The suggestion of a possible relationship between depression and multiple sclerosis (MS) has existed for many years, and the prevalence studies are believed by potential biases. In our country, the prevalence of clinical depression in patients with MS is unknown. The objective of the present study was to ascertain the rate of depression in a group of MS patients and to analyze the relationship to depression, disability, gender, age and duration of illness. We evaluated 84 relapsing-remitting MS patients using the Beck Scale (BS), the Hospital Anxiety and Depression scale (HAD) and the Expanded Disability Status Scale (EDSS). The depression was presented at 17.9% and the anxiety at 34.5% of the RRMS patients. There is a correlation between depression and functional disability (p=0.0002), but there is no relation between depression and sex, age or duration of the illness. This analysis confirms that depression is common in persons with MS and suggests the association with functional disability.
