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

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 neurodevelopmental disorders (NDD) such as autism spectrum disorder (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 difficulties 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 behavioral disorders, emotional problems and academic difficulties associated with executive and memory dysfunctions. 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.

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 pediátrica 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 alteraciones 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 ejecutivas 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.

Self-reported attention and hyperactivity symptoms among adults with epilepsy.

BACKGROUND: Patients with epilepsy (PWE) frequently have comorbid psychiatric disorders, the most common of which are depression and anxiety. Attention deficit disorder with hyperactivity (ADHD) is also more frequent among PWE, though that condition has been scarcely studied among the adult PWE population. OBJECTIVE: This study aimed to compare the presence of ADHD symptoms between adult PWE and the general population. METHODS: This was an observational case-control study. Ninety-five adult PWE from a tertiary center in southern Brazil were compared with 100 healthy controls. All subjects were submitted to three structured scales: 1) the World Health Organization Adult ADHD Self-Report Scale version 1.1 (ASRS); 2) the Hospital Anxiety and Depression Scale (HADS); and 3) the Adverse Events Profile (AEP). Dichotomic variables were analyzed through chi-square test and Fisher's exact test, as appropriate, and non-parametric variables were analyzed through the Mann-Whitney U test. RESULTS: Medians and interquartile ranges (IR) were: 1) ASRS: 26.00 (IR: 18 to 38) among PWE versus 17.00 (IR: 11 to 24) among controls, p < 0.001; 2) HADS: 14.00 (IR: 8 to 21) among PWE versus 11.00 (IR: 8 to 16) among controls, p = 0.007; 3) AEP: 3800 (IR: 31 to 49) among PWE versus 33.00 (IR: 23 to 43) among controls, p = 0.001. CONCLUSION: PWE showed a higher burden of symptoms of ADHD, depression, and anxiety when compared with controls, which replicates in the Brazilian population the findings of current literature that point toward a higher prevalence of such disorders among PWE.

ANTECEDENTES: Pacientes com epilepsia (PCE) frequentemente apresentam comorbidades psiquiátricas, principalmente depressão e ansiedade. O transtorno do déficit de atenção e hiperatividade (TDAH) também é mais frequente nos PCE, porém foi pouco estudado na população adulta de PCE. OBJETIVO: Comparar a presença de sintomas de TDAH entre PCE adultos e a população geral. MéTODOS: Noventa e cinco PCE adultos de um centro terciário no Sul do Brasil foram comparados a 100 controles saudáveis. Todos os sujeitos foram submetidos a três escalas estruturadas: 1) a Escala Autorrelatada de TDAH em Adultos da Organização Mundial da Saúde, versão 1.1 (ASRS); 2) a Escala Hospitalar de Ansiedade e Depressão (HADS); e 3) o Perfil de Eventos Adversos (AEP). Variáveis dicotômicas foram analisadas através dos testes chi-quadrado e exato de Fisher, conforme apropriado, e as variáveis não paramétricas foram analisadas através do teste U de Mann-Whitney. RESULTADOS: As medianas e os intervalos interquartis (IIQ) foram: 1) ASRS: 26.00 (IIQ: 18 a 38) em PCE versus 17.00 (IIQ: 11 a 24) nos controles, p < 0,001; 2) HADS: 14.00 (IIQ: 8 a 21) em PCE versus 11.00 (IIQ: 8 a 16) nos controles, p = 0,007; 3) AEP: 38.00 (IIQ: 31 a 49) em PCE versus 33.00 (IIQ: 23 a 43) nos controles, p = 0,001. CONCLUSãO: PCE apresentaram uma maior carga de sintomas de TDAH, depressão e ansiedade quando comparados aos controles, o que replica na população brasileira os achados da literatura atual, que apontam para uma maior prevalência de tais transtornos entre PCE.

Association Between Attention-Deficit/Hyperactivity Disorder Symptoms and Sleep, Bruxism and Dental Trauma in Pediatric Population: A Preliminary Study.

