Introduction: Age-related cognitive decline or cognitive aging is largely the result of structural and functional decline in specific areas of the brain, but lifestyle also contributes to this cognitive decline. The aim of this study was to investigate the effect of working memory rehabilitation on visual memory and memory span in ageing.
 Methods: This was a quasi-experimental study with pretest-posttest design and a control group. The study population included all elderly people who lived in Bukan Nursing Home from April to July 2019 (N = 120). Among these individuals, 30 elderly people were selected by convenience sampling method and then randomly assigned to two experimental and control groups (two groups of 15 people). Kim Karad Visual Memory Test and Wechsler Memory Span Test were taken from the groups in pretest. The working memory rehabilitation was performed in 18 sessions (each sessions 60-minute) and after which the test was performed again. The data were analyzed by multivariate covariance test according to its assumptions.
 Results: The results showed that after the rehabilitation of working memory, in the experimental group, the mean of short, medium and long components of visual memory were 12.00, 10.8 and 12.33, respectively, and the direct and inverse of memory span were 11.66 and 9.66, respectively. In the control group, the average of short, medium and long components of visual memory is 7.00, 6.70 and 9.00, respectively, and direct and inverse of memory span is 8.33 and 6.46, respectively. The difference in the mean scores between the two groups in the components of visual memory and memory span after the intervention was significant (p < 0.001).
Conclusion: The results showed that working memory rehabilitation can improve visual memory and memory span, and it is recommended that this rehabilitation method be used to improve the cognitive functions of the elderly.
