| Abstract: | Deficits affecting Central Executive System (CES) of working memory (WM) are the main neuropsychological outcome after traumatic brain injury (TBI) and can also explain deficits in other domains, like divided attention, executive functions and long-term memory. For this reason we developed a rehabilitative program based on CES functions and we expected to find an improvement in WM as well as in those cognitive functions controlled by the CES.The experimental group was composed by 9 TBIs, selected for WM deficits, whereas the control group was composed by 6 TBIs, without WM deficits, but with speed processing deficits. All patients performed a cognitive training, based on PASAT (Gronwall & Wrightson, 1981)and two new versions of this task.The results showed in the experimental group an improvement in WM and in the cognitive functions controlled by the CES, whereas control patients did not show any improvement after the cognitive training. |
