation and happiness. Free the Mind asks the question: Can you rewire the brain just by taking a breath?
