Objectives. Electroconvulsive therapy (ECT) is an effective treatment for severe depression. Electroencephalogram (EEG) measures between ECT sessions seem to be related to the antidepressant efficacy of ECT. In this naturalistic cohort study, we examine longitudinal effects of ECT on interhemispheric EEG coherence measures during seizure activity and its relation to the antidepressant efficacy. Methods. This study included 65 patients diagnosed with severe depressive disorder. Depressive symptoms were rated according to the Montgomery-Åsberg Depression Rating Scale before and after the course of ECT. Frequency-specific ictal interhemispheric (fp1-fp2) EEG coherence measures were established during the first and each consecutive sixth treatment session. Linear mixed-effect models were used to determine longitudinal changes in ictal coherence measures during the course of ECT and its relation to treatment efficacy. Results. Ictal interhemispheric coherence in the theta and alpha frequency bands increased over the course of treatment, whereas no significant change was found for the delta and beta frequency bands. A main effect of treatment efficacy on the interhemispheric coherence in the delta and theta band was revealed. However, the longitudinal effects of ECT were not associated with treatment efficacy. Conclusion. The current study suggests that interhemispheric coherence during ECT-induced seizures increases over the course of treatment. Furthermore, these longitudinal effects seem to be unrelated to the antidepressant efficacy of ECT. These findings contribute to the understanding of the mechanism of action of ECT.

We present the case of a patient with previous psychiatric illness, acutely exacerbated by thyroid storm due to Graves’ disease, in whom treatment with antipsychotics induced catatonia. These associations are extremely rare and may be confused with Hashimoto’s encephalopathy, especially in the presence of anti-thyroid antibodies in cerebrospinal fluid. The treatment consists in the control of the triggering disease (in this case the resolution of the thyrotoxicosis) and the use of benzodiazepines. However, in some cases, the resolution of psychiatric symptoms is partial and may require the use of electroconvulsive therapy.

In an ongoing attempt to improve efficacy of electroconvulsive therapy (ECT) while minimizing side-effects, both different electrode placements and stimulus parameters have been studied. It has been shown that the traditional bitemporal electrode placement and modern techniques such as bifrontal and unilateral ECT are efficacious, depending on the stimulus used. Modern ECT-devices deliver a square wave brief pulse stimulus. An unresolved issue in the use of brief pulse stimulation concerns the optimal pulse width. It has been suggested that the use of a stimulus with an ultra brief (UB) pulse width, i.e. 0.3 ms, is substantially more efficient in seizure induction, thus needing less energy, and producing less cognitive side-effects than standard pulse width (i.e. 0.5-2 ms) stimulation. There has been a concern, however, of lower antidepressant efficacy of UB ECT, with patients needing additional treatment sessions. Moreover, it has been suggested that the diminished antidepressive efficacy is encountered solely with the combination of an ultra-brief pulse width and bilateral electrode placement, as compared to unilateral UB ECT or standard pulse ECT. In a randomized trial, the antidepressive efficacy and cognitive side-effects of bifrontal and right unilateral UB ECT were compared. It was shown that, using an ultra-brief pulse width, BF ECT is as efficacious as UL ECT, although patients receiving UL ECT achieved response/remission-criteria after a smaller number of treatments. In both treatment conditions there was an improvement of cognitive function, both during and after the treatment course.
