Predictors of post-electroconvulsive therapy delirium: a prospective randomized study from an Indian tertiary care centre.

Early post-ECT delirium occurred in 65 patients (72.2%) at 15 minutes, whereas only 11 patients (12.2%) remained delirious at 30 min.

Among patients with delirium at 15 min, 54 (83.1%) recovered by 30 min.

Longer seizure duration remained independently associated with increased odds of delirium at 15 min (adjusted OR = 1.09, 95% CI: 1.04-1.18, p = 0.004).
