The Man Who Mistook His Wife for a Hat Summary

In *The Man Who Mistook His Wife for a Hat*, neurologist Oliver Sacks presents a landmark collection of clinical case studies drawn largely from his own practice in New York. The book takes its title from its opening case: a music teacher and singer, referred to as Dr. P., who suffers from visual agnosia so profound that he cannot identify everyday objects or faces, at one point grasping his wife’s head while attempting to put on his hat. Sacks uses this case to explore how the brain constructs perception, showing that Dr. P. had lost the ability to form visual “schemas” even as his other faculties remained intact. The collection is divided into four sections—Losses, Excesses, Transports, and The World of the Simple—grouping patients by the nature of their neurological conditions. Sacks examines disorders including prosopagnosia, phantom limb syndrome, Korsakoff’s syndrome, Tourette’s syndrome, and severe memory loss. One widely discussed patient is Jimmie G., a former submariner who believes he is still a young man in 1945 and cannot retain new memories beyond a few seconds. Another is William Thompson, a patient with Korsakoff’s whose confabulations Sacks interprets not as mere lies but as an attempt to maintain a coherent self. Throughout, Sacks argues against reducing patients to their deficits. Drawing on his training and his admiration for the neurologist Alexander Luria, he insists that even profound neurological loss can coexist with preserved identity, creativity, and meaning. First published in 1985, the book became a bestseller and remains one of the most influential works of popular neuroscience, celebrated for treating its subjects as whole persons rather than as curiosities.
