Summary: This study examined three potential endophenotypes for attention-deficit hyperactivity disorder (ADHD): working memory function, response inhibition, and reaction time variability. The results showed that higher genetic risk for ADHD was associated with higher ADHD traits, as well as poorer working memory performance and increased reaction time variability. Lower working memory performance, poorer response inhibition, and increased reaction time variability were associated with more pronounced ADHD traits. Working memory and reaction time variability partially mediated the relationship between genetic risk for ADHD and ADHD traits, explaining 14% and 16% of the association, respectively.

Summary: This study investigates the neural links between ADHD symptoms and prolonged screen time utilization (STU) using a large-scale dataset. The findings suggest that higher polygenic risk scores for ADHD are associated with longer STU and more severe symptoms. White matter microstructure, particularly in visual-related functions, plays a crucial role in mediating the association between ADHD risk and STU.

Summary: There is a clear link between ADHD, impulsivity features, and overweight/obesity, with neural and polygenic correlates playing a role in this association. The study found shared neural substrate associated with impulsivity symptoms, BMI, and their respective polygenic risk scores, indicating a common genetic liability for ADHD and BMI. Impulsivity symptoms and BMI were also mediated by neuroimaging substrate, revealing a potential underlying mechanism for their phenotypic association.

Summary: Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) are co-occurring neurodevelopmental conditions with strong, discordant polygenic associations with educational attainment. Genetic architectures of ASD and ADHD exhibit similarities but also differences, including polygenic associations with educational attainment. Through multivariable regression analyses, it is found that genetic variation related to educational attainment is shared across ASD and ADHD architectures, involving identical marker alleles. This suggests a polygenic form of pleiotropy contributing to the detectable genome-wide correlation between ASD and ADHD.

Summary: This study systematically reviewed randomized clinical trials of various psychotropic medications for the treatment of disruptive behavior (DB) in youths, and used network meta-analysis to compare their relative efficacy. The results showed that second-generation antipsychotics, stimulants, and non-stimulant ADHD medications were more effective than placebo for reducing DBs, with second-generation antipsychotics being the most efficacious. The study provides valuable information on the relative efficacy of different psychotropic medications for DB treatment and insight into potential neurobiological mechanisms underlying these symptoms.

Summary: The study investigates whether a high polygenetic predisposition to ADHD exacerbates the risk of all-cause mortality in older adults from the general population in the UK. The results show that a high polygenetic predisposition to ADHD is a risk factor for all-cause mortality in older adults, and this risk is better captured when incorporating genetic information from correlated traits.

Summary: This study investigates process-oriented verbal fluency measures in adults with ADHD and adults with BD in a hypomanic episode. The results show that both groups exhibit increased switching in the verbal fluency tasks compared to healthy controls. Additionally, the hypomanic group shows increased phonological clustering in the semantic task. These findings suggest that semantic overactivation and unusual sounds-based associations contribute to racing thoughts in both ADHD and BD.

Summary: This cohort study found that prenatal exposure to illicit drugs is significantly associated with the development of neurodevelopmental and disruptive behavioral disorders in children aged 7-12 years. The study included over 800,000 primiparous women in Taiwan and identified the risks of various disorders associated with drug exposure. Methamphetamine and opioid use were found to increase the risk of neurodevelopmental disorders, while sedative hypnotic drugs alone did not show an increased risk. However, a significant interaction effect was observed when sedative hypnotic drugs were used in combination with illicit drugs.

Summary: This study examined the relationship between polygenic liability for depression and number of stressful life events (SLEs) as risk factors for early-onset depression treated in psychiatric hospitals in Denmark. The results showed that the risk for depression increased with higher polygenic liability and more SLEs, and there was a small interaction between these two factors. Combining information on these two risk factors could potentially be useful for identifying high-risk individuals.

Summary: This study found a genetic overlap between anorexia nervosa (AN), obsessive-compulsive disorder (OCD), and anxiety symptoms, with a potential sex-specific contribution of genetic risk. AN and AN/OCD polygenic scores (PGS) played a more prominent role in predicting eating disorder and anxiety symptoms, while OCD PGS had a smaller effect. The results also suggest that compulsive exercise may have a transdiagnostic genetic etiology.

