The Man Who Mistook His Wife for a Hat and Other Clinical Tales by Oliver Sacks is a novel presenting twenty-four individual cases of neurological disorders collected by Oliver Sacks himself, a well-known physician and neurologist. It is divided into four sections, which include a number of cases related to each section. These include: losses, excesses, transportation and the world of the simple. The first section of the book, Losses, focuses on a number of patients who have deficits or losses, such as aphonia, aphemia, aphasia, alexia, apraxia, agnosia . , Amnesia and Ataxia. These terms refer to neural and mental functions that patients have been deprived of due to a specific incident or developmental failure (Sacks 3). In The Man Who Mistook His Wife for a Hat, Mr. P, a well-known musician, is incapable of perceiving things as whole objects. His distinct inability carries over to people as well, as he cannot recognize anyone unless they have some sort of distinguishing feature. Such visual impairment was somewhat unknown at the time. The Lost Mariner is about a man who is convinced that he is still nineteen years old and in the navy. He is unable to remember people or events after the year 1945. Jimmie G. can, however, solve complex puzzles quite quickly and is good at checkers, which perplexes Dr. Sacks. In Eyes Right!, Mrs. S., sixty years old, suffered a stroke which damaged the right half of her cerebral hemisphere. As a result, she cannot perceive her left side. She only wears makeup on the right side of her face and leaves uneaten food on the left side of her plate. There are six more interesting tales left in this section. Excess, the second section of the book, is quite the opposite of the first section...... middle of paper ......soft singer. The only exception was that the things Martin remembered contained no emotion; they made almost no sense to him. It was only when he returned to church, where he was able to sing and direct the church choir, that he apparently rediscovered himself and thus became much more alive despite his lateness . The autistic artist is about a man named José who was retarded and suffered many seizures. Even though he didn't speak, he could draw pictures in great detail. His doctors came to the conclusion that he was autistic, but it was not a one hundred percent accurate diagnosis. His seizures continued to get worse and his mother quickly decided that she didn't want him to leave the house, in case he had a seizure away from home. Being isolated indoors proved too difficult for José, who became hysterical. After that he was taken to the hospital.
