Objectives: Multiple Sclerosis has explored a variety of mental and physical disabilities and setbacks which are difficult to explain precisely. Moreover, their classification is another uphill task to identify them in the category. Additionally, clinical scholars found it difficult to explore the factors which lead to the outcomes of the neuro-rehabilitation cycle. By considering the intricacy in terms of Multiple Sclerosis and RP, this research endeavoured to examine the mental infirmities among relapsing-remitting multiple sclerosis patients (RRMS). Methodology: We took two sets of patients and each carried twenty-seven patients and examined their intellectual performances. Those groups are termed as RRMS and HC (Healthy Controlled) subsequently. In terms of this clinical examination, every patient observed a thorough study of their cognitive state including physical and mental disabilities. These clinical evaluations based on Stroop tests, and WMSR tests. This research was completed at Services Hospital, Lahore (February to November 2017). Results: The statistical values portrayed a clear difference among all the constituents of groups as the p-value of Stroop test is (<0.05), WMS-Digit Span has the p-value (<0.05), p-value (<0.001) in WMS-Logical Memory and the value of p is (<0.001) for WMS-Visual Reproduction. The significance remained while the depression's effect was controlled. We observed a similar difference between delayed and immediate visual reproduction among the RRMS subjects as the value of p is (<0.05) for WMSVRI and WMSVRD. So, on the grounds of the findings of this research, we can make the case that the ratio of mental disorders and deficiencies are more common among RRMS cases. Conclusion: Research scholars and discipline related physicians must take up this case of mental evaluation and restoration of the subjects in connection with the other disciplines too, especially for the cases of RRMS.
