Interhemispheric motor interactions in hemiparetic children with perinatal stroke: Clinical correlates and effects of neuromodulation therapy

Perinatal ischemic stroke (PS) is the occlusion of arteries or veins that results in cerebral damage between 20 weeks gestation and 28 days of life (Raju, 2007; Nelson and Lynch, 2004). PS is common, occurring in>1:3000 live births, and accounts for most hemiparetic cerebral palsy (CP) (Kirton and DeVeber, 2013). Children with PS-induced hemiparetic CP typically manifest motor asymmetry and early hand preference in the first 4-6 months of life (Kirton et al., 2010b). How the motor system develops following such early unilateral brain injury is increasingly defined by animal (Martin et al., 2007) and human (Eyre, 2007; Staudt, 2007) studies.

Group Abstract BACKGROUND AND OBJECTIVES: Neonatal arterial ischemic stroke (NAIS) can lead to long-term neurological consequences such as cerebral palsy (CP). The aim of this study was to evaluate the predictive value of acute diffusion-weighted imaging (DWI) for CP by analyzing stroke volume next to brain structure involvement. METHODS: We included 37 term-born infants with NAIS prospectively registered in a nationwide pediatric stroke registry. DWI was performed between 0 and 8 days (mean 3 days) after stroke manifestation. Participants were neurologically assessed at the age of 2 years. We calculated the ...

Group Abstract AIM: To investigate health-related quality of life (HRQOL) and manual ability five years after neonatal arterial ischemic stroke (NAIS). METHODS: Data was prospectively obtained by the Swiss Neuropaediatric Stroke Registry between 2000 and 2010. Two years after NAIS, cognitive and motor outcomes was assessed using the Bayley Scales of Infant Development (BSID-II). After 5 years, HRQOL was assessed with the KIDSCREEN-27 and manual ability with the ABILHAND-Kids. Manual ability and HRQOL were compared between children with and without cerebral palsy (CP) and HRQOL was correlated with manual abili...

Neonatal arterial ischemic stroke (NAIS) is a leading cause of cerebral palsy and lifelong disability. Diffusion-weighted imaging (DWI) has revolutionized diagnosis and facilitated outcome prognostication in acute NAIS. Diaschisis refers to changes in brain areas functionally connected but structurally remote from primary injury. We hypothesized that acute DWI can quantify cerebral diaschisis and is associated with outcome from NAIS.

This study demonstrates that combination therapy is more effective than single therapy with either hUCBC or EPO for neurological recovery from subacute stroke. The common pathway underlying hUCBC and EPO treatment requires further study. Introduction Stroke, caused by the disruption of cerebral blood flow, is a leading cause of death and major disability throughout the world (1). However, the therapeutic options to deal with stroke are limited. Despite efforts to develop new therapies for stroke, all treatments have thus far failed to show a clinical effect or are known to have potential toxic effects. Although intra...

CONCLUSIONS: Absent SEP combined with continuous EEG background in near-term neonates indicates an MCA stroke and a high risk for cerebral palsy. SIGNIFICANCE: EEG-SEP offers a bedside method for diagnostic screening and a reliable prediction of neuromotor outcome in neonates suspected of having a stroke.

Background: Perinatal stroke (PS), the leading cause of hemiparetic cerebral palsy (HCP), typically results from occlusion of the middle cerebral artery (arterial ischemic stroke, AIS). Subsequent motor impairments last a lifetime and improving function is difficult. Transcranial direct-current stimulation (tDCS) is a form of non-invasive brain stimulation that may facilitate neuroplasticity and improve function. How current moves through the developing brain is different from adults. Modeling tDCS-induced electric fields (EF) is feasible but individual idiosyncrasies in lesion topology, white (WM) and grey matter (GM) arc...
