Abstract |
Mild traumatic brain injury (mTBI) is a leading cause of injury among children, with approximately 15% of children experiencing a TBI prior to 15 years of age. Acutely, mTBI has been associated with a range of cognitive, physical, emotional and behavioural impairments. However, few studies have examined outcomes beyond five years post injury, long before the developmental process is complete and the full extent of any deficits may manifest. Our group had the unique opportunity to use data from a longitudinal birth cohort of 1265 children (Christchurch Health and Development Study) to examine the long term outcomes of early injury (0-5 years). Information about these children, including mTBI events, had been collected at birth, 4 months and at yearly intervals until age 16, and again at ages 18, 21 and 25 years. We found that even after statistical control for a wide range of child and family confounds, children who had been hospitalized for an mTBI had increased inattention/hyperactivity and conduct as rated by mothers and teachers over ages 7-13 years. Increased rates of psychiatric disorders were over 14-16 years for those injured in the preschool, including symptoms consistent with Attention Deficit/Hyperactivity Disorder (ADHD), Odds Ratio = 4.6, Conduct Disorder (CD), Odds Ratio = 5.6 and Substance Abuse (Odds Ratio = 9.1). Over ages 21-25 ongoing behaviour problems were assessed using self‐reported arrests, violent offenses and property offenses. Compared to non‐injured individuals, mTBI groups were more likely to be arrested, involved in property, and violent offences. We controlled for a wide range of factors and there was still clear evidence of ongoing problems for individuals who had experienced a mTBI compared to their non injured counterparts. These findings provide compelling evidence of long term psychosocial and psychiatric outcomes following mTBI. |
