A new research published in Neurology focuses on the global challenges to early detection and diagnosis of multiple sclerosis (MS). Despite substantial resources and registries, diagnostic delays are severe. The study indicated that 36 nations solely utilize the 2017 McDonald criteria (McD-C) for MS diagnosis, based on data from the Multiple Sclerosis International Federation (MSIF) survey. Patients’ lack of understanding of MS symptoms, as well as a paucity of skilled healthcare providers, have been identified as hurdles to early diagnosis, particularly in low-income countries. A lack of understanding or training among neurologists was noted as a hindrance to adopting the 2017 McD-C. Less than half of the nations examined had created national standards for MS diagnosis, with higher-income countries more likely to do so.
