Summary
Psychosis refers to the state of having a set of experiences and beliefs that do not accord with accepted reality and that seem to arise and persist in ways that do not reflect the evidence available. It is important to remember that the term is descriptive and is not in itself a diagnosis. Indeed, it emerges across a wide range of psychiatric, neurological and other physical disorders as well, in various forms, as a consequence of stress, trauma, drug use and other perturbations to the nervous system. Moreover, attention has more recently focused on the existence of attenuated psychosis-like thinking distributed within the healthy population: a phenomenon that has long been recognised (Taine, 1871) and that become a focus for systematic study more recently (e.g. van Os et al., 2009).
