Methods: Resting-state EEG recordings were obtained from 57 children, comprising 28 typically developing children and 29 children diagnosed with ADHD. The EEG signal data from both groups were analyzed. To ensure analytical accuracy, artifacts and noise in the EEG signals were removed using the EEGLAB toolbox within the MATLAB environment. Following preprocessing, a comparative analysis was conducted using various ensemble learning algorithms, including AdaBoost, GBM, LightGBM, RF, XGB, and CatBoost. Model performance was systematically evaluated and optimized, validating the superior efficacy of ensemble learning approaches in identifying ADHD. Conclusion: Applying machine learning techniques to extract features from resting-state EEG signals enabled the development of effective ensemble learning models. Differential entropy and energy features across multiple frequency bands proved particularly valuable for these models. This approach significantly enhances the detection rate of ADHD in children, demonstrating high diagnostic efficacy and sensitivity, and providing a promising tool for clinical application.展开更多

Out of the 183 children in the ADHD group, 25 had comorbid asthma, resulting in a comorbidityrate of 13.66% (25/183), compared to the comorbidity rate of 2.91% (16/549) among the 549 children in the controlgroup. The difference in the asthma comorbidity rate between the two groups was statistically significant (P <0.05). The results of the multivariate logistic regression analysis indicated that family history of asthma and allergicdiseases, maternal complications during pregnancy, maternal use of asthma and allergy medications duringpregnancy, maternal anxiety and depression during pregnancy, and parental relationship status are independentrisk factors increasing the risk of comorbid asthma in children with ADHD (P < 0.05).CONCLUSIONChildren with ADHD were more likely to have comorbid asthma than healthy control children were. A familyhistory of asthma, adverse maternal factors during pregnancy, and parental relationship status were identified asrisk factors influencing the comorbidity of asthma in children with ADHD. Clinically, targeted interventions basedon these factors can be implemented to reduce the risk of comorbid asthma.

At present, however, its etiologies and risk factors are unknown. Transmembrane α-amino-3-hydroxy-5-methyl-4-isoxazolepropionicacid(AMPA) receptor regulatory protein γ-8(TARP γ-8,also known as calcium voltage-gated channel auxiliary subunit gamma 8(CACNG8)) is an auxiliary AMPA receptor(AMPAR) subunit. Here, we report an association between TARP γ-8 and ADHD,whereby adolescent TARP γ-8 knockout(KO) mice exhibitedADHD-likebehaviors,including hyperactivity, impulsivity, anxiety, impaired cognition,and memory deficits. Human single-nucleotide polymorphism(SNP) analysis also revealed strong associations between intronic alleles in CACNG8genes and ADHD susceptibility. In addition,synaptosomal proteomic analysis revealed dysfunction of the AMPA glutamate receptor complex in the hippocampi of TARP γ-8 KO mice.Proteomic analysis also revealed dysregulation of dopaminergic and glutamatergic transmissions in the prefrontal cortices of TARP γ-8 KO mice.Methylphenidate(MPH), which is commonly used to treat ADHD, significantly rescued the major behavioral deficits and abnormal synaptosomal proteins in TARP γ-8 KO mice. Notably, MPH significantly reversed the up-regulation of Grik2 and Slc6a3 in the prefrontal cortex. MPH also significantly improved synaptic AMPAR complex function by up-regulating other AMPAR auxiliary proteins in hippocampal synaptosomes. Taken together, our results suggest that TARP γ-8 is involved in the development of ADHD in humans.This study provides a useful alternative animal model with ADHD-like phenotypes related to TARP γ-8deficiency, which has great potential for the development of new therapies.展开更多

In the present study, we compared brain metabo-lism assessed using fluorine-18-fluorodeoxyglucose positron emission tomography between 14 at-tention-deficit hyperactivity disorder （ADHD） patients and 15 normal controls with scoliosis at resting state by statistical parametric mapping. Glucose metabolism was decreased in the left parahippo-campal gyrus, left hippocampus, left anterior cingulate gyrus, right anterior and posterior lobes of the cerebellum, left superior temporal gyrus, left insula, left medial and middle frontal gyri, right medial frontal gyrus, and left basal ganglia （putamen, amygdala, and caudate nucleus） in children with ADHD. These data suggest that children with ADHD exhibit hypometabolism in various brain regions compared to controls, indicating that ADHD symptoms are unlikely the result of abnormalities in specific areas.展开更多

