However, no studies have specifically examined the associations between ASD symptoms, measures of social and emotional functioning and limbic system white matter microstructure. Tractography on the cingulum, uncinate fasciculus and fornix were performed for 151 children with (N?=?78) and without (N?=?73) ADHD. Participants in the ADHD group who scored 11 or above on the Social Communication Questionnaire were classified as the ADHD?+?ASD group (N?=?16). Significant differences in mean cingulum FA were present between the control group and the ADHD (all) group, however, no significant differences were seen between the ADHD and ADHD?+?ASD groups. Despite this, significant associations were seen between mean FA of the left cingulum and emotional problems for the ADHD?+?ASD group. Results give greater insights into the specific biological basis of emotional problems in the ADHD?+?ASD group, indicating that the cingulum may play a role.

Effortful and Automatic Information Processing in Boys with ADHD and Specific Learning Disorders / Philip L. HAZELL in Journal of Child Psychology and Psychiatry, 40-2 (February 1999)

ADHD and LD/ADHD subjects did not differ from controls at baseline or under feedback and reward conditions, suggesting that they were investing similar levels of mental effort in the tasks. The LD group had a superior performance in the effortful task and an inferior performance in the automatic task compared with the other groups at baseline. The data suggest a potential method of distinguishing primary LD from learning difficulties that occur secondary to ADHD.

Relationship Between Executive Functioning and Symptoms of Attention-Deficit/Hyperactivity Disorder and Autism Spectrum Disorder in 6–8 Year Old Children / Rachel Jane NEELY in Journal of Autism and Developmental Disorders, 46-10 (October 2016)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 46-10 (October 2016) . - p.3270-3280 Titre : Relationship Between Executive Functioning and Symptoms of Attention-Deficit/Hyperactivity Disorder and Autism Spectrum Disorder in 6–8 Year Old Children Type de document : Texte imprimé et/ou numérique Auteurs : Rachel Jane NEELY, Auteur ; Jessica Leigh GREEN, Auteur ; Emma SCIBERRAS, Auteur ; Philip L. HAZELL, Auteur ; Vicki ANDERSON, Auteur Article en page(s) : p.3270-3280 Langues : Anglais (eng) Mots-clés : Attention-deficit/hyperactivity disorder  Autism spectrum disorder  Comorbidity  Child  Executive function Index. décimale : PER Périodiques Résumé : This study examined relationships between executive functioning (EF) and ADHD/ASD symptoms in 339 6–8 year-old children to characterise EF profiles associated with ADHD and ADHD + ASD. ADHD status was assessed using screening surveys and diagnostic interviews. ASD symptoms were measured using the Social Communication Questionnaire, and children completed assessments of EF. We found the EF profile of children with ADHD + ASD did not differ from ADHD-alone and that lower-order cognitive skills contributed significantly to EF. Dimensionally, ASD and inattention symptoms were differentially associated with EF, whereas hyperactivity symptoms were unrelated to EF. Differences between categorical and dimensional findings suggest it is important to use both diagnostic and symptom based approaches in clinical settings when assessing these children’s functional abilities.
