In comparative analyses, the prevalence of MS continues to lead, while the rates of NMOSD and MOGAD have gained attention as diagnostic techniques have advanced, revealing a wider spectrum of neurological conditions previously overshadowed by MS.

Recent data reflects a prevalence rate of MS in South Korea ranging between approximately 5.7 to 15.4 cases per 100,000 persons. This rising trend appears to align with global reports indicating an uptick in MS cases due to factors such as environmental changes, improved awareness, and refined diagnostic practices (Lee et al., 2021). Notably, the female-to-male ratio in MS prevalence persists at around 3:1, echoing global patterns and suggesting underlying biological or socio-environmental influences that predispose women to develop the disease at a higher rate.

Conversely, NMOSD, until recently often misclassified as MS, has shown prevalence rates estimated between 0.5 to 4.0 per 100,000. The evolution in understanding NMOSD has led to enhanced diagnostic criteria and increased recognition of its clinical features, which has contributed to a better understanding of its actual occurrence within the population. Similarly, MOGAD, which is emerging as a distinct clinical entity, presents a prevalence that ranges from 0.1 to 1.0 per 100,000. The emergence of targeted antibodies associated with MOGAD has facilitated diagnoses that previously might have been missed, showcasing the importance of specialized testing in accurate disease identification (Wang et al., 2020).

Geographic analysis within South Korea reveals disparities in the prevalence of these conditions.