Methods: We retrospectively surveyed 110 patients with chronic pain visiting the Anesthesiology and Pain Relief Center at the University of Tokyo in Japan, who had also consulted a psychiatrist, between April 2012 and July 2015. Results: Of the total of 110 patients with chronic pain, 35 (31.8%) were also diagnosed with ADHD, and the average Wender Utah Rating Scale (WURS) score among the ADHD patients was 39.0 ± 22.1 (n = 25). Only 36.0% of these patients exceeded the cutoff value, suggesting that 64.0% of the patients with ADHD were not identified by screening with the WURS. Twenty-six patients initiated treatment with ADHD medication, with dosage adjustment completed in 21. Of these 21 patients 20 (95.0%) had improved ADHD symptoms. Improved pain symptoms were observed in 14 patients (66.6%), with a reduction in the pain numerical rating scale of 64.7% ± 30.1%. Conclusions: This is the first study investigating the comorbidity of ADHD and chronic pain at pain clinics showing a high level of comorbidity and amelioration of pain and ADHD symptoms with treatment. Careful interpretation is required when the WURS is used to screen patients with chronic pain.展开更多

This study evaluated the effect of osmotic-release oral system （OROS） methylphenidate （MPH） on cognitive function and academic performance of Chinese school-aged children with ADHD. Methods： This 12-week, prospective, multicenter, open-label, self-controlled study enrolled 153 Chinese school-aged children with ADHD and 41 non-ADHD children. Children with ADHD were treated with once-daily OROS-MPH （18 mg, 36 mg, or 54 mg）. The primary endpoints were Inattention/Overactivity （I/O） with Aggression Conners Behavior Rating Scale （IOWA） and Digit Span Test at week 12 compared with baseline. Secondary endpoints included opposition/defiant （O/D） subscale of IOWA, Clinical Global Impression （CGI）, Coding Test, Stroop Color-word Test, Wisconsin Card Sorting Test （WCST）, academic performance on teacher-rated school examinations, and safety at week 12 compared with baseline. Both non-ADHD and ADHD children received the same frequency of cognitive operational test to avoid the possible bias caused by training. Results： A total of 128 patients were evaluated with cognitive assessments. The OROS-MPH treatment significantly improved IOWA Conners I/O subscale scores at week 12 （3.8 ± 2.3） versus baseline （10.0 ± 2.4; P 〈 0.0001）. Digit Span Test scores improved significantly （P 〈 0.0001 ） with a high remission rate （81.1%） at week 12 versus baseline. A significant （P 〈 0.0001 ） improvement was observed in O/D subscale of IOWA, CGI, Coding Test, Stroop Color-word Test, WCST, and academic performance at week 12 versus baseline. Very few practice-related improvements were noticed in the non-ADHD group at week 12 compared with baseline. No serious adverse events and deaths were reported during the study. Conclusions： The OROS-MPH treatment effectively controlled symptoms of ADHD and significantly improved academic performance and cognitive fimction of Chinese school-aged children with ADHD. The treatment was found to be sate and generally well-tolerated over 12 weeks.展开更多

文摘Objective: This study investigates the auxiliary role of resting-state electroencephalography (EEG) in the clinical diagnosis of attention-deficit hyperactivity disorder (ADHD) using machine learning techniques. Methods: Resting-state EEG recordings were obtained from 57 children, comprising 28 typically developing children and 29 children diagnosed with ADHD. The EEG signal data from both groups were analyzed. To ensure analytical accuracy, artifacts and noise in the EEG signals were removed using the EEGLAB toolbox within the MATLAB environment. Following preprocessing, a comparative analysis was conducted using various ensemble learning algorithms, including AdaBoost, GBM, LightGBM, RF, XGB, and CatBoost. Model performance was systematically evaluated and optimized, validating the superior efficacy of ensemble learning approaches in identifying ADHD. Conclusion: Applying machine learning techniques to extract features from resting-state EEG signals enabled the development of effective ensemble learning models. Differential entropy and energy features across multiple frequency bands proved particularly valuable for these models. This approach significantly enhances the detection rate of ADHD in children, demonstrating high diagnostic efficacy and sensitivity, and providing a promising tool for clinical application.

