Evidence for an interrelated cluster of Hallucinatory experiences in the general population: an incidence study.

摘要: Background Although hallucinations have been studied in terms of prevalence and its associations with psychopathology functional impairment, very little is known about sensory modalities other than auditory (i.e. haptic, visual olfactory), as well the incidence hallucinations, factors predicting subsequent course. Methods We examined incidence, course risk hallucinatory experiences across different two unique prospective general population cohorts same country using similar methodology three interview waves, one over period 1996-1999 (NEMESIS) 2007-2015 (NEMESIS-2). Results In NEMESIS-2, yearly self-reported was highest (0.33%), followed by haptic (0.31%), (0.26%) olfactory (0.23%). Rates NEMESIS-1 were (respectively: 0.35%, 0.26%, 0.23%, 0.22%). The clinician-confirmed approximately 60% rate. persistence rate incident around 20-30%, increasing to 40-50% for prevalent hallucinations. Incident modality strongly associated occurrence another (median OR = 59) all delusional ideation 21). Modalities equally presence any mental disorder 4), functioning, indicators help-seeking established environmental psychotic disorder. Conclusions Hallucinations are a clinically relevant feature non-psychotic disorders need be relation each ideation, appear common underlying mechanism.
