Developmental coordination disorder

Gohar Nikoghosyan-Bossen, Anne Lisbeth Hoffmann
In the absence of any known neurological condition or intellectual impairment, dyspraxia, also known as developmental coordination disorder, should be considered. Dyspraxia is the inability to plan, organize and execute movements. At all ages, dyspraxia can be congenital or acquired. While some learn to cope with their motor difficulties over the years, the majority will retain them as adults. Children with significant functional impairment should be identified and assessed as early as possible, since failure to address the motor and other commonly associated (co-morbid) features may have major consequences in adult life...

BACKGROUND: Dynactin p150Glued , the largest subunit of the dynactin macromolecular complex, binds to both microtubules and tubulin dimers through the N-terminal cytoskeleton-associated protein and glycine-rich (CAP-Gly) and basic domains, and serves as an anti-catastrophe factor in stabilizing microtubules in neurons. P150Glued also initiates dynein-mediated axonal retrograde transport. Multiple missense mutations at the CAP-Gly domain of p150Glued are associated with motor neuron diseases and other neurodegenerative disorders, further supporting the importance of microtubule domains (MTBDs) in p150Glued functions...

This pilot study is to investigate the influence of a developmental coordination disorder (DCD) comorbidity in a group of children with learning disability (LD). Reading and writing were assessed to investigate if the coexistence of a motor impairment can worsen writing quality, speed, and reading accuracy. A sample of 33 LD children (aged 7-11 years) was divided in two subgroups, on the base of their scores on the Movement Assessment Battery for Children: LD-only (n = 14) and LD with a comorbidity for DCD (LD-DCD, n = 19)...

BACKGROUND AND AIMS: One of the major concerns for Developmental Coordination Disorder (DCD) are the mental and physical consequences of the condition, especially as they relate to quality of life factors. Here, we examined health-related quality of life (HRQOL) in children with DCD, determined the association between two standardized parent reports, and compared HRQOL of our sample with DCD with the normative sample of each assessment for typically developing (TD) children and a sample of children with chronic health conditions...

PURPOSE: School-age children with Developmental Coordination Disorder (DCD) have poor health-related fitness (HRF), but little is known about when these deficits emerge. The purpose of this study was to determine if 4- and 5-year old children who meet the criteria for DCD exhibit poorer HRF than typically developing (TD) children, and if this relationship is mediated by vigorous physical activity (VPA) engagement. METHODS: Five-hundred and ninety-two children participated (age 5...

BACKGROUND: Adolescents with low motor competence participate less in physical activity and tend to exhibit decreased physical fitness compared to their peers with high motor competence. It is therefore essential to identify new methods of enhancing physical fitness in this population. Active video games (AVG) have been shown to improve motor performance, yet investigations of its impact on physical fitness are limited. The objective of this study was to examine the impact of the graded Wii protocol in adolescent girls with probable Developmental Coordination Disorder (p-DCD)...

How intrinsic and extrinsic signals are coordinated to regulate synaptic maturation and its timing is an important question for neurodevelopment and its disorders. Here, we investigated the influence of the neurotrophin BDNF on the developmental timing of a dendrite/synapse-related gene program controlled by Nuclear Factor One (NFI) in maturing cerebellar granule neurons (CGNs). BDNF accelerated the onset of NFI-regulated late-gene expression and NFI temporal occupancy in CGN cultures in a MEK5/ERK5-dependent manner...

Primary cilia are small, special cellular organelles that provide important sensory and signaling functions during the development of mammalian organs and coordination of postnatal cellular processes. Dysfunction of primary cilia are thought to be the main cause of ciliopathies, a group of genetic disorders characterized by overlapping developmental defects and prominent neurodevelopmental features. Although, disrupted cilia-linked signaling pathways have been implicated in the regulation of numerous neuronal functions, the precise role of primary cilia in the brain are still unknown...

Attention-deficit/hyperactivity disorder (ADHD) and generalized joint hypermobility (JH) are two separated conditions, assessed, and managed by different specialists without overlapping interests. Recently, some researchers highlighted an unexpected association between these two clinical entities. This happens in a scenario of increasing awareness on the protean detrimental effects that congenital anomalies of the connective tissue may have on human health and development. To review pertinent literature to identify possible connections between ADHD and GJH, special emphasis was put on musculoskeletal pain and syndromic presentations of GJH, particularly the hypermobile Ehlers-Danlos syndrome...

A puzzling observation in the study of autism spectrum disorder (ASD) in mouse models has been the deregulation of long-term synaptic depression (LTD), a form of experience-dependent synaptic plasticity, across brain areas and across syndromic and non-syndromic forms of autism. This review attempts to approach this phenomenon from a largely, but not exclusively, cerebellar perspective. Three potential consequences of LTD deregulation are discussed that are relevant for ASD phenotypes: resulting impairment of proper developmental synaptic pruning, impairment of motor coordination and motor learning, and impairment of the processing of sensory input...