文摘BACKGROUND Attention-deficit hyperactivity disorder(ADHD)and its pharmacological treatments may influence growth in children and adolescents.This meta-analysis aimed to clarify their effects on the physical development,especially weight and height.AIM To investigate the effects of ADHD and its treatment on growth in children and adolescents.METHODS Researchers reviewed 18 studies published up to September 2023 from databases such as PubMed,EMBASE,Cochrane,and Web of Science.They analyzed changes in body weight,height,and body mass index(BMI)before and after ADHD treatment,along with the risks of overweight and obesity.RESULTS Children with ADHD undergoing long-term medication therapy showed decreased actual weight[weighted mean difference(WMD)=-9.50]and height(WMD=-0.15),along with a slight increase in weight standard deviation scores(WMD=0.23)and height z scores(WMD=0.10).BMI showed a non-significant downward trend(WMD=-1.72).Regarding overweight and obesity risks,the pooled odds ratios were 1.37 and 1.16,respectively,but these were not statistically significant.CONCLUSION Overall,the study suggests that long-term pharmacological treatment for ADHD may be associated with reduced growth in weight and height among young patients.However,no clear link was found between ADHD and increased risk of overweight or obesity.These findings highlight the importance of monitoring growth in children receiving medication for ADHD.
文摘BACKGROUND Bronchial asthma is closely related to the occurrence of attention-deficit hyperactivity disorder(ADHD)in children,which can easily have adverse effects on children’s learning and social interactions.Studies have shown that childhood asthma can increase the risk of ADHD and the core symptoms of ADHD.Compared with children with ADHD alone,children with asthma and ADHD are more likely to show high levels of hyperactivity,hyperactive-impulsive and other externalizing behaviors and anxiety in clinical practice and have more symptoms of somatization and emotional internalization.AIM To explore the relationship between ADHD in children and bronchial asthma and to analyze its influencing factors.METHODS This retrospective cohort study was conducted at Dongying People's Hospital from September 2018 to August 2023.Children diagnosed with ADHD at this hospital were selected as the ADHD group,while healthy children without ADHD who underwent physical examinations during the same period served as the control group.Clinical and parental data were collected for all participating children,and multivariate logistic regression analysis was employed to identify risk factors for comorbid asthma in children with ADHD.RESULTSSignificant differences were detected between the ADHD group and the control group in terms of family history ofasthma and allergic diseases, maternal complications during pregnancy, maternal use of asthma and allergymedications during pregnancy, maternal anxiety and depression during pregnancy, and parental relationshipstatus (P < 0.05). Out of the 183 children in the ADHD group, 25 had comorbid asthma, resulting in a comorbidityrate of 13.66% (25/183), compared to the comorbidity rate of 2.91% (16/549) among the 549 children in the controlgroup. The difference in the asthma comorbidity rate between the two groups was statistically significant (P <0.05). The results of the multivariate logistic regression analysis indicated that family history of asthma and allergicdiseases, maternal complications during pregnancy, maternal use of asthma and allergy medications duringpregnancy, maternal anxiety and depression during pregnancy, and parental relationship status are independentrisk factors increasing the risk of comorbid asthma in children with ADHD (P < 0.05).CONCLUSIONChildren with ADHD were more likely to have comorbid asthma than healthy control children were. A familyhistory of asthma, adverse maternal factors during pregnancy, and parental relationship status were identified asrisk factors influencing the comorbidity of asthma in children with ADHD. Clinically, targeted interventions basedon these factors can be implemented to reduce the risk of comorbid asthma.

