    Abstract:
    OBJECTIVE: The cognitive side-effects of bifrontal (BF) and right unilateral (UL) ultra-brief pulse (0.3 ms) electroconvulsive therapy (ECT) were compared, in the treatment of patients with a depressive episode. METHOD: Neuropsychological functioning in patients with a medication refractory depressive episode, that were treated with a course of BF ultra-brief ECT at 1.5 times seizure threshold (ST) or UL ultra-brief ECT at 6 times ST, by random assignment, was assessed before treatment, and 1 and 6 weeks after the treatment course, by a blinded rater. RESULTS: Of the 64 patients that were included, 32 (50%) received BF ECT, and 32 (50%) received UL ECT, by random assignment. Neuropsychological testing 1 and 6 weeks after treatment was performed by 30 (93.75%) and 19 (59.37%) patients, respectively, in the BF-group and 29 (90.62%) and 20 (62.50%), respectively, in the UL-group. There was no deterioration in any of the neuropsychological measures. Patients rated their memory as clearly improved after treatment. There were no significant differences between the patients given BF ECT and those given UL ECT. CONCLUSIONS: Ultrabrief pulse ECT, used either in combination with a UL electrode position and a stimulus of 6 times ST, or a BF electrode position with a stimulus of 1.5 times ST, are effective antidepressant techniques, that do not have a deleterious effect on cognitive function.
