Abstract

Efforts to prevent or lessen the functional impact of psychosis can be informed by a better understanding of the neurobiological underpinnings at the earliest stages of the disorder. Understanding these processes early in the psychosis spectrum will in turn allow more targeted efforts to prevent or minimize functional limitations among patients with psychosis. Advances in technology have enabled the study of a host of biomarkers implicated in the neurobiology of psychosis offering unique avenues to investigate mechanisms of disease while at the same time shedding some light on more patient-tailored treatments and setting the foundation for personalized medicine in psychosis. Insights into the neurobiology of psychosis are reviewed, including findings from neuroimaging, neurocognitive, and electrophysiologic studies and findings related to the role of hypothalamic-pituitary axis activity and neuroinflammation in the emergence of psychosis. Biomarker-informed treatments are discussed, and potential promising biomarkers and related treatments are proposed. This review contains 5 figures, 13 tables, and 85 references. Key words: attenuated risk syndrome, biomarkers, prodrome, psychosis, schizophrenia, treatment
