Motor Abnormalities

Autism is a neurodevelopmental disorder typically assessed and diagnosed through observational analysis of behavior. Assessment exclusively based on behavioral observation sessions requires a lot of time for the diagnosis. In recent years, there is a growing need to make assessment processes more motivating and capable to provide objective measures of the disorder. New evidence showed that motor abnormalities may underpin the disorder and provide a computational marker to enhance assessment and diagnostic processes. Thus, a measure of motor patterns could provide a means to assess young children with autism and a new starting point for rehabilitation treatments. In this study, we propose to use a software tool that through a smart tablet device and touch screen sensor technologies could be able to capture detailed information about children’s motor patterns. We compared movement trajectories of autistic children and typically developing children, with the aim to identify autism motor signatures analyzing their coordinates of movements. We used a smart tablet device to record coordinates of dragging movements carried out by 60 children (30 autistic children and 30 typically developing children) during a cognitive task. Machine learning analysis of children’s motor patterns identified autism with 93% accuracy, demonstrating that autism can be computationally identified. The analysis of the features that most affect the prediction reveals and describes the differences between the groups, confirming that motor abnormalities are a core feature of autism.

INTRODUCTION: Autism Spectrum Disorder is a neurodevelopmental disorder characterized mainly by deficits in social and communication patterns. Aberrant gene environment interactions during fetal development leads to formation of minor physical anomalies such as abnormal palmar creases commonly seen in autism spectrum disorder. AIM: To compare the prevalence of abnormal palmar creases in children with autism spectrum disorder and typically developing children. METHODOLOGY:It was a case controlled cross sectional study conducted in departments of Psychiatry and Pediatrics of Pt. B.D. Sharma, PGIMS Rohtak. Fifty children of age 4-16 years with diagnosis of autism spectrum disorder (case group) and fifty typically developing children (control group) were recruited. A digital camera of 13 megapixels was used to click photographs of the palms of children. Palmar crease patterns of fifty children with diagnosis of autism spectrum disorder were compared with the control group. RESULTS:The prevalence of abnormal palmar creases in case group was higher (47%) than in control group (14%).The prevalence of Simian crease in case group was double (22%) as compared to one in control group i.e. 11%. The prevalence of Sydney crease in case group was 21%, while in control group it was only 3%. The prevalence of Suwon crease in case group was 4%,while it was not seen in control group. CONCLUSION:Children with abnormal palmar creases help in early screening of neurodevelopmental disorders such as autism spectrum disorder helping in early management of these children leading to better outcomes and alleviation of parental stress and burden

The Relationship

The aim of this study was to examine the level of a sense of empowerment among mothers and fathers of children with autism. The relationship between a sense of empowerment and socio-demographic variables characterising the respondents including the parents was also analysed. Among the participants, there were 74 parents of autistic children (39 mothers, 35 fathers), 77 parents of children with Down syndrome (40 mothers, 37 fathers) as well as 80 parents of typically developing children (40 mothers, 40 fathers). Two statistical tools, namely the non-parametric Mann-Whitney U test and Kruskal-Wallis test, were employed in this study. The results show a higher level of a sense of empowerment when it comes to the evaluation of own knowledge and competences in mothers of autistic children than in mothers of children with Down syndrome, contrary to fathers of autistic children whose level of a sense of empowerment is lower within the said scope compared with fathers of children with Down syndrome.

Motor Abnormalities

Motor abnormalities are highly prevalent in children with autism spectrum disorder and are strongly predictive of adaptive functioning. Despite the documented sex bias in the prevalence of the disorder, the impact of sex differences on motor abnormalities has been overlooked. The goal of this study was to investigate differences in the motor profile of boys and girls with autism spectrum disorder aged 3–11 years using a multimethod approach. Ninety-eight children with autism spectrum disorder and 98 typically developing children were assessed using the Movement Assessment Battery for Children 2, the Developmental Coordination Disorder Questionnaire, and the kinematic analysis of a reach-to-drop task. Results from principal components analysis on reach-to-drop-dependent measures indicated four components, accounting for kinematic parameters of the motor task. Irrespective of sex, children with autism spectrum disorder showed worse scores on Movement Assessment Battery for Children 2 and Developmental Coordination Disorder Questionnaire subscales than typically developing children. Interestingly, a diagnosis-by-sex interaction was found on a kinematic feature measured in the last part of the movement, with girls with autism spectrum disorder presenting altered motor anticipation. Although preliminary, these findings suggested that sex-related nuances in motor functioning of children with autism spectrum disorder could be insufficiently captured by existing motor measures. Lay abstract Motor peculiarities are often reported in children with autism spectrum disorder and may predict subsequent adaptive functioning and quality of life. Although the sex bias in the prevalence of the disorder is well documented, little is known about differences in motor profile in males and females with autism spectrum disorder. Our goal was to study differences in motor functioning of boys and girls with autism spectrum disorder aged 3–11 years compared with typically developing children. Their motor performances were evaluated using a multimethod approach, including standardized motor tests, caregiver reports, and a detailed motion capture analysis of a simple reach-to-drop movement. We found that, irrespective of sex, children with autism spectrum disorder had worse scores than typically developing children on standardized tests and on caregiver reports. Interestingly, girls with autism spectrum disorder, but not boys, presented altered motor anticipation in reach-to-drop. Our findings emphasize the need for more sex-specific assessment of motor function in autism spectrum disorder.

