All patients underwent detailed history and examinations and were followed at 3 monthly intervals. They were evaluated using standard investigations including gadolinium-enhanced magnetic resonance imaging (MRI) of the brain and spine with thin section optic nerve cuts and treated as per the standard guidelines. Data were recorded meticulously.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The mean age was 33.7 \u00b1 13.4 years. The mean age at disease onset was 31.2 \u00b1 13.5 years. Female-to-male ratio was 1.9:1. About 32.1% of patients presented with optic neuritis (ON), 56.8% with transverse myelitis (TM), and 11.1% with both ON and TM. The mean time from disease onset to diagnosis was 16.17 \u00b1 23.09 months. Muscle atrophy, Lhermitte symptom, and tonic spasms were common. Foster\u2013Kennedy syndrome-like presentation was seen in 8.6%. NMO antibodies were positive in 41 patients. MRI revealed involvement of &lt;4 vertebral segments in 16.4% of patients with TM. Patients were managed as per standard guidelines. The mean follow-up duration was 15.3 \u00b1 6 months. Approximately 88.9% had good functional outcome.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>NMOSDs are a common cause of demyelinating illnesses in Northern India.
