BACKGROUND Although dementia is a contraindication for deep brain stimulation (DBS) in patients with Parkinson's disease (PD), the concept is supported by little scientific evidence. Moreover, it is unclear whether PD with mild cognitive impairment (PD-MCI) or domain-specific cognitive impairments affect the outcome of DBS in non-demented PD patients. OBJECTIVE To investigate the influence of baseline cognitive profiles of PD on the outcome of DBS. METHODS Baseline cognitive levels of patients with PD who underwent DBS were classified into PD with dementia (PDD) (n = 15), PD-MCI (n = 210), and normal cognition (PD-NC) (n = 79). The impact of the cognitive level on key DBS outcome measures [mortality, nursing home admission, progression to Hoehn&Yahr (HY) stage 5 and progression to PDD] were analyzed using Cox regression models. We also investigated whether impairment of a specific cognitive domain could predict these outcomes in non-demented patients. RESULTS Patients with PDD showed a substantially higher risk of nursing home admission and progression to HY stage 5 compared with patients with PD-MCI [hazard ratio (HR) 4.20, P = .002; HR = 5.29, P < .001] and PD-NC (HR 7.50, P < .001; HR = 7.93, P < .001). MCI did not alter the prognosis in patients without dementia, but those with visuospatial impairment showed poorer outcomes for nursing home admission (P = .015), progression to HY stage 5 (P = .027) and PDD (P = .006). CONCLUSIONS Cognitive profiles may stratify the pre-operative risk and predict long-term outcomes of DBS in PD.

认知特征作为帕金森病脑深部刺激后长期结果的预测指标

背景虽然痴呆症是帕金森病 (PD) 患者深部脑刺激 (DBS) 的禁忌症,但这一概念几乎没有得到科学证据的支持。此外,尚不清楚伴有轻度认知障碍 (PD-MCI) 或领域特异性认知障碍的 PD 是否会影响非痴呆 PD 患者 DBS 的结果。目的 研究 PD 的基线认知特征对 DBS 结果的影响。方法 将接受 DBS 的 PD 患者的基线认知水平分为 PD 痴呆(PDD)(n = 15)、PD-MCI(n = 210)和正常认知(PD-NC)(n = 79)。使用 Cox 回归模型分析了认知水平对 DBS 关键结局指标 [死亡率、疗养院入住率、进展到 Hoehn&Yahr (HY) 5 期和进展到 PDD] 的影响。我们还调查了特定认知领域的损害是否可以预测非痴呆患者的这些结果。结果 与 PD-MCI 患者相比,PDD 患者进入疗养院和进展到 HY 5 期的风险显着更高 [风险比 (HR) 4.20,P = .002;HR = 5.29,P < .001] 和 PD-NC(HR 7.50,P < .001;HR = 7.93,P < .001)。MCI 并未改变无痴呆患者的预后,但有视觉空间障碍的患者在入住疗养院 (P = .015)、进展至 HY 5 期 (P = .027) 和 PDD (P = .006) 方面的预后较差。结论 认知特征可以对术前风险进行分层并预测 DBS 在 PD 中的长期结果。结果 与 PD-MCI 患者相比,PDD 患者进入疗养院和进展到 HY 5 期的风险显着更高 [风险比 (HR) 4.20,P = .002;HR = 5.29,P < .001] 和 PD-NC(HR 7.50,P < .001;HR = 7.93,P < .001)。MCI 并未改变无痴呆患者的预后,但有视觉空间障碍的患者在入住疗养院 (P = .015)、进展至 HY 5 期 (P = .027) 和 PDD (P = .006) 方面的预后较差。结论 认知特征可以对术前风险进行分层并预测 DBS 在 PD 中的长期结果。结果 与 PD-MCI 患者相比,PDD 患者进入疗养院和进展到 HY 5 期的风险显着更高 [风险比 (HR) 4.20,P = .002;HR = 5.29,P < .001] 和 PD-NC(HR 7.50,P < .001;HR = 7.93,P < .001)。MCI 并未改变无痴呆患者的预后,但有视觉空间障碍的患者在入住疗养院 (P = .015)、进展至 HY 5 期 (P = .027) 和 PDD (P = .006) 方面的预后较差。结论 认知特征可以对术前风险进行分层并预测 DBS 在 PD 中的长期结果。MCI 并未改变无痴呆患者的预后,但有视觉空间障碍的患者在入住疗养院 (P = .015)、进展至 HY 5 期 (P = .027) 和 PDD (P = .006) 方面的预后较差。结论 认知特征可以对术前风险进行分层并预测 DBS 在 PD 中的长期结果。MCI 并未改变无痴呆患者的预后,但有视觉空间障碍的患者在入住疗养院 (P = .015)、进展至 HY 5 期 (P = .027) 和 PDD (P = .006) 方面的预后较差。结论 认知特征可以对术前风险进行分层并预测 DBS 在 PD 中的长期结果。
