Abordaje de los trastornos del sueño en los trastornos del neurodesarrollo / Treatment of sleep disorders in neurodevelopmental disorders

Resumen Los trastornos del sueño son frecuentes en niños y afectan al desarrollo neurológico, con importante repercusión cognitiva, emocional y conductual. Existe una alta prevalencia de trastornos del sueño (TS) en los trastornos del neurodesarrollo (TND), como trastorno del espectro autista (TEA) y trastorno por déficit de atención con hiperactividad (TDAH). Los TS en población pediá trica tienen una prevalencia del 6-25%, mientras que en los niños con TND esta cifra asciende al 50-80%. En los TND se observa un incremento de las dificultades para conciliar el sueño, de los despertares nocturnos y de la somnolencia diurna. Así mismo, presentan alteracio nes del ritmo circadiano y trastornos respiratorios del sueño. Como consecuencia se produce una reducción de la alerta para las actividades diarias con incremento de trastornos conductuales, problemas emocionales y dificultades académicas asociadas a disfunciones eje cutivas y de memoria. La evaluación del sueño debe formar parte sistemática en la valoración clínica de los niños con TND, con el fin de realizar un diagnóstico y un tratamiento adecuados a cada caso, permitiendo mejorar la calidad de vida del niño y de su familia.

Abstract Sleep disorders are common in children and affect neurological development with important cognitive, emotional and behavioral repercussions. There is a high prevalence of sleep disorders (SD) in neurodevelop mental disorders (NDD) such as autism spectrum dis order (ASD) and attention-deficit hyperactivity disorder (ADHD). Sleep disorders in pediatric population have a prevalence of 6-25%, while in children with NDD this number rises to 50-80%. In NDDs, higher rates of dif ficulties in falling asleep, nocturnal awakenings and daytime sleepiness are observed. Disturbances in the circadian rhythm as well as respiratory sleep disorders are also observed. Consequently, there is a decrease in alertness for daytime activities with increased be havioral disorders, emotional problems and academic difficulties associated with executive and memory dys functions. Sleep assessment has to be a systemic part in the clinical evaluation of children with NDDs, so as to give a convenient diagnosis and treatment in each case, allowing to improve the quality of life of children and their families.

Trastorno por Déficit de Atención/Hiperactividad (TDAH) y Trastorno de Tourette (TT): entre la comorbilidad y el diagnóstico diferencial / Attention deficit/hyperactivity disorder (ADHD) and To urette disorder (TD): between comorbidity and differential diagnosis

Resumen El Trastorno de Tourette (TT) y el Trastorno por déficit de atención / hiperactividad (TDAH) son entidades neu ropsiquiátricas que usualmente inician en la infancia. Esta revisión busca colaborar con los clínicos, quienes suelen confrontarse al dilema de saber si existe una comorbilidad o un diagnóstico diferencial, ya que esta pregunta cobra vital importancia en el momento de decidir el tratamiento. Invitamos al colega a revisar nuestros hallazgos, soportados por bases moleculares, fisiológicas y neuroanatómicas, además de los datos epidemiológicos. Al final, brindamos una propuesta de algoritmo diag nóstico que podrá utilizar cuando se encuentre ante síntomas compartidos entre los dos diagnósticos. El TDAH y el TT deben ser intervenidos tempranamente, para mejorar la calidad de vida y funcionalidad del paciente y prevenir secuelas, no solo en niños, niñas y adolescentes (NNA), también a lo largo de la vida.

Abstract Tourette Disorder (TD) and attention deficit hyperac tivity disorder (ADHD) are both major neuropsychiatric conditions that usually begin during infancy. This revision aims to collaborate with pediatricians, who are often confronted with the question of co-mor bidity or differential diagnosis between ADHD and TD. The question becomes urgent when the clinician must decide if he/she can start ADHD or TD treatment. We encourage our colleagues to revise our findings, based in bimolecular and neuroanatomic shared issues in ad dition to updated epidemiological findings. The clinician will find an original proposed algorithm that they can use when the shared symptoms are pres ent in a little patient. TD and ADHD must be intervened early, so we can get better outcomes. The consequences of letting the symptoms increase can generate sequels and handicaps, that can interfere with the quality of life and functionality not only during infancy and adoles cence but also in adult life.

