The Initial Prodrome in Psychosis: Descriptive and Qualitative Aspects
Open accessAbstract
Objective: This study aimed to describe in detail, using a retrospective approach, the prodromal symptoms in first-episode psychosis patients. This initial prodrome, the period of disturbance preceding a first psychotic episode, is potentially important for early intervention, identification of biological markers, and understanding the process of becoming psychotic. Method: A consecutive series of 21 first-episode patients was recruited from the Early Psychosis Prevention and Intervention Centre, a specialised service for young people aged between 16 and 30 with first-episode psychosis. Subjects were interviewed in the recovery phase after the acute episode, about the period leading up to the psychosis, using a combination of unstructured and semi-structured techniques. Results: A wide variability of phenomena and sequence patterns was found, with symptoms being a mixture of attenuated psychotic symptoms, neurotic and mood-related symptoms, and behavioural changes. Symptoms were often disabling and some, such as suicidal thoughts, potentially life-threatening. Conclusions: The findings highlight the loss of information that has resulted from disregarding early phenomenological studies of the psychotic prodrome and instead focussing on behavioural features. The ground work has been laid for the development of better methodologies for assessing and measuring first psychotic prodromes with increased emphasis on experiential phenomena. This has the potential to lead to the early recognition and more accurate prediction of subsequent psychosis, as well as a deeper understanding of the neurobiology of the onset of psychotic disorder.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
