Use of ultrabrief pulse width electroconvulsive therapy to induce therapeutic seizures in an elderly patient with a high seizure threshold: a case report

Abstract

Objective: This case report describes a 73-year-old man suffering from unipolar major depression with melancholic features, in whom treatment with electroconvulsive therapy (ECT) proved difficult due to inadequate seizure generation. Methods: A number of augmentation strategies were trialled in an attempt to improve seizure quality. Pre-ECT and Post-ECT measurement of symptoms, quality of life and cognition were undertaken with a variety of validated scales. Results: The single most efficacious strategy to elicit therapeutic seizures was the use of right unilateral (RUL) electrode placement with an ultrabrief pulse width. The patient subsequently had a resolution of his depressive illness, with a concomitant improvement in cognitive functioning. Conclusion: This case demonstrates that a number of ECT augmentation strategies can be used in routine clinical practice for patients with high seizure thresholds. It highlights that UB pulse width may be considered earlier in the treatment course for patients in whom conventional brief pulse ECT fails to generate effective seizures.
