Perinatal Stroke: Longitudinal Assessment of Infant Brain Organization and Recovery Through Neuroexcitability, Neuroimaging and Motor Development
This study will be a longitudinal multiple-visit observational study, done to identify possible bioindicators of recovery and repair of motor corticospinal pathways which may be targeted by future interventions in infants with perinatal stroke. 65 participants will be recruited and complete 1 visit at time point 1 (0-2 months), and 2 visits at each timepoints 2-5 with windows of +- 4 weeks (3-6 months, 12 months, 18 months and 24 months). Visits will consist of Magnetic Resonance Imaging (MRI) assessment during the child's natural sleep, Transcranial Magnetic Stimulation (TMS), and Motor Behavioral Assessments.
• Infants with corrected gestational age between term age and 24 months of age at study enrollment
• Radiologically-confirmed acute unilateral or bilateral brain lesions, including perinatal stroke, neonatal hemorrhagic or thrombotic stroke, involving the motor cortex and/or subcortical structures, and intracranial hemorrhage, involving the motor cortex and/or subcortical white matter, periventricular leukomalacia, and hypoxic-ischemic encephalopathy (HIE)
• English-speaking parent/legal guardian (able to provide consent)