Genética del TDAH en la práctica clínica / Genetics of ADHD in clinical practice

Resumen El trastorno por déficit de atención/hiperactividad (TDAH) es un trastorno del neurodesarrollo complejo y heterogéneo desde una perspectiva causal, clínica y pro nóstica. La investigación refleja su carácter multifactorial con un papel destacado de los factores genéticos. Los estudios poblacionales han señalado históricamente la implicación de numerosas variantes genéticas de escaso tamaño de efecto, las cuales por sí mismas apenas incre mentan el riesgo de TDAH y difícilmente justifican su ele vada heredabilidad. Muchas de ellas están presentes en más del 60% de la población general, lo que sugiere su pa pel modulador más que causal. No obstante, gracias a la irrupción de nuevas técnicas genéticas en los últimos 15 años, se están identificando un mayor número de casos con trastornos genéticos (muchos de ellos monogénicos), cuyas variantes genéticas explican por sí mismas la presencia del TDAH. El estudio detallado de los antecedentes personales y familiares, así como una exploración física completa, puede ayudar a identificar algunos de ellos. La identificación de la causa en este conjunto de casos tiene un valor crucial en el asesoramiento clínico, el consejo genético-familiar y la anticipación pronóstica, así como en la realización o evitación de estudios complementarios y en el diseño del plan terapéutico.

Abstract Attention-deficit/hyperactivity disorder (ADHD) is a complex and heterogeneous neurodevelopmental disor der from a causal, clinical and prognostic perspective. Research reflects its multifactorial nature with a promi nent role of genetic factors. Population studies have historically pointed to the involvement of numerous genetic variants of small effect size, which hardly by themselves increase the risk of presenting the disorder and hardly justify its high heritability. Many of them are present in more than 60% of the general population, suggesting their modulatory rather than causal role. However, after the irruption of new genetic techniques in the last 15 years, a greater number of cases are be ing identified with genetic disorders (many of them monogenic), whose genetic variants alone explain the presence of ADHD. A detailed study of the personal and family history, as well as a complete physical examination, can help to identify some of them. The identification of the cause in this group of cases has a crucial value in clinical counseling, genetic-familial counseling and prognostic anticipation, as well as in the performance or avoidance of complementary stud ies and in the design of the intervention plan.

Translation, cross-cultural adaptation and validation of the Short Screening Instrument for Psychological Problems in Enuresis for use in Brazil (SSIPPE-Br)

Abstract Objective: Enuresis is associated with attentional and emotional comorbidities in 20 to 30 % of cases. The Short Screening Instrument for Psychological Problems in Enuresis (SSIPPE) is a questionnaire that allows the initial screening of these comorbidities. This study aimed to translate, culturally adapt, and validate the SSIPPE for Brazilian children and adolescents (SSIPPE-Br). Methods: Six steps were performed for translation and cross-cultural adaptation: translation, synthesis of translations, back-translation, preparation of the pre-final version of the translated instrument, test of comprehensibility of the pre-final version of the tool, and elaboration of the instrument cross-culturally adapted for Brazil, named 13-itens version SSIPPE-Br. To validate the SSIPPE-Br, a cross-sectional study was carried out, in which the validated Brazilian version of the Child and Adolescent Behavior Inventory (CABI) was used. Results: Validation was performed on 127 children and adolescents with a mean age of 9.7 ± 2.8 years, 48 % male. The reliability was estimated using Cronbach's alpha, ranging from 0.86 to 0.89, indicating good internal consistency. The factorial analysis had a good agreement adjustment (KMO 0.755, Bartlett's test < 0.001) and explained 70.5 % of the data variability. In the reproducibility analysis, the Kappa coefficient ranged from 0.94 to 1, which can be considered almost perfect. A highly significant (p-value < 0.001) and direct correlation existed between the three SSIPPE-Br domains and all evaluated CABI domains. Conclusion: The SSIPPE-Br is a valid and reliable tool for emotional problems screening and ADHD symptoms in children and adolescents with enuresis whose first language is Brazilian Portuguese.

