Mechanisms of schizophrenia



The underlying mechanisms of schizophrenia, a mental disorder characterized by a disintegration of the processes of thinking and of emotional responsiveness, are complex. A number of theories attempt to explain the link between altered brain function and schizophrenia, the most important of which are the dopamine hypothesis and the glutamate hypothesis. Note that these theories are separate from the causes of schizophrenia, which deal with actual starting points of the illness instead, e.g. genetic and environmental factors. The current theories attempt to explain how changes in brain functioning can contribute to symptoms of the disease.
