Awakenings - which inspired the major motion picture - is the remarkable story of a group of patients who contracted sleeping sickness during the great epidemic just after World War I. Frozen for decades in a trance-like state, these men and women were given up as hopeless until 1969, when Dr. Oliver Sacks gave them the then-new drug L-DOPA, which had an astonishing, explosive, "awakening" effect. Dr. Sacks recounts the moving case histories of his patients, their lives, and their extraordinary transformations.

Have you ever seen something that wasn't really there? Heard someone call your name in an empty house? Sensed someone following you and turned around to find nothing? Dr Oliver Sacks weaves together stories of his patients and of his own mind-altering experiences to illuminate what hallucinations tell us about the organisation and structure of our brains, how they have influenced every culture's folklore and art and why the potential for hallucination is present in us all, a vital part of the human condition. 

Oliver Sacks' The Man Who Mistook His Wife for a Hat tells the stories of individuals afflicted with fantastic perceptual and intellectual aberrations: patients who have lost their memories and with them the greater part of their pasts; who are no longer able to recognize people and common objects; who are stricken with violent tics and grimaces or who shout involuntary obscenities; whose limbs have become alien; who have been dismissed as retarded yet are gifted with uncanny artistic or mathematical talents.

An exploration of vision through the case histories of six individuals - including a renowned pianist who continues to give concerts despite losing the ability to read the score, and a neurobiologist born with crossed eyes who, late in life, suddenly acquires binocular vision, and how her brain adapts to that new skill.

To these seven narratives of neurological disorder Dr. Sacks brings the same humanity, poetic observation, and infectious sense of wonder that are apparent in his bestsellers Awakenings and The Man Who Mistook His Wife for a Hat. These men, women, and one extraordinary child emerge as brilliantly adaptive personalities, whose conditions have not so much debilitated them as ushered them into another reality.
