As inflammation is implicated in mental illness, we investigated adherence to the Mediterranean diet (MD), an anti-inflammatory diet, and the standard American diet (SAD), and examined cross-sectional relationships with psychiatric symptoms and cognition. Method: Participants included 54 individuals with psychotic disorders, 30 with non-psychosis affective disorders and 40 healthy controls. Participants underwent diagnostic interviews, PANSS symptom ratings, and MATRICS cognitive assessments. The self-report GBAQ was used to assess adherence to the MD versus SAD. Results: The psychosis group was significantly more likely to consume the SAD than healthy controls (p = 0.007), with MD adherence predicting better working memory (r = 0.461, p < 0.001). In the non-psychosis affective disorders group, MD adherence predicted slower processing speed (r = -0.376, p = 0.049). In the non-psychosis affective disorders group, MD predicted reduced PANSS General Psychopathology scale (r = -0.449, p = 0.013), as well as the Activation (r = -0.362, p = 0.049), and Dysphoric Mood factors (r = -0.403, p = 0.027).Discussion: This first-of-its kind study identified poor dietary choices in persons with psychosis, showing significantly lower symptoms and better cognition in association with the MD in transdiagnostic analyses.

In the current study, we examined whether the positivity offset is relevant to explaining anhedonia and liability for psychosis among individuals at clinical high-risk for psychosis (CHR) (i.e., individuals exhibiting attenuated hallucinations or delusions that cause distress and functional decline). Mathematical modeling approaches from Cacioppo’s Evaluative Space Model were applied to six days of digital phenotyping data collected in daily life among 100 individuals at CHR and 57 healthy controls (CN). Participants reported levels of positive emotion, negative emotion, and arousal throughout the day via ecological momentary assessment (EMA) surveys while accelerometry was passively recorded. EMA surveys were used to calculate the positivity offset and examine associations with real-world motivated behavior. Results indicated that the positivity offset was present among individuals at CHR, but diminished compared to CN. Importantly, smaller positivity offset scores were associated with greater clinically rated anhedonia, particularly among CHR cases with comorbid mood disorder diagnoses. Findings suggest that reductions in the positivity offset are a mechanism underlying anhedonia across phases of psychotic illness and represent a novel treatment target that is relevant for the treatment of negative symptoms and prevention of psychotic disorders.</div></div>","PeriodicalId":21417,"journal":{"name":"Schizophrenia Research","volume":"281 ","pages":"Pages 45-51"},"PeriodicalIF":3.6,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The National Library of Medicine database of literature was searched for publications relating to our topic through June 2024. Our results highlight the Mediterranean diet’s potential role in mediating inflammation, potentially through the gut-brain axis, and its neuroprotective role against cognitive decline. Moreover, individual components of the Mediterranean diet are potentially therapeutic as well as protective, particularly fruits, vegetables, fatty fish, and whole grains. These dietary components reduce systemic inflammation, modulate gut microbiota and influence critical pathways such as moderating oxidative stress. Overall, this survey of recent literature highlights the potential of the Mediterranean diet to promote mental health and reduce the risk or severity of psychiatric and neurodegenerative disorders. The analysis underscores broader implications for the Mediterranean diet in advancing mental health outcomes and emphasizes the need for further studies and increased public education to encourage healthier eating habits and dietary interventions.</div></div>","PeriodicalId":21417,"journal":{"name":"Schizophrenia Research","volume":"281 ","pages":"Pages 30-44"},"PeriodicalIF":3.6,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143891629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
