Objective: Multiple sclerosis (MS) is an inflammatory and demyelinating disease of the central nervous system of a chronic nature, most often with periods of exacerbation and remission, mainly affecting people between 20-40 years of age, with a slight prevalence of women. The aim of the study was to collect and analyze materials published in the literature regarding the prevalence and co-occurrence of mental disorders in patients with multiple sclerosis. Current reports show that as many as 75% of patients with this chronic disease experience various mental disorders, and the incidence of mental diseases - including mood disorders and anxiety disorders - is statistically higher than in the general population.
Conclusion: Conclusions: Depending on the literature, depressive symptoms appear in 6.94% -70.1% of patients with MS. Diagnosis of anxiety disorders affects 11.1% of patients, while bipolar disorder affects up to 16.2%. Co-occurrence of MS with schizophrenia is estimated at 1.28%. The incidence of other psychoses is 2-4% in patients with MS. Only in the case of schizophrenia, men with MS are more likely to develop it, while other psychiatric disorders are more common among women. Co-occurrence of mental disorders in the course of multiple sclerosis adversely affects the treatment process and the functioning of patients and their families.