Purpose: To evaluate the association between attention-deficit/hyperactivity disorder (ADHD) symptoms reported by parents and the variables sleep problems, possible sleep bruxism, possible awake bruxism and dental trauma (DT), and its mode of occurrence in children and adolescents.
Methods: A cross-sectional study was conducted with the parents of 144 four- to 16-year-old subjects through a questionnaire on demographics, subjects' sleep, self-reported bruxism and DT mode of occurrence. The Swanson, Nolan and Pelham scale IV was used to assess ADHD signs and subtypes. Bivariate and multivariate analysis were performed (P <0.05).
Results: The subjects' mean age was 7.9 years (±2.8 years) and 50.7 percent were boys. DT was reported in 80 percent of those with the hyperactive/impulsive subtype (ADHD-HI) and 72.7 percent of those with the combined subtype (ADHD-C). DT was caused solely by falls in the ADHD-C and inattention subtypes (ADHD-I). ADHD-C was associated with somniloquy (prevalence ratio [PR]=1.075; P =0.010). ADHD-HI was associated with bad sleep quality (PR=1.194; P =0.005), possible sleep bruxism (PR=1.088, 95% confidence interval=1.006 to 1.176; P =0.034), possible awake bruxism (PR=1.146; P =0.024) and sleep duration (PR=0.88; P =0.02).
Conclusion: ADHD-C and -HI subtypes were associated with sleep characteristics. Possible sleep and awake bruxism were associated with symptoms of ADHD-HI. Despite no significant association, DT was present in most ADHD subjects, mostly due to falls.

[The impact of ADHD on reading]. / El impacto del TDAH sobre la lectura.

Beyond the frequent coexistence of attention deficit hyperactivity disorder (ADHD) and reading disorder (dyslexia), the present review aims to examine the available empirical evidence on how ADHD negatively impacts on learning to read. Existing data suggest that the presence of the disorder (especially inattention symptoms), may affect i) the correct acquisition of reading, either directly or through its influence on the precursors to reading; ii) decoding skills themselves (reading accuracy and fluency), both directly and indirectly through its influence on cognitive processes such as distractibility or executive functions; and iii) reading comprehension, probably indirectly through the executive and verbal memory difficulties characteristic of ADHD. These findings have important implications for better characterizing and intervening on reading difficulties in ADHD, whether clinical or subclinical.

Más allá de la frecuente coexistencia del trastorno por déficit de atención con hiperactividad (TDAH) y el trastorno específico del aprendizaje de la lectura, la presente revisión pretende examinar la evidencia empírica disponible sobre cómo el TDAH impacta negativamente sobre el aprendizaje de la lectura. Los datos existentes apuntan a que la presencia del trastorno (especialmente los síntomas de falta de atención), puede afectar a i) la correcta adquisición de lectura, ya sea de manera directa o a través de su influencia sobre los precursores de la lectura; ii) las propias habilidades de decodificación (precisión y fluidez lectora), tanto de manera directa como indirecta a través de su influencia sobre procesos cognitivos como la distracción o las funciones ejecutivas; y ii) la comprensión lectora, probablemente de manera indirecta por las dificultades ejecutivas y en la memoria de trabajo verbal características del TDAH. Estas conclusiones presentan importantes implicaciones para caracterizar e intervenir mejor sobre las dificultades lectoras en el TDAH, ya sean clínicas o subclínicas.

[Autism spectrum disorder and attention-deficit/hyperactivity disorder: challenge in diagnosis and treatment]. / Trastornos del espectro autista y trastornos por déficit de atención con hiperactividad: desafíos en el diagnóstico y tratamiento.

The coexistence of autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) definitely poses new challenges, such as making an early diagnosis, considering that the former is usually diagnosed 2 years later in children with ADHD comorbid with autism compared to those with ASD alone; this is a problem at a personal, family and social level, since they must receive timely intervention. This coexistence raises questions about the efficacy of treatment in ADHD in people with autism, genetic, anatomical and functional concordances, among others; these are the challenges that are currently posed. In this review, we present some responses to the challenges posed by such coexistence, and we highlight some pending issues to be solved, being these of great importance for their better understanding and management. In all patients with ADHD or ASD, a coexistence between them should be sought. There are shared functional brain alterations in both disorders identified by functional brain magnetic resonance imaging; the treatment established for ADHD is also effective in this comorbidity.

