Under the leadership of Amery Treble-Barna, PhD, researchers of this lab aim to develop a comprehensive understanding of the multitude of factors that interact to influence neurobehavioral recovery from pediatric traumatic brain injury (TBI), and to use this information to improve patient outcomes.
TBI is a leading cause of morbidity and mortality in childhood. The scientific evidence available to guide prognosis, management, and treatment is disproportionately low relative to TBI’s medical and societal burden. Children sustaining moderate to severe TBI often demonstrate neurobehavioral impairments that hamper their long-term functioning. Current prediction models, however, explain only about 35% of variance in these outcomes. Without the identification of additional factors influencing recovery, this unexplained heterogeneity will remain one of the most critical barriers to accurate prognostication and to the development of evidence-based treatments for the neurobehavioral consequences of pediatric TBI.
Working from biopsychosocial and precision medicine frameworks, the Treble-Barna Lab is studying the effects of a variety of factors influencing neurobehavioral recovery from pediatric TBI, including:
The lab aims to use this knowledge to improve individual prognostication, predict response to rehabilitation, and identify novel targets for treatment development.
Funded by the National Institute of Child Health & Human Development, the Treble-Barna Lab is currently enrolling children with TBI or orthopedic injuries into a study examining the influence of epigenetic factors on neurobehavioral recovery. Over the last decade, the field of epigenetics has become central to studying the modulation of genetic phenotypes by environmental factors. Broadly defined, epigenetics involves biochemical processes that regulate gene expression without altering the corresponding primary DNA sequence. Through epigenetic processes, the social and biological environment of an individual impacts when and to what extent genes are expressed within each cell type.
The overarching goal of this study is to investigate an epigenetic biomarker involved in both childhood adversity and post-injury neuroplasticity to better understand heterogeneity in neurobehavioral outcomes following TBI.
One factor that may explain differences in pediatric TBI recovery is inconsistent use of the broad variety of available rehabilitation services; however, this has not been confirmed because no scientifically rigorous, comprehensive, standardized, or validated measure of rehabilitation utilization currently exists. TBI rehabilitation encompasses a wide range of multidisciplinary services spanning the care continuum from the ICU to the community. Utilization of rehabilitation services following pediatric TBI is highly variable. Our long-term goal is to examine whether variance in rehabilitation utilization accounts for some of the unexplained heterogeneity in outcomes following pediatric TBI. If we can reduce heterogeneity in our models of TBI recovery, we can provide more accurate prognostication and improve our ability to test the efficacy of treatments. As a critical first step, we are developing, refining, and conducting initial validation of a caregiver-report measure of rehabilitation utilization, the Rehabilitation Utilization Measure (RUM). We are combining qualitative and quantitative methods to engage caregiver, clinician, and scientist stakeholders in measure development and refinement and conducting initial measure validation.
Clinical neuropsychologists aim to understand the nature of cognitive and behavioral problems in children with TBI by conducting comprehensive neuropsychological evaluations, to identify evidence-based interventions and environmental accommodations tailored to the unique needs of each child. This also requires educating and empowering the child’s caregivers, medical providers, and school personnel to follow through with the recommended services. To our knowledge, no studies have examined the impact of the neuropsychological evaluation on reducing unmet/unrecognized needs or increasing service utilization in children with TBI. With funding support from the American Academy of Clinical Neuropsychology Foundation, the Treble-Barna Lab is currently enrolling children with TBI into a study comparing unmet/unrecognized needs and service utilization in children who did and did not receive neuropsychological evaluation within 1 year post-injury.
