“…To our knowledge, it is unknown whether the oculomotor control atypicalities found in DCD may be explained or influenced by the presence of a co-occurring neurodevelopmental disorder (see Smits-Engelsman, Jover, Green, Ferguson, & Wilson, 2017). Indeed, co-occurrence between neurodevelopmental disorders is a very common condition.…”

“…For instance, developmental coordination disorder co-occurs with other developmental disorders in 50% of cases. In instances of comorbidity, the number and intensity of needs (and therefore unmet needs) is often amplified (Smits-Engelsman et al, 2017). A limitation of current studies is an almost complete focus on children (Jongmans et al, 2003; Kirby and Sugden, 2007), including a 2001 systematic review of 176 publications and 125 groups of children (Geuze et al, 2001).…”

In Florida, the Agency for Persons with Disabilities provides waivers for adults with the following types of disabilities: intellectual disability, autism spectrum disorder, cerebral palsy, spina bifida, Down syndrome, and Prader-Willi syndrome. This review examined the peer-reviewed literature to indicate and assess the common needs for individuals with intellectual and developmental disabilities. Current models of service delivery, the efficacy of these services, and remaining gaps in the need fulfillment of individuals within the six diagnostic categorizations of interest were examined. Severity level within each diagnostic category was plotted on a matrix according to whether the needs of individuals were minimal, moderate, severe, or universal. The study found that sexual health education, socialization, and adult-focused medical care are universal needs among the six conditions. The study indicates that health-care professionals must work toward addressing the many unmet needs in comprehensive life span care services for adult individuals with neurodevelopmental disorders.

“…The NICHQ Vanderbilt Assessment Scale-Parent (VADRS-P) was used to assist in determining the risk of Attention Deficit Hyperactivity Disorder (ADHD) in children aged 6–12 years and has demonstrated utility in a pediatric population ( Langberg et al, 2010 ; Kiker, 2011 ; Limbers et al, 2011 ; Becker et al, 2012 ). The 18 ADHD questions were used to screen for inclusion, due to the high co-morbidity of DCD and ADHD ( Gillberg, 2003 ; Martin et al, 2006 ; Dewey and Bernier, 2016 ; Smits-Engelsman et al, 2017 ) and the attentional requirements and specificity of the current study. There were no children excluded based on this questionnaire.…”

IntroductionChildren with Developmental Coordination Disorder (DCD) demonstrate deficits in predictive motor control and aspects of cognitive control compared with their typically developing (TD) peers. Adjustment to dynamic environments depends on both aspects of control and the deficits for children with DCD may constrain their ability to perform daily actions that involve dual-tasking. Under the assumption that motor-cognitive integration is compromised in children with DCD, we examined proportional dual-task costs using a novel locomotor-cognitive dual-task paradigm that enlisted augmented reality. We expect proportional dual-task performance costs to be greater for children with DCD compared to their TD peers.MethodsParticipants were 34 children aged 6–12 years (16 TD, 18 DCD) who walked along a straight 12 m path under single- and dual-task conditions, the cognitive task being visual discrimination under simple or complex stimulus conditions presented via augmented reality. Dual-task performance was measured in two ways: first, proportional dual-task costs (pDTC) were computed for cognitive and gait outcomes and, second, within-trial costs (p-WTC) were measured as the difference on gait outcomes between pre- and post-stimulus presentation.ResultsOn measures of pDTC, TD children increased their double-limb support time when walking in response to a dual-task, while the children with DCD increased their locomotor velocity. On p-WTC, both groups increased their gait variability (step length and step width) when walking in response to a dual-task, of which the TD group had a larger proportional change than the DCD group. Greater pDTCs on motor rather than cognitive outcomes were consistent across groups and method of dual-task performance measurement.DiscussionContrary to predictions, our results failed to support dramatic differences in locomotor-cognitive dual-task performance between children with DCD and TD, with both groups tending to priorities the cognitive over the motor task. Inclusion of a within-trial calculation of dual-task interference revealed an expectancy effect for both groups in relation to an impending visual stimulus. It is recommended that dual-task paradigms in the future continue to use augmented reality to present the cognitive task and consider motor tasks of sufficient complexity to probe the limits of performance in children with DCD.
