The current research aims to investigate the impact of cognitive rehabilitation on the memory improvement of Alzheimer disease patients.<br> <strong>Methods</strong>: This was a semi-experimental design with pre-test and post-test designs. The statistical population in Baghdad City, Iraq, in 2021 included 60 patients with Alzheimer and was divided into an experimental (n=30) and a control group (n=30). The patient&rsquo;s cognitive abilities were assessed before the intervention (pre-test), promptly after the intervention (post-test), and 2 months later (follow-up). The experimental group had twenty-eight 45-min sessions of training based on the Montessori method (2 sessions per week). The data were analyzed via the SPSS software, version 19, using the independent t-test and repeated measures analysis of variance. The results had a P<0.05.<br> <strong>Results</strong>: The findings of the independent t-test demonstrated no significant difference between the scores of both groups during the pre-test stage (P>0.05); however, the difference was significant during the post-test and follow-up stages (P<0.001). In addition, the findings of the repeated measure analysis of variance indicated a significant difference between both groups&rsquo; mean scores in the post-test and follow-up (P<0.001).<br> <strong>Discussion</strong>: Cognitive rehabilitation can help patients with memory disorders and positively affect their memory performance.<br> <br> <strong>Coresponding author:</strong>&nbsp;Ali Abdulhussain Fadhi,&nbsp;E-mail:&nbsp;alialshamary412@yahoo.com</span></span></span><br> &nbsp;</div> Alzheimer, Cognitive rehabilitation, Memory improvement 319 326 http://irj.uswr.ac.ir/browse.php?a_code=A-10-2066-1&slc_lang=en&sid=1 Ali Abdulhussain Fadhi alialshamary412@yahoo.com 0000-0000-0000-0000 Yes Department of Medical Laboratory Techniques, College of Medical Technology, Al-Farahidi University, Baghdad, Iraq.
