Assessment of autonomic nervous system dysfunction in multiple sclerosis and association with clinical disability
نویسندگان
چکیده
Recent studies have reported autonomic dysfunction (AD) in multiple sclerosis (MS), and bladder and/or bowel dysfunction, orthostatic hypotension, and cardiac adaptation disorders have been observed in a wide range of patients (15-80%). The primary aim of this study is to investigate the frequency and association of AD in MS patients, assessed by sympathetic skin response (SSR) and a symptoms questionnaire. The secondary aims are to study the association of AD and disease disability assessed by expanded disability status scale (EDSS), as well as disease duration. One hundred clinically definite MS (CDMS) patients were evaluated for autonomic nervous system (ANS) dysfunction by use of an autonomic symptoms questionnaire and SSR testing. The relationship between these methods, AD and disease-related parameters, such as the expanded disability status scale (EDSS) and disease duration were all evaluated. Sixty-five per cent of the patients presented with AD and 29% of these patients had abnormal SSR results. MS patients with high EDSS values (EDSS>4) and longer disease duration were more likely to have ANS dysfunction (p<0.0001). ANS dysfunction is not uncommon in CDMS patients and thus non-invasive investigations of AD are warranted to optimize AD evaluation and disease management.
