Key result
Severe traumatic brain injury in pre-school children was associated with greater acute attentional impairments compared to mild TBI, with significant recovery in attentional functioning over 6 months.
Cohort
Following severe traumatic brain injury, pre-school children experience acute attentional deficits but show differential recovery over 6 months, with improvements in arousal and motivation but persistent deficits in focused attention and impulsivity.
May inform acute attentional monitoring after severe preschool TBI; leaves open questions on targeted recovery interventions.
This study investigated attentional impairments and recovery in pre-school children following traumatic brain injury (TBI). Children aged between 3-8 years were assigned to two groups on the basis of severity of injury: (i) mild TBI and (ii) severe TBI. Children were evaluated at the acute stage postinjury (0-3 months) and again at 6 months on a range of standardized intellectual and attention measures. In addition, a specifically developed behavioural attention measure was employed. Results revealed a tendency for children with severe injuries to exhibit greater attentional impairments in the acute phase post-injury. In addition, children who sustained a severe TBI demonstrated significant recovery in attentional functioning over time. Results indicated differential recovery rates for separate components of attention. Both groups demonstrated a trend towards recovery of arousal and motivation over time, while focused attention, impulsivity and hyperactivity remained stable.

Kathleen Bakker (1999) conducted a cohort in Traumatic brain injury. Severe traumatic brain injury vs. Mild traumatic brain injury was evaluated on Attentional impairments and recovery. Severe traumatic brain injury in pre-school children was associated with greater acute attentional impairments compared to mild TBI, with significant recovery in attentional functioning over 6 months.
