We're all a bit crazy, and Dr. Allen's book is a easy read that helps one understand how, why and perhaps what we can and can't do about it.
His review of the various approaches to understanding and treatment of "mental disorders", by showing how far off the mark trusted physicians were in the past, helps make his point that just because everyone seems to think they've got the answers, it ain't necessarily so. The human mind is far too complex for simple explanations offered by many.
Once a person is thought to have a mental disorder, the treatment begins, and it is here that Dr. Allen is at his best, showing in a tongue-in-cheek manner, how the pharmaceutical industry has sought to exploit people's weaknesses for profit. He'll make you pause and think about your doctor's possible silent agenda next time you receive a prescription even if it has nothing to do with your mental state of mind.
Dr. Allen's key objective is to help the reader better understand what can and can't help those with mental disorders related to family situations; without a guide to the sand-traps, it is tough to improve your score.
In my opinion, Dr. Allen's book is recommended reading for those seeking to help themselves, family or friends with mental disorders as it facilities understanding the problems and issues in a manner that is both friendly and easily comprehensible
