Phenomenology, clinical aspects and therapeutic implications of delusional memories in Delusional Disorders: A Systematic Review
Bibliographic record
Abstract
INTRODUCTION: Delusional memories or retrospective delusions have been extensively reported in subjects during or after intensive care stays. In major psychoses, authors have classically observed delusional memories impacting the prognosis and mental well-being. OBJECTIVES: Our aim was to review the phenomenology, psychological/biological factors contributing to delusional memories in delusional disorder (DD), and potential treatment strategies. METHODS: Systematic review using PubMed, Scopus, SciELO and Web of Science electronic databases (inception-September 2022). Search terms: (“delusional memories” OR “retrospective delusions”) AND (“Schizophrenia, Paranoid”) [MeSH]. Studies were included if they reported psychopathology, clinical characteristics or treatment strategies of “delusional memories” in DD. Team members: AGR, JAM, MS, MB, MF, ACP, FD, MVS. RESULTS: A total of 786 records were retrieved, including six studies. Psychogenesis:A novel cognitive neuropsychological research model (based on hypnosis) in erotomania delusions suggest a potential recall and reinterpretation of delusions beliefs in highly hypnotizable subjects. Biological basis: Frontal lobe (or executive) dysfunction does not seem to contribute to delusional memories in De Clérambault syndrome (erotomania). Phenomenology: 1)General knowledge was essentially intact, while the perceptual characteristics of delusional memories were stronger than real memories. 2)Correlations were found between delusional ideation, positive dimension of schizotypy (r=0.18), and false memories (r=0.27). 3)Jumping-to-conclusions and liberal acceptance bias influence delusional memories. Treatment:Efficacy of 1)Cognitive Behavioural Therapy (CBT) (significant reduction delusions), and 2)Metacognitive control over false memories. CONCLUSIONS: This is the first review exploring the genesis and management of delusional memories in DD. Memory deficits/executive dysfunctions do not seem to be the only cause of this phenomenon.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
