Subclinical attention-deficit hyperactivity disorder symptoms and unhealthy lifestyle behaviours.

BACKGROUND: Literature emphasises the importance of identifying and intervening in the adoption of unhealthy lifestyle behaviours (ULBs) during adolescence at an early stage, to mitigate their long-term detrimental effects. Among the possible associated factors contributing to ULBs, attention-deficit hyperactivity disorder (ADHD) has been shown to play an important role. However, little is known about ADHD subclinical manifestations. AIMS: The present study aimed to bridge the gap in the literature and shed light on the relationship between subclinical ADHD and early adoption of ULBs during adolescence. Through a clinimetric approach, prevalence of ULBs, severity of ADHD symptoms and psychosocial factors (i.e. allostatic overload, abnormal illness behaviour, quality of life, psychological well-being) were investigated among adolescents. The associations between different degrees of ADHD, ULBs and psychosocial factors were also explored. METHOD: This multicentre cross-sectional study involved 440 adolescents (54.5% females; mean age 14.21 years) from six upper secondary schools. Participants completed self-report questionnaires on sociodemographic characteristics, ULBs, ADHD symptoms and psychosocial factors. RESULTS: The most common ULBs were energy drinks/alcohol consumption and problematic smartphone use. Of the sample, 22% showed subclinical ADHD and 20.2% showed clinical ADHD. The subclinical ADHD group showed several ULBs (i.e. altered mindful eating, impaired quality of sleep, problematic technology use) and psychosocial factors, akin to those of ADHD group and different from peers without ADHD symptoms. CONCLUSIONS: Since subclinical ADHD manifestation is associated with ULBs, similarly to clinical ADHD, identifying subthreshold symptoms during adolescence is crucial, as it could improve health-related outcomes in adulthood across different domains.

Lisdexamfetamine's Efficacy in Treating Attention Deficit Hyperactivity Disorder (ADHD): A Meta-Analysis and Review.

Lisdexamfetamine dimesylate, a prodrug stimulant, appears to effectively treat Attention-Deficit/Hyperactivity Disorder (ADHD) in children and adults. However, an analysis of the treatment effects of the two subscales (inattentiveness and hyperactivity) within the ADHD Rating Scale-IV (ADHD-RS-IV) has not yet been done to determine if clinical significance may be attributed to either one. Nor has there been a meta-analysis of the individual doses of lisdexamfetamine dimesylate. The current meta-analysis utilizes MEDLINE, Embase, Cochrane, PubMed, and clinicaltrials.gov to identify peer-reviewed studies. Selected studies were eligible if they met the following criteria: English language, randomized-controlled trials, and utilized the ADHD-RS-IV scale to assess the efficacy of lisdexamfetamine on treating ADHD in either children or adults. The primary studies utilized were published between January 2007 and April 2024. Many of these studies calculate effect sizes based on several dosages pooled together rather than by individual dosages. We conducted a random-effects meta-analysis to estimate the effect sizes for these pooled dosages on the full ADHD-RS-IV scale and its subscales, as well as to calculate effect sizes on the same scales based on the individual dosages. Our main outcome measures are the ADHD-RS-IV scale and its subscales in individual doses and pooled results in both children and adults. Adverse events during treatment were also analyzed based on stratified dosages. Eleven publications met our inclusion criteria. The analyses indicate that compared to placebo, lisdexamfetamine effectively alleviates the symptoms outlined by the ADHD-RS-IV. Moreover, there are no differences in the individual subscales or in the safety profile. Lisdexamfetamine demonstrates efficacy in treating the symptoms of ADHD, but we report that differing dosages did not yield significant differences in ADHD symptom management.

The neurodivergent perinatal experience - A systematic literature review on autism and attention deficit hyperactivity disorder.