文摘The hypothesis that some children with attention-deficit hyperactivity disorder(ADHD)may show sensitivity or allergic reactions to various food items has led to the development of the the few-foods(or oligoantigenic)diet.The rationale of the diet is to eliminate certain foods from the diet in order to exclude potential allergens contained either naturally in food or in artificial ingredients with allergenic properties.The oligoantigenic diet attempts to identify individual foods to which a person might be sensitive.First,ADHD symptoms are monitored while multiple foods are excluded from the diet.Subsequently,if symptoms remit,foods are re-introduced,while observing the individual for the return of symptoms.An advantage of the oligoantigenic diet is that it can be tailored to the individual.A growing body of evidence suggests that behavioral symptoms of subgroups of children with ADHD may benefit from the elimination of certain foods.The effect sizes of an oligoantigenic diet regarding improvement of ADHD symptoms have been found to be medium to large.Available evidence suggests that the investigation of the role of food hypersensitivities in ADHD is a promising avenue worthy of further exploration.Further large-scale,randomized controlled studies including assessment of long-term outcome are therefore warranted.

文摘Attention-deficit hyperactivity disorder(ADHD) is a neurodevelopmental disorder prevalent in schoolage children. At present, however, its etiologies and risk factors are unknown. Transmembrane α-amino-3-hydroxy-5-methyl-4-isoxazolepropionicacid(AMPA) receptor regulatory protein γ-8(TARP γ-8,also known as calcium voltage-gated channel auxiliary subunit gamma 8(CACNG8)) is an auxiliary AMPA receptor(AMPAR) subunit. Here, we report an association between TARP γ-8 and ADHD,whereby adolescent TARP γ-8 knockout(KO) mice exhibitedADHD-likebehaviors,including hyperactivity, impulsivity, anxiety, impaired cognition,and memory deficits. Human single-nucleotide polymorphism(SNP) analysis also revealed strong associations between intronic alleles in CACNG8genes and ADHD susceptibility. In addition,synaptosomal proteomic analysis revealed dysfunction of the AMPA glutamate receptor complex in the hippocampi of TARP γ-8 KO mice.Proteomic analysis also revealed dysregulation of dopaminergic and glutamatergic transmissions in the prefrontal cortices of TARP γ-8 KO mice.Methylphenidate(MPH), which is commonly used to treat ADHD, significantly rescued the major behavioral deficits and abnormal synaptosomal proteins in TARP γ-8 KO mice. Notably, MPH significantly reversed the up-regulation of Grik2 and Slc6a3 in the prefrontal cortex. MPH also significantly improved synaptic AMPAR complex function by up-regulating other AMPAR auxiliary proteins in hippocampal synaptosomes. Taken together, our results suggest that TARP γ-8 is involved in the development of ADHD in humans.This study provides a useful alternative animal model with ADHD-like phenotypes related to TARP γ-8deficiency, which has great potential for the development of new therapies.
文摘The technique of region of interest-based positron emission tomography is limited by its poor reli-ability and relatively few examined brain regions. In the present study, we compared brain metabo-lism assessed using fluorine-18-fluorodeoxyglucose positron emission tomography between 14 at-tention-deficit hyperactivity disorder （ADHD） patients and 15 normal controls with scoliosis at resting state by statistical parametric mapping. Glucose metabolism was decreased in the left parahippo-campal gyrus, left hippocampus, left anterior cingulate gyrus, right anterior and posterior lobes of the cerebellum, left superior temporal gyrus, left insula, left medial and middle frontal gyri, right medial frontal gyrus, and left basal ganglia （putamen, amygdala, and caudate nucleus） in children with ADHD. These data suggest that children with ADHD exhibit hypometabolism in various brain regions compared to controls, indicating that ADHD symptoms are unlikely the result of abnormalities in specific areas.