Deterioro funcional y neurocognitivo en pacientes con esquizofrenia deficitaria en Perú y confiabilidad de la estructura bidimensional de la sintomatología negativa / Functional and neurocognitive impairment in deficit schizophrenia patients in Peru and reliability of the bidimensional structure of negative symptomatology

Resumen La mayoría de los estudios sugieren que los pacientes con esquizofrenia deficitaria presentan un deterioro funcional y neurocognitivo más grave en comparación con los pacientes con esquizofrenia no deficitaria. Sin embargo, existen pocos estudios al respecto en América Latina. Examinar las diferencias entre el funcionamiento y el deterioro neurocognitivo en pacientes con y sin esquizofrenia deficitaria; y analizar la validez de la estructura bifactorial de los síntomas negativos en una muestra de pacientes peruanos. Se reclutó a un total de 53 pacientes peruanos con esquizofrenia. Se utilizó la versión en español del Schedule for the Deficit Syndrome (SDS) para diagnosticar el síndrome deficitario, el Functioning Assessment Short Test (FAST) para evaluar el funcionamiento global, y el Screen for Cognitive Impairment in Psychiatry (SCIP) para evaluar el funcionamiento neurocognitivo. La prevalencia de esquizofrenia deficitaria fue del 62,3 %. Los pacientes con esquizofrenia deficitaria presentan un mayor deterioro en la memoria de trabajo (p = 0,003), fluidez verbal (p = 0,002), aprendizaje verbal retardado (p = 0,039) y velocidad de procesamiento (p = 0,004). En cuanto al funcionamiento global, los pacientes con esquizofrenia deficitaria muestran un rendimiento inferior en las dimensiones de autonomía (p = 0,002), laboral (p = 0,001), cognitiva (p = 0,010), finanzas (p = 0,015), relaciones interpersonales (p < 0,001) y tiempo de ocio (p < 0,001). Los pacientes con esquizofrenia deficitaria muestran un mayor deterioro en el funcionamiento global y cognitivo. La replicación de la estructura bidimensional de los síntomas negativos en una muestra peruana contribuye a la hipótesis de la universalidad del modelo de «déficit expresivo¼ y «apatía-abulia¼.

ABSTRACT Many studies suggest that patients with deficit schizophrenia exhibit a more severe functional and neurocognitive impairment than those with non-deficit schizophrenia. However, there are few studies on this topic in Latin America. To examine the differences in functioning and neurocognitive impairment between patients with and without deficit schizophrenia, and to analyze the validity of the bifactorial structure of negative symptoms in a sample of Peruvian patients. A total of 53 Peruvian patients with schizophrenia were recruited. The Spanish version of the Schedule for the Deficit Syndrome (SDS) was used to diagnose the syndrome under study. The Functioning Assessment Short Test (FAST) was employed to assess global functioning, and the Screen for Cognitive Impairment in Psychiatry (SCIP), to evaluate neurocognitive functioning. The prevalence of deficit schizophrenia was 62.3%. Patients with deficit schizophrenia exhibited greater impairment in working memory (p = 0.003), verbal fluency (p = 0.002), delayed verbal learning (p = 0.039), and processing speed (p = 0.004). Regarding global functioning, patients with deficit schizophrenia demonstrated poorer performance in the domains of autonomy (p = 0.002), occupational functioning (p = 0.001), cognitive functioning (p = 0.010), financial functioning (p = 0.015), interpersonal relationships (p < 0.001), and leisure time (p < 0.001). Patients with deficit schizophrenia display greater impairment in global and cognitive functioning. The replication of the bidimensional structure of negative symptoms in a Peruvian sample contributes to the hypothesis of the universality of the "expressive deficit" and "apathy-abulia" model.

