Shrinkage in subcortical regions of the brain was greater in patients with low baseline diastolic blood pressure in a prospective study, researchers said.
This is research in the normal population diagnosed with arterial disease, not MS, but it raises questions.
Is there a trend among people with MS to have lower blood pressure? Could this account for any of the brain atrophy seen in MS? Does treatment of CCSVI normalize blood pressure, and if it does this, is this because of improvements in the autonomic nervous system or restoration of healthy cerebral blood flow or something else? The trend of people with MS having low blood pressure is something we've discussed here, but I don't know if there is pubmed research in support of this?
