Factors affecting recovery after head injury in children
The present study examined the effects of severity, type of injury, age, and rate of change of developing memory functions on short-term recovery of memory after pediatric closed head injury (CHI). Memory was assessed utilizing verbal and nonverbal selective reminding tests and a recognition memory test. Subjects included 34 CHI subjects and 26 comparable controls. The results suggest the following conclusions: 1) No specific severity measure predicted memory impairment uniquely; 2) Left focal lesions resulted in poorer memory performance than right focal lesions, and verbal memory tended to be more affected in left-lesioned and bilateral/diffuse subjects; 3) Greater severity of injury increased memory impairment but younger age did not, except on the CRM false alarm score. This study points to the importance of considering both injury and developmental factors when studying the recovery of children after CHI.