AbstractFailure to develop prospective motor control has been proposed to be a core phenotypic marker of autism spectrum disorders (ASD). However, whether genuine differences in prospective motor control permit discriminating between ASD and non-ASD profiles over and above individual differences in motor output remains unclear. Here, we combined high precision measures of hand movement kinematics and rigorous machine learning analyses to determine the true power of prospective movement data to differentiate children with autism and typically developing children. Our results show that while movement is unique to each individual, variations in the kinematic patterning of sequential grasping movements genuinely differentiate children with autism from typically developing children. These findings provide quantitative evidence for a prospective motor control impairment in autism and indicate the potential to draw inferences about autism on the basis of movement kinematics.

The objective of this study was to compare experiential grammar in the narrative discourse of thirty typically developing Thai children and thirty Thai children with autism in elementary grades 1 to 3. Data was compiled by asking subjects to tell a narrative discourse from a wordless storybook "A Boy, a Dog, and a Frog” (Mayer 1967). Data was analyzed based on the Systemic Functional Linguistics approach and focused on experiential mode of meaning concerned with the system of Transitivity. The results revealed that children with autism used fewer clause complexes and clause simplexes than typically developing children. For the system of Transitivity, it was found that children with autism used less modified nominal groups as the Participant especially in grade 2 and 3 and they used a smaller number and less variety of process types; used a lower percentage of mental, behavioral and verbal processes; and used a lower percentage of serial verb constructions. Children with autism, especially those in grades 2 and 3, used a smaller variety of circumstance types; and used a lower percentage of clauses with complex circumstances.

Eye gaze direction and expression intensity effects on emotion recognition in children with autism disorder and typically developing children were investigated. Children with autism disorder and typically developing children identified happy and angry expressions equally well. Children with autism disorder, however, were less accurate in identifying fear expressions across intensities and eye gaze directions. Children with autism disorder rated expressions with direct eyes, and 50% expressions, as more intense than typically developing children. A trend was also found for sad expressions, as children with autism disorder were less accurate in recognizing sadness at 100% intensity with direct eyes than typically developing children. Although the present research showed that children with autism disorder are sensitive to eye gaze direction, impairments in the recognition of fear, and possibly sadness, exist. Furthermore, children with autism disorder and typically developing children perceive the intensity of emotional expressions differently.

Abstract Background: Previous research studies have demonstrated abnormalities in the metabolism of mothers of young children with autism.Method: Metabolic analysis was performed on blood samples from 30 mothers of young children with Autism Spectrum Disorder (ASD-M) and from 29 mothers of young typically-developing children (TD-M). Targeted metabolic analysis focusing on the folate one-carbon metabolism (FOCM) and the transsulfuration pathway (TS) as well as broad metabolic analysis were performed. Statistical analysis of the data involved both univariate and multivariate statistical methods.Results: Univariate analysis revealed significant differences in 5 metabolites from the folate one-carbon metabolism and the transsulfuration pathway and differences in an additional 48 metabolites identified by broad metabolic analysis, including lower levels of many carnitine-conjugated molecules. Multivariate analysis with leave-one-out cross-validation allowed classification of samples as belonging to one of the two groups of mothers with 93% sensitivity and 97% specificity with five metabolites. Furthermore, each of these five metabolites correlated with 8-15 other metabolites indicating that there are five clusters of correlated metabolites. In fact, all but 5 of the 50 metabolites with the highest area under the receiver operating characteristic curve were associated with the five identified groups. Many of the abnormalities appear linked to low levels of folate, vitamin B12, and carnitine-conjugated molecules.Conclusions: Mothers of children with ASD have many significantly different metabolite levels compared to mothers of typically developing children at 2-5 years after birth.
