There is The Diagnostic and Statistical Manual of Mental Disorders, which includes every single mental disorder, statistics in terms of gender, what the age of onset is and prognosis as well as some research concerning the optimal treatment approaches.
This book is considered the "bible" of any modern-day psychiatrist.
In this press release it states that not only have psychiatrists never run blood tests on their patients to enable them to diagnose such mental illness, they vote each disease in the "bible" into existence and they are allowed to vote it out if it causes them too much trouble! These are the people who are considered "doctors" when it comes to mental illness! How can they be allowed to carry on as they are, when all they do to "locate" mental illness is to get together and vote on it?
Please take a look for yourself. Don't let people who would take a vote on your sanity be in charge of mentally ill patients.
