Electroconvulsive therapy (ECT) causes disorientation after treatment, particularly after the first session. Disorientation severity varied by person, place, and time, increasing with more treatments.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Clinical Psychology

Background:

  • Electroconvulsive therapy (ECT) is a common treatment for major depression.
  • Disorientation is a known side effect of ECT, but its characteristics require further elucidation.

Purpose of the Study:

  • To investigate the characteristics of postictal and interictal disorientation following ECT in major depression patients.
  • To determine the influence of real versus simulated ECT on disorientation.
  • To explore the relationship between ECT parameters, demographic factors, and disorientation.

Main Methods:

  • Thirty-seven inpatients with major depression were assessed for disorientation after real and simulated ECT sessions.
  • Disorientation was evaluated for person, place, and time, with a temporal gradient analysis.

  • Correlations between seizure duration, electrical stimulus intensity, demographic variables, and disorientation were examined.

    • Main Results:

    • Real ECT, unlike simulated ECT, induced postictal disorientation, which was most pronounced after the first treatment.
    • Disorientation severity followed a gradient: shortest for person, longer for place, and longest for time.
    • Interictal disorientation increased with the number of ECT treatments.
    • Seizure duration and stimulus intensity independently correlated with postictal disorientation length, unaffected by demographic factors.

    Conclusions:

    • ECT-induced postictal disorientation is a real phenomenon, influenced by treatment number and specific stimulus parameters.
    • Interictal disorientation escalates with cumulative ECT exposure.
    • Understanding these disorientation patterns is crucial for managing ECT side effects and optimizing patient care.
