The adult brain is the apotheosis of the human intellect, but what of emotion? The study of emotion was once relegated to the backwaters of neuroscience, a testament to the popular conception that what we feel exists outside our brains, acting only to intrude on normal thought.

Alzheimer's disease -- the most feared of all maladies, with no way to cure, stop or even slow its insidious progression. But now, after decades of perseverance in the lab, researchers are on the cusp of a scientific breakthrough that could be the first step toward making Alzheimer's itself a distant memory. In the gripping new documentary Turning Point, acclaimed filmmaker James Keach takes us inside the quest for the first medication that that could treat the underlying process of Alzheimer's disease, more than a century after Dr. Alois Alzheimer first described the brain disorder that slowly destroys memory and cognitive skills. Along the way, we meet the people behind these grand experiments, the scientists driven as much by personal conviction as professional innovation. And we discover why medical science is never easy, often unpredictable and potentially perilous.
