Oliver Sacks on 5 Common Types of Hallucinations

Hallucinations - Review

This is a great book review, Dr Stokes! I need to say, Oliver Sacks' books are amazing, but this one is particulary good. Hallucinations are still insufficently understood and sometimes society thinks that thy are the nucleus of psychiatric disorders such as schizophrenia but they aren't. Thank You for this great article, it is really interesting. I have one question- do You recognize the division of hallucinations into negative and positive?

Hallucinations is a book written by the neurologist Oliver Sacks. In Hallucinations , Sacks recounts stories of hallucinations and other mind-altering episodes of both his patients and himself and uses them in an attempt to elucidate certain features and structures of the brain [1] including his own migraine headaches.

Kermit meant nothing to her, she said, and his shifting moods — sometimes he looked sad, sometimes happy, occasionally angry — had nothing to do with her own feelings. In the beginning, he occupied most of the left half of her visual field, but he gradually began getting smaller. He describes visual hallucinations, auditory hallucinations, olfactory hallucinations and hallucinations produced by illness, fevers, sleep deprivation, drugs, grief, trauma and exhaustion. Sacks conjures these apparitions in language that has an easy, tactile magic. At the same time, his compassion for his patients and his own philosophical outlook turn what might have been clinical case studies into humanely written short stories, animated as much by an intuitive appreciation of the human condition as by scientific understanding. As a young doctor in California in the s, Dr.

H allucinations are much more common than most people realise and in fact, may be a universal part of the human experience. In his page book, Sacks makes it plain that he is focusing on hallucinations that may result from "organic" disorders, such as migraines, delirium, epilepsy, drug use or certain medical conditions, like blindness or Parkinsonism, avoiding any mention of the hallucinations experienced by those diagnosed with schizophrenia and bipolar disorder. The main point of the book that the brain is a thrill-seeker, in constant need of stimulation, and when that stimulation is lacking, the brain generates hallucinations to meet this need. For example, deficits in one of our five senses is a common hallucinatory trigger. People who have been partially or completely blind for years may suddenly see vivid and frequently exotic although silent visual hallucinations. Deaf people may hear music.

In , psychologist David Rosenhan conducted a controversial and now-famous experiment. Rosenhan instructed eight healthy people to go to emergency rooms around the United States and pretend to hear voices. The voices were not threatening, nor did they instruct these people to act in any dangerous way. Despite that they lacked any other symptoms or psychiatric history, all eight were admitted — some for weeks — and prescribed antipsychotic medications. The doctors who hospitalized them reasoned: "What else besides major mental illness could possibly cause someone to perceive things that aren't really there? In this fascinating and engaging "anthology of hallucinations," Sacks uses the unique mixture of patient anecdote, memoir, scientific information, and broad reference to literature, art, music, history, and philosophy that has characterized all his work to explore various types of visual, auditory, tactile, and other illusory sensations — excluding those caused by mental illness. Sacks begins by describing Charles Bonnet syndrome, a condition in which people with impaired eyesight experience visual hallucinations.
