BACKGROUND: It has been suggested there is a chronic neurodegenerative disorder,
underlying the pathophysiology of multiple sclerosis (MS), which is distinct from
the more obvious immune-mediated attack on the white matter. Limited data exists
indicating there is an alteration in pulse wave propagation within the
craniospinal cavity in MS, similar to the findings in normal pressure
hydrocephalus (NPH). It is hypothesized MS may harbor pulse wave encephalopathy.
The purpose of this study is to compare blood flow and pulse wave measurements in
MS patients with a cohort of NPH patients and control subjects, to test this
hypothesis. METHODS: Twenty patients with MS underwent magnetic resonance (MR)
flow quantification techniques. Mean blood flow and stroke volume were measured
in the arterial inflow and venous out flow from the sagittal (SSS) and straight
sinus (ST). The arteriovenous delay (AVD) was defined. The results were compared
with both age-matched controls and NPH patients. RESULTS: In MS there was a 35 %
reduction in arteriovenous delay and a 5 % reduction in the percentage of the
arterial inflow returning via the sagittal sinus compared to age matched
controls. There was an alteration in pulse wave propagation, with a 26 % increase
in arterial stroke volume but 30 % reduction in SSS and ST stroke volume. The AVD
and blood flow changes were in the same direction to those of NPH patients.
CONCLUSIONS: There are blood flow and pulsation propagation changes in MS
patients which are similar to those of NPH patients. The findings would be
consistent with an underlying pulse wave encephalopathy component in MS.
