Neurologist Sara Manning Peskin discusses her book, A Molecule Away From Madness: Tales of the Hijacked Brain, about how the very molecules that allow us to exist can also sabotage our minds.

Dr. Peskin recounts gripping tales of unruly molecules and the diseases that form in their wake. A college student cannot remember if she has eaten breakfast; by dinner, she is strapped to a hospital bed, convinced she is battling zombies. A man planning to propose marriage instead becomes violently enraged, gripped by body spasms so severe that he nearly bites off his own tongue. One after another, poor farmers in South Carolina drop dead from a mysterious epidemic of dementia.

From to Alzheimer's Disease to hallucinations, A Molecule Away from Madness is an unputdownable journey into the deepest mysteries of our brains.