La coexistencia del trastorno del espectro autista (TEA) y trastorno por déficit de atención con hiperactividad (TDAH) definitivamente plantea nuevos desafíos, como la realización de un diagnóstico temprano teniendo en cuenta que el primero generalmente es diagnosticado 2 años después en los niños con TDAH comórbidos; esto es un problema a nivel personal, familiar y social, ya que deben recibir intervención oportuna. Esta coexistencia genera interrogantes sobre la eficacia del tratamiento en TDAH en personas con autismo, concordancias genéticas, anatómicas y funcionales entre otros; y son los retos que se plantean en la actualidad. En la presente revisión exponemos algunas respuestas a los desafíos dados por tal coexistencia y resaltamos algunos temas pendientes a resolver, siendo estos de gran importancia para su mejor entendimiento y manejo. En todos los pacientes con TDAH o TEA se debe buscar una coexistencia entre ellos. Existen alteraciones funcionales cerebrales compartidas en ambos trastornos identificadas por resonancia magnética funcional cerebral; el tratamiento establecido para el TDAH es también eficaz en esta comorbilidad.

Periodontal outcomes of children and adolescents with attention deficit hyperactivity disorder: a systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis aimed to answer the following question: Are children and adolescents with attention deficit hyperactivity disorder (ADHD) more likely to have gingival or periodontal disease-related outcomes than their non-ADHD peers? METHODS: Searches were conducted in the following databases: Embase, Scopus, Web of Science, and PubMed. Google Scholar and OpenGrey were also verified. Observational studies were included in which children and adolescents with ADHD were compared with their healthy peers in terms of gingival and/or periodontal endpoints. Bias appraisal was performed using the Joann Briggs tool for case-control and cross-sectional studies. Meta-analysis was performed using R language. Results are reported as mean difference (MD) and odds ratio (OR). Statistical analyses were performed in RStudio. RESULTS: A total of 149 records were identified in the searches. Seven studies were included. The meta-analysis showed that children and adolescents with ADHD had a higher mean gingival bleeding index (percentage) than their non-ADHD peers (MD = 11.25; CI = 0.08-22.41; I2 = 73%). There was no difference between groups for plaque index (MD = 4.87; CI = - 2.56 to 12.30; I2 = 63%) and gingivitis (OR = 1.42; CI = 0.22-9.21; I2 = 76%). Regarding the assessment of risk of bias, the major issue found in the articles was the absence of analyses for the control of confounding factors. CONCLUSION: Children and adolescents with ADHD had more gingival bleeding than their non-ADHD peers, but no difference regarding plaque or gingivitis was detected between groups.

Global DNA methylation changes in adults with attention deficit-hyperactivity disorder and its comorbidity with bipolar disorder: links with polygenic scores.

Genetic and environmental factors contribute to the etiology of Attention Deficit-Hyperactivity Disorder (ADHD). In this sense, the study of epigenetic mechanisms could contribute to the understanding of the disorder's neurobiology. Global DNA methylation (GMe) evaluated through 5-methylcytosine levels could be a promising epigenetic biomarker to capture long-lasting biological effects in response to environmental and hormonal changes. We conducted the first assessment of GMe levels in subjects with ADHD (n = 394) and its main comorbidities in comparison to populational controls (n = 390). Furthermore, given the high genetic contribution to ADHD (heritability of 80%), polygenic risk scores (PRS) were calculated to verify the genetic contribution to GMe levels in ADHD and the comorbidities associated with GMe levels. The GMe levels observed in patients were lower than controls (P = 1.1e-8), with women being significantly less globally methylated than men (P = 0.002). Regarding comorbidities, the presence of bipolar disorder (BD) among patients with ADHD was associated with higher methylation levels compared to patients with ADHD without BD (P = 0.031). The results did not change when pharmacological treatment was accounted for in the analyses. The ADHD and BD most predictive PRSs were negatively (P = 0.0064) and positively (P = 0.0042) correlated with GMe, respectively. This study is the first to report an association between GMe, ADHD, and its comorbidity with BD and associations between PRSs for specific psychiatric disorders and GMe. Our findings add to previous evidence that GMe may be a relevant piece in the psychiatric disorders' etiological landscape.

