Autonomic dysfunction in multiple sclerosis

Results: Autonomic symptoms were significantly more prevalent in MS patients than in the controls. Cardiovascular, urinary and gastrointestinal symptoms were highly prevalent. The severity of the different autonomic symptoms as assessed by ANSDS, were higher in the patients than the controls. All 5 Ewing tests in the patients showed highly significant abnormal results as compared to those of the control. Definite parasympathetic derangement was found in 45.5% of the patients while combined sympathetic and parasympathetic derangements were found in 34.5% of the patients. There were significant correlations between the finding of definite autonomic dysfunctions and the age of the patients at the time of assessment and the duration of the disease. Conclusions: Autonomic dysfunctions as assessed by a formal interview, ANSDS and by Ewing tests were common in Iraqi MS patients. Careful attention to autonomic disturbances should be considered in the routine evaluation of MS patients which might help in improving their quality of life.
