The Man Who Mistook His Wife for a Hat - Oliver Sacks

I must admit I had heard of the book, and assumed it was a semi-humorous novel (in my defence, I suspect I wasn't the only one) and not a series of case-studies, narrated with remarkable tact, covering the stories of a number of psychiatric patients. 

This book ended up being a very "informative" read, if one can label it as such, despite really not being what I had initially envisaged. The loss - of control, of inhibitions, and often of self - of the people described in the chapters is absolutely terrifying and has remained with me for quite some time. 

Yet, like a lot of other people, I suspect. This book (un)covers aspects of human life and illnesses that I find so disturbing that I would almost prefer not to think about them (not something that I am proud of, but something that I still need to acknowledge).
