Obsessive-compulsive disorder (OCD) is a chronic and debilitating psychiatric condition characterized by persistent, intrusive thoughts (obsessions) and repetitive ritualistic behaviors (compulsions). Accumulating evidence suggests that individuals with OCD demonstrate marked cognitive impairments, especially in executive function domains, including cognitive flexibility and working memory. Although existing therapeutic approaches (e.

Under aversive conditions, KO mice exhibited TTM-like behavioral phenotypes compared to wild-type (WT) controls: elevated anxiety-like behavior (reduced total distance 33328.45 ± 6703.

Subjects were cognitively assessed using The MATRICS Consensus Cognitive Battery (MCCB) scales.

Objective: Vitamin B12 is crucial for neurological functions and linked to various psychiatric disorders. Given its importance, this study explores the impact of vitamin B12 deficiency on sleep quality in Obsessive-Compulsive Disorder (OCD) patients, while also examining folate and homocysteine levels to explore their potential interactions with OCD symptoms and sleep quality.
Methods: This cross-sectional study included 52 patients with OCD and 42 healthy controls.
Obsessive-compulsive disorder (OCD) is characterized by intrusive thoughts and repetitive, compulsive behaviors, with childhood trauma recognized as a contributing factor to its pathophysiology. This study aimed to delineate brain functional aberrations in OCD patients and explore the association between these abnormalities and childhood trauma, to gain insights into the neural underpinnings of OCD. Forty-eight drug-naive OCD patients and forty-two healthy controls (HC) underwent resting-state functional magnetic resonance imaging and clinical assessments, including the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and Childhood Trauma Questionnaire-Short Form (CTQ-SF).

Objective: We aimed to predict the possible mechanism of obsessive-compulsive disorder (OCD) by integrating and analyzing mRNA sequencing results from two datasets and to provide direction for future studies into the pathogenesis of OCD.
Methods: Two OCD datasets, GSE78104 and GSE60190, were obtained, and the intersection of the two gene sets with differential expression in OCD samples was selected. Kyoto Encyclopedia of Genes and Genomes (KEGG) signal pathway enrichment and Gene Ontology (GO) analyses were performed using the Database for Annotation, Visualization, and Integrated Discovery (DAVID) online analysis website for the genes at the intersection, and the data were mapped using http://www.
Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder, and cognitive flexibility is a sub-component of executive functioning. Studies have shown impairments in cognitive flexibility in ADHD, which is affected by attentional processes. Personality, as a long-standing trait, has a profound effect on ADHD.

Few studies have explored the relationship between latent profiles of adolescent depression-anxiety symptoms and executive function (EF), which is also a major pediatric public health concern.
Methods: The sample included 1,306 participants who were recruited from two schools in Ningxia.

Objective: Red raspberry serves as a proven natural product to produce anti-inflammatory, antioxidant, and anticancer functions, but limited findings are available on its effects on depression. This study, by using a chronic unpredictable mild stress- (CUMS-) induced depression model, thus investigated the effects and underlying mechanism of red raspberry extract (RRE) on depressive behavior, inflammation, and oxidative stress.
Methods: Different treatments were given after random grouping of Sprague-Dawley rats, including no intervention (control), CUMS induction, and CUMS+different concentrations of RRE, and subsequently, depression-like behavior tests were performed.
Background: Selective serotonin reuptake inhibitors (SSRIs) are the first-line pharmacotherapy for obsessive-compulsive disorder (OCD), but a large proportion of patients do not achieve remission after an adequate SSRI trial. To the best of our knowledge, there have been no well-powered randomized controlled trials (RCTs) of sequenced pharmacotherapy using pragmatic research designs. China provides a unique context for undertaking such a trial that will recruit the largest treatment-naïve participants and systematically compare the efficacy of different sequenced pharmacotherapy.

Facial morphology is one of the most consistent anatomical phenotypes of neurodevelopmental disorders, which can reflect brain structure and function. Facial deformity, an easily measured index of brain malformation, can reflect abnormal brain structure and function.

This study compared the prevalence of behavioral problems among migrant adolescents to those among host adolescents (adolescents from the northern areas) and adolescents in the region of origin (adolescents from the southern areas), to determine whether ecological migration is related to adolescent behavioral problems, and possible changes in such problems over time.
Methods: We used the Children and Adolescents Ecological Migration Survey on Mental Health, administered to 4805 students aged 12-16 years and their parents between 2012 and 2014 (W1), of whom 1753 students and their parents completed the follow-up between 2014 and 2017 (W2).
Objectives: To develop and verify the Psychosomatic Symptom Scale (PSSS) among psychosomatic patients and the cut-off value of PSSS in distinguishing psychosomatic patients from health controls.
Methods: The PSSS was drafted by an expert workgroup. 996 patients and 366 controls from 14 general hospitals in China were recruited to complete PSSS, Patient Health Questionnaire-15 (PHQ-15) and Symptom Checklist-90 (SCL-90).

Objective: To investigate the detection rate and correlates of behavioral problems among eco-migrant children in Hui and Han ethnicities.
Methods: Using multistage randomized sampling method, 2 653 eco-migrant teenagers, 3 174 indigenous and 2 334 homeland peers were selected. Their parents were asked to finish the Achenbach's Child Behavior Checklist (CBCL) and a self-developed correlates questionnaire.
Self-determination theory proposes that prioritizing intrinsic life goals, such as community involvement, is related to well-being, whereas focusing on extrinsic life goals, such as financial success, is associated with lower well-being and that parenting influences the type of life goals that youth adopt. In a sample of 515 Chinese (56% female, mean age = 15.50) and 567 North American (52% male, mean age = 14.

Self-determination theory posits that satisfaction of three basic psychological needs-autonomy, competence, and relatedness-are required for psychological well-being, and a recent study showed that the balance in the satisfaction of these three needs independently affects well-being. The present investigation builds on these findings by examining the balance of adolescents' need satisfaction across distinct life contexts. The results of three studies show that adolescents who experience a balance of need satisfaction across important life contexts, including at school, at home, with friends, and in part-time jobs, reported higher well-being and better school adjustment.

We investigated the construct validity and prediction of DEQ in a Chinese sample, and explored whether Blatt's conceptualizations of depression-prone personality variables are appropriate for the Chinese context.
Methods: The original version of the DEQ was translated into Chinese (DEQ-C).