BACKGROUND: Neurodivergent individuals often face unique challenges during the perinatal period, which can significantly impact their experiences of pregnancy, childbirth, and early parenting. Despite growing awareness of neurodiversity, there remains a gap in perinatal care that fully addresses the lived experiences and needs of those with neurodivergent conditions such as Autism (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). OBJECTIVE: To compile and analyse recent literature on the perinatal experiences of neurodivergent parturients. To provide an overview of current knowledge, identify prevalent challenges, and suggest opportunities for improving perinatal services. Additionally, we aim to highlight research gaps that guide future studies and enhance care quality for neurodivergent individuals during the perinatal period. METHODS: The Systematic Reviews methodological process was utilised to search relevant scientific databases to gather current research articles on neurodivergent perinatal experiences. Eleven studies met the inclusion criteria and were appraised using a rigorous quality checklist. Thematic analysis identified recurring themes across the selected papers. RESULTS: Three major themes emerged: Care provider support, Perinatal mental health needs, and Resilience and growth of neurodivergent parturients. These themes highlight significant differences in perinatal experiences between neurodivergent and neurotypical individuals, underscoring the need for tailored care approaches. CONCLUSION: The findings reveal that current perinatal care practices do not adequately address the specific challenges faced by perinatal neurodivergent individuals. There is a critical need for perinatal care systems to integrate neurodiversity-affirming practices. Future research should consider intersectionality to include marginalised and underrepresented neurodivergent voices.

Scheduling of methylphenidate: Preventing misuse or impeding ADHD treatment adherence?

Background: Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, with a chronic, and potentially debilitating course if untreated. Medication adherence is poor - negatively affecting emotional, social, educational and employment outcomes. The current Schedule 6 status of methylphenidate (MPH) drives healthcare resource utilisation and costs - a potential barrier to care. Aim: This study explored stakeholders' understanding and perceptions of the potential impact of a regulatory shift in the scheduling of MPH on treatment accessibility and adherence for ADHD. Setting: Participants from multiple stakeholder groups, involved in ADHD management in South Africa, were recruited via professional networks. Methods: A qualitative analysis of semi-structured interviews with 23 stakeholders was conducted to explore their views on the utility, benefits and risks associated with rescheduling MPH. Results: Six key themes emerged from the interviews: 'adherence', 'accessibility', 'affordability', 'stigma', 'rescheduling of MPH' and 'risk mitigation'. Core to these themes is the role of the scheduling of MPH - which can have a protective societal role, but also acts as a barrier to care for individuals with ADHD. Conclusion: The current Schedule 6 status of MPH is not an effective strategy to prevent misuse and diversion but negatively impacts on treatment adherence. The positive outlook from stakeholders on rescheduling MPH holds significant implications for the ADHD landscape in South Africa. Contribution: It is crucial to address stigma, facilitate fundamental change in service delivery and remove structural and practical barriers to care to improve outcomes for individuals with ADHD. A framework for ADHD treatment adherence is provided.

A Boy With KIF11-Associated Disorder Along With ADHD and ASD: Collaboration Between Paediatrics and Child Psychiatry.

Kinesin family member 11 (KIF11)-associated disorder, a rare condition caused by autosomal dominant mutations in the KIF11 gene, presents with microcephaly, chorioretinal dysplasia, lymphoedema, and varying degrees of intellectual disability. While intellectual disability is often described in the literature on KIF11 mutations, autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are only mentioned by a few authors but not thoroughly investigated. We present a case report of an 8-year-old boy with KIF11-associated disorder alongside ADHD and ASD but without intellectual disability. Genetic testing confirmed a KIF11 mutation. Cognitive, language, and motor assessments revealed delays in fine motor skills and attention deficits. The diagnosis of ADHD was confirmed by a child neurologist through multidisciplinary investigations, while the ASD diagnosis was established by a child psychiatrist. Despite the challenges of delayed psychiatric assessment, interventions including physiotherapy and medication management were initiated with positive results. We designed a parent support group survey that showed a higher prevalence of neurodevelopmental disorders in children with KIF11 mutations compared to the general population. Therefore, low-threshold referrals to a child psychiatrist have to be made when the potential presence of developmental problems is suspected. Collaboration between ophthalmologists, paediatricians, and child psychiatrists is crucial for early detection and intervention. Addressing developmental disorders promptly improves long-term outcomes and enhances quality of life. Moreover, gaining a deeper understanding of the higher prevalence of ASD and ADHD in individuals with KIF11 mutations could offer valuable insights into the genetic mechanisms underlying neurodevelopmental disorders.