Application of transcranial sonography in the assessment of substantia nigra echo in children with attention deficit hyperactivity disorder / 中华超声影像学杂志

Objective:To determine the clinical application value of transcranial sonography (TCS) in the diagnosis of attention deficit hyperactivity disorder (ADHD) in children.Methods:A total of 50 children aged 6-12 years diagnosed with ADHD (ADHD group) and 45 age-matched healthy children (control group) who presented to Suzhou Municipal Hospital and Children′s Hospital of Soochow University from August 2021 to August 2022 were prospectively enrolled for TCS examination. ADHD was diagnosed in accordance with the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-Ⅴ) criteria established by the American Psychiatric Association.Based on clinical symptom characteristics, ADHD was further classified into 3 subtypes, including 14 cases of predominantly inattentive, 3 cases of predominantly hyperactive/impulsive, and 33 cases of combined presentation. The substantia nigra(SN) hyperechoic area and the ratio of SN hyperechoic area to midbrain area (S/M) were measured and compared between the two groups. The examination of the correlation was performed between SN hyperechoic area, S/M ratio, and DSM-Ⅴ scores within the ADHD group.Results:Semi-quantitative analysis: the proportion of the SN grade Ⅲ or more in ADHD group was significantly higher than that in control group [96.00%(48/50) vs 13.3%(6/45), P<0.05]. Quantitative analysis: the area of SN hyperechogenicity and the ratio of S/M were significantly larger in ADHD group than in control group [0.32(0.22, 0.38)cm 2 vs 0.00(0.00, 0.00)cm 2, 7.08(5.11, 8.75)% vs 0.00(0.00, 0.00)%, all P<0.05]. Correlation analysis: The SN hyperechoic area and S/M ratio showed no significant correlations with DSM-Ⅴ scores in the ADHD group ( r=0.144, 0.142, all P>0.05). Conclusions:TCS can detect the SN echo enhancement of ADHD children, and the proportion of SN echo enhancement, SN hyperechoic area and S/M ratio are significantly higher than those of normal children, but the SN hyperecho area and S/M ratio are not significantly correlated with DSM-Ⅴ scores.

Influencing factors of attention deficit hyperactivity disorder and the correlation between bone mineral density and physical growth in children / 中国儿童保健杂志

【Objective】 To analyze the contributing factors of attention deficit hyperactivity disorder (ADHD) in children and the correlation between bone mineral density and physical growth, in order to provide new clues for the prevention and early intervention of ADHD. 【Methods】 A total of 116 children with ADHD were included into the observation group from June 2020 to June 2022, while another 80 healthy children in the same period were included as the control group.Clinical data of the two groups were compared, and the factors influencing ADHD in children were analyzed using multivariate Logistic regression. Children with ADHD were further divided into boys group and girls group based on gender. Bone mineral density (BMD) and physical growth (height and body weight) of the two groups were measured, and the correlation between the two was analyzed. 【Results】 In the observation group, the proportion of boys, maternal bad behaviors during pregnancy, their educational level below high school, critical parenting, and parental stress index were significantly higher compared to the control group (χ2=14.430, 5.689, 5.630, 6.738, t=6.936, P<0.05). Additionally, family environment score was significantly lower than that in the control group (t=6.328, P<0.05). Logistic regression analysis revealed that factors including boys (OR=3.298, 95%CI: 1.759 - 6.184), maternal bad behaviors during pregnancy (OR=2.730, 95%CI: 1.169 - 6.375), maternal education level of senior high school or below (OR=2.032, 95%CI: 1.127 - 3.663), critical parenting (OR=2.349, 95%CI: 1.223 - 4.513), and parental stress index (OR=1.089, 95%CI: 1.055 - 1.124) were positively correlated with ADHD in children (P<0.05), while family environment score was negatively related to ADHD (OR=0.868, 95%CI: 0.820 - 0.919, P<0.05). There were no significant differences in BMD, height and body weight between boys and girls in ADHD group (P>0.05). Pearson correlation analysis indicated a positive correlation of BMD with height and body weight (r=0.409, 0.317, P<0.05). 【Conclusions】 The development of ADHD in children is associated with gender, maternal bad behavior during pregnancy, family parental style and so on. Bone mineral density is closely related to physical growth in children with ADHD, clinical interventions can be implemented to prevent or early intervene ADHD.

