In this unique study a clinical cohort of children with severe TBI was followed for many years after injury. Most cognitive deficits were found in the early phase of rehabilitation. Most children did improve on cognitive functioning (40%) during the first year after their injury, whereas at follow-up most children had not changed. At follow-up, more than half of the children (54%) attended a regular school or had a regular job, corresponding to their age and pre-morbid functioning.