Comparison of Brain Function Between Medication-Naïve ADHD with and without Comorbidity in Chinese Children Using Resting-State fNIRS.

Background: This study used functional near-infrared spectroscopy (fNIRS) to investigate brain activation patterns in children with attention deficit hyperactivity disorder (ADHD) with and without additional comorbidities to identify disease-related biomarkers by the neuroimaging that will facilitate to make a diagnosis decision. Methods: In this study, 165 medication-naive children aged 7 to 15 years were recruited and categorized into four groups: ADHD, ADHD with learning disabilities (ADHD&LD), ADHD with oppositional defiant disorder (ADHD&ODD), and healthy controls. A multichannel fNIRS system was used to monitor hemodynamic changes at rest state in the prefrontal and temporal lobes of the brain. The amplitude of a low-frequency fluctuation (ALFF) matrix was calculated by summation and averaging of the square root of the signal power spectrum. One-way analysis of variance was used to identify statistical differences between channels. Results: All ADHD children presented significantly higher ALFF values in different brain regions when compared with the healthy controls. Patients with ADHD&LD exhibited higher ALFF values in the medial prefrontal cortex (P Ch38 = .01, P Ch48 = .01), temporal cortex (P Ch22 = .04, P Ch41 = .002, P Ch51 = .001), and the left ventrolateral prefrontal cortex (P Ch39 = .0009, P Ch50 = .001), whereas ADHD&ODD children were not significantly different to those diagnosed with ADHD. Conclusions: ADHD with learning disabilities (LD) possessed a different pathogenesis from ADHD, manifested as lower functional brain activity in the medial prefrontal cortex, temporal cortex, and the left ventrolateral prefrontal cortex, while ADHD&ODD did not present significant changes compared with ADHD. ODD-related symptoms may be part of ADHD symptoms rather than being an independent disorder.

Comparative analysis of electroencephalogram (EEG) data gathered from the frontal region with other brain regions affected by attention deficit hyperactivity disorder (ADHD) through multiresolution analysis and machine learning techniques.

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by repeated patterns of hyperactivity, impulsivity, and inattention that limit daily functioning and development. Electroencephalography (EEG) anomalies correspond to changes in brain connection and activity. The authors propose utilizing empirical mode decomposition (EMD) and discrete wavelet transform (DWT) for feature extraction and machine learning (ML) algorithms to categorize ADHD and control subjects. For this study, the authors considered freely accessible ADHD data obtained from the IEEE data site. Studies have demonstrated a range of EEG anomalies in ADHD patients, such as variations in power spectra, coherence patterns, and event-related potentials (ERPs). Some of the studies claimed that the brain's prefrontal cortex and frontal regions collaborate in intricate networks, and disorders in either of them exacerbate the symptoms of ADHD. , Based on the research that claimed the brain's prefrontal cortex and frontal regions collaborate in intricate networks, and disorders in either of them exacerbate the symptoms of ADHD, the proposed study examines the optimal position of EEG electrode for identifying ADHD and in addition to monitoring accuracy on frontal/ prefrontal and other regions of brain our study also investigates the position groupings that have the highest effect on accurateness in identification of ADHD. The results demonstrate that the dataset classified with AdaBoost provided values for accuracy, precision, specificity, sensitivity, and F1-score as 1.00, 0.70, 0.70, 0.75, and 0.71, respectively, whereas using random forest (RF) it is 0.98, 0.64, 0.60, 0.81, and 0.71, respectively, in detecting ADHD. After detailed analysis, it is observed that the most accurate results included all electrodes. The authors believe the processes can detect various neurodevelopmental problems in children utilizing EEG signals.

Does Temperament Constitute a Risk Factor for Adult Attention Deficit Hyperactivity Disorder?