Pharmacogenetic impact on the methylphenidate-hydrocloride treatment in children with attention-deficit hyperactivity disorder / 中国儿童保健杂志

Attention-deficit hyperactivity disorder (ADHD) is one of the most common chronic neurodevelopmental disorders in childhood.It is mainly manifested as inattention, hyperactivity, and impulsivity that are inconsistent with the development level, which may lead to multiple functional impairments and place heavy burdens on individuals, families, and society.Methylphenidate hydrochloride (MPH) is a first-line treatment drug for ADHD, which is widely used in clinical practice.However, some patients have no response to drug treatment and adverse reactions often cause premature termination of treatment.Introducing the concept of pharmacogenetics into MPH treatment may open new avenues for individualized interventions of ADHD.This paper aims to review the impact of pharmacogenetics on MPH treatment in children with ADHD and to provide references for clinical drug treatment and management.

Status quo and its influencing factors of social anxiety in school-age children with attention deficit hyperactivity disorder / 中国儿童保健杂志

【Objective】 To investigate the current situation of social anxiety in children with attention deficit hyperactivity disorder (ADHD), and to analyze the factors influencing social anxiety in ADHD children, in order to provide reference for improving the clinical management of ADHD children. 【Methods】 A total of 206 school-age children with ADHD were selected from the Children′s Psychology Clinic of Mianyang Central Hospital from January 2020 to January 2023. The relevant clinical data of the children were collected through the general data questionnaire. Children′s Social Anxiety Scale (SASC) was used to assess social anxiety, and the Social Response Scale (SRS) was used to assess social ability. The Chinese version of Swanson,Nolan and Pelham Rating Scale Ⅳ (SNAP-Ⅳ) was used to assess core symptoms. Multivariate Logistic regression analysis was used to determine influencing factors of social anxiety in children with ADHD. 【Results】 There were 128(62.14%) cases detected with social anxiety among 206 children with ADHD. The score of SASC was 14.02±4.06. The proportions of girls (χ2=6.057), comorbid autism spectrum disorder(ASD) (χ2=4.929), and main caregivers with junior high school education or below (χ2=13.345), the total score of SRS(t=5.842) and SNAP-Ⅳ(t=7.848) and the scores of all dimensions were significantly higher than those in the non-anxious group (P<0.05). Multivariate Logistic regression analysis showed that higher SRS total score(OR=5.217, 95%CI: 2.309 - 11.791), higher SNAP-Ⅳ total score(OR=4.150, 95%CI: 1.974 - 8.722), girls(OR=2.268, 95%CI: 1.423 - 3.616), primary caregivers with junior high school education or below (OR=1.527, 95%CI: 1.162 - 2.005), and comorbid ASD (OR=1.551, 95%CI: 1.209 - 1.990) were risk factors for social anxiety in ADHD children (P<0.05). 【Conclusions】 Children with ADHD have a higher prevalence rate of social anxiety. Cognitive behavioral therapy and psychological intervention should be strengthened for high-risk children to improve social ability and reduce the risk of social anxiety.

