What are the underlying causes of psychosis? Why do certain members of the general population experience hallucinations but remain functional while other members enter the psychosis prodrome, and still others go on to experience full-fledged psychosis? In this chapter we will review the putative risk factors associated with psychosis and explore current theories on the pathogenesis of psychosis. We begin with a brief history of psychosis that reviews schizophrenia and related psychosis disorders. Next, we explore genetic risk factors and environmental exposures for psychosis. We conclude this chapter with an overview of current theories regarding the pathophysiology of psychosis and early predictors of psychosis.
