AI Article Synopsis

  • Delusions are primarily recognized as a positive symptom of schizophrenia but can also occur in various other mental and neurological disorders.
  • The complexity of delusions, combined with the absence of suitable animal models, makes it challenging to study them in isolation.
  • This text proposes that the claustrum, a less-explored structure in the brain, may serve as a central hub for understanding delusional states, backed by existing research findings.

Article Abstract

Delusions are a hallmark positive symptom of schizophrenia, although they are also associated with a wide variety of other psychiatric and neurological disorders. The heterogeneity of clinical presentation and underlying disease, along with a lack of experimental animal models, make delusions exceptionally difficult to study in isolation, either in schizophrenia or other diseases. To date, no detailed studies have focused specifically on the neural mechanisms of delusion, although some studies have reported characteristic activation of specific brain areas or networks associated with them. Here, we present a novel hypothesis and extant supporting evidence implicating the claustrum, a relatively poorly understood forebrain nucleus, as a potential common center for delusional states.

In 1994, the DSM-IV added the specifier "with poor insight" to the diagnostic criteria of obsessive-compulsive disorder (OCD). The DSM-5 went one step further and now allows clinicians to diagnose OCD "with absent insight/delusional beliefs," thereby blurring the long-standing distinction between OCD and psychosis. The present study surveyed OCD experts as to their opinions on the insight specifier and the future classification of OCD.

The degree to which numerous existing models of delusion formation disagree or propose common mechanisms remains unclear. To achieve a comprehensive understanding of delusion aetiology, we summarised 53 theoretical models of delusions extracted from a systematic literature search. We identified central aspects and unique or overarching features of five core perspectives: cognitive (n = 22), associative learning (n = 4), social (n = 6), neurobiological (n = 6), and Bayesian inference (n = 15).

Hallucinations and delusions can be symptoms of psychiatric illness, but more often—though less commonly known—are actually part of a healthy range of experiences found throughout the general population. The studies in this Special Collection paint a picture of the wide range of hallucinatory and delusional experiences across diverse populations, as well as comparative perspectives between clinical and non-clinical samples. In this editorial, I make three related points that are exemplified in the articles published here.

Aim: This study explores the intricate relationship between social interactions and the development of persecutory delusions among older women living alone in Japan. Focusing on the unique perspective of individuals experiencing delusions outside clinical settings, the aim was to understand the impact of interpersonal interactions on delusion formation.

Methods: Cases of older women living alone with persecutory delusions were selected from records of municipal psychogeriatric services and medical consultations within a community space.
