Clinical phenomenology of anomalous subjective experiences: a guide for the perplexed

Presentation First Author: 
Andrea Raballo

Nonpsychotic anomalies of subjective experience have been described as a core feature of schizophrenia both in classical and recent psychopathological literature. Some of these experiential alterations have been demonstrated to antedate the onset of psychosis and possibly shape pre-clinical trajectories towards help-seeking as well as transitions to full-blown psychosis. Among those, two constructs are prominent in contemporary early detection and intervention research: cognitive-perceptual basic symptoms (CPBS) and self-disorders (SDs). Although both CPBS and SDs denote morbid, not-yet psychotic alterations of conscious experience (i.e. subjectivity), CPBS have been mainly operationalized to intercept early prodromal phases of psychosis, whereas SDs primarily define a trait-vulnerability towards schizophrenia spectrum disorders (with or without psychosis). This presentation will offer a clinical-conceptual grasp on nonpsychotic anomalies of subjective experience for the purpose of early differential diagnosis and clinical staging of Ultra-high Risk mental states.
