Study investigated whether cognitive outcome and degree of recovery in civilian penetrating traumatic brain injury (TBI) due to gunshot can be distinguished from that of non-penetrating TBI due to motor vehicle accident. One hundred twenty-two matched survivors of penetrating and non-penetrating TBI were assessed with a brief neuropsychological test battery at inpatient rehabilitation, 1 year post-injury, and 2 years post-injury. Results indicated significant differences in cognitive outcome between penetrating and non-penetrating TBI, with these differences varying across time after injury. Compared to non-penetrating TBI, penetrating TBI was distinguished by better verbal learning, better fine motor dexterity, and possibly poorer attention during the first weeks post-injury, and better fine motor dexterity and poorer word generation at 1 and 2 year post-injury. Nevertheless, the degree of recovery over the first 2 years appeared to be quite similar for penetrating and non-penetrating injuries.
