The etiopathogenesis of schizophrenias

There is no generally accepted model explaining the aetiopathogenesis of schizophrenias. In recent years, hypotheses with a focus on single aspects of neurotransmission, single major genetic loci or single brain areas were predominating. Now, these different approaches converge to systemic models including neurotransmission, genetic changes and neurodevelopmental malformation of brain structures. Such systemic models will explain more aspects of schizophrenias than the recent confined hypotheses.