文摘Background:To investigate the clinical medication approach of Professor Guiqi Xuan(Prof.Xuan)in treating pediatric patients with attention-deficit hyperactivity disorder(ADHD)and the potential mechanism of the core herbal prescription.Methods:Following medical record information pretreatment,the Traditional Chinese Medicine(TCM)inheritance computing platform system V3.0 was utilized to analyze the standardized data.The associate rules were summarized to identify the core prescription for treating ADHD.The extracted core herbal prescription’s active compounds and potential targets were used to establish a protein-protein interaction network of active ingredient-disease targets.Cytoscape 3.9.1 software was used to analyze the network’s topological parameters to obtain the key active ingredients and their targets.The Bioconductor data package of R4.0.2 was used to analyze the gene ontology biological functions and Kyoto Encyclopedia of Genes and Genomes pathways of key targets.Results:Two hundred and twenty-seven entries derived from TCM record information were selected.Through data mining,it was found that 62.5%of pediatric patients had short-tempered behavior,nearly half had sleep problems,and 30%-40%had picky eating and polyphagia issues.The highest-frequency syndrome type was kidney deficiency and liver hyperactivity.Deficiency,fire,phlegm,and dyspeptic food were the main pathological factors for ADHD.Prof.Xuan’s treatment of ADHD mainly focused on replenishing kidney essence and subduing Yang(active,external,ascending,warm,bright,functional and excited pertain to Yang).The core herbal prescription for ADHD included Yuan-zhi,Yi-zhi,Gui-jia,Bai-shao,Long-chi,Ci-shi,Shi-chang-pu,Yu-jin,Fu-shen,and Huang-jing.The protein-protein interaction network showed that MAOA,ADRB2,FOS,MAOB,and SLC6A3 were the five key targets essential in treating ADHD with core herbal prescriptions.The gene ontology biological function of crucial targets mainly involved G protein-coupled amine receptor activity,catecholamine binding,and neurotransmitter transmembrane transporter activity.Analysis of Kyoto Encyclopedia of Genes and Genomes pathways showed that the dopaminergic synapse signaling and neuroactive ligand-receptor interaction pathways were significantly enriched and may be the primary routes for the main treatment of ADHD.Conclusion:Prof.Xuan’s treatment of ADHD has achieved satisfactory clinical effects by supplementing the kidney,replenishing the essence,opening the orifices,nourishing the Yin(static,internal,descending,cold,dim,organic,depressed and pertain to Yin),and subduing the Yang.The major prescription predominantly affects catecholamine binding,neuroactive ligand-receptor interaction,G protein-coupled amine receptor function,and signaling pathways for dopaminergic synapses.Our findings showed that the methodology and software used in this research could explore and analyze the mechanism behind Prof.Xuan’s clinical medication rule for treating ADHD in children.
文摘Aims: To investigate rates of attention-deficit hyperactivity disorder (ADHD) in patients with chronic pain attending a pain clinic, the effects of a screening measure for ADHD in patients with chronic pain, and the effects of ADHD drugs on both pain and ADHD symptoms. Methods: We retrospectively surveyed 110 patients with chronic pain visiting the Anesthesiology and Pain Relief Center at the University of Tokyo in Japan, who had also consulted a psychiatrist, between April 2012 and July 2015. Results: Of the total of 110 patients with chronic pain, 35 (31.8%) were also diagnosed with ADHD, and the average Wender Utah Rating Scale (WURS) score among the ADHD patients was 39.0 ± 22.1 (n = 25). Only 36.0% of these patients exceeded the cutoff value, suggesting that 64.0% of the patients with ADHD were not identified by screening with the WURS. Twenty-six patients initiated treatment with ADHD medication, with dosage adjustment completed in 21. Of these 21 patients 20 (95.0%) had improved ADHD symptoms. Improved pain symptoms were observed in 14 patients (66.6%), with a reduction in the pain numerical rating scale of 64.7% ± 30.1%. Conclusions: This is the first study investigating the comorbidity of ADHD and chronic pain at pain clinics showing a high level of comorbidity and amelioration of pain and ADHD symptoms with treatment. Careful interpretation is required when the WURS is used to screen patients with chronic pain.

