OBJECTIVES: To examine recovery of attention from 3 to 6 months postinjury; to
identify effects of injury severity and time since injury on performance; to
explore whether complex attention skills (eg, shifting, divided attention,
attentional control) are more vulnerable to traumatic brain injury (TBI), and
slower to recover than simple attention skills (eg, attentional capacity,
selective attention, sustained attention). DESIGN: Prospective longitudinal
investigation. PARTICIPANTS: A total of 205 school-aged children with TBI were
divided into groups according to injury severity (mild = 63%, moderate = 27%,
severe = 10%). SETTING: Emergency departments of 3 metropolitan children's
hospitals across Australia. MAIN MEASURES: Standardized clinical measures of both
simple and complex attention were administered at 3 months and 6 months
postinjury. RESULTS: Attention skills were vulnerable to the impact of TBI. More
severe injury affected attention skills most negatively. Significant recovery was
observed over time. There were few interaction effects, with severity groups
exhibiting similar levels of recovery over the 6 months post-TBI. No differences
in recovery trajectories were detected for simple and complex attention.
CONCLUSIONS: These findings have important clinical and educational implications,
suggesting that children with TBI, and particularly those with more serious
injuries, are most vulnerable to attention deficits in the acute stages
postinjury. It is important that schools and families are aware of these
limitations and structure expectations accordingly. For example, gradual return
to school should be considered, and in the early stages of recovery, children
should be provided with sufficient rest time, with reduced expectations for tasks
such as homework.
