    Summary

    Electroconvulsive therapy (ECT) may lead to cognitive impairments. Some patients experience lasting cognitive deficits after ECT, even after accounting for depression and medication effects.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Cognitive Psychology

    Background:

    • Electroconvulsive therapy (ECT) is a treatment for severe mental health conditions.
    • Concerns exist regarding potential long-term cognitive side effects of ECT.
    • Understanding these effects is crucial for patient care and informed consent.

    Purpose of the Study:

    • To investigate cognitive functioning in individuals reporting persistent adverse effects after ECT.
    • To compare cognitive performance between ECT complainers and control groups.
    • To identify potential cognitive impairments not explained by depression or medication.

    Main Methods:

    • A cohort of 26 subjects reporting permanent unwanted effects post-ECT was recruited.
    • Cognitive function was assessed using a comprehensive battery of 19 tests.
    • Statistical analyses, including analysis of variance/co-variance, were employed for comparison.

    Main Results:

    • Numerous statistically significant differences in cognitive functioning were observed between groups.
    • Many initial differences were attributed to confounding factors like depression severity and medication.
    • However, residual cognitive deficits remained evident in the ECT complaining group post-analysis.

    Conclusions:

    • ECT may be associated with persistent cognitive impairments in some individuals.
    • These impairments may persist even after controlling for depression and medication.
    • Further research is warranted to understand the mechanisms and long-term impact of ECT on cognition.
