Summary: An increasing number of studies have found that symptoms of attention deficit hyperactivity disorder (ADHD) are risk factors for technology addictions among young adults, particularly in terms of social media and smartphone addiction. Symptoms of inattention have a smaller impact on internet addiction. This study suggests that individuals with non-clinical, trait-level ADHD, especially those with more symptoms of inattention, are more susceptible to developing certain forms of technology addiction.

Summary: The study revealed that low birth weight below 2000 g and genetic risk of ADHD contribute to higher levels of ADHD traits among Japanese children aged 8 to 9 years. The association between low birth weight and ADHD is limited to children with a genetic susceptibility to ADHD, highlighting the relevance of genetic-environmental interactions in the etiology of the disorder.

Summary: This study examines the associations between polygenic risk score (PRS) for attention deficit and hyperactivity disorder (ADHD) and ADHD symptoms in 5-year-old children, sleep duration throughout childhood, and the interaction between PRS for ADHD and short sleep duration relative to ADHD symptoms at 5 years. The results suggest that PRS for ADHD is associated with ADHD symptoms, and parent-reported short sleep moderates the association between genetic risk of ADHD and ADHD symptoms.

Summary: The study found that task-related alpha interhemispheric connectivity changes during a unimanual finger-tapping task are correlated with severity of inattentive symptoms, but not with severity of hyperactive/impulsive symptoms. This neurobiological dissociation in ADHD symptom severity has implications for understanding the structure of endophenotypes in the disorder and for biomarker development.

Summary: This study aims to systematically review and meta-analyze the effect of MBIs (Mindfulness, Tai Chi, Yoga, and Qigong) on symptoms and executive function in ADHD. Randomized controlled trials on the effects of MBIs on symptoms and executive function in ADHD were collected from multiple databases. The pooled meta-analyses showed a positive and small effect of MBIs on inattention, hyperactivity/impulsivity, and executive function. The results suggest that MBIs have a significant improvement compared to the control condition.

Summary: This study aims to assess whether dogs can exhibit ADHD-like behaviors and verify the reliability of the questionnaire used to evaluate these behaviors. The results showed that the questionnaire is a reliable tool to assess ADHD-like behavior in dogs. However, further evaluation using expert ratings and assessment of functional impairment in daily life is necessary to determine whether individual dogs can be diagnosed with ADHD.

Summary: The objective of this study was to explore the diagnostic performance of a screening instrument for ADHD and its association with impairment using DSM-5 ADHD symptom criteria in a sample of students from Mozambique. The results showed poor performance of the screening instrument in predicting ADHD diagnosis, but the DSM-5 recommended six symptoms cutoff showed better prediction of impairment. The findings suggest the adequacy of DSM-5 ADHD criterion A in an African culture.

Summary: ADHD is a complex disorder with impairing symptoms that can benefit from early and accurate diagnosis. Deficits in executive functioning are specific to the inattention domain of ADHD, and the relationship between EF task performance and inattention is consistent across sociodemographic groups. Further research using a bifactor characterization of ADHD in clinical samples is needed to enhance understanding of cognitive deficits across varying symptom presentations.

Summary: Most studies on ADHD focus on comparing healthy subjects and clinical patients, whereas this study looks at the association between natural variability in hyperactivity and inattention scores with EEG dynamics in healthy children. The results suggest that children with higher hyperactivity and inattention scores may have insufficient vigilance in the early stages of perception and compensate by enhancing attention to stimuli. A lack of arousal model in ADHD children is supported by the findings, which show less sensory arousal in the early stages of perception in children with symptoms of inattention.

Summary: Maternal prenatal psychosocial stress is associated with altered hypothalamic-pituitary-adrenal axis (HPAA) function among infants. This study found that altered DNA methylation, specifically in the oxytocin receptor gene, may contribute to the regulation of HPAA during infancy. Maternal distress and anxiety symptoms were negatively associated with DNA methylation and cortisol levels in infants.

Summary: This study aimed to assess physical and mental health, and health-related quality of life parameters in adolescents with physical disabilities compared to adolescents without disabilities during the COVID-19 pandemic. The results showed that adolescents with disabilities had lower emotional and prosocial problems, lower global function, higher happiness scores, more physical activity, and less screen time compared to controls. This suggests that attending a sports NGO has a positive impact on reducing adverse health indicators for adolescents with disabilities.

Summary: Neuroimaging studies suggest that brain development mechanisms may explain some ADHD symptoms. However, the mechanisms by which genetic factors influence brain development in relation to ADHD remain largely unknown. This study aimed to investigate the associations between an ADHD polygenic risk score and brain network functioning. The findings suggest correlations between the ADHD polygenic risk score and the segregation of cingulo-opercular networks and the default mode network, supporting the role of attentional networks and DMN in attention processes. However, these associations were not found at follow-up.

Summary: Gender inequality has been linked to higher mental health risks and lower academic achievement for women globally. Differences in brain structure between men and women may be partially explained by unequal exposure to harsher conditions in gender-unequal countries, leading to worse outcomes for women. A meta-analysis of MRI scans from 139 samples across 29 countries revealed that women in gender-equal countries had no differences or even thicker cortical regions, while those in countries with greater gender inequality had thinner cortices. These findings highlight the potential negative impact of gender inequality on women's brains and the need for policies based on neuroscience for gender equality.
