Purpose: This study evaluates the grey and white brain matter characteristics in women with multiple sclerosis (MS) and de trusor sphincter dyssynergia (DSD). Grey matter is assessed via the functional connectivity (FC) of brain regions activated during voiding, using functional magnetic resonance imaging (fMRI). Two white matter tracts involved in bladder function, the anterior thalamic radiation (ATR) and superior longitudinal fasciculus (SLF), were evaluated using diffusion tensor imag ing.
Methods: Twenty-seven women with MS (2 groups: no-DSD [n=23] or DSD [n=4]), and 8 healthy controls (HCs) under went concurrent urodynamic-fMRI evaluation with 4 cycles of bladder filling and emptying. A FC similarity measure (FC_ sim) was calculated for each subject to express the similarity of individual FC at voiding initiation compared to all FC patterns.
ATR and SLF tracts were traced and their fractional anisotropy (FA) and mean diffusivity (MD) were recorded.
Results: Mean FC_sim values were significantly different among the 3 groups indicating distinct FC patterns; however, no sig nificant difference was found between DSD and no-DSD groups. DSD group showed trends of lower FA and higher MD? indicating loss of coherence?in all tracts compared to HCs, and in the left and right ATR when compared to MS women with neither DSD nor voiding dysfunction (VD), suggesting more damage in these tracts for MS women with DSD.
Conclusions: Women with MS show distinctly different FC patterns compared to HCs. There are trends showing more dam age in the ATR in women with MS and DSD compared to those with neither DSD nor VD.