[Care for patients with traumatic brain injury]. / La atención en pacientes con lesión traumática cerebral.

Traumatic brain injury (TBI) as well as Attention Deficit Disorder with or without hyperactivity (ADHD) are very common problems that affect children. It is known that patients who suffer a traumatic brain injury may present symptoms of ADHD, which often go unnoticed in the acute period, especially when there are more serious injuries that hide them and are only evident when the patient returns to their regular cognitive activity after discharge. Symptoms can vary depending on the mechanism of injury, the location in the brain where the trauma or its effects occur, complications, and the severity of the injury. Some symptoms of TBI are identical to those of ADHD, making the diagnosis of these patients more difficult to discern either because the patient or their parents report them together or when the patient already had pre-existing ADHD. We describe some clinical scenarios in this article in which there is an interaction between these two processes that are explained in part because both can affect similar nerve conduction pathways and neurotransmitters. The clinician must recognize attention problems in patients with TBI and other presentations and offer appropriate and timely treatment when symptoms interfere with the patient's functioning. Treatment of ADHD in patients with TBI uses accommodations and medications similar to those used in patients who only have ADHD, but depending on the severity, they can vary in duration.

La lesión traumática cerebral (LTC) al igual que el trastorno por déficit de atención con o sin hiperactividad (TDAH) son problemas muy frecuentes que afectan a los niños. Es conocido que los pacientes que sufren una lesión traumática cerebral pueden presentar síntomas del TDAH, los cuales a menudo pasan desapercibidos en el período agudo, especialmente cuando hay lesiones más graves que los ocultan y solo se evidencian cuando el paciente regresa a su actividad cognitiva regular después del alta. Los síntomas pueden variar dependiendo del mecanismo de lesión, el lugar del cerebro en donde ocurre el trauma o sus efectos, complicaciones y la severidad de la lesión. Algunos síntomas de LTC son idénticos a los del TDAH, haciendo que el diagnóstico de estos pacientes sea más difícil de discernir, ya sea porque el paciente o sus padres los reportan juntos cuando el paciente ya tenía un TDAH preexistente. Existen algunos escenarios clínicos que describimos en este artículo en los cuales hay una interacción entre estos dos, que se explican en parte porque ambos pueden afectar vías de conducción nerviosa y neurotransmisores similares. El clínico debe reconocer los problemas de atención en los pacientes con LTC y otras presentaciones y ofrecer tratamiento adecuado y oportuno cuando los síntomas interfieren con el funcionamiento del paciente. El tratamiento del TDAH en pacientes con LTC usa acomodaciones y medicamentos similares a los que se usan en pacientes que solo tienen TDAH, pero dependiendo de la severidad pueden variar en su duración.

Association between Polygenic Risk Scores for ADHD and Asthma: A Birth Cohort Investigation.

OBJECTIVE: Shared genetic mechanisms have been hypothesized to explain the comorbidity between ADHD and asthma. To evaluate their genetic overlap, we relied on data from the 1982 Pelotas birth cohort to test the association between polygenic risk scores (PRSs) for ADHD (ADHD-PRSs) and asthma, and PRSs for asthma (asthma-PRSs) and ADHD. METHOD: We analyzed data collected at birth, 2, 22, and 30 years from 3,574 individuals. RESULTS: Subjects with ADHD had increased risk of having asthma (OR 1.92, 95% CI 1.01-3.66). The association was stronger for females. Our results showed no evidence of association between ADHD-PRSs and asthma or asthma-PRSs and ADHD. However, an exploratory analysis suggested that adult ADHD might be genetically associated with asthma. CONCLUSION: Our results do not support a shared genetic background between both conditions. Findings should be viewed in light of important limitations, particularly the sample size and the self-reported asthma diagnosis. Studies in larger datasets are required to better explore the genetic overlap between adult ADHD and asthma.

Caffeine-related genes influence anxiety disorders in children and adults with ADHD.

Attention-deficit/hyperactivity disorder (ADHD) and anxiety disorders (AD) frequently co-occur, increasing morbidity and challenging treatment. Caffeine is a central nervous system stimulant and acts in the brain through adenosine receptors, influencing attention, alertness, and anxiety. In the present study, we performed a gene-set analysis to verify if genes related to caffeine response are associated with anxiety disorders in 240 children and 406 adults with ADHD. We demonstrated an association between the gene-set with AD in children (P = 0.0054) and with the number of anxiety disorders in adults (P = 0.0197). In order to test if this effect is a result of anxiety in general or is related to AD comorbid with ADHD, we evaluated the association between caffeine gene-set with AD in an adult control sample. The gene-set was neither associated with the AD presence (P = 0.3008) nor with the number of AD (P = 0.5594) in this control sample. We also test this gene set with ADHD (n = 55,374) and AD (n = 18,186) GWAS summary statistics, and we did not observe significant results with ADHD (P = 0.5587) or AD (P = 0.3930). These findings suggest the caffeine-related genes play a role in the etiology of an anxiety disorder phenotype present in children and adults with ADHD.

Dental Caries in Children with Attention Deficit/Hyperactivity Disorder: A Meta-Analysis.

OBJECTIVES: The aim of the study was to evaluate whether children with attention deficit/hyperactivity disorder (ADHD) are more affected by dental caries than children without ADHD by means of a systematic review and meta-analysis. DESIGN: Electronic searches were performed in 4 databases (PubMed, Embase, Scopus, and Web of Science) in July 2021. Grey literature search in OpenGrey, a search in Google Scholar, and searches in the reference list of included articles were also conducted. The eligibility criteria were observational studies in which children with ADHD were compared with children without ADHD with respect to the dental caries. Study selection, data extraction, and risk of bias assessment, applying the Joanna Briggs tool were performed by 2 reviewers independently. Meta-analysis and assessment of heterogeneity among studies were conducted with the meta-package of RStudio using the R programming language (R Core Team, Vienna, Austria). Results of meta-analysis were provided in mean difference (MD), odds ratio (OR), and confidence intervals (CIs). For assessment of heterogeneity, Baujat plot and influence analysis plot were obtained. RESULTS: Thirteen studies were included and 10 were incorporated into meta-analyses. The meta-analysis showed that children with ADHD had a higher decayed, missing, and filled teeth (DMFT) index than their peers without ADHD (I2 = 42%; MD = 0.75 [0.38-1.13]). For decayed, missing, and filled surfaces (I2 = 0; MD = 0.39 [-0.02 to 0.80]) and decayed surfaces (ds) (I2 = 0%; MD = 0.35 [-0.63 to 1.33]), no difference between groups was observed. In addition, children with ADHD had higher odds of having dental caries than their healthy peers (OR = 3.31 [1.25, 8.73]; I2 = 0%). After assessment of heterogeneity among studies, sensitivity analysis was conducted for DMFT. One study was removed and the significant difference between groups remained. Children with ADHD had a significantly higher DMFT index than their peers without ADHD (MD = 0.98 [CI = 0.75, 1.20]; I2 = 0%) Risk of bias ranged from low to high. CONCLUSION: The main shortcoming of the included studies is the high risk of bias regarding the strategies to deal with confounding factors. Within its limitations, this systematic review and meta-analysis demonstrated that children with ADHD were more likely to develop dental caries than their healthy counterparts. FUNDING: No funding.

Two sides of the same coin: ADHD affects reactive but not proactive inhibition in children.

Children with attention-deficit/hyperactivity disorder (ADHD) present a deficit in inhibitory control. Still, it remains unclear whether it comes from a deficit in reactive inhibition (ability to stop the action in progress), proactive inhibition (ability to exert preparatory control), or both.We compared the performance of 39 children with ADHD and 42 typically developing children performing a Simon choice reaction time task. The Simon task is a conflict task that is well-adapted to dissociate proactive and reactive inhibition. Beyond classical global measures (mean reaction time, accuracy rate, and interference effect), we used more sophisticated dynamic analyses of the interference effect and accuracy rate to investigate reactive inhibition. We studied proactive inhibition through the congruency sequence effect (CSE).Our results showed that children with ADHD had impaired reactive but not proactive inhibition. Moreover, the deficit found in reactive inhibition seems to be due to both a stronger impulse capture and more difficulties in inhibiting impulsive responses. These findings contribute to a better understanding of how ADHD affects inhibitory control in children.

Brief Report: Associations Between Cognitive Control Processes and Traits of Autism Spectrum Disorder (ASD), attention-Deficit/Hyperactivity Disorder (ADHD) and Anxiety in Children at Elevated and Typical Familial Likelihood for ASD.

Shared difficulties with cognitive control may play a role in co-occurring mental health problems frequently observed in autistic children. We investigated how different cognitive control processes (inhibitory control, conflict resolution, cognitive flexibility) associated with traits of autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD) and anxiety in 7-year-old children at elevated (n = 44) and typical (n = 37) familial likelihood for ASD. Poor inhibitory control was associated with higher ADHD traits. Better inhibitory control and poorer cognitive flexibility predicted higher anxiety traits. Cognitive control processes were not associated dimensionally with autistic traits, though better conflict resolution predicted greater likelihood of meeting diagnostic criteria for ASD in categorical analysis. These findings suggest that different cognitive control alterations are associated with ASD, ADHD and anxiety.

Internet Addiction and Attention in Adolescents: A Systematic Review.

Internet addiction (IA) has been explored worldwide and involves some features that might harm social, psychological, and functional aspects. The vulnerability of adolescents might result in some addictive behaviors, and the Internet is one of them. The aim of this systematic review was to identify empirical studies that have been done to explore instruments that have been used to assess IA and to verify what variables and comorbidities are related to IA in adolescents, including executive functions, such as attention. To accomplish our aim, a systematic search was conducted in the following databases: PubMed, Web of Science, and PsycINFO. Some inclusion and exclusion criteria were used to select the studies and 44 in total were analyzed independently. The results showed that the most used instrument to assess IA is the Young's Internet Addiction Test. A few studies have been developed in the Western world, and most of them have analyzed attention bias in attention-deficit/hyperactivity disorder (ADHD) and non-ADHD groups. Furthermore, other variables have been widely explored in the studies, such as depression, sleeping patterns, body weight, aggressiveness, and other addictive substances.

Relationship between symptoms of attention-deficit/hyperactivity disorder and speech-language-hearing aspects / Relação entre sintomas do transtorno de déficit de atenção/hiperatividade e aspectos fonoaudiológicos

ABSTRACT Purpose: to investigate the association of symptoms of inattention and hyperactivity with language development and cognitive, environmental, socioeconomic, and quality of life aspects in children with attention-deficit/hyperactivity disorder. Methods: an observational, analytical, cross-sectional study with a sex-stratified sample of 38 children 7 to 12 years old, diagnosed with attention-deficit/hyperactivity disorder. The assessments approached sociodemographic and environmental aspects, the quality of life, language comprehension, rapid automatic naming, phonological working memory, vocabulary, reading and writing processes and metalinguistic skills. Descriptive and bivariate analyses were conducted at the 5% significance level. Results: there was a statistically significant association between the profile of attention-deficit/hyperactivity disorder and behavioral aspects. There was no significant association of the forms of manifestation of attention-deficit/hyperactivity disorder with the quality of life, oral language, written language and phonological processing skills. Conclusion: children with hyperactive profiles had a better performance, whereas children with combined and predominantly inattentive profiles had similar performances. Although no statistically significant associations were found between attention-deficit/hyperactivity disorder and most of the variables analyzed in this research, it contributes to the discussion of the speech-language-hearing diagnosis.

RESUMO Objetivo: investigar a associação de sintomas de desatenção e hiperatividade com o desenvolvimento de linguagem, aspectos cognitivos, ambientais, socioeconômicos e de qualidade de vida, em crianças com Transtorno do Déficit de Atenção e Hiperatividade. Métodos: estudo observacional, analítico, transversal, com amostra estratificada por sexo e composta por 38 crianças de sete a doze anos de idade, com diagnóstico de Transtorno do Déficit de Atenção e Hiperatividade.

Foram realizadas análises descritiva e bivariada, adotando nível de significância de 5%. Resultados: houve associação com significância estatística entre perfil do Transtorno do Déficit de Atenção e Hiperatividade e aspectos comportamentais. Não houve associação significante das formas de apresentação do Transtorno do Déficit de Atenção e Hiperatividade com qualidade de vida, linguagem oral, linguagem escrita e habilidades de processamento fonológico. Conclusão: verificou-se melhor desempenho das crianças com perfil hiperativo e desempenho semelhante entre os perfis combinado e predominantemente desatento. Embora não tenham sido encontradas associações estatisticamente significantes entre Transtorno do Déficit de Atenção e Hiperatividade e a maioria das variáveis analisadas nesta pesquisa, ela contribui para a discussão do diagnóstico fonoaudiológico.

Attention Deficit Hyperactivity Disorder Increases Nicotine Addiction Severity in Adults Seeking Treatment for Substance Use Disorders: The Role of Personality Disorders.

AIMS: To examine the role of attention deficit/hyperactivity disorder (ADHD) and impulsive personality disorders in nicotine addiction severity among treatment-seeking substance use disorder (SUD) patients. METHODS: In a cross-sectional study, we examined data from the second International ADHD in Substance Use Disorders Prevalence Study (IASP-2) on 402 adults in SUD treatment from Puerto Rico, Hungary, and Australia using diagnostic interviews for ADHD, antisocial (ASP) and borderline (BPD) personality disorders, and the self-report Fagerström Test of Nicotine Dependence (FTND). We compared SUD patients with and without ADHD on nicotine addiction severity. We tested direct and indirect pathways from ADHD to nicotine addiction and mediation through ASP and BPD. RESULTS: Overall, 81.4% of SUD patients reported current cigarette smoking. SUD patients with ADHD had higher FTND scores and smoked more cigarettes than those without ADHD, with an earlier onset and more years of smoking. ASP mediated the effect of ADHD on all aspects of nicotine addiction severity, whereas BPD did so only on some aspects of nicotine addiction severity. CONCLUSIONS: SUD patients with comorbid ADHD show more severe nicotine addiction than those without, which is largely explained by comorbid impulsive personality disorders. In SUD patients, it is important to screen for adult ADHD and other psychiatric disorders, especially those with impulse control deficits such as ASP and BPD.

Relación entre índice de masa corporal y trastorno por déficit de atención con hiperactividad en niños / Relationship between body mass index and attention deficit disorder with hyperactivity in children

Introducción: El índice de masa corporal es un indicador de la densidad corporal. El trastorno por déficit de atención con hiperactividad es un síndrome que presenta tres síntomas: inatención, hiperactividad e impulsividad. Objetivo: Analizar la relación entre el índice de masa corporal y el trastorno por déficit de atención con hiperactividad en niños. Métodos: Investigación observacional, transversal, analítica bivariada y ambispectiva, desarrollada en 111 niñas y 125 niños, de 10 a 12 años de edad estudiantes de la Unidad Educativa Hispano América de la ciudad de Ambato, Ecuador, en el período septiembre 2017- febrero 2018. Los datos del índice de masa corporal y el trastorno por déficit de atención se procesaron en Microsoft Excel, el software Minitab® 18.1 para el cálculo de los coeficientes de correlación de Pearson y Spearman, y prueba de Grubbs para comprobar normalidad y análisis de valores atípicos. Resultados: La media del índice de masa corporal fue de 20,15 en niños y 20,63 en niñas, lo que se consideró normal. El trastorno por déficit de atención: 93,7 por ciento de niñas y 90,4 por ciento de niños, también fue normal. En estos últimos, existió una ligera predisposición por este trastorno. La correlación entre ambas variables fue ligeramente positiva: niñas 0,02 y niños 0,457. Conclusiones: El índice de masa corporal y el trastorno por déficit de atención con hiperactividad tienen parámetros normales en niñas y niños y existe entre ambos una correlación positiva débil. Es necesario establecer estrategias educativas para la disminución de la obesidad y malnutrición infantil(AU)