文摘Background Increased understanding of the etiology of attention-deficit hyperactivity disorder(ADHD)emphasizes the importance of non-pharmaceutical treatments.This study compares the effects of Baduanjin exercise,a Qigong-based body therapy from traditional Chinese medicine(TCM),with routine physical exercise on school-aged children diagnosed with ADHD.Methods In this two-arm,single-blind,randomized controlled trial,eligible school-aged children with ADHD were randomly assigned(1:1)to Baduanjin exercise or regular physical exercise using a permuted block randomization procedure.Both groups performed the designated exercise for at least 30 minutes a day and were monitored for exercise quality at least 5 days a week for 3 months.The primary outcome was a doctor-assessed hyperactivity/impulsivity score change,using the Swanson,Nolan,and Pelham rating scale(DSNAP_HYP)at the end of the third month since intervention initiation.Results Between October 2020 and January 2023,120 eligible children were randomly allocated to two exercise interventions.After 3 months,the DSNAP_HYP decreased by 3.67±4.81 and 4.68±4.44 of Baduanjin exercise and regular physical exercise,respectively,with no significant between-group difference[mean difference=1.52;95%confidence interval(CI)=−0.08 to 3.13;P=0.06].No adverse events were reported during the whole study period.Conclusions This study did not demonstrate the expected superiority of 3-month Baduanjin exercise in improving ADHD symptoms compared with routine physical exercise.However,the results suggest that both types of exercise may improve core symptom scores,providing preliminary evidence for Baduanjin as a potential supplementary intervention for children with ADHD.

文摘Sotos syndrome is characterized by overgrowth features and is caused by alterations in the nuclear receptor binding SET domain protein 1 gene.Attentiondeficit/hyperactivity disorder(ADHD)is considered a neurodevelopment and psychiatric disorder in childhood.Genetic characteristics and clinical presentation could play an important role in the diagnosis of Sotos syndrome and ADHD.Magnetic resonance imaging(MRI)has been used to assess medical images in Sotos syndrome and ADHD.The images process is considered to display in MRI while wavelet fusion has been used to integrate distinct images for achieving more complete information in single image in this editorial.In the future,genetic mechanisms and artificial intelligence related to medical images could be used in the clinical diagnosis of Sotos syndrome and ADHD.
文摘Attention-deficit/hyperactivity disorder(ADHD)is one of the most common neurodevelopmental disorders of childhood,yet its diagnosis remains complex and fraught with challenges.Pediatricians,often the first point of contact for concerned families,play a pivotal role in the diagnostic process.However,they face numerous obstacles that can hinder accurate and timely diagnosis,particularly in resource-limited or culturally diverse settings such as the Middle East and North Africa(MENA)and Arabian Gulf regions.This narrative review explores the key challenges pediatricians face in diagnosing ADHD and highlights practical and emerging solutions.The article offers both a global perspective and a contextualized view relevant to the MENA region.A narrative literature review was conducted using PubMed,Scopus,and Google Scholar,focusing on peer-reviewed studies,clinical guidelines,and epidemiological data from 2010 to 2025 related to pediatric ADHD diagnosis,especially in MENA regions.The review identifies six major diagnostic barriers:(1)Symptom overlap with other conditions[e.g.,autism spectrum disorder(ASD),anxiety,learning disabilities];(2)Reliance on subjective informant reports;(3)Cultural and societal influences including stigma and gender bias;(4)Variability in ADHD training and time constraints in clinical practice;(5)Limited access to multidisciplinary evaluations;and(6)Systemic referral and communication inefficiencies.Comorbidities are highly prevalent and frequently complicate the diagnostic picture.Delayed or inaccurate diagnosis can lead to academic underperformance,family stress,missed interventions,and long-term psychological consequences.Emerging solutions include digital screening tools,artificial intelligence-assisted analysis,structured reporting platforms,and improved training and referral models.Regional data from the Arabian Gulf highlight variable prevalence rates(1.3%-22%)and underscore the need for culturally sensitive diagnostic strategies.To improve diagnostic accuracy and patient outcomes,pediatricians must be supported through better training,interdisciplinary collaboration,validated tools,and policy-level reforms.Tailoring these approaches to local contexts will be key to addressing the growing burden of ADHD,particularly in the MENA region.

文摘Attention-deficit/hyperactivity disorder(ADHD)is increasingly conceptualized as a dynamic neurodevelopmental condition,marked by fluctuating symptom trajectories across development rather than the traditional static patterns of persistence or remission.This review synthesizes empirical evidence on the varied trajectories of ADHD symptoms-including late-onset,partial remission,and recurrent fluctuation patterns-and underscores their clinical significance in longterm functioning.We adopt a multifactorial framework to explore how genetic,environmental,and gene–environment interactions contribute to the emergence and evolution of ADHD symptoms over time.In addition,we consider how medication-related variables-particularly tolerance and adherence-may influence symptom fluctuation.Characterizing these developmental dynamics offers critical guidance for designing flexible,personalized interventions that align with individual trajectories and transitional vulnerabilities.

