Key result
Electroconvulsive therapy abstract discusses seizure threshold variability but reports no new study results.
Why the study?
Because protocols for seizure threshold determination are not standardized and seizure threshold varies widely, information about typical seizure thresholds is needed to optimize efficacy and minimize cognitive side effects.
What is the typical electrical charge required to induce a seizure during initial dose titration using right unilateral brief pulse electroconvulsive therapy?
What is the typical electrical charge required to induce a seizure during initial dose titration using right unilateral brief pulse electroconvulsive therapy?
Information about typical seizure thresholds during initial ECT dose titration can help guide clinical practice to minimize cognitive side effects while maintaining efficacy.
No results on ECT seizure thresholds reported; leaves open optimal initial dosing to balance efficacy and cognitive effects.
Minimizing cognitive side effects of electroconvulsive therapy (ECT) while maintaining clinical efficacy is a key challenge. Given that the electrical charge required to induce a seizure varies by as much as 30-fold among patients [1], and that clinical efficacy and side effects of ECT depend strongly on the dose applied relative to the individual seizure threshold [2], many providers have adopted routine seizure threshold determination at the time of first treatment. As these protocols are not standardized, and likely vary based on the ECT electrode placement and stimulus parameters, information about the typical seizure threshold would help guide clinical practice.

Luccarelli et al. (2020) studied this question. Right unilateral brief pulse electroconvulsive therapy was evaluated on Electrical charge required to induce a seizure. The abstract provides only background information on the variability of electrical charge required to induce a seizure during electroconvulsive therapy, with no study results reported.
