Abstract Coffee is the most widely consumed source of caffeine worldwide, partly due to psychoactive effects this methylxanthine. Interestingly, its chronic consumption on brain’s intrinsic functional networks are still largely unknown. This study provides first extended characterization coffee human brain networks. Subjects were recruited and divided into two groups: habitual drinkers (CD) non-coffee (NCD). Resting-state magnetic resonance imaging (fMRI) was acquired in these volunteers who...
White matter pathways, typically studied with diffusion tensor imaging (DTI), have been implicated in the neurobiology of obsessive-compulsive disorder (OCD). However, due to limited sample sizes and predominance single-site studies, generalizability OCD classification based on white estimates remains unclear. Here, we tested accuracy using largest DTI dataset date, involving 1336 adult participants (690 patients 646 healthy controls) 317 pediatric (175 142 from 18 international sites within...
Obsessive-compulsive disorder (OCD) is associated with emotion regulation impairments, namely the frequent use of maladaptive strategies such as suppression and decreased reappraisal strategies. Additionally, these patients exhibit elevated stress levels. Since exposure affects abilities, might influence relationship between obsessive-compulsive symptoms regulation. In this study, we explored effects on in a sample healthy OCD individuals. We used self-reported psychometric scales to measure...
Habitual coffee consumers justify their life choices by arguing that they become more alert and increase motor cognitive performance efficiency; however, these subjective impressions still do not have a neurobiological correlation. Using functional connectivity approaches to study resting-state fMRI data in group of habitual drinkers, we herein show consumption decreased the posterior default mode network (DMN) between somatosensory/motor networks prefrontal cortex, while nodes higher visual...
The COVID-19 outbreak has imposed physical and psychological pressure on health care professionals, including frontline physicians. Hence, evaluating the mental status of physicians during current pandemic is important to define future preventive guidelines among stakeholders.
Introduction The COVID-19 outbreak and the community mitigation strategies implemented to reduce new SARS-CoV-2 infections can be regarded as powerful stressors with negative consequences on people's mental health. Although it has been shown that emotional symptoms subside during lockdown, is likely existence of inter-individual differences in stress, anxiety depression trajectories throughout lockdown. Objectives We aimed cluster participants' according their scores identify...

However, due to limited sample sizes and predominance single-site studies, generalizability OCD classification based on white estimates remains unclear.

Introduction: The Obsessive-Compulsive Inventory-Revised has been developed to evaluate the severity of obsessive-compulsive symptoms in both clinical and non-clinical individuals. aim this study was psychometric properties Portuguese version.Material Methods: This questionnaire applied 90 people with disorder 246 without a known mental illness. In addition evaluation instrument, participants completed other assessment scales that helped characterize two groups.Results: Given objective...
Symptom provocation paradigms are paramount to understand a heterogeneous disorder as obsessive-compulsive (OCD). The main aim of our work was develop and validate an open-access set OCD-related images comprising three subtypes: washing, checking, symmetry. Twenty-six OCD patients 25 controls provided valence arousal ratings for OCD-related, aversive, neutral images. Linear mixed model analyses were used estimate the effects group, image category, group-image category interaction in ratings....
There is a large variety of context-related aspects that shape our decisions. One such aspect related with the emotional state. Previous studies have suggested arousal has role on modulation risk-taking behavior in gambling tasks. In this study, we aimed to test hypothesis. For purpose, developed an experimental apparatus, which presented highly arousing stimuli opposing hedonic valences as strategy for inducting Individuals performed risky decision-making task, they accumulate gains each...
