Bilateral sinusoidal ECT following poor response to five unilateral brief-pulse ECTs.

T W McAllister, T R Price, R B Ferrell

    The Journal of Clinical Psychiatry
    |October 1, 1985
    PubMed
    Summary

    Twelve of 31 depressed patients did not respond to brief-pulse electroconvulsive therapy (ECT). However, eight of these patients fully responded to sinusoidal electroconvulsive therapy (ECT), suggesting stimulus type impacts treatment outcomes.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Clinical Medicine

    Background:

    • Electroconvulsive therapy (ECT) is a common treatment for severe depression.
    • Treatment resistance remains a challenge in managing major depressive disorder.
    • Different ECT stimulus parameters may influence therapeutic efficacy.

    Purpose of the Study:

    • To investigate the efficacy of switching ECT stimulus type in treatment-resistant depression.
    • To compare patient response to unilateral brief-pulse versus bilateral sinusoidal ECT.

    Main Methods:

    • A cohort of 31 patients with major depressive disorder was studied.
    • Twelve patients initially unresponsive to five unilateral brief-pulse ECT sessions were identified.
    • These 12 patients subsequently received bilateral sinusoidal ECT.

    Main Results:

    • Eight out of the 12 non-responsive patients achieved a full therapeutic response after switching to bilateral sinusoidal ECT.
    • This indicates a significant treatment effect in a subset of non-responders.

    Conclusions:

    • The type of electroconvulsive therapy (ECT) stimulus may play a critical role in achieving therapeutic outcomes for some patients with depression.
    • Bilateral sinusoidal ECT can be an effective alternative for patients who do not respond to unilateral brief-pulse ECT.
