An interesting article, but it should be pointed out that this is just a theory and not proven fact as of today, as stated in the second paragraph. “A proposed explanation for the development of schizophrenia is that it is a neurochemical disorder”
Their theory is wrong. It is wrong because it assumes the mind (mental) and the brain are the same thing. This would be analogous to saying a computer is only a hardware device and has no software, therefore any malfunction can be fixed by repairing the hardware parts. Of course we know this is not true as we understand computers very well since we designed them. We did not design the human and we don’t as of today understand how it works.
When there is no proven theory, all theories are valid. An equally valid theory is that sz is a disorder of the mind, not the brain and therefore can be overcome by detaching the person’s mind from the hard-coded rules which create the disorder so that they no longer display the conditions which are recognised as sz. Not a popular theory today, but a workable one none the less.
