Background:
Multiple sclerosis (MS) can involve cognitive entities, including memory, attention, performance, and information processing. Furthermore, MS causes depression and negatively affects the quality of life (QOL). This study was aimed to assess the efficacy of cognitive rehabilitation on cognitive entities of MS patients.
Materials And Methods:
This is a clinical trial study conducted on 56 MS patients in 2016-2017. Patients were randomly divided into two Groups of A (cognitive rehabilitation) and B (control group). Patients were evaluated in terms of memory, attention, QOL, and depression. Questionnaires included Abbreviated Mental Test, Prospective and Retrospective Memory Questionnaire, Everyday Memory Questionnaire, Digit Spam test for attention assessment, QOL-54 questionnaire, and Second version of Beck questionnaire assessing depression. They were filled through an interview before the study initiation, and then, the intervention group underwent ten sessions of cognitive rehabilitation and questionnaires refilled within 3 months after study initiation. Outcomes of the two groups were compared.
Results:
Memory, attention, QOL, and depression improved significantly following the intervention in cases (P < 0.05), while no significant change was observed among controls (P > 0.05). Comparison of cases and controls in the second evaluation showed a significant difference between cases and controls (P < 0.05).
Conclusion:
Ten sessions of cognitive rehabilitation could significantly improve MS patients' cognitive performance. Moreover, this approach affected their QOL and sense of depression in a decisive trend. It can be concluded that cognitive rehabilitation can successfully affect numerous aspects of MS patients, while numerous medical therapies may be required for treatment of each mere aspect. Further evaluations are strongly recommended.
