Summary: This study aimed to evaluate the effect of working memory training on executive functions and behavioral symptoms in children with ADHD. Thirty children with ADHD were randomly assigned to active control or Active Memory Intervention (AMIN) group. Executive functions and rating scales were used for assessment in three baseline, post-intervention, and 1-month follow-up sessions. The results show that AMIN improves working memory and inhibitory control as well as ameliorates ADHD symptoms at home and school. Working memory training is a beneficial and transferable intervention in children with ADHD.

Summary: This study examined the association between screen time and ADHD symptoms using data from approximately 4000 Canadian high school students. The results revealed that increased screen time was associated with worsening ADHD symptoms, with impulsivity being the strongest mediator of this association.

Summary: The CDH13 gene is associated with various neuropsychiatric disorders and influences personality traits, behavior, and executive functions. Limited evidence exists for the functional effects of common gene variation in humans, but it may impact personality traits and neural processing during working memory tasks.

Summary: This study investigated the role and underlying mechanism of the SNAP-25 MnlI variant in cognitive impairment and brain functions in boys with ADHD. The results showed that TT homozygotes had higher WM capacity and ReHo values for the left mPFC compared to G-allele carriers. However, the WM capacity in the G-allele carrier group was negatively correlated with the peak ReHo value for the left mPFC.

Summary: The study examined the feasibility of a new ecological navigation task, VC(TM), to test visuo-spatial memory and executive functions in children with ADHD. Results show that the task is ecologically valid, motivationally engaging, and strongly relies on efficient spatial memory, presenting potential new avenues for intervention.

Summary: Despite the incongruent results in previous studies, our research found that children and adolescents with ADHD who have higher weight demonstrated lower efficiency in inhibition processes and tended to give impulsive and incorrect answers. These impulsive reactions may contribute to the risk of excessive weight in individuals with ADHD.

Summary: This study aimed to investigate the effects of quiet eye training (QET) on inhibitory control, visuospatial working memory (WM), and tonic attention in children with ADHD. The QET group showed significant improvements in the go/no-go inhibition test, with shorter reaction times, a higher number of correct responses, and a lower number of omissions compared to pre-measurements, while the control group did not show significant changes. The measures of WM and tonic attention did not significantly change with the QET-based intervention.

Summary: Psychostimulants have shown to improve certain aspects of cognition in individuals with ADHD, particularly in attention and memory. However, the efficacy of psychostimulants in other cognitive domains remains inconclusive.

Summary: This study aimed to test the effectiveness of two digital therapeutic training protocols (CET and ICT) on improving emotion regulation in children with ADHD. The results showed that both treatments led to significant improvements in emotion dysregulation, and the effects were maintained at follow-up assessments. Surprisingly, there were no significant differences between the CET and ICT groups in terms of reducing emotion dysregulation.

Summary: The development of language skills requires a range of linguistic abilities and cognitive processes, such as executive functions. This study aimed to examine the relationship between specific components of executive functions and language abilities in preschool children. The results showed that working memory and cognitive flexibility significantly contributed to the variance in language abilities, while inhibition skills did not have a significant impact.

Summary: Executive functions and working memory play different roles in decision-making for Alzheimer's disease patients. Inhibition is more related to decision quality, while switching and updating ability, as well as working memory, are involved in decisions inspired by everyday life.

Summary: This study investigated the effects of computerized working memory training on cognitive functioning and symptoms in remitted patients with major depressive disorder. The results showed improvements in cognitive functioning in most conditions, while symptoms did not change. The improvements in computerized working memory training were associated with improvements in some aspects of cognition, but also with worse self-reported attention.

Summary: Studies have found a nominally significant positive correlation between working memory performance and narcissistic traits in subclinical individuals, but further research is needed to establish the association between cognitive performance and narcissistic traits.

Summary: In this study, neuronal and behavioral responses to different levels of predatory threat were examined in the dorsal periaqueductal grey (PAG). The results suggest that the dorsal PAG codes for different levels of predatory threat rather than orchestrating distinct threat-oriented behaviors.

Summary: In nature, confrontations between conspecifics are recurrent and related to the lack of resources. Repeated social defeat can lead to changes in social defence behaviour. The balance of activity between the amygdala, hypothalamic nuclei, and the hypothalamic pre-mammillary nucleus (PMD) may determine the pattern of social defence behaviour.

Summary: Previous studies have found that the basolateral amygdala (BLA) and the ventral hippocampus (VH) play critical roles in predator-related fear memory storage. Protein synthesis and glucocorticoid hormones are involved in modulating this process. Exposure to a predatory threat leads to rapid glucocorticoid release and facilitates fear memory consolidation.

Summary: The present study systematically analyzed the afferent and efferent projections of the CUN and investigated its role in fear responses. The CUN was found to be a caudal component of the periaqueductal gray and had strong links with the dorsolateral periaqueductal gray. It was also found to mediate innate antipredatory responses but not learned fear responses.
