Conventional methodology to investigate cognitive impairment after coronary artery bypass graft (CABG) surgery leaves unclear the potential for pre-existing cognitive deficits to influence outcome. Individuals with pre-existing deficits may be more vulnerable to the effects of CABG, hence biasing the results of a typical prospective trial if account is not taken of their state. The present stud...

introduction: age-related decreases in cognitive functions such as executive functions are a common phenomenon. cognitive rehabilitation with two main approaches, compensation and remediation, is used to help elderlies coping with these deficits. despite reported benefits, there are doubts on the efficacy of each of these approaches. we tried to provide effective computerized cognitive tasks as...
