Just weeks before the long-awaited publication of a new edition of the so-called bible of mental disorders, the federal government’s most prominent psychiatric expert has said the book suffers from a scientific “lack of validity”.
The expert, Dr. Thomas R. Insel, director of the National Institute of Mental Health, said in an interview Monday that his goal was to reshape the direction of psychiatric research to focus on biology,genetics and neuroscience so that scientists can define disorders by their causes, rather than their symptoms.
While the Diagnostic and Statistical Manual of Mental Disorders, or D.S.M., is the best tool now available for clinicians treating patients and should not be tossed out, he said, it does not reflect the complexity of many disorders, and its way of categorizing mental illnesses should not guide research. 
Biology and neurology are already outside of the correct path: they constantly look for “causes” based on the dogma of materialism, completely forgetting (?) that we are also sould and spirit.
See for example some research article titles of brain research from Nature:
Brain mechanisms of altered conscious states during epileptic seizures
Andrea Eugenio Cavanna & Francesco Monaco
Nature Reviews Neurology 5, 267-276 doi:10.1038/nrneurol.2009.38
Multisensory brain mechanisms of bodily self-consciousness
Nature Reviews Neuroscience 13, 556-571 doi:10.1038/nrn3292
Neural correlates of consciousness in humans
Geraint Rees, Gabriel Kreiman & Christof Koch
Nature Reviews Neuroscience 3, 261-270 doi:10.1038/nrn783
Neuroscience: The mind mapped
Nature 483, 271-272 doi:10.1038/483271a
See how “the brain is what generates consciousness and everything” is the foundation of all research? See how all there “is” are neurons, chemistry and matter. No room for anything else there.
Now imagine these sciences crisizing another science of being dogmatic!
We are getting closer to biology-based diagnoses.  When the blood test says so, you will be tagged “crazy”. No matter what you may think!
PS. And YES, psychiatry is way out of order. It has the tendency to name everything “mental disease”… Read The dictatorship of the science of psychiatry for more on that.
