Research on causes for schizophrenia: are we close?
Schizophrenia is assumed to be a complex multifactorial disorder with several environmental and genetic factors contributing to its development. The disorder is unique in terms of the expression of symptoms, which are related to the exclusive ability of humans to think and communicate these thoughts to the members of their species. Therefore, no potent animal-, or cell models are available in order to validate existing hypotheses. In contrast to other disorders with similar complex etiology, but availability of model organisms, i.e. diabetes type II, age-related macular degeneration or Alzheimer’s disease, pathogenesis of schizophrenia is still unknown, despite a considerable amount of research.