OBJECTIVE: The aim of this study was to examine the temperament characteristics of adults with attention deficit hyperactivity disorder (ADHD) and the relationship between ADHD subtypes and temperament. Additionally, the study aimed to investigate the relationship between childhood ADHD symptoms and temperament. METHODS: The study included 59 ADHD patients aged between 18 and 60 years and 44 healthy controls. All participants completed the Wender-Utah Rating Scale (WURS) and the Adult Attention Deficit Hyperactivity Disorder Diagnosis and Rating Scale. Temperament characteristics were assessed using the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego-Autoquestionnaire scale (TEMPS-A). RESULTS: The ADHD group had significantly higher scores for cyclothymic, irritable, and anxious temperament compared to the control group (p<0.001). The number of individuals with cyclothymic, irritable, and anxious temperament was also significantly higher in the ADHD group (p=0.007, p=0.018, p=0.029, respectively). Positive correlations were found between cyclothymic and depressive temperament scores and WURS scores (r=0.278, p=0.033; r=0.326, p=0.012, respectively), between hyperthymic temperament scores and hyperactivity scores (r=0.399, p=0.002), and between depressive temperament scores and attention deficit scores (r=0.303, p=0.020). There was no relationship between ADHD subtypes and dominant temperament (p>0.05). CONCLUSION: The most common dominant temperament in the ADHD group was cyclothymic, irritable, and anxious. The positive correlation between WURS scores and cyclothymic temperament suggests that cyclothymic temperament may be a risk factor for adult ADHD.

Bidirectional association between allergic rhinitis and attention-deficit/hyperactivity disorder: A systematic review and meta-analysis.

BACKGROUND: This meta-epidemiological study seeks to further investigate the reciprocal relationship between allergic rhinitis (AR) and attention-deficit/hyperactivity disorder (ADHD). METHODS: A comprehensive search of the databases was conducted up to March 3, 2024. We performed a synthesis and meta-analysis of odds ratios and their corresponding 95 % confidence intervals using Stata 14.0. Funnel plot analysis and Egger's regression test were utilized to assess potential publication bias. RESULTS: Eighteen articles involving 4,289,444 participants were included. AR patients had an increased risk of developing ADHD (OR: 1.83; 95 % CI: 1.37-2.43), while ADHD patients were also more likely to have AR (OR: 1.38; 95 % CI: 1.11-1.72). Subgroup analysis indicated a predisposition of AR patients to autism spectrum disorder (OR: 1.34; 95 % CI: 0.86-1.0) and a higher risk of ADHD in cohort studies (OR: 1.90; 95 % CI: 1.26-2.88). Female AR patients were more likely to develop ADHD than males (OR: 1.86; 95 % CI: 1.43-2.43), and children aged ≤8 years with AR were at greater risk for ADHD compared to older children (OR: 1.75; 95 % CI: 1.14-2.69). CONCLUSIONS: This meta-analysis confirms a bidirectional association between AR and ADHD, indicating that they are mutually independent risk factors.

Relationships between screen time and childhood attention deficit hyperactivity disorder: a Mendelian randomization study.

Background: In previous observational studies and meta-analyses, childhood attention deficit hyperactivity disorder (ADHD) is found to have a significant association with screen time. However, the causal associations between them remain unclear. Method: This study performed a bidirectional two-sample Mendelian randomization (MR) analysis to confirm the causality between screen time and childhood ADHD. Large-scale genome-wide association studies (GWAS) datasets derived from the Psychiatric Genomics Consortium (PGC) and the UK Biobank were used to identify single nucleotide polymorphisms (SNPs) associated with exposure and outcome. Four categories of datasets were selected to represent screen time. The SNPs that are significantly associated with exposure data (P < 5e-08) and have a strong correlation with the exposure in the F-statistic (F > 10) were selected as instrumental variables. This study also used the PhenoScanner V2 database and the LDlink webtool to exclude confounding factors, and the MR-PRESSO method (p < 0.05) was employed to eliminate outliers with bias. Five commonly used methods were employed to assess the interaction and the Inverse Variance Weighted (IVW) method was utilized as the primary basis for determining the MR estimates in this study. Results: The MR analysis revealed that the length of mobile phone use (OR, 1.848; 95% CI, 1.3360-2.5558; p=2.07e-4) and the time spent watching television (OR, 2.104; 95% CI, 1.3958-3.1703; p=3.8e-4) increased the risk of childhood ADHD. Although the causal relationships were exclusively identified through the IVW and weighted median methods, the results retained their statistical significance following correction. In the reverse analysis, no evidence was found to support an effect of childhood ADHD on screen time. The sensitivity analysis conducted on the significant findings revealed no evidence of horizontal pleiotropy or heterogeneity. Conclusion: This study provides some evidence for the causality of screen time and childhood ADHD. Given the limitations of our study, further research is required to comprehensively investigate this relationship.

