[Nervous system side effects of disease modifying treatments of rheumatoid arthritis]

Abstract

Antirheumatic medication is of crucial importance within the treatment concept of chronic inflammatory disorders. Side effects may affect various organ systems, among which are neurologic manifestations. If patients have comorbidities involving the nervous system this should be taken into consideration before choosing an individual immunosuppressant or immunomodulatory compound, as any worsening of the underlying neurologic disease should be avoided. In this article, relevant neurologic disorders will be described with respect to the clinical manifestations, differential diagnosis and treatment. In the second part, pharmaceuticals and biologicals which are frequently used as part of an antirheumatic regimen are discussed with respect to the potential to induce side effects specifically related to the nervous system.
