Abstract Background The purpose of this study was to describe clinical presentation, epilepsy, EEG, extent and site of the underlying cerebral lesion with special reference towards aetiologic background factors in a population-based group of children with hemiplegic cerebral palsy. Methods Forty-seven children of school- age, fulfilling the SPCE (Surveillance of Cerebral palsy in Europe)-criteria of hemiplegic cerebral palsy, identified via the Swedish cerebral palsy register, were invited and asked to participate in the study. Results Fifteen boys and six girls participated. Of the sixteen children born at term, five had no risk factors for cerebral palsy. Two out of five preterm children presented additional risk factors. Debut of motor impairment was observed in the first year of life in sixteen children. Age at diagnosis varied from 2 months to 6 years. Epilepsy was common and associated with grey- and white matter injury. Conclusions Recognizing the importance of risk factors for cerebral palsy, any child with these risk factors should be offered a check-up by a paediatrician or a paediatric neurologist. Thereby reducing diagnostic delay. Epilepsy is common in hemiplegic cerebral palsy and associated with grey- and white matter injury in this cohort.

Introduction: Cerebral palsy (CP) is the most common cause of motor disability in children, and chronic deficits are associated with white matter injury. Neonatal hypoxic-ischemic insults, an important cause of CP, induce oligodendrocyte apoptosis and impair normal myelin development. No CP treatments target myelination making regenerative medicine a promising research frontier. We investigated the effect of human embryonic-derived neural stem cell (NSC) treatment on oligodendrocytes and myelination following hypoxia-ischemia (HI). Methods: Neonatal Wistar rat pups underwent left CCA ligation followed by placement in 8% O2 at 37°C on post-natal day 7 (P7). Following T2w MRI on P9, immunosuppressed pups received intra-arterial transplant of 500k fLuc/eGFP transduced NSCs or saline on P10. BrdU was administered intraperitoneally from P11 - P18. In vivo bioluminescence images (BLI) were obtained 1 - 10 days (d) after injection. Myelination was evaluated using luxol fast blue (LFB) and myelin basic protein (MBP) staining 10 and 30 d after treatment. Oligodendrogenesis was quantified using BrdU staining in conjunction with Olig2, NG2, and CC1. RT-qPCR was performed on neonatal brain isolates and NSC mRNA. Luminex immunological assay was used to quantify NSC protein secretion. Functional recovery was assessed using the novel object recognition (NOR) task at P30. Results: Stroke size between groups was not significantly different 3, 10, and 30 d after treatment. BLI demonstrated significant NSC homing to the ischemic hemisphere days 1 - 7 (p=0.001) after transplant. Histology confirmed initial NSC localization to corpus callosum and cortex with migration into external capsule and corona radiata 30 d after transplant. NSC-treated pups had significantly more BrdU+ cells near the lateral ventricle (p=0.036) and in the corpus callosum (p=0.020) than controls. In addition to more Olig2+ and NG2+ cells in the striatum, NSC-treated pups had significantly more BrdU+/Olig2+ cells in the corpus callosum (p<0.05) than controls 30 d after treatment. LFB and MBP staining demonstrated greater myelination 10 and 30 d after treatment in corpus callosum (p=0.022, p<0.05) and striatum (p=0.017, p=0.001) of NSC-treated pups. Stat3 (2.82), IL-6 (1.48), and IL-6Rβ (1.73) mRNA was upregulated in the brains of NSC-treated pups. Proteomic and mRNA data confirm NSC expression of VEGF (17.9pg/mL, 4.35) and CXCL1 (3.6pg/mL, 10.27). NSC-treated pups performed better on NOR (p=0.016). Conclusions: Intra-arterial NSC transplant after hypoxia-ischemia results in NSC engraftment into white matter tracts, increased oligodendrocyte proliferation, and improved myelination. NSC-derived proteins may drive the distinct changes in gene expression occurring in the brain after NSC treatment and may mediate functional recovery via activation of endogenous self-repair mechanisms, including oligodendrogenesis.

Abstract Background Surveillance of cerebral palsy in Europe (SCPE) presents the first population-based results on neuroimaging findings in children with cerebral palsy (CP) using a magnetic resonance imaging classification system (MRICS). Method MRIs of children with CP born between 1999 and 2009 from 18 European countries were analyzed. MRICS identifies patterns of brain pathology according to timing during brain development which was analyzed with respect to CP subtypes and gestational age. Results MRIs or written reports from 3,818 children were available. The main clinical characteristics were similar to the 5,415 without such data. Most frequent was predominant white matter injury (49%), followed by predominant gray matter injury (21%). Maldevelopments were found in 11% of cases. Miscellaneous findings were present in 8.5% and normal findings in 10.6%. MRI patterns of children with unilateral spastic, bilateral spastic, and dyskinetic CP were mainly lesional (77, 71, and 59%, respectively), whereas children with ataxic CP had more maldevelopments, miscellaneous, and normal findings (25, 21, and 32%, respectively). In children born preterm, predominant white matter injury was most prevalent (80% in children born <32 weeks of gestation). Conclusion Analysis of MRI in the European CP database identified CP as a mainly lesional condition on a large population basis, maldevelopments were relatively uncommon. An exception was ataxic CP. Children born preterm mostly presented with a lesion typical for their gestational age (GA) at birth. The decreasing prevalence of CP in this group suggests that progress in perinatal and neonatal medicine may lead to a reduction of these lesions.
