Abstract
Summary: The dopamine hypothesis has been the major pathophysiological theory of psychosis in recent decades. Molecular imaging studies have providedin vivoevidence of increased dopamine synaptic availability and increased presynaptic dopamine synthesis in the striata of people with psychotic illnesses. These studies support the predictions of the dopamine hypothesis, but it remains to be determined whether dopaminergic abnormalities pre-date or are secondary to the development of psychosis. We selectively review the molecular imaging studies of the striatal dopaminergic system in psychosis and link this to models of psychosis and the functional subdivisions of the striatum to make predictions for the dopaminergic system in the prodromal phase of psychosisThis publication has 78 references indexed in Scilit:
