Differential impact of a multimodal versus pharmacological therapy on the core symptoms of Attention Deficit Hyperactivity Disorder in childhood
2015
Abstract The aim of this study was to analyze the relative and differential efficacy of a combined versus medical treatment to reduce the symptoms of ADHD children in the school and family environment. A total of 100 subjects participated: 20 children with ADHD, their 40 parents and their 40 teachers. Half of the subjects were assigned to the drug group and half to the combined (drug plus psychosocial, psychoeducational intervention with teachers and mothers/fathers). Results The group analyses indicated that both treatments were effective, without significant differences between them. Individualized clinical analyses indicated that higher percentages of improvement and normalization were o…
Vitamin D in Pregnancy and Attention Deficit Hyperactivity Disorder-like Symptoms in Childhood
2015
Vitamin D status during prenatal brain development may influence risk of attention deficit and hyperactivity disorder (ADHD) symptoms in childhood. However, there are no prospective studies addressing this hypothesis. We aimed to examine whether maternal vitamin D status in pregnancy is associated with risk of ADHD-like symptoms in offspring.We conducted a prospective study analyzing data from 1,650 mother-child pairs from five birth cohorts embedded in the INMA Project (Spain, 1997-2008). Maternal vitamin D status in pregnancy was estimated by measuring plasma concentration of 25-hydroxyvitamin D3 [25(OH)D3] at 13 weeks of gestation. Children were assessed by teachers for ADHD-like symptom…
Correction: Santa-Marina et al. Maternal Ferritin Levels during Pregnancy and ADHD Symptoms in 4-Year-Old Children: Results from the INMA-INfancia y …
2021
Ferritin status during prenatal brain development may influence the risk of attention deficit and hyperactivity disorder (ADHD) symptoms in childhood. We investigated the association of maternal ferritin in pregnancy and ADHD-like symptoms in offspring. A total of 1095 mother-child pairs from three birth cohorts of the INMA Project (Spain) were studied. Maternal plasma ferritin in pregnancy was measured at 11.57 weeks of gestation. Children's ADHD-like symptoms at ages 4-5 years were assessed using the ADHD Rating Scale-IV. The count model of the zero-inflated Poisson regression model showed a significant inverse association between ferritin (continuous variable) and inattention, β = -0.19 …
Maternal Iodine Status During Pregnancy Is Not Consistently Associated with Attention-Deficit Hyperactivity Disorder or Autistic Traits in Children
2020
Background: Severe iodine deficiency during pregnancy can cause intellectual disability, presumably through inadequate placental transfer of maternal thyroid hormone to the fetus. The association between mild-to-moderate iodine deficiency and child neurodevelopmental problems is not well understood. Objectives: We investigated the association of maternal iodine status during pregnancy with child attention-deficit hyperactivity disorder (ADHD) and autistic traits. Methods: This was a collaborative study of 3 population-based birth cohorts: Generation R (n = 1634), INfancia y Medio Ambiente (n = 1293), and the Avon Longitudinal Study of Parents and Children (n = 2619). Exclusion criteria were…
Distinguishing the efficacy and sedative effects of guanfacine extended release in children and adolescents with attention-deficit/hyperactivity diso…
2019
The present study investigated whether symptom reduction in children and adolescents with attention-deficit/hyperactivity disorder (ADHD) treated with guanfacine extended release (GXR) can be explained by sedative effects of the medication. Data from four double-blind, randomized, placebo-controlled, phase 3 trials of GXR monotherapy (1-7 mg/day; morning administration) in children (aged 6-12 years) and adolescents (aged 13-17 years) with ADHD were analyzed post hoc. Two studies used forced-dose titration and two used flexible-dose titration. Efficacy was determined using ADHD Rating Scale IV (ADHD-RS-IV) scores. Sedative treatment-emergent adverse events (TEAEs) included somnolence, sedati…
Understanding Discipline in Families of Children with Attention-Deficit/Hyperactivity Disorder: A Structural Equation Model
2009
One hundred and fifty-five mothers of children with attention deficit/hyperactivity disorder (ADHD) completed a semi-structured interview, the Parenting Stress Index Questionnaire (Abidin, 1990), to evaluate parenting stress. The Parenting Scale (Arnold, O’Leary, Wolff & Acker, 1993) was also administered to measure dysfunctional discipline strategies. Structural equation modeling was used to test a model in which the independent variables were the Child’s Characteristics and the Socio-Educational Status of his or her family; intermediate variables were Parenting Stress concerning the Child Domain and concerning the Parent Domain; and the dependent variable was Parental Discipline. The resu…
Analysis of Personal and Family Factors in the Persistence of Attention Deficit Hyperactivity Disorder: Results of a Prospective Follow-Up Study in C…
2015
Objectives To study the course of ADHD during childhood and analyze possible personal and family predictor variables of the results. Method Sixty-one children with ADHD who were between 6 and 12 years old at the baseline assessment were evaluated 30 months later (mean age at baseline: 8.70 ± 1.97; mean age at follow-up: 10.98 ± 2.19). Status of ADHD in follow-up was identified as persistent (met DSM-IV-TR criteria according to parents’ and teachers’ ratings), contextually persistent (met ADHD criteria according to one informant, and there was functional impairment) and remitted ADHD (with subthreshold clinical symptomatology). Associated psychological disorders of the three groups were anal…
ADHD symptoms and learning behaviors in children with ASD without intellectual disability. A mediation analysis of executive functions
2018
In spite of its importance for education, the relationship between learning behaviors (LB), attention deficit hyperactivity disorder symptoms (ADHD) and executive functioning (EF) in children with autism spectrum disorder (ASD) has hardly been explored. The first objective of the present study was to compare children with ASD without intellectual disability and children with typical development (TD) on ADHD symptoms and learning behaviors: Motivation/ competence, attitude toward learning, persistence on the task, and strategy/flexibility. The second objective was to analyze the mediator role of behavioral regulation and metacognition components of EF between ADHD symptoms and learning behav…
Differential dopamine receptor D4 allele association with ADHD dependent of proband season of birth
2008
Contains fulltext : 70196.pdf (Publisher’s version ) (Closed access) Season of birth (SOB) has been associated with attention deficit hyperactivity disorder (ADHD) in two existing studies. One further study reported an interaction between SOB and genotypes of the dopamine D4 receptor (DRD4) gene. It is important that these findings are further investigated to confirm or refute the findings. In this study, we investigated the SOB association with ADHD in four independent samples collected for molecular genetic studies of ADHD and found a small but significant increase in summer births compared to a large population control dataset. We also observed a significant association with the 7-repeat…
Genome-wide association study of motor coordination problems in ADHD identifies genes for brain and muscle function.
2012
Item does not contain fulltext OBJECTIVES: Motor coordination problems are frequent in children with attention deficit/hyperactivity disorder (ADHD). We performed a genome-wide association study to identify genes contributing to motor coordination problems, hypothesizing that the presence of such problems in children with ADHD may identify a sample of reduced genetic heterogeneity. METHODS: Children with ADHD from the International Multicentre ADHD Genetic (IMAGE) study were evaluated with the Parental Account of Children's Symptoms. Genetic association testing was performed in PLINK on 890 probands with genome-wide genotyping data. Bioinformatics enrichment-analysis was performed on highly…
