A cross-sectional exploratory study was conducted involving 31 male patients with approved relapsing\u2013remitting MS (RRMS), divided into smokers (\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    = 9) and non-smokers (\n                    <jats:italic toggle=\"yes\">n<\/jats:italic>\n                    = 22). The Symbol Digit Modalities Test (SDMT) and Paced Auditory Serial Addition Test (PASAT) were used to assess cognitive performance. Hand dexterity was evaluated using the 9-Hole Peg Test (9HPT). Depressive symptoms and disability were assessed via the Beck Depression Inventory (BDI) and the Expanded Disability Status Scale (EDSS), respectively. Fatigue and related factors were assessed using the Comprehensive Fatigue Assessment Battery for Multiple Sclerosis (CFAB-MS). Serum markers of oxidative stress and antioxidant status, including superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), total antioxidant capacity (TAC), malondialdehyde (MDA), and glutathione (GSH), were also measured. Smokers demonstrated significantly lower SDMT scores compared with non-smokers (36.86 \u00b1 11.16 vs. 52.47 \u00b1 18.54;\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    = .04), which was no longer significant after adjusting for EDSS and age. No significant differences were observed between groups in PASAT, 9HPT, EDSS, or BDI. Smokers reported higher anxiety and worry scores on the CFAB-MS (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    &lt; .05), while other fatigue-related domains were comparable between groups. Regarding the oxidative stress markers, a statistically significant difference was only detected in SOD activity. Regular cigarette smoking may be associated with decreased cognitive processing speed and increased anxiety in male patients with RRMS, which warrants further investigation.\n                  <\/jats:p>","DOI":"10.1177\/15579883261453962","type":"journal-article","created":{"date-parts":[[2026,5,31]],"date-time":"2026-05-31T04:00:02Z","timestamp":1780200002000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["An Exploratory Cross-Sectional Study of the Association Between Regular Cigarette Smoking and Level of Disability, Hand Dexterity, Cognitive Impairment, Fatigue, and Markers of Oxidative Stress in Male Patients With Relapsing-Remitting Multiple Sclerosis"],"prefix":"10.1177","volume":"20","author":[{"given":"Melika","family":"Ahmadi Bonabi","sequence":"first","affiliation":[{"name":"Student Research Committee, Tabriz University of Medical Sciences, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3353-1102","authenticated-orcid":false,"given":"Reza","family":"Mosaddeghi-Heris","sequence":"additional","affiliation":[{"name":"Research Center for Integrative Medicine in Aging, Aging Research Institute, Tabriz University of Medical Sciences, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niloofar","family":"Taheri","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, Stanford University, Palo Alto, CA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahnaz","family":"Talebi","sequence":"additional","affiliation":[{"name":"Neurosciences Research Center (NSRC), Tabriz University of Medical Sciences, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9723-0109","authenticated-orcid":false,"given":"Amirreza","family":"Naseri","sequence":"additional","affiliation":[{"name":"Student Research Committee, Tabriz University of Medical Sciences, Iran"},{"name":"Research Center for Integrative Medicine in Aging, Aging Research Institute, Tabriz University of Medical Sciences, Iran"},{"name":"Research Center for Evidence-Based Medicine, Iranian EBM Centre: A Joanna Briggs Institute (JBI) Center of Excellence, Tabriz University of Medical Sciences, Iran"},{"name":"Tabriz USERN Office, Universal Scientific Education and Research Network (USERN), Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,5,30]]},"reference":[{"key":"e_1_3_3_2_1","doi-asserted-by":"crossref","unstructured":"Abraham R.
