Summary: Using fiber photometry and optogenetics, the study found that cell-type-specific dysfunctions in the OFC-striatal circuit in an OCD mouse model causally lead to impaired reversal learning, indicating a potential therapeutic target for treating cognitive inflexibility in OCD.

Summary: Studies have found that OCD patients have significantly lower levels of transcripts related to excitatory signaling in both cortical and striatal regions compared to unaffected individuals. While the majority of transcripts encoding excitatory synaptic proteins were lower in OFC, there were no significant differences in the striatum of OCD subjects. These findings suggest a potential upstream causal event in the observed lower levels of multiple glutamatergic transcripts across both medial and lateral OFC.

Summary: Intravenous infusion of ketamine rapidly reduces obsessive-compulsive disorder symptoms. Here, the authors show in mice that ketamine acts by increasing activity in a fronto-striatal circuit that causally controls compulsive grooming behavior.

Summary: This study is the largest to date examining subcortical surface morphometry in OCD. The results show that individuals with OCD exhibit surface expansions on the right nucleus accumbens and inward left amygdala deformations, and these shape alterations are associated with OCD symptom severity. The study also found that these changes are driven by age and health status.

Summary: Gyrification patterns are indicative of early neurodevelopment and may have a strong heritable component. Although findings have been inconsistent, it has been consistently observed that patients with obsessive-compulsive disorder exhibit altered gyrification patterns in the orbitofrontal cortex. However, no studies have yet examined gyrification alterations in unaffected first-degree relatives of these patients.

Summary: This study aims to explore the relationship between cognitive inflexibility and ventrolateral prefronto-basal ganglia-thalamic subnetworks in patients with obsessive-compulsive disorder (OCD). The results reveal that patients have hyperconnected fronto-external pallidal subnetworks in the cortico-basal ganglia-thalamo-cortical network, which may contribute to behavioral inhibition and compensatory mechanisms for impaired set shifting.

Summary: This study aimed to investigate the role of obsessive-compulsive features in different behavioral addictions and explore the existence of empirical clusters based on obsessive-compulsive measures among treatment-seeking patients. Results showed that patients with compulsive sexual behavior disorder and compulsive buying-shopping disorder had higher scores on the obsessive-compulsive subscale, while patients with gambling disorder and internet gaming disorder had lower scores on other dimensions. Two mutually exclusive clusters were identified.

Summary: Inappropriate fear expression and failure of fear extinction are commonly seen in patients with PTSD and OCD. Aberrant and asymmetric activation of the lOFC is reported in some clinical cases. The study found that activation of the lOFC interfered with the in-session expression of conditioned fear and impaired the acquisition of fear extinction. The abnormal activation of the lOFC disrupted the excitatory/inhibitory balance of neuronal activities in fear-related brain regions.

Summary: Several studies have found that OCD, ED, ASD, and BDD share common symptoms and often co-occur, suggesting a common etiological basis. The study found that executive functioning skills such as attention switching and social communication skills were central in individuals with these disorders. Difficulty with cognitive flexibility and social factors are key factors in OC-spectrum disorders.

Summary: People recovered from mild COVID-19 may experience respiratory and neurological issues, as well as cognitive impairment. A study found that approximately one-quarter of mild COVID-19 individuals exhibited a specific visuoconstructive deficit, which correlated with changes in brain imaging and upregulation of immune markers. These findings suggest that neuroinflammation may contribute to cognitive impairment in a significant portion of the population, highlighting the need for comprehensive assessment and rehabilitation.

Summary: Children and adolescents were significantly affected by the psychosocial impact of the 2019-2022 pandemic, leading to increased internalizing symptoms, screen time, and internet addiction. A repeated cross-sectional study was conducted to investigate the relationship between screen time, game addiction, and internalizing symptoms during the COVID-19 pandemic. The results showed a correlation between higher levels of game addiction and higher levels of internalizing symptoms, regardless of screen time. This highlights the need for further research on the relationship between internet addiction and internalizing symptoms, as well as the long-term effects of excessive screen time.

Through two rounds of surveys, experts reached consensus on the targets, approaches, active ingredients, and modes of delivery for these interventions. The study indicates that intervention measures based on validated techniques and flexible delivery methods can effectively improve cognitive deficits in the treatment of substance use disorders.

Summary: The study aimed to evaluate features associated with sleep disturbances in healthcare workers (HCW) during the COVID-19 pandemic. The results showed that sex, previously diagnosed mental illness, and frontline work with COVID-19 were associated with sleep problems. Furthermore, previous diagnosis of mental illness was strongly related to insomnia development. Strategies targeting sleep difficulties in HCWs are advised during the pandemic.

Summary: This paper analyzes the relationship between sociodemographic variables, executive dysfunctions, Sluggish Cognitive Tempo (SCT), and the dimensions of hyperactivity-impulsivity (ADHD-H/I) and inattention (ADHD-IN) in Brazilian adults. The study recruited 446 participants (295 women) aged 18 to 63 years old. Higher scores in ADHD dimensions were associated with more executive functioning problems and time perception distortions. ADHD-IN and SCT were more strongly associated with these dysfunctions than ADHD-H/I. Regression analysis showed that ADHD-IN was related to self-management of time, ADHD-H/I was related to self-restraint, and SCT was related to self-organization and problem-solving.

Through multiple assessments at different time points, two subgroups of healthcare workers with high-PTSS and low-PTSS profiles were identified. Being female, fear of contamination, and fearing financial problems were strong predictors of changes in the profile.

Summary: Mood disorders caused by chemotherapy have become more important as cancer patients' survival increases. This study used methotrexate to induce mood disorders in rats and found that treatment with the antioxidant N-acetylcysteine (NAC) can alleviate anxiety and depression-like behaviors, increase antioxidant capacity, reduce oxidative stress and inflammatory response, and regulate brain chemistry. The findings suggest that NAC treatment could be an effective strategy in revising the treatment for individuals suffering from chemotherapy-induced mood disorders.

This study investigated the relationship between self-esteem, aggression, and brain structure in healthy children, and found that self-esteem was negatively associated with aggression. The study also revealed that increased cortical thickness in certain brain areas may be a potential mechanism linking low self-esteem to aggression in children.

This study used Aplysia as an animal model to investigate the memory deficits caused by prolonged food deprivation. The results showed that 14 days of food deprivation decreased the level of 5-HT in the hemolymph, which contributed to the lack of sensitization and its cellular correlates. However, exogenous application of 5-HT partially induced sensitization in the food deprived animals.
