Jayashankar A, Bynum B, Butera C, Kilroy E, Harrison L, Aziz-Zadeh L. Connectivity differences between inferior frontal gyrus and mentalizing network in autism as compared to developmental coordination disorder and non-autistic youth. Cortex 2023; 167:115-131. [PMID: 37549452 PMCID: PMC10543516 DOI: 10.1016/j.cortex.2023.06.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 06/08/2023] [Accepted: 06/15/2023] [Indexed: 08/09/2023]
Abstract
Prior studies have compared neural connectivity during mentalizing tasks in autism (ASD) to non-autistic individuals and found reduced connectivity between the inferior frontal gyrus (IFG) and mentalizing regions. However, given that the IFG is involved in motor processing, and about 80% of autistic individuals have motor-related difficulties, it is necessary to explore if these differences are specific to ASD or instead similar across other developmental motor disorders, such as developmental coordination disorder (DCD). Participants (29 ASD, 20 DCD, 31 typically developing [TD]; ages 8-17) completed a mentalizing task in the fMRI scanner, where they were asked to think about why someone was performing an action. Results indicated that the ASD group, as compared to both TD and DCD groups, showed significant functional connectivity differences when mentalizing about other's actions. The left IFG seed revealed ASD connectivity differences with the: bilateral temporoparietal junction (TPJ), left insular cortex, and bilateral dorsolateral prefrontal cortex (DLPFC). Connectivity differences using the right IFG seed revealed ASD differences in the: left insula, and right DLPFC. These results indicate that connectivity differences between the IFG, mentalizing regions, emotion and motor processing regions are specific to ASD and not a result of potentially co-occurring motor differences.

Cognitive Profiles of Children with Low Motor Performance: A Contribution to the Validation of the WPPSI-IV. CHILDREN 2022; 9:children9050619. [PMID: 35626796 PMCID: PMC9139465 DOI: 10.3390/children9050619] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 04/19/2022] [Accepted: 04/22/2022] [Indexed: 11/16/2022]
Abstract
(1) Background: Developmental Coordination Disorder (DCD) is a common developmental disorder of preschool age. Children often show cognitive deficits in addition to motor problems. Various studies point in particular to problems in visual perception, working memory and processing speed. In this context, it is investigated whether the Wechsler Preschool and Primary Scale-IV (WPPSI-IV) is a suitable instrument for mapping these deficits in a valid and economical way. (2) Methods: The WPPSI-IV profiles of children with DCD (n = 12), below-average motor performance (n = 22) and a control group (n = 32) were compared. (3) Results: Children with DCD achieved significantly poorer test performance in the primary indices Verbal Comprehension, Visual Spatial, Processing Speed and Full Scale compared to a control group. Children with below-average motor skills, on the other hand, do not differ from the children in the control group. (4) Conclusions: The WPPSI-IV is a suitable instrument for diagnosing cognitive deficits in the context of DCD. The Fluid Reasoning and Verbal Comprehension indices should be used as a supplement to assess cognitive performance levels.

Fastame MC. The contribution of motor functions to academic achievement in primary school: State of the art and future directions. SCHOOL PSYCHOLOGY INTERNATIONAL 2020. [DOI: 10.1177/0143034320954494] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022]
Abstract
This review is intended to point out the role played by motor skills proficiency in the academic achievement of typically and atypically developing pupils who are attending primary school. First, the interplay between motor and cognitive development will be presented. Next, the cognitive phenotype, not yet deeply investigated, of a neurodevelopmental condition associated with the atypical development of motor functions (known as Developmental Coordination Disorder) will be illustrated. Thus, the contribution of motor functions to academic learning and the impact of motor difficulties for pupils attending primary school will be discussed. In addition, the importance of developing observational tools to be used in educational settings and the need for effective interventions designed to empower motor functioning and academic achievement of atypically developing pupils with motor deficits will be highlighted. Finally, future directions within the educational agencies for the early detection of the atypically developing motor trajectories and their treatment will be traced.
