Introduction: Impaired sense of smell has a remarkable impact on quality of life. It is seen in a variety of neurodegenerative diseases such as Parkinson’s disease. In this study we assessed the olfactory function in patients with multiple sclerosis (MS) by sniff magnitude test (SMT).

Material and methods: A cross-sectional study was conducted on 48 patients with MS. A questionnaire including demographic and clinical variables was completed for each patient. The SMT was used for evaluation of olfactory function.

Results: Olfactory dysfunction was found in 14.6% of patients (8.3% hyposmia and 6.3% anosmia). Older age, longer disease duration, higher hospital admission rate, lower mini-mental status examination (MMSE) score and secondary progressive course of MS were significantly related to olfactory dysfunction.

Conclusion: Secondary progressive MS and markers of advanced disease toward neurodegenerative phase (including older age, longer disease duration and lower cognitive function) can be associated with olfactory dysfunction in MS patients.
