Background: These are two diseases of the central nervous system which are associated with demyelization of nerves and which has caused neurological disease and disability all over the world. Multiple Sclerosis (MS) and Neuromyelitis Optica (NMO) are chronic diseases exhibiting features of an autoimmune affection mainly affecting the central nervous system. To date, no study or report has looked at the epidemiology and clinical profile of these disorders in Middle Eastern countries, Iraq included, even though there is bibliographic evidence of the existence of these conditions in Western peoples. This project aims at encompassing this gap by carrying out a descriptive epidemiological analysis study of multiple sclerosis (MS)and neuromyelitis optica (NMO) in the Iraqi population. In this case, the research is going to be aimed at the demographic characteristics of patients, their clinical presentation and outcomes of their treatment. Methodology: A post hoc comparative cross-sectional examination of the medical records of 600 patients in Iraq was performed as part of the present investigation. For this study, data was gathered and analyzed. An additional 150 individuals with neuromyelitis optica and 450 patients with multiple sclerosis were recalled from the sample. The information was collected from Baghdad Teaching hospital in Medical City complex. The records of the patients were combed through for the previous 10 years in a row in order to determine the demographic and clinical features of the patients, as well as information on the relapses, treatment, and rehabilitation processes. In order to examine the prevalence and incidence of the two illnesses, the research used comparisons based on frequency and percentage analysis, as well as the t-test and the Chi square statistic. Results Although there were some similarities between NMO and MS, the relapse rate was notably higher in NMO patients (3. 4, compared with 2. 8 in patients with MS), and severe relapses were more frequent in the NMO group (38. ∗%, compared with 29. ∗% in the MS group; p = 0. 041). This means that NMO is much more aggressive than MS. Moreover, the NMO patients experienced more severe and longer lasting relapses than the Ms patients (median relapse duration 4. 1 weeks, p = 0. 008 compared to the 3. 2 weeks of Ms patients; 34. 7% degree of impairment in NMO patients, p = 0. 007 compared to the 21. 8% degree of impairment in Ms patients). The first notitur is that more patients with NMO received immunosuppressants (86. 7% versus 46. 7% of patients with multiple sclerosis who received immunosuppressive drugs; p = 0. 001) Thus, it is necessary to use other approaches with this group of patients. Despite this, the results showed that there was no significant difference between the two groups in relation to the time it took to resume work and/or a normal lifestyle. Thus, out of the sample, 28% showed complete recovery with the remainder 56%. Regarding the recoveries made, majority stated they had full recovery at 92 percent, 8 percent had partial recovery. Conclusion: The current study focuses on this problem in the Iraqi population and also acknowledge that NMO seems to be worse and more progressive than MS. It also puts much stress on the early diagnose of such cases as well as the use of treatment techniques that are both wide and intense especially with those who have other related complications of NMO. Each of the result supports the argument of the need to establish new treatment procedures that are relative to the area with the intention of enhancing the living standards of the patients. These results are a significant addendum to the overall shortage of knowledge of multiple sclerosis and neuromuscular disorder in the regarding of patients who belong to the developing world. In addition, they form a basis for future research that will help in the discovery of methods that can be utilised in enhancing disease treatment in the developing countries.
