Abstract
In patients with Paraneoplastic Neurological Disorders, the researcher detected several autoanti‐bodies reacting with neuronal antigens and tumors; their characteristics supported the hypothesis that autoimmunity plays a part in these diseases and gave impetus to the study of these neurological disorders. The relationship between detection of anti‐neuronal antibodies, clinical syndromes, and certain types of tumors suggested the utility of these antibodies as a new tool for clinical diagnosis, although their function in the pathogenesis of the various syndromes is still unclear. This paper intends to review the characteristics of the anti‐neuronal antibodies so far identified, their correlation with clinical syndromes, and the function of antigens. In addition, the paper will offer some insights on the immunological mechanisms of neuronal damage and on treatment options.
