Optimizing Stimulation Parameters for Electroconvulsive Therapy (PRESTO)
Parameter Refinement for ECT Stimulation and Titration Optimization
The goal of this clinical trial is to improve how electroconvulsive therapy (ECT) stimulation settings are chosen. Researchers will use real-time brain monitoring to measure both seizures and a recently identified brain event called cortical spreading depolarization (CSD).
The main questions it aims to answer are:
What is the best way to increase ECT stimulation settings? How do different pulse settings affect the brain's response? Can certain settings produce CSD without causing a seizure?
Participants already receiving ECT as part of their care will take part. They will be assigned to one of two groups:
Index ECT group: Participants starting ECT will receive different standard titration approaches.
Maintenance ECT group: Participants receiving ongoing ECT will undergo a brief, low-dose stimulation test before treatment.
All participants will be monitored using brain physiology (EEG and blood flow) and symptom scales during treatment.

Подробное описание
This is an exploratory, single-center open-label clinical trial at Pennsylvania Hospital (PAH) intended to optimize stimulation settings for electroconvulsive therapy (ECT), guided by real-time monitoring of both seizure and a recently discovered postictal event: cortical spreading depolarization (CSD). We will address three key questions: 1. What is the best strategy for up-titrating settings for ECT?; 2. How do individual pulse parameters impact brain evoked response?; 3. Are there stimulation settings that directly induce CSD waves without seizure?
This study will take place in the context of routine treatments for patients already consenting to receive ECT for a wide range of clinical indications. Patients will be enrolled in one of two arms:
- Index Titration Arm: Patients coming in for initial index ECT courses (acute phase) will be randomized to one of several stimulation parameter titration tables while receiving otherwise routine ECT care.
- Maintenance Arm: In clinically stable patients receiving monthly maintenance ECT, a sub-convulsive stimulation settings ramp will be performed under anesthesia immediately preceding their regular ECT treatment.
All patients being treated with ECT at PAH are eligible for this study. Outcomes will include non-invasive monitoring of brain hemodynamics and EEG as well as clinical symptom scales.