Treating Attention Deficit Hyperactivity Disorder from the Lung Based on Circular Movement and Five Spirits Stored in Corresponding Viscera Theory / 中医杂志

It is believed that the main pathogenesis of attention deficit hyperactivity disorder （ADHD） is the abnormality of the ethereal and corporeal soul that dominate perception， behaviour and sensory functions， that is， the left liver ethereal soul ascending too much while the right lung corporeal soul failing to descend， of which lung corporeal soul restlessness and lung failing to astringe and descend is the core. By analyzing the pathogenesis of attention defects due to “heart-lung-kidney-liver four dimensions circuit failure” and hyperactivity and impulsivity due to “liver-heart-lung chief and deputy disharmony” from the perspective of circular movement and five spirits stored in corresponding viscera theory， respectively， it is believed that the lung corporeal soul plays an important role in the onset of this disease， and further summarized that “the five zang （脏） organs are correlated， and the lungs are the pivot” is the pathogenic characteristics， and “the lung corporeal soul is restless， and the lungs fail to astringe and descend” is the core pathogenesis. It is proposed that deficiencies can be treated with self-made Jingning Formula （静宁方） modification to supplement the lungs， calm the corporeal soul， and nourish the source of yin.

ObjectiveTo investigate the developmental characteristics of gross motor skills and executive functions, and the correlation between them in school-age children with attention deficit hyperactivity disorder (ADHD). MethodsFrom November, 2020 to May, 2021, 90 children with ADHD were recruited from Peking University Sixth Hospital and Beijing Haidian Wanquan Primary School, and other 90 children with normal development from this primary school were recruited matched their age and gender. Gross motor skills were assessed with the Test of Gross Motor Development in Children, Third Edition (TGMD-3), and inhibitory control, working memory, and cognitive flexibility were assessed with Stroop Color Words Test (SCWT), Rey-Osterrich Complex Figure Test (ROCFT) and Trail Making Test (TMT), respectively. ResultsThe TGMD-3 score was significantly lower in children with ADHD than in normal children (t = -6.275, P < 0.001), while the test results of SCWT, ROCFT and TMT were worse (|t| ≥ 1.986, P ≤ 0.05). The TGMD-3 score of children with ADHD was negatively correlated with the word sense reaction time (r = -0.261), the number of word sense errors (r = -0.404) and the number of color errors (r = -0.326) (P < 0.05), positively correlated with the delayed structural memory scores (r = 0.228) (P < 0.05), and negatively correlated with the TMT-A reaction time (r = -0.255), the number of TMT-A errors (r = -0.329), TMT-B reaction time (r = -0.214) and the number of TMT-B errors (r = -0.474) (P < 0.05). Stratified linear regression analyses showed that the TGMD-3 score of children with ADHD was significant only in predicting test results for inhibitory control and cognitive flexibility (P < 0.05), with explanations of 8.7% and 22.5%, respectively. ConclusionDevelopments of both gross motor skills and executive function delay in children with ADHD, and there is a relation between them, especially the level of gross motor skills relating to the developments of inhibitory control and cognitive flexibility.

Tectorigenin improves cognitive deficits in rats with vascular dementia by regulating TLR4/MyD88/NF-κB signaling pathway / 中国免疫学杂志

Objective:To analyze effects of tectorigenin on improving cognitive deficits in rats with vascular dementia(VD)by regulating Toll-like receptor 4(TLR4)/myeloid differentiation factor 88(MyD88)/nuclear factor-κB(NF-κB)signaling pathway.Methods:A total of 72 rats were randomly divided into sham operation group,model group,low,medium and high doses[25,50,100 mg/(kg·d)]tectorigenin groups and positive control group[piracetam 324 mg/(kg·d)],with 12 rats in each group.Except for sham operation group,VD models were replicated in other groups.After successful modeling,different doses tectorigenin groups and positive control group were administered intragastrically with different doses of tectorigenin and piracetam,while other groups were administered intragastrically with same volume of normal saline for 28 d.Spatial learning and memory ability were detected by Morris water maze.Neurotransmitter levels in hippocampus interstitial fluid were detected by high performance liquid chromatography-electro-chemical.Brain-derived neurotrophic factor(BDNF)and tyrosine kinase receptor b(TrkB)expressions in hippocampus were detected by RT-qPCR and Western blot.TLR4/MyD88/NF-κB pathway-related proteins in hippocampus were detected by Western blot.Results:Compared with sham operation group,escape latency was longer,while stay time in target area and times of crossing platform were lower in model group(P<0.05).Compared with model group,escape latency was shorter,while stay time in target area and times of crossing platform were higher in medium and high doses tectorigenin groups(P<0.05).NE,DA,5-HT and 5-HIAA levels in model group were lower than those in sham operation group(P<0.05),which were higher in medium and high doses tectorigenin groups than model group(P<0.05).Compared with sham operation group,BDNF and TrkB mRNA and proteins levels were lower,while TLR4,MyD88 and p-NF-κB p65/NF-κB p65 proteins levels were higher in model group(P<0.05).Compared with model group,BDNF and TrkB mRNA and proteins levels were higher,while TLR4,MyD88 and p-NF-κB p65/NF-κB p65 proteins levels were lower in medium and high doses tectorigenin groups(P<0.05).Conclusion:Tectorigenin can improve cognitive deficits in VD rats,which may be related to regulating TLR4/MyD88/NF-κB signaling pathway.

