    Electroconvulsive therapy (ECT) can trigger manic episodes in some depressed patients. Patients with earlier onset, longer illness duration, and more hospitalizations may face a higher risk of ECT-associated mania.

    Area of Science:

    • Psychiatry
    • Neuroscience
    • Clinical Psychology

    Background:

    • Electroconvulsive therapy (ECT) is a widely used treatment for severe depression.
    • The potential for ECT to induce manic episodes is a recognized but not fully understood phenomenon.

    Purpose of the Study:

    • To investigate the incidence and clinical characteristics of manic episodes following electroconvulsive therapy (ECT) in a cohort of depressed patients.
    • To identify patient-specific factors associated with an increased risk of ECT-induced mania.

    Main Methods:

    • A cohort of 94 patients diagnosed with depressive illness received electroconvulsive therapy (ECT).
    • Patients who developed a manic episode post-ECT were identified and analyzed.
    • Demographic and clinical data of these patients were compared with matched controls.

    Main Results:

    • A manic episode developed in 6.4% of the 94 patients treated with ECT.
    • The affected patients were distributed across primary unipolar depression, bipolar affective disorder, and schizoaffective disorder diagnoses.
    • Compared to controls, patients experiencing ECT-associated mania had an earlier age of onset, longer illness duration, and more prior psychiatric hospitalizations.

    Conclusions:

    • While a direct causal link remains unproven, specific clinical characteristics appear to elevate the risk of mania following ECT.
    • The findings suggest that careful patient selection and monitoring are crucial for individuals undergoing ECT, particularly those with a history of mood lability or earlier disease onset.
