Addiction poses significant social, health, and criminal issues. Its moderate heritability early-life impact, affecting reproductive success, an evolutionary paradox: why are humans predisposed to addictive behaviours? This paper reviews biological psychological mechanisms of substance behavioural addictions, exploring explanations for the origin function relevant systems. Ancestrally, addiction-related systems promoted fitness through reward-seeking, possibly self-medication. Today, psychoactive substances disrupt these systems, leading individuals neglect essential life goals immediate satisfaction. Behavioural addictions (e.g. video games, social media) often emulate ancestrally beneficial behaviours, making them appealing yet irrelevant contemporary success. Evolutionary insights have implications how addiction is criminalised stigmatised, propose novel avenues interventions, anticipate new sources from emerging technologies such as AI. The potential glucagon-like peptide 1 (GLP-1) agonists targeting obesity suggest satiation system may be a natural counter overactivation reward system.

Specifically, we examine how disruptions these socio-cognitive capacities interact with multidimensional to influence self-fragmentation, emotional instability social detachment. Study variables were measured using self-report scales. A two-wave cohort design was implemented a 9-month assessment interval.

Psychotic symptoms are among the most debilitating and challenging presentations of severe psychiatric diseases, such as schizophrenia, schizoaffective, bipolar disorder. A pathophysiological understanding intrinsic brain activity underlying psychosis is crucial to improve diagnosis treatment. While a potential continuum along psychotic spectrum has been recently described in neuroimaging studies, especially for what concerns absolute relative amplitude low-frequency fluctuations (ALFF fALFF), these efforts have given heterogeneous results. transdiagnostic meta-analysis ALFF/fALFF patients with compared healthy controls currently lacking.

Creative behavior has been associated with psychopathological traits, particularly in the psychotic spectrum. Aberrant salience, a transdiagnostic feature of psychosis vulnerability, may influence creative process. This study aimed to investigate differences between artists and non-artists aberrant creativity, personality psychopathology. The sample consisted 123 adults (58 artists, 65 controls) who completed self-report measures, including Salience Inventory (ASI), Big Five (BFI), Obsessive Beliefs Questionnaire (OBS), Remote Associates Test (RAT), Anagram Task (ANAG). Statistical analyses included Mann-Whitney U tests for group comparisons, Spearman correlations, regression analyses. Artists showed significantly higher openness experience, obsessive beliefs, lower scores on RAT ANAG compared controls. Regression revealed that ASI were predicted by greater Openness Conscientiousness religiosity. These findings suggest have propensity altered salience experiences, which contribute their endeavors. strong association experience indicates traits expression vulnerability. Religiosity's role predicting highlights impact cultural spiritual beliefs perceptual experiences. By identifying these associations, this contributes evaluating risk populations psychosis. exhibiting high represent subgroup heightened underscoring importance early detection intervention strategies within communities.

ABSTRACT Prior studies suggest a multifaceted relationship between creativity and psychopathology, indicating that mild psychopathology might enhance creative behavior. Moreover, similar brain regions may be implicated in both psychosis. Although aberrant salience (AS) is often associated with psychotic disorders, it could also capabilities. This study assesses alterations among healthy individuals, artists, patients psychosis to investigate its influence on creativity. Three groups were studied: 196 controls, 50 artists from Florence Academy of Fine Arts, 84 outpatients diagnosis They assessed the Aberrant Salience Inventory (ASI). We compared ASI scores using ANOVA, followed by post‐hoc t ‐tests, adjusted for age, gender, education through ANCOVA. The ANOVA revealed significant differences groups, displaying notably higher than controls patients. ANCOVA confirmed group membership was factor influencing scores, while not. Additionally, antipsychotic treatment did not significantly impact Rather an unequivocal marker pathology, AS interpreted as anthropological asset, enhancing faculties alongside unique perceptual experiences.
