Bleuler's Psychopathological Perspective on Schizophrenia Delusions: Towards New Tools in Psychotherapy Treatment

'An experience of meaning': A 20-year prospective analysis of delusional realities in schizophrenia and affective psychoses

Delusions are transdiagnostic and heterogeneous phenomena with varying degrees of intensity, stability, and dimensional attributes where the boundaries between everyday beliefs and delusional beliefs can be experienced as clearly demarcated, fuzzy, or indistinguishable. This highlights the difficulty in defining delusional realities. All individuals in the current study were evaluated at index and at least one of six subsequential follow-ups over 20 years in the Chicago Longitudinal Study. We assessed 16 distinct delusions categorized as thought or thematic delusions. We also examined the probability of recurrence and the relationships between delusions and hallucinations, depression, anxiety, and negative symptoms. The sample consisted of 262 individuals with schizophrenia vs. affective psychosis. Thought delusions were significantly different between groups at all follow-up evaluations except the 20-year timepoint. Thematic delusions were more common than thought delusions and show a significant decreasing pattern. In general, delusional content varied over time. Referential, persecutory, and thought dissemination delusions show the highest probability of recurrence. Hallucinations were the strongest indicator for thought, thematic, and overall delusions. The formation and maintenance of delusions were conceptualized as a multimodal construct consisting of sensory, perceptual, emotional, social, and somatic embodiment of an "experience of meanings". Given the significant associations between delusions and hallucinations, future work incorporating participatory research is needed to better define and align subjective and objective perspectives. Our research also points to the need for future clinical interventions that specifically evaluate and target the coexistence and entanglement of delusions and hallucinations.

The role of psychological autopsy in investigating a case of atypical suicide in schizophrenia: a case report with a brief review of literature

Background

Self-harm typically is without lethal intent. Death can occur rarely, with suicide taking on an atypical form that raises the suspicion of hetero-aggression. Our study aimed to identify the link between self-harm and suicide intent and also to outline the positive diagnosis of an atypical suicide case which has raised the suspicion of hetero-aggression. For this purpose, the psychological autopsy method should be used regularly in suicide investigation because it not only allows a positive diagnosis of suicide but can also provide a detailed picture of mental degradation and associated suicide risk factors.

Case presentation

The case of a 26-year-old man from a rural area, found dead in the basement, at home, naked, barricaded inside, is described.

Methods

The on-site investigation and a complete forensic autopsy were performed. In addition, we apply the psychological autopsy method which gathered enough information to outline the positive diagnosis of suicide. We also made a brief literature review on the suicide risk factors and the behavioral changes that occurred during the COVID-19 pandemic in schizophrenic patients.

Results

The forensic autopsy revealed that he presented a complex craniofacial trauma as the cause of death (with scalp lacerations, frontal fracture, subarachnoid hemorrhage, and frontal cerebral contusions) associated with torso trauma (with self-inflicted stabbed wounds) with bruises and abrasions on the limbs. The injuries that caused death were self-inflicted and ensued repeatedly hitting his head against blunt objects. Using the psychological autopsy method, we found out that he presented multiple psychiatric hospitalizations for schizophrenia for almost 10 years, recently with reduced compliance to treatment. We also documented two previous suicide attempts and a gradual deterioration of his mental health.

Conclusions

We highlighted the role of the psychological autopsy (in addition to the judicial investigation and the forensic autopsy) for the diagnosis of committed suicide, for making a rigorous differential diagnosis between accident, hetero-aggression, and suicide, and also in pin-pointing the suicide risk factors.

Schizophrenia-schizoaffective-bipolar spectra: an epistemological perspective

For decades clinicians and researchers have been thinking and writing about the spectrum of schizophrenia disorders. Indeed both Kraepelin and Bleuler believed in schizophrenia as a spectrum, both in a clinical (individual) and hereditary (family) continuum, from just some exquisite personality traits to unquestionable chronic and debilitating psychosis. Other authors would put the schizophrenia spectrum disorders on different levels of continuum: developmental, psychofunctional, existential, and genetic. Here, we would like to present an historical chronology for the schizophrenia-schizoaffective-bipolar spectra plus a tridimensional model for these spectra: the first axis for categories (affective versus nonaffective psychoses), the second axis for dimensions (personality versus full blown psychosis), and a third axis for biomarkers (remission versus relapse). We believe that without the schizophrenia-schizoaffective-bipolar spectra concept in our minds all our efforts will keep failing one the hardest quest: searching for biomarkers in schizophrenia and related disorders.
