Methods In a cross-sectional study of 365 multiple sclerosis patients selected through a random sampling method from the MS society of Riyadh, Saudi Arabia, we collected data by self-administered questionnaires - the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder (GAD-7) questionnaire - and analyzed by descriptive and analytical statistics. Results Approximately 51.1% of participants had moderate or severe anxiety and 64% of them had depression among community-based multiple sclerosis patients according to Generalized Anxiety Disorder (GAD-7) questionnaire, and according to the PHQ-9 Arabic version about 28.85% showed mild to moderate depression. The MS patients aged 53 to over 60 years showed higher levels of mild anxiety (76.32%) and higher levels of depression ranging from mild to moderate (53.61%) (P = 0.001). While the MS patients younger than 53 years showed moderate to severe anxiety (60.71%) and depression levels (62.32%). In different age group bad health status (37.6%) was associated with a higher prevalence of depression levels (P =< 0.001) and people who were widowed (22.38%), divorced (26%), and separated (37.82%) had significant depression levels (P = 0.017). In terms of anxiety, 54.58% of females had anxiety (P = 0.005), more older people showed anxiety (43.17%) (P = 0.026), and people with a bad general health state (26.38%) had anxiety (P = <0.001). Conclusion Among different types of MS patients, anxiety is more prevalent in the elder group (76%) of people and depression is more prevalent in young patients (62%).
