Abstract

Sixty-four traumatically brain injured patients were divided into three groups. Patients in Group I overestimated their behavioral competencies. Patients in Group II showed behavioral ratings similar to relatives' reports concerning behavioral competencies. Patients in Group III underestimated their behavioral competencies. Group I patients had greater evidence of bilateral and multiple-site lesions than group II and III patients. Speed of left-hand finger tapping was also worse in Group I than groups II and III, but other standard neuropsychologic test findings failed to separate the groups. Specific brain lesion sites were not related to group membership. Impaired awareness of behavioral limitations after traumatic brain injury may be related to neuropsychologic changes not measured by standard tests. Bilateral impairment of heteromodal cortex may be important to this phenomenon when it exists several months or years postinjury.
