“…The finding that PEs and DE are related to one another is in agreement with prior research (Aragona et al, 2015; Hugo & Lacey, 1998; Miotto et al, 2010), and is an important contribution to the existing literature as the body of evidence is relatively scarce (Pereira et al, 2016). The relationship between psychosis and EDs has first been reported cross-sectionally in clinical studies, with findings indicating either eating-related symptoms in psychotic disorders (Ferguson & Damluji, 1988; Kouidrat et al, 2014; Yum et al, 2009), or psychotic features in EDs (Brodrick et al, 2020; Rojo-Moreno et al, 2011). Previous studies also pointed to possible longitudinal links in both directions, with EDs as a prodrome preceding full-blown psychotic disorders (Kelly et al, 2004; Malaspina et al, 2019), or psychotic experiences preceding DE (Solmi et al, 2018).…”

Background: The relationship between psychosis and disordered eating remains a challenging area of research to which little interest was paid. Using longitudinal data, we aimed to explore the hypothesis that the pathways from psychotic experiences (PEs) to disordered eating (DE) and body-mass index (BMI) are mediated by body-image disturbances. Methods: A prospective longitudinal study was performed. High-school students ( N = 510, 61.2% females, mean age of 16.05 ± 1.01 years) were asked to complete three scheduled assessments (Baseline, 6 months, and 12 months). Results: Two body image components, that is, Overweight Preoccupation and Body Area Satisfaction, mediated the prospective association between baseline PEs and DE 12 months later. Direct effects were significant. After accounting for indirect effects through more severe body image concerns at 6 months, higher baseline PEs were significantly associated with greater DE at 12 months. Baseline PEs and 6-month body image explained a significant proportion of variance in 12-month DE. However, we did not find evidence of a direct prospective association between PEs and BMI. Conclusion: This study is the first to assess the mediating role of body image between PEs and DE. Findings offer promising new avenues for early intervention to help mitigate the effects of PEs on DE in adolescents.

“…4 Despite the commonly held belief that the presence of body image distortion is necessary for diagnosing AN, the patient's persistent poor insight into the severity of weight loss and the seriousness of their condition should be sufficient for diagnosis. 5 In this case report, we have focused on the impact of various factors, especially the psychological aspect of the disorder and the role of the family in managing symptoms and treatment of the disease. 6 The construct of expressed emotion (EE), the needs of the caregivers, and the role of perfectionism in AN will be discussed in this article.…”

“…Plenty of research suggests that malnutrition can contribute to psychosis through various pathways. Specific nutritional deficiencies, sleep deprivation, and metabolic derangements are known medical causes of psychosis [ 3 ]. It can be argued that eating disorders and psychotic disorders are different expressions of the same illness, with distorted thoughts about eating being a form of delusion [ 4 ].…”

Psychosis is a mental disorder in which an individual exhibits a loss of contact with reality; this definition, however, often fails to convey the broadness and complexity behind the diagnosis. While studies agree that it is best practice to address psychosis by treating its underlying cause, manifestations of psychosis do vary widely and may be challenging to identify in some clinical scenarios, such as the one presented here. Binge eating in the setting of psychosis has been observed in instances where alterations of the gut microbiota in response to an eating disorder trigger psychotic episodes. However, instances in which the manifestation of psychosis itself is the catalytic factor for the presentation of a binge-eating event with aggression and delusions are seldom observed in the current medical literature. Of note, many of the drugs used to treat mental illness have been associated with regulating food intake. We aim to further expand on the association between psychosis, eating disorders, and management thereof in the setting of polypharmacy and undesired side effects. Here, we present the case and management of a 71-year-old male Hispanic patient with a significant history of mental illness who was admitted to the hospital due to acute gastroenteritis precipitated by binge eating during a psychotic episode.
