Anomalies of imagination and development of psychosis: A phenomenological account.

In 20th century psychiatry, various disturbances of imagination were discussed in the context of schizophrenia. Today, these notions have almost completely vanished from mainstream psychopathology. However, recent work has suggested that specific phenomena within this area have a relevance for differential diagnosis and early detection of psychosis.

Treatment of schizotypal disorder: a protocol for a systematic review of the evidence and recommendations for clinical practice.

Introduction: Schizotypal disorder is associated with a high level of disability at an individual level and high societal costs. However, clinical recommendations for the treatment of schizotypal disorder are scarce and based on limited evidence. This review aims to synthesise the current evidence on treatment for schizotypal disorder making recommendations for clinical practice.

The self, neuroscience and psychosis study: Testing a neurophenomenological model of the onset of psychosis.

Aim: Basic self disturbance is a putative core vulnerability marker of schizophrenia spectrum disorders. The primary aims of the Self, Neuroscience and Psychosis (SNAP) study are to: (1) empirically test a previously described neurophenomenological self-disturbance model of psychosis by examining the relationship between specific clinical, neurocognitive, and neurophysiological variables in UHR patients, and (2) develop a prediction model using these neurophenomenological disturbances for persistence or deterioration of UHR symptoms at 12-month follow-up.

Methods: SNAP is a longitudinal observational study.

Psychiatric comorbidity: a concept in need of a theory.

Despite being a relatively new concept, psychiatric comorbidity, i.e. the co-occurrence of two or more mental disorders, has become widespread in clinical practice and psychiatric research.

Obsessive-compulsive symptoms in the schizophrenia-spectrum: current developments in psychopathology research.

Purpose Of Review: Schizophrenia-spectrum disorders (SSD) frequently involve symptoms that usually are ascribed to nonpsychotic disorder spectra, such as obsessive-compulsive symptoms (OCS). These symptoms can cause differential diagnostic challenges, particularly in early illness stages, and must be considered in treatment planning. In this review, we provide an overview of recent literature within the field of OCS in SSD, with a focus on psychopathology research.

Pseudoneurotic symptoms in the schizophrenia spectrum: An empirical study.

Background: Nonpsychotic symptoms (depression, anxiety, obsessions etc.) are frequent in schizophrenia-spectrum disorders. Twentieth century foundational psychopathological literature claimed that certain nonpsychotic symptoms (here termed pseudoneurotic symptoms) are relatively closely linked with the schizophrenia-spectrum, despite descriptive overlap with symptoms of other diagnoses.

Are Self-disorders in Schizophrenia Expressive of a Unifying Disturbance of Subjectivity: A Factor Analytic Approach.

Background And Hypothesis: The idea that a disorder of the basic self is a central feature in schizophrenia has recently been corroborated in a meta-analysis and a systematic review. Manifestations of the self-disorder can be systematically explored with the Examination of Anomalous Self-Experience (EASE). In this study, we examined the factorial structure of EASE, and diagnostic efficacy of EASE.

What is obsession? Differentiating obsessive-compulsive disorder and the schizophrenia spectrum.

Obsessive-compulsive symptoms are frequent in schizophrenia-spectrum disorders and often cause differential diagnostic challenges, especially in first-contact patients. Drawing upon phenomenology of cognition, we critically review classic and contemporary psychopathological notions of obsessive-compulsive phenomena and discuss their relevance for differential diagnosis between obsessive-compulsive disorder (OCD) and schizophrenia-spectrum disorders. The classic psychopathological literature defines true obsession as intrusions with intact resistance and insight and regards these features as essential to the diagnosis of OCD.

Anomalies of Imagination, Self-Disorders, and Schizophrenia Spectrum Psychopathology: A Network Analysis.

Background: Anomalies of imagination encompass disturbances of the basic experiential structure of fantasies and imagery that can be explored in a semi-structured way with the Examination of Anomalous Fantasy and Imagination (EAFI). We aimed (1) to examine the distribution of anomalies of imagination among different diagnostic groups and a group of healthy controls, and (2) to examine their relation with disorders of basic self, perceptual disturbances and canonical state psychopathology of the schizophrenia-spectrum (positive, negative and general symptoms).

Methods: The 81 participants included patients with schizophrenia or other non-affective psychosis ( = 32), schizotypal personality disorder ( = 15) or other mental illness ( = 16) and healthy controls ( = 18).

Disordered Selfhood in Schizophrenia and the Examination of Anomalous Self-Experience: Accumulated Evidence and Experience.

Disordered selfhood in schizophrenia was rediscovered at the turn of the millennium. In 2005, Psychopathology published the psychometric instrument, the Examination of Anomalous Self-Experience (EASE). In this article, we summarize the historical background of the creation of the EASE, explicate the notion of the disorder of basic or minimal self with the help of phenomenological philosophy, and provide a brief description of clinical manifestations targeted by the EASE.

Schizophrenia-spectrum psychopathology in obsessive-compulsive disorder: an empirical study.

The differential diagnosis of obsessive-compulsive disorder (OCD) and schizophrenia-spectrum disorders can be difficult. In the current diagnostic criteria, basic concepts such as obsession and delusion overlap. This study examined lifetime schizophrenia-spectrum psychopathology, including subtle schizotypal symptomatology and subjective anomalies such as self-disorders, in a sample diagnosed with OCD in a specialized setting.

A Phenomenological Approach to Psychopathology of Imagination: Development of a Descriptive Instrument - Examination of Anomalous Fantasy and Imagination.

This paper serves as an introduction to the Examination of Anomalous Fantasy and Imagination (EAFI) - a novel instrument for a semistructured, phenomenological exploration of psychopathology of imagination. We present an account of the phenomenology of imagination and proceed to a presentation of the disorders of imagination that are addressed in the EAFI. Furthermore, the interrater reliability of the EAFI was examined in a diagnostically heterogeneous sample of 20 in-patients.

EAFI: Examination of Anomalous Fantasy and Imagination.

The Examination of Anomalous Fantasy and Imagination (EAFI) is an instrument for a semistructured, phenomenological exploration of psychopathology of imagination. The EAFI provides a conceptual-descriptive framework to address such experiences. It consists of 16 main items, sometimes divided into subtypes.

Anomalies of Imagination and Disordered Self in Schizophrenia Spectrum Disorders.

Vivid mental imagery occurs frequently in schizophrenia spectrum disorders (SSDs). Overlapping phenomena, such as obsessions or ruminations, are also frequent in other psychiatric disorders, raising significant diagnostic challenges. Unfortunately, contemporary operational psychopathology lacks the epistemological and phenomenological framework to address such questions.

The intestinotrophic peptide, GLP-2, counteracts the gastrointestinal atrophy in mice induced by the epidermal growth factor receptor inhibitor, erlotinib, and cisplatin.

Purpose: Erlotinib, an epidermal-growth-factor receptor inhibitor, belongs to a new generation of targeted cancer therapeutics. Gastrointestinal side-effects are common and have been markedly aggravated when erlotinib is combined with cytostatics. We examined the effects of erlotinib alone and combined with the cytostatic, cisplatin, on the gastrointestinal tract and examined whether glucagon-like peptide-2 (GLP-2), an intestinal hormone with potent intestinotrophic properties, might counteract the possible damaging effects of the treatments.
