Abstract Current knowledge about functional connectivity in obsessive-compulsive disorder (OCD) is based on small-scale studies, limiting the generalizability of results. Moreover, majority studies have focused only predefined regions or networks rather than throughout entire brain. Here, we investigated differences resting-state between OCD patients and healthy controls (HC) using mega-analysis data from 1024 1028 HC 28 independent samples ENIGMA-OCD consortium. We assessed group...
Increased delay discounting is associated with obesity and binge eating disorder (BED). Although BED frequently co-occur, the neural mechanisms underlying in these conditions remain poorly understood.
Introduction: We compared effective connectivity from the locus coeruleus (LC) during resting-state in patients with late-life Major Depressive Disorder (MDD), individuals amnestic Mild Cognitive Impairment (aMCI), and Healthy Controls (HCs). Participants: 23 MDD, 22 aMCI, 28 HCs. Material methods: Participants were assessed two time-points, 2 years apart. They underwent a functional magnetic resonance imaging high-resolution anatomical acquisition, as well clinical assessments. Functional...
Altered activity in decision-making neural circuitry may underlie the maladaptive food choices found obesity. Here, we aimed to identify brain regions purportedly underpinning risk-taking behavior individuals with Twenty-three adult women obesity and twenty-three healthy weight controls completed Risky Gains Task during functional magnetic resonance imaging (fMRI). This task allows participants choose between a safe option for small, guaranteed monetary reward risky options larger rewards....
Anorexia nervosa (AN) is a severe psychiatric disorder characterized by harmful persistence of self-imposed starvation resulting in significant weight loss. Research suggests that alterations the nucleus accumbens (NAcc) and circulating endocannabinoids (eCBs), such as anandamide (AEA) 2-arachidonoylglycerol (2-AG), may contribute to increased severity maladaptive behaviors AN, warranting an examination interplay between central reward circuitry eCBs. For this purpose, we assessed NAcc...
Trait anxiety is a well-established risk factor for and depressive disorders, yet its neural correlates are not clearly understood. In this study, we investigated the of trait in large sample (n = 179) individuals who completed state versions State-Trait Anxiety Inventory underwent resting-state functional magnetic resonance imaging. We used independent component analysis to characterize individual networks (RSNs), multiple regression analyses assess relationship between intrinsic...
Abstract Research on anxiety faces challenges due to the wide range of symptoms, making it difficult determine if different aspects are linked distinct neurobiological processes. Both alterations in functional brain connectivity (FC) and monoaminergic neurotransmitter systems implicated as potential neural bases anxiety. We aimed investigate whole-brain FC involving nuclei its association with dimensions 178 non-clinical participants. Nine anxiety-related scales were used, encompassing trait...
Current methods to assess human anxiety often ignore that is a dynamic process and have limitations such as high recall bias low generalizability real life. Smartphone apps using ecological momentary assessment (EMA) may overcome limitations. We developed smartphone app for the longitudinal evaluation of symptoms EMA. assessed feasibility (retention compliance) psychometric properties (reliability validity) over 6 months in sample 99 participants with different levels anxiety. The EMA-based...
<sec> <title>BACKGROUND</title> Stress is widely acknowledged as a risk factor for various negative health outcomes. Therefore, assessing everyday stress through longitudinal research has gained interest, with focus on capturing and its components using intra-individual approaches ecological momentary assessment (EMA). </sec> <title>OBJECTIVE</title> Building the proposal of Smyth et al. [1], our study aims to investigate relationship between different operationalizations two relevant...