文摘Background Attention-deficit/hyperactivity disorder(ADHD)is a common neurodevelopmental disorder with behavioural symptoms and grey matter volume(GMV)changes.However,previous studies have not fully elucidated the progressive and causal GMV changes associated with behavioural symptoms in ADHD.Aims This study aimed to explore the causal relationship between GMV alterations and behavioural symptoms in children and adolescents with ADHD using behaviourcausal structural covariance network(BCaSCN)analysis.Methods Structural magnetic resonance imaging(sMRI)data from 135 children and adolescents with ADHD and182 neurotypical controls(NCs)were analysed.ADHD subtypes were identified based on GMV using a clustering algorithm to address the neuroanatomical heterogeneity.To investigate the causal relationships of GMV changes related to behavioural symptoms,sMRI data were sequentially ordered by ADHD index,inattentive index and hyperactive/impulsive index values to generate pseudotime series data.These data were then analysed using region-of-interest-based BCaSCN analysis to explore potential progressive patterns of GMV change.Results Neuroanatomical subtyping revealed two ADHD subtypes with distinct GMV patterns compared with NCs.BCaSCN analysis showed that ADHD subtype 1 was closely associated with inattentiveness,involving prominent nodes in the frontal regions and cerebellum.In contrast,ADHD subtype 2 was more strongly linked to overall disease severity,with the cerebellum and hippocampus as primary hubs.Conclusions ADHD is associated with heterogeneous changes in GMV corresponding to distinct behavioural domains,highlighting the need for subtype-specific diagnostic and therapeutic strategies.
文摘Deficiencies of nutrients,including vitamins,minerals and polyunsaturated fatty acids,and surpluses of food items,such as sucrose and artificial food additives,have not convincingly been shown to be involved in the etiology of ADHD.At group level,there is no conclusive evidence supporting dietary interventions for the treatment of ADHD.The identification of a role of food compounds in ADHD is hindered by the complex and ill-defined nature of ADHD.In view of the heterogeneity of the disorder,potential therapeutic benefits of nutritional interventions could be confined to subpopulations of children with ADHD as yet unidentified.The cumulative benefits of the range of ingredients comprising healthy diets may result in better outcomes compared to a supplementation of individual nutrients.Diet and nutrition interact with other lifestyle factors,such as physical activity,and the interrelationship between nutrition and lifestyle should play a more prominent role in research on treatment approaches to ADHD.The few-foods or oligoallergenic diet allows the design of individually tailored diets and may offer treatment opportunities in subgroups of children diagnosed with ADHD.Further research is required to demonstrate the utility of nutrition-related interventions alone or in combination with other treatment approaches in ADHD.
文摘Background： Attention-deficit hyperactivity disorder （ADHD） is the most common mental and behavioral disorder in school-aged children. This study evaluated the effect of osmotic-release oral system （OROS） methylphenidate （MPH） on cognitive function and academic performance of Chinese school-aged children with ADHD. Methods： This 12-week, prospective, multicenter, open-label, self-controlled study enrolled 153 Chinese school-aged children with ADHD and 41 non-ADHD children. Children with ADHD were treated with once-daily OROS-MPH （18 mg, 36 mg, or 54 mg）. The primary endpoints were Inattention/Overactivity （I/O） with Aggression Conners Behavior Rating Scale （IOWA） and Digit Span Test at week 12 compared with baseline. Secondary endpoints included opposition/defiant （O/D） subscale of IOWA, Clinical Global Impression （CGI）, Coding Test, Stroop Color-word Test, Wisconsin Card Sorting Test （WCST）, academic performance on teacher-rated school examinations, and safety at week 12 compared with baseline. Both non-ADHD and ADHD children received the same frequency of cognitive operational test to avoid the possible bias caused by training. Results： A total of 128 patients were evaluated with cognitive assessments. The OROS-MPH treatment significantly improved IOWA Conners I/O subscale scores at week 12 （3.8 ± 2.3） versus baseline （10.0 ± 2.4; P 〈 0.0001）. Digit Span Test scores improved significantly （P 〈 0.0001 ） with a high remission rate （81.1%） at week 12 versus baseline. A significant （P 〈 0.0001 ） improvement was observed in O/D subscale of IOWA, CGI, Coding Test, Stroop Color-word Test, WCST, and academic performance at week 12 versus baseline. Very few practice-related improvements were noticed in the non-ADHD group at week 12 compared with baseline. No serious adverse events and deaths were reported during the study. Conclusions： The OROS-MPH treatment effectively controlled symptoms of ADHD and significantly improved academic performance and cognitive fimction of Chinese school-aged children with ADHD. The treatment was found to be sate and generally well-tolerated over 12 weeks.
文摘Sleep disturbances and disorders are commonly associated with attention-deficit/hyperactivity disorder(ADHD),with affected children frequently experiencing delayed sleep onset,frequent nighttime awakenings,morning fatigue,and excessive daytime sleepiness.A bidirectional relationship exists between ADHD and sleep disturbances:Sleep deprivation is linked to increased inattention and emotional dysregulation,while evening hyperactivity and impulsivity may contribute to difficulty falling asleep.Central nervous system stimulants remain the first-line treatment for managing ADHD symptoms;however,insomnia can be a common side effect.Notably,newer and long-acting stimulants formulations have demonstrated extended benefit into evening with limited impact on sleep in recent studies.This narrative review summarizes the various sleep disorders associated with ADHD,outlines clinical approaches for sleep assessment,and evaluates the impact of ADHD treatments on sleep.It also highlights both nonpharmacological and pharmacological interventions for managing sleep problems in children with ADHD.Finally,the review offers practical recommendations to help clinicians optimize both sleep and daytime functioning in patients with ADHD.ADHD should be conceptualized as a 24-hour disorder,requiring integrated treatment strategies that address both daytime symptoms and nighttime sleep challenges.

