Ultrasonographic Evaluation of Cerebral Arterial and Venous Haemodynamics in Multiple Sclerosis: A Case-Control Study (full paper) http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4216015/

Conclusion: " In conclusion, our study suggested that the quantitative evaluation of CBF and CVF and their postural dependency may be related to a dysfunction of autonomic nervous system that seems to characterize more disabled MS patients. It's not clear whether the altered postural control of arterial inflow and venous outflow is a specific MS condition or simply represents an “epiphenomenon” of neurodegenerative events. Further studies correlating ultrasonographic hemodynamic data with MR imaging lesion load and with perfusional parameters are needed in order to confirm our hypothesis."
