  ABSTRACT: Objectives: To study the prevalence of vitamin D deficiency among newly diagnosed multiple sclerosis patients. Patients and Methods: It is a case control cross matching age related study done on totally 40 subjects (20 patients are newly diagnosed as MS; patients don’t start any medication for MS (naive patients) and 20 subjects are controls with the same age and sex). Base line vitamin D level was measured (i.e. vitamin D, 25-OH (total)) and MRI brain with contrast was done for all patients. Results: Low total vitamin D level was seen among 65% of patients with MS (13/20); however, this was only 20% of normal controls (4/20). Conclusion: Hypovitaminosis D is common in MS patients.
