Shared genetic influences between dimensional ASD and ADHD symptoms during child and adolescent development / E. STERGIAKOULI in Molecular Autism, 8 (2017)

Titre : Shared genetic influences between dimensional ASD and ADHD symptoms during child and adolescent development Type de document : Texte imprimé et/ou numérique Auteurs : E. STERGIAKOULI, Auteur ; George DAVEY SMITH, Auteur ; J. MARTIN, Auteur ; D. H. SKUSE, Auteur ; W. VIECHTBAUER, Auteur ; S. M. RING, Auteur ; A. RONALD, Auteur ; D. E. EVANS, Auteur ; S. E.

Langues : Anglais (eng) Mots-clés : ADHD symptoms Alspac Clinical ADHD Genetic overlap Social communication Index. décimale : PER Périodiques Résumé : BACKGROUND: Shared genetic influences between attention-deficit/hyperactivity disorder (ADHD) symptoms and autism spectrum disorder (ASD) symptoms have been reported. Cross-trait genetic relationships are, however, subject to dynamic changes during development. We investigated the continuity of genetic overlap between ASD and ADHD symptoms in a general population sample during childhood and adolescence. We also studied uni- and cross-dimensional trait-disorder links with respect to genetic ADHD and ASD risk. METHODS: Social-communication difficulties (N = 5551, Social and Communication Disorders Checklist, SCDC) and combined hyperactive-impulsive/inattentive ADHD symptoms (N = 5678, Strengths and Difficulties Questionnaire, SDQ-ADHD) were repeatedly measured in a UK birth cohort (ALSPAC, age 7 to 17 years). Genome-wide summary statistics on clinical ASD (5305 cases; 5305 pseudo-controls) and ADHD (4163 cases; 12,040 controls/pseudo-controls) were available from the Psychiatric Genomics Consortium. Genetic trait variances and genetic overlap between phenotypes were estimated using genome-wide data. RESULTS: In the general population, genetic influences for SCDC and SDQ-ADHD scores were shared throughout development. Genetic correlations across traits reached a similar strength and magnitude (cross-trait rg = 1, pmin = 3 x 10(-4)) as those between repeated measures of the same trait (within-trait rg = 0.94, pmin = 7 x 10(-4)). Shared genetic influences between traits, especially during later adolescence, may implicate variants in K-RAS signalling upregulated genes (p-meta = 6.4 x 10(-4)). Uni-dimensionally, each population-based trait mapped to the expected behavioural continuum: risk-increasing alleles for clinical ADHD were persistently associated with SDQ-ADHD scores throughout development (marginal regression R(2) = 0.084%). An age-specific genetic overlap between clinical ASD and social-communication difficulties during childhood was also shown, as per previous reports. Cross-dimensionally, however, neither SCDC nor SDQ-ADHD scores were linked to genetic risk for disorder. CONCLUSIONS: In the general population, genetic aetiologies between social-communication difficulties and ADHD symptoms are shared throughout child and adolescent development and may implicate similar biological pathways that co-vary during development. Within both the ASD and the ADHD dimension, population-based traits are also linked to clinical disorder, although much larger clinical discovery samples are required to reliably detect cross-dimensional trait-disorder relationships.

We conducted this study to describe the aggressive mode of preschool children with ASD and examine the associations between specific aggressive behaviors and two treatable factors: sleep problems and attention deficit hyperactivity disorder (ADHD) symptoms. In total, 577 typically developing (TD) children and 490 children with ASD were investigated in this study. The Institute for Basic Research – Modified Overt Aggression Scale (IBR-MOAS) was used to assess aggressive behaviors. Children's social impairments, sleep problems and ADHD symptoms were also measured with specific scales. The total IBR-MOAS score was significantly higher (worse) in the TD group [4.47 (5.36)] than in the ASD group [3.47 (5.63), P?=?0.004]. The aggressive modes differed between groups: when compared with each other, the TD group received higher scores on Verbal and Physical Aggression Toward Others (all P?0.01), while the ASD group had higher scores on Physical Aggression Against Self (P?=?0.006). The linear regression model demonstrated that the aggressive behaviors of children with ASD were significantly associated with two treatable factors: sleep problems and ADHD symptoms. These findings have substantial clinical implications: treatment of these two risk factors may be helpful in managing aggressive behavior in children with ASD.

The aim of our study was to evaluate the common or distinctive clinical features between ASD and ADHD in order to identify possible different phenotypes that could have a clinical value. We enrolled 181 subjects divided into four diagnostic groups: ADHD group, ASD group, ASD+ADHD group (that met diagnostic criteria for both ASD and ADHD), and control group. Intelligent quotient (IQ), emotional and behavior problems, ADHD symptoms, ASD symptoms, and adaptive behaviors were investigated through the following test: Wechsler Intelligence Scale for Children, Wechsler Preschool and Primary Scale of Intelligence or Leiter International Performances Scale Revised, Child Behavior Checklist, Conners' Rating Scales-Revised, SNAP-IV Rating Scale, the Social Communication Questionnaire, Vineland Adaptive Behavior Scales. The ASD+ADHD group differs from ADHD or ASD in some domains such as lower IQ mean level and a higher autistic symptoms severity. However, the ASD+ADHD group shares inattention and hyperactivity deficit and some emotional and behavior problems with the ADHD group, while it shares adaptive behavior impairment with ASD group. These findings provide a new understanding of clinical manifestation of ASD+ADHD phenotype, they may also inform a novel treatment target.
