abstract = {AbstractBackground Stimulation-induced dysarthria (SID) is
a troublesome and potentially therapy-limiting side effect
of deep brain stimulation of the subthalamic nucleus
(STN-DBS) in patients with Parkinson’s disease (PD). To
date, the origin of SID, and especially whether there is an
involvement of cerebellar pathways as well as the pyramidal
tract, remains a matter of debate. Therefore, this study
aims to shed light on structural networks associated with
SID and to derive a data-driven model to predict SID in
patients with PD and STN-DBS.Methods Randomised,
double-blinded monopolar reviews determining SID thresholds
were conducted in 25 patients with PD and STN-DBS. A
fibre-based mapping approach, implementing the calculation
of fibr-wise ORs for SID, was employed to identify the
distributional pattern of SID in the STN’s vicinity. The
ability of the data-driven model to classify stimulation
volumes as ‘causing SID’ or ‘not causing SID’ was
validated by calculating receiver operating characteristics
(ROC) in an independent out-of-sample cohort comprising 14
patients with PD and STN-DBS.Results Local fibre-based
stimulation maps showed an involvement of fibres running
lateral and posteromedial to the STN in the pathogenesis of
SID, independent of the investigated hemisphere. ROC
analysis in the independent out-of-sample cohort resulted in
a good fit of the data-driven model for both hemispheres
(area under the curve (AUC)left=0.88,
AUCright=0.88).Conclusions This study reveals an involvement
of both, cerebello-thalamic fibres, as well as the pyramidal
tract, in the pathogenesis of SID in STN-DBS. The results
may impact future postoperative programming strategies to
avoid SID in patients with PD and STN-DBS},
