Kids who experience a traumatic brain injury (TBI), even a mild one, have more emotional and behavioural problems than kids who do not, according to a study published in NeuroImage.
“These hits to the head are hard to study because much of it depends on recall of an injury since the impacts do not all require a visit to a doctor,” said study first author Daniel Lopez, a PhD candidate at Del Monte Institute for Neuroscience. “But being able to analyse longitudinal data from a large cohort and ask important questions like this gives us valuable information into how a TBI, even a mild one, impacts a developing brain.”
Researchers used MRI and behavioural data collected from thousands of children who participated in the Adolescence Brain Cognitive Development (ABCD) Study. They revealed children with a mild TBI experienced a 15-percent increased risk of an emotional or behavioural problem. The risk was the highest in children around ten years old. Researchers found that children who had a significant hit to the head but did not meet diagnostic criteria for a mild TBI also had an increased risk of these behavioural and emotional problems.
The University of Rochester Medical Center is one of 21 research sites collecting data for the National Institutes of Health ABCD Study. Since 2017, 340 children have been part of the 10-year study that is following 11 750 children through early adulthood. It looks at how biological development, behaviours, and experiences impact brain maturation and other aspects of their lives, including academic achievement, social development, and overall health.
Researchers hope future ABCD Study data will better reveal the impact these head hits have on mental health and psychiatric problems. “We know some of the brain regions associated with increased risk of mental health problems are impacted during a TBI,” said Ed Freedman, PhD, associate professor of Neuroscience and co-principal investigator of the ABCD Study at the University of Rochester. Freedman also led this study. “With more time and data, we hope to gain a better understanding of the long-term impact of even a mild TBI.”
