Changes in short-term memory processes in patients with multiple sclerosis.
In this study we compared the performance of 39 multiple sclerosis (MS) patients with 28 age-, sex- and education-matched controls on both the Mini-Mental State Examination, a global cognitive assessment tool, and the Sternberg Short-Term memory scanning task, a standardized test of short-term memory (STM) processes. While the STM span of our MS patients did not differ from that of our controls, STM scanning time of the MS group was reliably slower than that of the controls and a significant correlation was observed between STM scanning time and duration but not severity of illness. Our results suggest that processing stages other than the manipulation of data within the STM buffer are also affected by MS.
