The dose-response ratio in electroconvulsive therapy a preliminary study.

T R Price, T B Mackenzie, G J Tucker

    Archives of General Psychiatry
    |September 1, 1978
    PubMed
    Summary

    Younger age correlated with better electroconvulsive therapy (ECT) response. Initial cognitive and affective states also predicted overall ECT improvement, suggesting key variables for treatment optimization.

    Area of Science:

    • Neuroscience
    • Psychiatry
    • Clinical Psychology

    Background:

    • Electroconvulsive therapy (ECT) is a vital treatment for severe mood disorders.
    • Understanding patient variables influencing ECT efficacy is crucial for personalized treatment.

    Purpose of the Study:

    • To identify pretreatment patient characteristics correlating with electroconvulsive therapy (ECT) dose-response and treatment outcomes.
    • To explore the relationship between age, cognitive function, affective state, and ECT effectiveness.

    Main Methods:

    • 14 patients undergoing ECT were assessed daily using self-report affective scales, cognitive tests, and finger-tapping speed.
    • Dose-response ratios and treatment outcome measures were derived from daily assessments.
    • Correlational analyses were performed to link pretreatment variables with ECT response.

    Main Results:

    • A more favorable ECT dose-response ratio was observed in younger patients.
    • The dose-response ratio of early ECT treatments correlated with age.
    • Initial cognitive impairment and affective severity predicted greater overall affective improvement with ECT.

    Conclusions:

    • Age is a significant factor influencing ECT dose-response, with younger individuals showing more favorable ratios.
    • Early treatment response and baseline patient condition (cognitive and affective) are strong predictors of overall treatment success in ECT.
    • These findings have implications for tailoring ECT protocols and patient selection for improved outcomes.