Contrasting Deficits in the Function of the Phonological Loop Between Children With Attention Deficit Hyperactivity Disorder and Reading Disability.

Attention Deficit Hyperactivity Disorder (ADHD) and reading disability (RD) often co-occur. Impairments in the phonological loop of working memory are central to RD, but it is unclear whether this is linked to ADHD, especially in Chinese reading. Two experiments were conducted with Chinese children aged 7 to 12 (Experiment 1, n = 65; Experiment 2, n = 60). Immediate and delayed recognition paradigms were used to assess phonological encoding and rehearsal. Both the RD-only and comorbid (ADHD + RD) groups performed worse than the control and ADHD-only groups in response time and accuracy. Notably, the comorbid group performed similarly to the RD-only group, indicating that phonological loop deficits in comorbid children are likely due to RD, not ADHD. This highlights phonological loop function as the key to distinguishing between ADHD and RD.

Prevalence of attention-deficit hyperactivity disorder (ADHD): systematic review and meta-analysis.

BACKGROUND: The estimates of attention-deficit hyperactivity disorder (ADHD) prevalence across various studies are significantly variable, contributing to uncertainty in ADHD prevalence estimation. Previous systematic reviews and meta-analyses have attributed this variability primarily to the methodological characteristics of the studies, including the diagnostic criteria, source of information, and impairment requirement for the diagnosis. METHODS: Review identified studies reporting ADHD prevalence in representative samples of children and adults in Europe and worldwide. Studies that were conducted in the general population were included. We focused on studies that report ADHD prevalence based on clinical diagnosis (clinical diagnostic criteria based on the Diagnostic and Statistical Manual of Mental Disorders and International Classification of Diseases criteria, other diagnostic tools, such as various scales or interviews based on clinical diagnostic criteria). PubMed/Medline was searched to identify relevant articles published until 2024/2/01. The study was registered in PROSPERO (CRD42020200220) and followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines for systematic review and meta-analysis. RESULTS: In total, 117 studies were subjected to full evaluation. In the meta-analysis, 103 studies representing 159 independent datapoints were included. The overall prevalence of ADHD in register studies was 1.6%, 95% CI [0.9; 3.0], in survey studies 5.0%, 95% CI [2.9; 8.6], in one-stage clinical studies 4.2%, 95% CI [2.9; 6.0], and in two-stage clinical studies 4.8%, 95% CI [4.0; 5.8]. CONCLUSIONS: Exact comparisons among studies with different diagnostic criteria and types of sampling can impact prevalence estimates. When comparing data from methodologically different studies, these factors need to be considered.

A data science approach to optimize ADHD assessment with the BRIEF-2 questionnaire.

Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder. A key challenge associated with this condition is achieving an early diagnosis. The current study seeks to anticipate and delineate the assessments offered by both parents and teachers concerning a child's behavior and overall functioning with the Behavior Rating Inventory of Executive Function-2 (BRIEF-2). Mothers, fathers, and teachers of 59 children diagnosed or in the process of being assessed for ADHD participated in this study. The responses provided by 59 mothers, 59 fathers, and 57 teachers to the BRIEF-2 questionnaire were collected. The performance of various feature selection techniques, including Lasso, decision trees, random forest, extreme gradient boosting, and forward stepwise regression, was evaluated. The results indicate that Lasso stands out as the optimal method for our dataset, striking an ideal balance between accuracy and interpretability. A repeated validation analysis reveals an average positive correlation exceeding 0.5 between the inattention/hyperactivity scores reported by informants (mother, father, or teacher) and the predictions derived from Lasso. This performance is achieved using only approximately 18% of the BRIEF-2 items. These findings underscore the usefulness of variable selection techniques in accurately characterizing a patient's condition while employing a small subset of assessment items. This efficiency is particularly valuable in time-constrained settings and contributes to improving the comprehension of ADHD.

Exploring causal associations of antioxidants from supplements and diet with attention deficit/hyperactivity disorder in European populations: a Mendelian randomization analysis.

Background: Antioxidants from both supplements and diet have been suggested to potentially reduce oxidative stress in individuals with ADHD. However, there is a lack of studies utilizing the Mendelian randomization (MR) method to explore the relationship between dietary and supplemental antioxidants with ADHD. Methods: This study employed two-sample mendelian randomization. Various specific antioxidant dietary supplements (such as coffee, green tea, herbal tea, standard tea, and red wine intake per week), along with diet-derived circulating antioxidants including Vitamin C (ascorbate), Vitamin E (α-tocopherol), Vitamin E (γ-tocopherol), carotene, Vitamin A (retinol), zinc, and selenium (N = 2,603-428,860), were linked to independent single nucleotide polymorphisms (SNPs). Data on ADHD was gathered from six sources, comprising 246,888 participants. The primary analytical method utilized was inverse variance weighting (IVW), with sensitivity analysis conducted to assess the robustness of the main findings. Results: In different diagnostic periods for ADHD, we found that only green tea intake among the antioxidants was significantly associated with a reduced risk of ADHD in males (OR: 0.977, CI: 0.963-0.990, p < 0.001, FDR = 0.065), with no evidence of pleiotropy or heterogeneity observed in the results. Additionally, a nominal causal association was found between green tea intake and childhood ADHD (OR: 0.989, 95% CI: 0.979-0.998, p = 0.023, FDR = 0.843). No causal relationships were detected between the intake of other antioxidant-rich diets and ADHD. Conclusion: Our study found a significant inverse association between green tea intake and male ADHD, suggesting that higher green tea consumption may reduce ADHD risk in males. Further research is needed to explore optimal doses and underlying mechanisms.

Loss of Control Eating in Adults With Impulsive and/or Inattentive Tendencies.

OBJECTIVE: Previous research has tended to consider impulsive, inattentive, and loss of control eating (LOC) tendencies as symptoms of greater pathologies in treatment-seeking samples. However, inattentive and impulsive tendencies and LOC often co-occur. Although LOC is an important diagnostic component of disordered eating (ED), it has recently been argued to be a dysregulated eating behavior in its own right. The purpose of the current self-report study was, therefore, to investigate the association between impulsive and inattentive tendencies and LOC in adults after accounting for ED. METHOD: A community sample of 516 adults was surveyed online about their inattentive and impulsive tendencies, LOC, and ED behaviors. RESULTS: A hierarchical multiple linear regression revealed ED, inattentive, and impulsive symptoms to be independent, significant, positive predictors of LOC. DISCUSSION: These findings suggest that the levels of inattentive and, to a lesser extent, impulsive tendencies are significantly associated with LOC in adults, even after ED is accounted for. Moreover, inattentive tendencies were found to be more significantly associated with LOC than impulsive tendencies. These are novel and important findings that can be used to inform both clinicians and individuals with inattentive and impulsive tendencies alike of this association. Considering the well-documented adverse health and wellbeing outcomes associated with LOC, future feasibility trials are needed aimed at treating this co-occurrence.

Tanshinone IIA Exerts Cardioprotective Effects Through Improving Gut-Brain Axis Post-Myocardial Infarction.

