Abstract :Objective: In this study, we aimed to investigate whether serum homocysteine level was higher in patients with MS, and evaluate the effect of this situation on cognitive functions. In addition, we aimed to determine whether high blood homocysteine level is associated with socio-demographic and clinical features and determine the affected cognitive functions with neuropsychological tests. Methods: We looked at changes in the levels of vitamin B12 and folic acid associated with high levels of serum homocysteine levels. Cognitive performance, and laboratory values of 60 cases with Relapsing-remitting MS insert ignore into journalissuearticles values(RRMS); patient, and 30 healthy volunteers were compared. The frontal lobe activities, information processing speed, flexibility, and the ability of the calculation, as well as cognitive functions of attention and visuospatial perception and construction of complex skills were also evaluated. For these purposes, Paced Auditory Serial Addition Test insert ignore into journalissuearticles values(PASAT);, Line Orientation Test insert ignore into journalissuearticles values(LOT); and Stroop Test were used. Results: Test performance for all of the test steps were found to be defective in MS group more than the control group subjects. In addition, all steps of the test performance were found to be impaired in both patients and healthy subjects with high levels of homocysteineinsert ignore into journalissuearticles values(p<0.001);. Conclusion: In this study visual memory processes, visual-spatial functions, construction skills, planning, programming and executive functions were found to be significantly deteriorated and the reaction time prolonged in RRMS patients with high levels of homocysteine compared with healthy control group
