    Electroconvulsive therapy (ECT) showed greater improvement for endogenous depression compared to sham ECT, but benefits were modest and temporary. Memory function did not differ long-term between groups.

    Area of Science:

    • Psychiatry
    • Neurology
    • Clinical Psychology

    Background:

    • Endogenous depression is a severe mood disorder.
    • Electroconvulsive therapy (ECT) is a treatment option for severe depression.
    • The efficacy and long-term effects of ECT require further investigation.

    Purpose of the Study:

    • To compare the effectiveness of real ECT versus simulated ECT in patients with endogenous depression.
    • To assess the short-term and long-term outcomes of ECT for depression.
    • To evaluate the impact of ECT on memory function.

    Main Methods:

    • A randomized controlled trial involving 70 patients with endogenous depression.
    • Patients were allocated to receive either real ECT or simulated ECT (eight sessions).

  • Outcomes were assessed using psychiatrists' ratings and memory tests at various follow-up points.

    • Main Results:

    • Real ECT resulted in significantly greater improvement than simulated ECT in the short term (p < 0.01).
    • Both groups showed considerable improvement over the 4-week treatment period.
    • No significant differences in improvement or memory function were observed at one-month and six-month follow-up.

    Conclusions:

    • The therapeutic benefits of ECT for depression are of lesser magnitude and more transient than sometimes claimed.
    • While ECT offers short-term benefits, its long-term advantages over simulated treatment are limited.
    • ECT may cause temporary memory impairment during treatment, but long-term memory function is not significantly affected.
