Primary Outcome Measures
NameTimeMethod
<p>The main endpoint in this study is the response to STN DBS as measured by an<br /><br>acute stimulation challenge performed 12 months after surgery, defined as the<br /><br>percentage change of MDS-UPDRS motor score after overnight medication<br /><br>withdrawal between *off*-stimulation and *on*-stimulation. We will compare the<br /><br>accuracy of the three models (described under Objectives) in predicting this<br /><br>primary endpoint. In all models the effect of pertinent covariates and<br /><br>variability between centres will be taken into account. </p><br>
Secondary Outcome Measures
NameTimeMethod
<p>- the occurrence of psychotic symptoms in the 72 hours following surgery, as<br /><br>measured by a score >=3 on the delirium observation scale (DOS).<br /><br>- the change in quality of life after surgery, the *Global satisfaction with<br /><br>surgery* scale and the number of contacts (outpatient visits, telephone calls,<br /><br>emails) with the hospital team (neurologists, parkinson nurses) in the first<br /><br>year.<br /><br>- the SENS-PD score and MDS-UPDRS motor score.<br /><br>- the cognitive decline 12 months after surgery, as defined by either a) the<br /><br>transition to mild cognitive impairment or PD-related dementia diagnosed<br /><br>according to criteria proposed by the Movement Disorders Society, or b) a<br /><br>reduction in MoCA score >3 points.</p><br>
