Study Summary

This study is focused on advancing ECT treatment for older adults with depressive disorders by refining neuromodulation stimulus parameters to improve efficacy and cognitive safety.

Primary Outcome

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 milliamp
