Are all psychological problems only biochemical in nature or do some 'mental' components ( that is some form of conceptual 'conditioning' caused directly or indirectly or 'subconsciously' by the person involved), does this effect the development of an 'abnormal' behavioral pattern. If the 'mind-brain' is really just a 'biochemical' behavioral algorithm management mechanism then this would imply all 'mental' disorders are just biochemical mismanagement problems. So are all psychological problems only biochemical problems?
