About this trial
A randomized controlled trial will compare hippocampal neuroplasticity, antidepressant, and cognitive outcomes between individualized amplitude and fixed 800 mA amplitude ECT in older depressed subjects (n = 25 per group, n = 50 total). Relative to fixed 800 mA ECT:
H1: Individualized amplitude arm will have improved RUL antidepressant outcome (IDS-C30 response rates and reduced BT electrode placement switch at V2).
H2: Individualized amplitude arm will have improved cognitive outcomes (DKEFS-Verbal Fluency