Introduction: The body mass index is an indicator of body density, determined by the relationship between body weight and height. Attention deficit hyperactivity disorder is a syndrome with three symptoms: inattention, hyperactivity and impulsivity. Objective: To analyze the relationship between the body mass index and the attention deficit hyperactivity disorder in students. Methods: Observational, cross-sectional, bivariate and ambispective analytical research, carried out in a population of 111 girls and 125 boys, from 10 to 12 years of the Hispanic American Education Unit of the city of Ambato, Ecuador, in the period September 2017 - February 2018. Processing data in Microsoft Excel for body mass index and for the attention deficit hyperactivity disorder, and with Minitab® 18.1 software for the calculation of coefficients of Pearson and Spearman correlation, as well as the normality tests and analysis of outliers with the Grubbs test. Results: The average for body mass index was 20.15 in boys and 20.63 in girls, considered normal. Normal results were obtained in the attention deficit hyperactivity disorder in 93.7 percent of girls and 90.4 percent of boys, there being a slight predisposition for this disorder. The correlation between both variables was slightly positive: girls 0.202 and boys 0.457. Conclusions: Both, body mass index and the attention deficit hyperactivity disorder have normal parameters in girls and boys, with a weak positive correlation between them. It was proposed to establish educational strategies for the reduction of obesity and child malnutrition(AU)

[Attention-deficit/hyperactivity disorder and substance abuse. Scientific evidence]. / Trastorno por déficit de atención/hiperactividad y uso de sustancias. Evidencias científicas.

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental alteration of biological basis that started in childhood may persist during adolescence-youth and, despite what was believed until not many years ago, also in adulthood up to 50-60% of those affected, producing a significant clinical and psychosocial deterioration. In spite of being a syndrome easily identifiable by the triad: inattention, hyperactivity and impulsivity that characterizes it, in clinical practice there are different circumstances that hinder and complicate its diagnosis and treatment. One of the most significant is the presence, both in childhood and adulthood, of other comorbid mental disorders. It is from adolescence-youth when together with ADHD we can detect the presence of personality, mood and anxiety disorders and especially the use of several substances. The evidences existing until now show how the comorbidity of ADHD and substance use disorder influence the evolutionary course of both, complicating the approach, the treatment and, therefore, aggravating the final prognosis. The difficulties in their approach and the scarcity of treatment options make us underline the importance of preventive treatment in the infantile stage, starting from psychoeducation programs focused on the vulnerability of these patients to substances and the consequences associated with consumption.

El trastorno por déficit de atención con hiperactividad (TDAH) es una alteración del neurodesarrollo de base biológica que iniciado en la infancia puede persistir durante la adolescencia-juventud y, a pesar de lo que se pensaba hasta hace no muchos años, también en la edad adulta hasta en un 50-60% de los afectados, produciendo un notable deterioro clínico y psicosocial. A pesar de tratarse de un síndrome fácilmente identificable por la triada: desatención, hiperactividad e impulsividad que le caracteriza, en la práctica clínica existen diferentes circunstancias que dificultan y complican su diagnóstico y tratamiento. Una de las más significativas es la presencia, tanto en la infancia como en la edad adulta, de otros trastornos mentales comórbidos. Es a partir de la adolescencia-juventud cuando junto al TDAH podemos detectar la presencia de trastornos de la personalidad, trastornos del estado de ánimo, trastornos de ansiedad y muy especialmente trastornos por uso de sustancias. Las evidencias existentes hasta el presente muestran como la comorbilidad del TDAH y el trastorno por uso de sustancias influyen en el curso evolutivo de ambos, complicando el abordaje, el tratamiento y consecuentemente agravando el pronóstico final. Las dificultades en su abordaje y la escasez de opciones de tratamiento nos hacen subrayar la importancia del tratamiento preventivo en la etapa infantil a partir de programas de psicoeducación centrados en la vulnerabilidad de estos pacientes a las sustancias y las consecuencias asociadas al consumo.

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental alteration of biological basis that started in childhood may persist during adolescence-youth and, despite what was believed until not many years ago, also in adulthood up to 50-60% of those affected, producing a significant clinical and psychosocial deterioration. In spite of being a syndrome easily identifiable by the triad: inattention, hyperactivity and impulsivity that characterizes it, in clinical practice there are different circumstances that hinder and complicate its diagnosis and treatment.
