Abstract

The article discusses contributing factors in the pathogenesis of schizophrenia. In the last fifteen years, the emphasis has shifted from curative to prodromal and premorbid characteristics of later schizophrenia patients. Nevertheless, most studies are limited to the area of early detection and intervention of schizophrenia with much fewer focusing on actual prevention. A more general preventive approach not limited to psychotic condition is clearly underestimated. Following a review of current literature on prodromal approaches and identified premorbid markers of schizophrenia, the article outlines a possible trajectory of later psychotic condition with detectable, distinct stages from birth on. Based on this extended staging model involving neurotoxic impact and early prefrontal-limbic dysfunction, it argues for a refined, phase-specific treatment protocol including preventive interventions. Accepting a model of schizophrenia as an illness with detectable, phase-specific signs and symptoms from infancy on leads to the need to implement preventive interventions. Through this approach, we could, in the optimal case, be able to identify early signs of neuromotoric and cognitive dysfunction not specific for psychosis. Furthermore, it would be useful to lay greater emphasis on the detection of these early signs in the training of health care professionals. This approach calls for a close cooperation between psychologists, psychiatrists, neuropsychologists and special education experts and a change in the way we view psychotic illness.