Myocardial infarction (MI) is a lethal cardiovascular disease worldwide. Emerging evidence has revealed the critical role of gut dysbiosis and impaired gut-brain axis in the pathological progression of MI. Tanshinone IIA (Tan IIA), a traditional Chinese medicine, has been demonstrated to exert therapeutic effects for MI. However, the effects of Tan IIA on gut-brain communication and its potential mechanisms post-MI are still unclear. In this study, we initially found that Tan IIA significantly reduced myocardial inflammation, apoptosis and fibrosis, therefore alleviating hypertrophy and improving cardiac function following MI, suggesting the cardioprotective effect of Tan IIA against MI. Additionally, we observed that Tan IIA improved the gut microbiota as evidenced by changing the α-diversity and ß-diversity, and reduced histopathological impairments by decreasing inflammation and permeability in the intestinal tissues, indicating the substantial improvement of Tan IIA in gut function post-MI. Lastly, Tan IIA notably reduced lipopolysaccharides (LPS) level in serum, inflammation responses in paraventricular nucleus (PVN) and sympathetic hyperexcitability following MI, suggesting that restoration of Tan IIA on MI-induced brain alterations. Collectively, these results indicated that the cardioprotective effects of Tan IIA against MI might be associated with improvement in gut-brain axis, and LPS might be the critical factor linking gut and brain. Mechanically, Tan IIA-induced decreased intestinal damage reduced LPS release into serum, and reduced serum LPS contributes to decreased neuroinflammation with PVN and sympathetic inactivation, therefore protecting the myocardium against MI-induced injury.

Preauricular versus intraoral condylectomy for the treatment of unilateral condylar hyperactivity.

In this study we retrospectively reviewed our clinic's treatment of unilateral condylar hyperactivity (UCH). We used computer-guided proportional condylectomy, which was conducted both through preauricular and intraoral approaches, then analysed the advantages and disadvantages of the two techniques. A computer-guided treatment algorithm is also presented. We enrolled 42 patients diagnosed with clinical asymmetry, with or without associated dentofacial deformities, which had been confirmed by single photon emission computed tomography (SPECT) to be UCH. These patients underwent proportional condylectomy: 26 of them had isolated proportional condylectomy, while 16 had proportional condylectomy with concomitant orthognathic surgery. The intraoral approach demonstrated a capacity and precision that was nearly equivalent to the extraoral approach. This mitigates the significant surgical risks associated with the extraoral approach, but it is important to acknowledge the learning curve associated with the intraoral approach. Utilising virtual surgical planning (VSP) and custom cutting guides is essential.

Investigating Attention Deficit Hyperactivity Disorder Symptoms, Emotional Dysregulation and Family Functioning in Children: A Community-Based Study in Elementary Schools in Surabaya, Indonesia.

Objectives: Research on emotional dysregulation related to attention deficit hyperactivity disorder (ADHD) symptoms and its effects on family functioning in children is scarce. This is the first study conducted in Indonesia to examine the intricate relationships between ADHD symptoms, emotional regulation, and family functioning in children. Methods: A cross-sectional survey was conducted involving primary caregivers of children aged 9-13 years old across three elementary schools in Surabaya, using validated questionnaires comprising the Indonesian ADHD Rating Scale, Emotion Regulation Checklist, and Family APGAR scale. Results: The findings revealed a positive association between ADHD features and the emotional lability/negativity subscale (ERLN) (r=0.528; p<0.001), but not the emotion regulation subscale (EREG). Moreover, family functioning positively correlated with ERLN (r= -0.269; p=0.003) and negatively correlated with EREG (r=0.331; p<0.001). Parental education emerged as a significant demographic factor, with higher education levels linked to better emotion regulation (r=0.297; p=0.001). Conclusion: These findings underscore the importance of addressing ADHD symptoms and emotional dysregulation in children in order to enhance family functioning and overall well-being. Implications for future research and interventions targeting emotion regulation, especially in children with ADHD and their families, are also discussed.

Binge, Purge, and Wander: Navigating Bulimia and Attention Deficit Hyperactivity Disorder (ADHD).

