Abstract
45 patients (aged 16-73 yrs) with closed head injuries were followed up 6 mo postinjury with magnetic resonance imaging (MRI) and neuropsychological assessments. Ss were tested on visual and verbal measures of short-term memory and learning: pattern span, pattern learning, path span, path learning, digit span, and digit learning. Visual memory for patterns and paths was tested using a recall procedure. Compared with 22 controls (aged 15-70 yrs), Ss were significantly impaired on pattern span. Ss were also significantly impaired on measures of path learning and digit learning. Performance on the visual memory tasks was related to a rating of ventricular enlargement derived from MRI. It appears that diffuse damage remains of importance in predicting neuropsychological impairment in head injury.