Summary: Exposure to childhood adversity has been consistently associated with poor developmental outcomes, but it is unclear whether these associations vary across different forms of adversity. This study examined the associations between threat and deprivation with cognition, emotional processing, and psychopathology in a middle-income country using a longitudinal design. The results showed differential associations between threat and deprivation with cognitive development and psychopathology.

Summary: The COVID-19 pandemic had a negative impact on the mental health of individuals with neurodevelopmental disorders, including autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD). A study using data from the Avon Longitudinal Study of Parents and Children examined the effects of the pandemic on anxiety, depression, and mental wellbeing in adults with NDDs. The study found that individuals with ADHD and ASD had higher rates of depression, anxiety, and poor mental wellbeing compared to those without these disorders. The pandemic had a greater impact on anxiety levels in individuals with ADHD and ASD, while depressive symptoms decreased, particularly in females with ASD. Overall, mental wellbeing decreased for all participants, but to a lesser extent in those with ADHD and females with ASD.

Summary: This study conducted a meta-analysis of genome-wide association studies on ADHD and identified 27 significant genetic loci associated with ADHD. They also found that these loci were enriched with genes involved in early brain development. Moreover, they discovered an increased load of rare protein-truncating variants in ADHD, implicating SORCS3 as a potential gene involved in ADHD.

Summary: In this study, a multi-trait genome-wide association study was conducted to explore the genetic overlap between irritable bowel syndrome (IBS), neuroticism, depression, and anxiety. The results revealed a polygenic architecture for IBS and identified novel genetic variants associated with the disorder. The analysis also showed bidirectional causal effects between IBS and neuroticism and depression, as well as the genetic liability of IBS on anxiety. These findings contribute to our understanding of the genetic basis and relationships between gastrointestinal and mental disorders.

Summary: Although the association between maternal exposure to adverse childhood experiences (ACEs) and perinatal anxiety and depression is known, the relationship between ACEs and perinatal trauma and post-traumatic stress outcomes is poorly understood. This study found that pregnant women who experienced ACEs were more likely to experience perinatal trauma, with a significantly increased risk compared to those who did not report ACEs. The highest risk of perinatal trauma was associated with ACEs related to abuse or neglect. Therefore, routine screening for ACEs during pregnancy is important for addressing perinatal mental health.

Summary: Data aggregation in mental health is complicated due to the use of different questionnaires, and the impact of item harmonization strategies on measurement precision is not well understood. This study aimed to assess the impact of various item harmonization strategies for a target and proxy questionnaire. The results showed that the one-by-one expert-based semantic item harmonization was the best strategy, resulting in scalar-invariant models for both samples and factor models. Furthermore, item harmonization strategies had little impact on p-factors and first-order correlated factors when harmonizing the child behavior checklist (CBCL) and strengths and difficulties questionnaire (SDQ), but were relevant for specific factors in bifactor models.

Summary: This study found that individuals with ADHD have lower motivation in both cognitive and physical domains, and amphetamine-based medication can increase their motivation. The results also showed that amphetamine treatment effectively restores motivation in ADHD individuals, bringing it to levels similar to healthy controls. These findings provide clear evidence for increased sensitivity to effort in individuals with ADHD and demonstrate the domain-general role of catecholamines in motivating effortful behavior.

Summary: This review summarizes and interprets the genetic architecture of comorbidities between attention-deficit/hyperactivity disorder (ADHD) and other psychiatric disorders and traits. Quantitative genetic studies indicate the substantial role of genetic factors in the co-occurrence of ADHD with various disorders and traits, and molecular genetic correlations from genome-wide association studies provide smaller effect estimates compared to twin studies. The identification of specific genetic variants and biological pathways underlying comorbidity is still in its early stages. Causal inference analyses using genetic data support causal relationships between ADHD and comorbid disorders, but bidirectional effects suggest complex relationships.

Summary: Synaesthesia is a sensory phenomenon where external stimuli trigger additional sensations. It aggregates in families and is associated with the autism spectrum and autistic traits. Individual differences in self-reported synaesthesia are heritable and influenced by genetic factors, while the association with autistic traits is predominantly under genetic influence and mainly driven by non-social traits.
