OBJECTIVE
To assess the influence of preoperative depression on the change in freezing of gait (FOG) following subthalamic nucleus stimulation (STN-DBS) in patients with Parkinson's disease (PD).
METHODS
One hundred and twelve PD patients were included who received bilateral STN-DBS. Of these, 33 had no preoperative depression (PD-ND) and the other 79 had preoperative depression (PD-D). Each PD-ND patient was matched with one PD-D patient by the propensity score for which sex, age at PD onset, disease duration, UPDRS-III score during off-medication state, levodopa-equivalent daily dose, and mini mental state examination were the independent variables. We compared both a FOG-questionnaire (FOG-Q) and the axial score from UPDRS-III between the two groups over 12-month follow-up.
RESULTS
During the off-medication state, FOG-Q at 12-month was decreased with STN-DBS in both PD-ND (-52.9%, p < 0.001) and PD-D (-24.2%, p < 0.001) with a significant difference in the change of FOG in favor of PD-ND (p = 0.001). Similarly, there was an improvement in the axial score for both PD-ND (-66.1%, p < 0.001) and PD-D (-45.3%, p < 0.001) at 12-month with a significant difference between the groups. (p = 0.005). During the on-medication state, both the FOG-Q and axial score at 12-month were not improved with STN-DBS in the PD-ND and PD-D with no difference between the groups.
CONCLUSIONS
Our findings suggest that preoperative depression negatively affects the outcome of FOG following STN-DBS in the off-medication state but not in the on-medication state.
目的
评估术前抑郁对帕金森病（PD）患者接受丘脑底核刺激（STN-DBS）后冻结步态（FOG）变化的影响。
方法
纳入 112 例接受双侧 STN-DBS 的 PD 患者，其中 33 例患者术前无抑郁（PD-ND），79 例患者术前有抑郁（PD-D）。每个 PD-ND 患者通过倾向评分与 1 例 PD-D 患者相匹配，匹配变量为性别、PD 发病年龄、病程、停服药物状态下 UPDRS-III 评分、左旋多巴等效日剂量和简易精神状态检查。我们比较了两组患者在 12 个月随访期间的 FOG 问卷（FOG-Q）和 UPDRS-III 轴评分。
结果
在停服药物状态下，STN-DBS 可降低 PD-ND（-52.9%，p<0.001）和 PD-D（-24.2%，p<0.001）患者的 FOG-Q，且 PD-ND 组的 FOG 改善程度明显优于 PD-D 组（p=0.001）。同样，在停服药物状态下，PD-ND（-66.1%，p<0.001）和 PD-D（-45.3%，p<0.001）患者的 UPDRS-III 轴评分在 12 个月时均有所改善，且两组之间存在显著差异（p=0.005）。在服用药物状态下，PD-ND 和 PD-D 患者的 FOG-Q 和 UPDRS-III 轴评分在 12 个月时均未改善，两组之间无差异。
结论
我们的研究结果表明，术前抑郁会影响 STN-DBS 治疗后患者在停服药物状态下的 FOG 结局，但不会影响在服用药物状态下的 FOG 结局。
