This book is a collection of some of the most bizarre, fascinating, and at times heartbreaking stories of people afflicted with a variety of neurological disorders. We learn about patients 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; and who have been dismissed as retarded yet are gifted with uncanny artistic or mathematical talents.
