THE CONCUSSION CRISIS brings an explosive but largely unseen epidemic out of the shadows. It puts a human face on a pressing public health crisis through poignant stories of athletes (from the peewees to the pros), soldiers, and others whose lives have been forever changed by jolts to the head and brain. Weaving their cautionary tales with a clear and accessible explanation of the advancing science and medicine, The Concussion Crisis is the definitive exploration of the invisible injury behind today’s alarming headlines. Journalists Linda Carroll and David Rosner sound an urgent wake-up call to every family and argue for changing a macho culture that refuses to treat concussion seriously as the traumatic brain injury it is.
