39 Neurodevelopmental Complexity of a Patient with Perinatal Right Middle Cerebral Artery Stroke and Infantile Spasms

Abstract

Objective:A rich literature exists on cognitive changes related to focal injury in the adult brain. In contrast, the developing brains of children are less understood. In contrast to adult cases, 20% to 25% of perinatal strokes result in language disorder regardless of lesion lateralization. Existing literature suggests children with perinatal stroke may present with a range of executive functioning and visuospatial processing difficulties. Gross and fine motor challenges are also likely to occur. Furthermore, these children have an increased prevalence of autism spectrum disorder (ASD) and carry the highest risk for epilepsy. Despite growing research on neurodevelopmental profiles in patients with perinatal stroke, published literature is limited.Participants and Methods:Our study examines neurodevelopment of a 2-year-old, right-handed male with a history of perinatal ischemic right middle cerebral artery (MCA) stroke, infantile spasms, and left hemiparesis following right hemispherectomy for seizure management who underwent two neurodevelopmental evaluations at our medical center over approximately 3 years.Results:Findings from the patient’s evaluation with the Mullen Scales of Early Learning revealed overall cognitive ability in the low average range (SS = 89, 23rd percentile); however, notable variability was seen in his performance. His receptive language was average (SS = 98, 45th %tile) and consistent with previous evaluation results, and he has made gains in visual reception (from SS = 75, 5th %tile to SS = 91, 27th %tile) and expressive language (from SS = 55, 0.1st %tile to SS = 70, 2nd %tile). In addition, his gross motor was exceptionally low (SS = 55, 0.1st %tile) and consistent with previous evaluation results. Fine motor was low average (SS = 84, 14th %tile).Conclusions:Our patient showed cognitive gains in language and visual reception since his prior evaluation despite history of right MCA stroke and right hemispherectomy. Improvements are likely due to a combination of early brain plasticity and intensive therapies he has received. Consistent with published findings in this population, he experienced seizures associated with his stroke. Our results add to the limited literature on neurodevelopmental challenges associated with perinatal stroke and progress that can be made when appropriate supports are provided early and consistently.
