Outcome Measures

Primary Outcomes (1)

  • Beta Coefficient From Linear Regression of Amplitude-determined Seizure (Independent Variable) and Ebrain (Dependent Variable)

    Electric field modeling is used to calculate Ebrain from the pre-ECT structural MRI. Ebrain is an individual's electric field strength (Volts/meter) per unit current (milliampere). To avoid confounds from the tissue boundary effects, Ebrain is calculated as the 90th percentile of maximal. Higher values (0.2 Volts/meter per milliampere) indicate that an individual receives a higher electric field strength per unit current. The Ebrain in this sample ranges from 0.1 to 0.19 Volts/meter per milliampere. Linear regression model assessed the relationship between amplitude-determined seizure (independent variable) and Ebrain (dependent variable) with beta coefficient and 95% confidence intervals.

    First treatment

Study Arms (1)

Experimental arm

EXPERIMENTAL

All subjects enrolled will receive amplitude titration for their first treatment. The remainder of the ECT series will be completed with traditional (800mA) pulse amplitude with right unilateral electrode placement. This investigation only includes the single open-label arm.

Device: Mecta Spectrum 5000Q paired with Soterix Medical 4X1 HD - ECT Multi-Channel Stimulation Interface

Interventions

The Mecta Spectrum 5000Q paired with Soterix Medical 4X1 HD-ECT Multi-Channel Stimulation Interface will reduce ECT current amplitude for amplitude-seizure titration.
