Molecular Neuroimaging, Pathophysiological Mechanisms, and Drug Discovery



This chapter aims to review recent neuroimaging studies that have investigated the relationship between neurochemical dysfunction in psychosis and alterations in regional brain structure and function. It will focus on studies in subjects with an at-risk mental state (ARMS), who have a very high risk of developing psychosis within 1–2 years (Yung et al. 1998). Research in this population provides a powerful means of investigating the mechanisms underlying the onset of psychosis, as the same individuals can be studied before and after the onset of illness. Moreover, as most of the subjects are medication naïve, the results are not confounded by the effects of antipsychotic treatment.
