Deep brain stimulation triggered by a patient-specific neural biomarker of a high-symptom state may better control symptoms of major depressive disorder compared to continuous, open-loop stimulation. This protocol provides a workflow for identifying a patient-specific neural biomarker and controlling the delivery of therapeutic stimulation based on the identified biomarker.
We are assessing the therapeutic benefit of closed-loop personalized deep brain stimulation for the treatment of major depressive disorder. This protocol outlines how to identify a personalized neural biomarker that is correlated with symptom severity, and then program an implanted neurostimulator to administer stimulation using that biomarker. Prior applications of deep brain stimulation for depression used continuous stimulation, which was always on, regardless of symptom status.
This protocol describes using closed-loop stimulation in which we only deliver stimulation during high symptom states. Continued work to identify biomarkers for control of closed-loop stimulation will facilitate an approach where we can target the unique time courses of different symptoms.

本研究评估了闭环个性化深部脑刺激(DBS)对重度抑郁症(MDD)的治疗效果。提供了一种工作流程,用于识别与症状严重程度相关的个体化神经生物标志物,从而实现针对个体的刺激调控,以替代传统的持续刺激方法。
针对重度抑郁症(MDD)的闭环神经刺激技术引入了一种由生物标志物驱动的新范式,能够实现基于个体患者的实时干预。该方法应对了症状变异性及治疗适应性的挑战,在神经科学与个体化医学的交汇点上提供了可预测的信心。通过将刺激递送与高症状状态同步,该工作流程支持在神经精神类器械开发中进行风险调整的推进和产品差异化。
这种闭环神经刺激工作流程将重度抑郁症的早期发现、生物标志物验证和转化设备编程连接在一起。