A 32-year-old woman with no prior medical conditions, but a history of anorexia nervosa (AN) diagnosed in adolescence, was referred for evaluation by an eating disorders (ED) specialist due to worsening bingeing and purging behaviors. Her clinical presentation was characterized by a body mass index (BMI) approaching the underweight range and frequent bingeing and purging episodes occurring twice daily, consistent with a diagnosis of BN. No other medical or psychiatric comorbidities were diagnosed, including mood, anxiety, and substance use disorders, which are often comorbid with ED. However, the patient reported significant difficulties in managing both personal and professional activities, attributing these challenges to impaired concentration. She had difficulty staying focused on tasks and was easily distracted by unrelated thoughts or stimuli. As a result, she often procrastinated on household and self-care tasks. She also reported problems with time management, frequently arriving late to work, struggling to complete assignments on time, and underestimating how long tasks would take. Initial treatment with fluoxetine and cognitive behavioral therapy (CBT) yielded no substantial improvement. Given the presence of symptoms suggestive of attention deficit hyperactivity disorder (ADHD), a one-month trial of lisdexamfetamine (LDX) was initiated. This intervention resulted in a marked reduction in bingeing and purging episodes and a notable improvement in the patient's concentration, thereby enhancing her overall quality of life. The importance of ADHD screening is underscored, particularly for high-functioning adult women who may not present typical symptoms. In this case, a thorough clinical assessment and detailed anamnesis raised suspicion of previously unrecognized ADHD, that may have been present since childhood. Although the literature on the comorbidity of ADHD and BN is limited, this case highlights a potential link between the two conditions. The significant improvement observed following the introduction of psychostimulants supports the hypothesis that untreated ADHD may contribute to the exacerbation of BN symptoms. Further research is essential to clarify the underlying mechanisms and establish a solid scientific basis for future clinical interventions and therapeutic strategies.

Visualizing changes in cerebral hemodynamics in children with ADHD who have discontinued methylphenidate: A pilot study on using brain function for medication discontinuation decisions.

OBJECTIVE: This study undertook neuropharmacological research on the clinical course of controlled medication discontinuation to guide practitioners who are considering stopping medications for youths with attention-deficit hyperactivity disorder (ADHD). METHODS: This study analyzed the data for 14 ADHD children (12 male and 2 female) in two datasets: The children prescribed methylphenidate (MPH) were at an initial mean age of 7.5 years (SD = 1.70, range: 6-11) with a mean ADHD-Rating Score (ADHD-RS) of 26.6 (SD = 8.64, range 15-40). The children who discontinued MPH based on clinical judgment were at a mean age of 12.21 years (SD = 2.12, range: 8-15) with a mean ADHD-RS of 15.9 (SD = 6.86, range 5-27). The go/no-go task was used to assess response inhibition, while functional near-infrared spectroscopy (fNIRS) was used to measure cerebral hemodynamics. Oxygenated hemoglobin (Oxy-Hb) values from fNIRS data were analyzed for each subject, focusing on past and current measurements. Baseline was set at 10 s pre-task, with interval means from 4 to 24 s analyzed. One-sample t-tests were used to evaluate brain activity magnitude. RESULTS: The results of the study demonstrate that the children who had discontinued the medication exhibited activation in specific brain regions including the frontopolar cortex and the right ventrolateral prefrontal cortex. Activation (t = 2.363, p = 0.034, Cohen's d = 0.632) was found especially in the right dorsolateral prefrontal cortex during the performance of the go/no-go task. These activated areas were consistent with those observed in a previous study comparing brain activity during a go/no-go task between children with ADHD and healthy children. CONCLUSION: The present study showed differences in cerebral hemodynamics before and after discontinuation of MPH in ADHD children whose ADHD symptoms did not recur after MPH was discontinued. In the near future, further investigations that include control groups will be conducted to demonstrate the effects of MPH prior to discontinuation based on the changes in cerebral blood flow in the right prefrontal cortex, which is involved in behavioral inhibition, as observed in this study. This and future research will facilitate the development of criteria for discontinuing treatment.
