The main aim of the study is to determine the effectiveness of cognitive rehabilitation on the working memory recovery in people with mild cognitive impairment. The design of the study is a semi-experimental type with pre-test and post-test design of control and experimental groups. The statistical community of the study is subjected to people with mild cognitive impairment which has been evaluated with early physician diagnosis and psychologist assessment with MMSE test and Vexler memory. At first, the subjects were evaluated with computer software NBack1 and N-back2 to evaluate their working memory. Based on this process people with this disorder were sifted and divided randomly in two groups of experimental and control (each group includes 15 ones). Then, the experimental group received 12 sessions’ interventions, two hours in 12 weeks. To study these interventions, the whole subjects were retested with N-Back1 and N-Back2 programs after ending 12 sessions. In order to analysis the data, MANCOVA covariance analysis statistical test was applied; the results representing the increased mean of experimental working memory scores in compare to control group; hence, it can be concluded that the rehabilitation of cognitive issues can lead to the recovery of working memory function. (F=12.12; sig>0.01). (F=11.91; sig>0.01). The cognitive rehabilitation has an impact on the recovery of people with mild cognitive impairment.
