Developmental coordination disorder in "apparently normal" schoolchildren born extremely preterm

Abstract

Apparently normal high-risk infants are at risk of motor dysfunction into their school years. Most of these could be identified at age 3.

Score for Neonatal Acute Physiology–II and Neonatal Pain Predict Corticospinal Tract Development in Premature Newborns

“…Pregnancy-induced hypertension was defined as the development of new arterial hypertension (blood pressure over 140/90 mmHg) during pregnancy, after 20 weeks gestation and without proteinuria. Given the association of PROM with poor motor outcome [8][9][10], we examined the role of chorioamnionitis as measured by placental histopathology, a more sensitive measure of intrauterine infection [25]. To measure early illness severity, we used SNAP-II during the first 24 hours of life; SNAP-II quantifies six physiological variables (blood pressure, temperature, PO 2 /fraction of inspired oxygen, serum pH, seizures, and urine output), with higher scores reflecting more disturbances in neonatal physiology [14].…”

“…Our aim was to explore in a prospective cohort of premature newborns serially studied with diffusion tensor imaging, the associations of established risk factors for motor impairment with development of the major motor pathway measured with diffusion tensor tractography. These risk factors include antenatal exposures, such as pregnancy-induced hypertension [6], gestational diabetes [7], and intrauterine inflammation [8][9][10], as well as male sex [11][12][13]. Putative perinatal and post-natal risk factors include early illness severity as measured by the Score of Neonatal Acute Physiology-Version II (SNAP-II) [14,15], infection [9,16,17], necrotizing enterocolitis [16,17], patent ductus arteriosus [18], chronic lung disease [18][19][20][21], and neonatal procedural pain [22].…”

Educational Outcomes in Extremely Preterm Children: Neuropsychological Correlates and Predictors of Attainment

“…Studies of school-age survivors have highlighted a significant excess of mild neuromotor dysfunction (Davis, Ford, Anderson, & Doyle, 2007;Fawke, 2007;Goyen & Lui, 2009;Wocadlo & Rieger, 2008), poor visuospatial processing (Marlow, Hennessy, Bracewell, & Wolke, 2007;Taylor, Burant, Holding, Klein, & Hack, 2002;Taylor, Klein, Minich, et al, 2000), and impairments in attention and executive functions (Aarnoudse-Moens, Smidts, Oosterlan, Duivenvoorden, & Weisglas-Kuperus, 2009; Anderson & Doyle, 2004;B. Bohm, Smedler, & Forssberg, 2004;Marlow et al, 2007;Mulder, Pitchford, Hagger, & Marlow, 2009).…”

Prevalence of motor problems in children with attention deficit hyperactivity disorder in Hong Kong

“…The prevalence of DCD in children born extremely premature (<29 weeks) or with extremely low birth weight (<1000 g) has been reported to be high, which was around 42% in one study. 29 A recent meta-analysis of studies in school-aged children with very low birth weight (VLBW)/very preterm reported an odds ratio (OR) of up to 8.66. 30 In our study, 6.5% and 10.8% of children had a history of prematurity or low birth weight, respectively, but none was born very preterm or with VLBW.…”