文摘Attention deficit hyperactivity disorder(ADHD)turns into a common neuro progressional disorder.Although gender identity has obtained increasing attention in ADHD researches,its role in ADHD presentation and treatment response remains underexplored.Our review seeks to mainly delve into the effect of gender identity on ADHD,exploring the unique needs of individuals with various gender identities in the context of ADHD symptoms,diagnostic assessment,and treatment,with the goal of supplying theoretical support and practical recommendations for future research and clinical practice.The primary content includes,specifically:(1)Symptom expression differences:Gender identity significantly affects ADHD symptoms;male-identified individuals commonly perform worse in task orientation and attention stability,while female-identified individuals may demonstrate more variability in attention control and executive functions;(2)Diagnosis and treatment:Clinical practice generally neglects the impact of gender identity on ADHD management,with personalized needs of gender-identified individuals frequently not adequately addressed,potentially,affecting treatment outcomes;and(3)Future research directions:Future studies should further assess how gender identity affects the specific mechanisms of ADHD,conduct researches in multicultural contexts,and engage in long-term follow-up studies to evaluate the long-term impact of gender identity on ADHD progression.Besides,enhanced funding and public education on the relationship between gender identity and ADHD are needed to advance the field.
文摘BACKGROUND Speech and language therapy(ST)might moderate the prognosis in children with attention deficit and hyperactivity disorder(ADHD)comorbid with speech delay.This study investigated whether ST in children with ADHD is associated with a decreased risk of subsequent psychiatric disorders.AIM To investigate whether ST in children with ADHD is associated with a decreased risk of subsequent psychiatric disorders.METHODS The population-based National Health Insurance Research Database in Taiwan was used.Hazards of subsequent psychiatric disorders were compared between those who received ST and a propensity-score matched comparison group by Cox regression analyses.RESULTS Of 11987 children with ADHD identified from the dataset,2911(24%)had received ST.The adjusted hazard ratio for any subsequent recorded psychiatric disorder was 0.72(95%confidence interval:0.63-0.82)in children who received ST compared to the matched counterparts.This protective association was only statistically significant in the subgroup that received both medication and behavioral interventions.CONCLUSION ST can moderate the effects of integrated early interventions in ADHD children with speech delay.
