Wechsler Memory Scale-Revised in closed head injury

This study was undertaken to determine the ability of the Wechsler Memory Scale-Revised (WMS-R) to differentiate a group of closed head injury patients from a group of controls and determine how injury severity and attentional deficits are associated with WMS-R performance. The relationship of WMS-R performance to everyday memory also was assessed. The head injured group performed more poorly than controls on all five WMS-R indices and exhibited greater impairments on tasks that measure retention. In the original sample only the Visual Memory Index correlated with injury severity; in a larger sample, all four memory indices correlated modestly with injury severity. Patients who performed more poorly on the WMS-R also received poorer ratings on an independent assessment of everyday memory.
