But why did anyone ever treat the Diagnostic and Statistical Manual of Mental Disorders as a Bible anyway?:
Only 3 per cent of DSM disorders have any known biological causes. The causes of the remaining 97 per cent – and this includes depression, anxiety, schizophrenia, attention deficit hyperactivity disorder (ADHD), bipolar and all personality disorders – are not known. The theory that chemical imbalances cause mental illness – that a serotonin deficiency causes depression, for example – is unproven. Billions of research dollars have been spent on trying to establish a link between neurotransmitters and mental disorder, and the attempts have failed. For all the scientific terminology, psychiatric diagnoses are based on subjective judgments.
Some things can’t be sciences by their very nature.
Maybe that’s too bad, but it is the universe we have.