Characteristics of brain cortical morphology in children with attention deficit hyperactivity disorder co-occurred with oppositional defiant disorder / 中国心理卫生杂志

Objective:To investigate the characteristics of cortical morphology in children with attention defi-cit hyperactivity disorder(ADHD)and those with oppositional defiant disorder(ODD)from both categorical and dimensional analyses.Methods:A total of 72 children were enrolled,including 16 children with ADHD and ODD,20 children with ADHD without ODD,and 36 age-gender-matched normal children.The diagnoses were made ac-cording to the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)criteria.The Chi-nese Wechsler Intelligence Scale for Children(C-WISC)was used to access intelligence quotient.All subjects par-ticipated in the magnetic resonance imaging(MRI)scan.The features of cortical morphology were determined using FreeSurfer software.Results:Children with ADHD and ODD[(6 528.1±857.5)mm3 vs.(7 591.2±657.3)]and children with ADHD only[(6 867.2±41.3)mm3 vs.(7 591.2±657.3)mm3]had smaller volume in the left later-al superior temporal gyrus(P＜0.05)than controls.No difference was found between ADHD with ODD group and ADHD without ODD group.There was no correlation between the cortical volume of left lateral superior temporal gyrus and ODD symptoms.Conclusion:The reduced cortical volume of left lateral superior temporal gyrus may be an important indication of the abnormal brain structure of ADHD in children.And comorbid status of ODD dose not change this structural variation.

Effects of cortisol-awakening response on multi-target tracking in children with attention deficit hyperactivity disorder: the mediating role of working memory / 中华行为医学与脑科学杂志

Objective:To explore the mediating role of working memory (WM) in the cortisol-awakening response (CAR) and multiple object tracking (MOT) in children with attention deficit hyperactivity disorder (ADHD).Methods:92 children with ADHD (ADHD group) and 94 typically developing children (control group) were selected from January 2022 to October 2022. Salivary cortisol levels were detected and analyzed in all children at four time points after awakening. Children's WM and MOT performance were assessed by the 1-back and MOT paradigms, respectively. SPSS 26.0 software was used for t-test and Pearson correlation analysis of the data, and plug-in PROCESS model 4 of SPSS 26.0 was used for mediated effects analysis. Results:(1) ADHD group showed significantly lower CAR, 1-back accuracy and MOT performance((30.97±5.63), (81.33±10.64) %, (2.36±0.37)) than the control group((32.41±3.48), (91.19±7.12) %, (2.62±0.28))( t=-2.09, -7.22, -5.31, all P<0.05). (2) Pearson analysis showed that CAR was positively correlated with 1-back accuracy ( r=0.293, P<0.01) and MOT performance ( r=0.740, P<0.01). 1-back accuracy was positively correlated with MOT performance ( r=0.368, P<0.01). (3) WM partially mediated the effect of CAR on MOT in children with ADHD, accounting for 6.13% (0.003/0.049) of the total effect. Conclusion:Children with ADHD have deficits in MOT.WM plays a mediating role between CAR and MOT performance in children with ADHD.
