| Title: | Distinctive neurocognitive effects of repetitive transcranial magnetic stimulation and electroconvulsive therapy in major depression. | | Author(s): | Schulze-Rauschenbach SC, Harms U, Schlaepfer TE, Maier W, Falkai P, Wagner M. | | Source: | Br J Psychiatry. 2005 May;186:410-6. | | Abstract: | Studies have compared electroconvulsive therapy (ECT) and repetitive transcranial magnetic stimulation (rTMS) with regard to clinical efficacy in the treatment of depression, but no study has yet addressed the differential impact on cognition. AIMS: To compare the neurocognitive effects of unilateral ECT and rTMS. METHOD: Thirty patients with treatment-refractory non-psychotic major depression received an average of ten treatments with either unilateral ECT or left prefrontal rTMS and were assessed for objective and subjective cognitive impairments before and about a week after treatment. RESULTS: Treatment response was comparable (46% of the ECT group and 44% of the rTMS group showed a reduction of 50% or more in Hamilton Rating Scale for Depression scores). In patients treated with rTMS, cognitive performance remained constant or improved and memory complaints alleviated, whereas in the ECT group memory recall deficits emerged and memory complaints remained. CONCLUSIONS: In contrast to unilateral ECT, rTMS has no adverse memory effects. |

| | Title: | Motor cortical excitability in depressive patients after electroconvulsive therapy and repetitive transcranial magnetic stimulation. | | Author(s): | Bajbouj M, Luborzewski A, Danker-Hopfe H, Lang UE. | | Source: | J ECT. 2005 Dec;21(4):243-5. | | Abstract: | Electroconvulsive therapy (ECT) and repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral prefrontal cortex are brain stimulation techniques that are used as therapeutic interventions in major depression. However, the exact therapeutic mode of action needs further clarification. In this case report, we describe the impact of these stimulation techniques on motor cortical excitability, as revealed by transcranial magnetic stimulation-elicited motor-evoked potentials in 2 patients who received consecutively both rTMS and ECT. Both patients showed a decrease in motor cortical excitability after response to antidepressant brain stimulation, whereas parameters of motor cortical excitability remained unchanged after the first non-successful intervention. These results suggest that both ECT and rTMS may have an impact on parameters of motor cortical neuronal excitability. Furthermore, measurement of motor cortical excitability may be a useful tool for investigating and monitoring inhibitory brain effects of different antidepressant stimulation techniques. |

| | Title: | Repetitive transcranial magnetic stimulation and electroconvulsive therapy: complementary or competitive therapeutic options in depression? | | Author(s): | Fitzgerald P. | | Source: | Australas Psychiatry. 2004 Sep;12(3):234-8. | | Abstract: | To examine issues pertaining to the potential clinical roles of repetitive transcranial magnetic stimulation (rTMS) and the relationship of these to the use of electroconvulsive therapy (ECT). METHODS: A review of studies was carried out comparing the use of rTMS and ECT, with consideration of issues relating to the populations in which rTMS may be applied. RESULTS: There have been a number of randomized comparisons of rTMS and ECT. There are limitations with these studies, but in general they indicate that in non-psychotic patients rTMS appears to have a similar rate of response to ECT and certainly seems to have meaningful clinical effects. There are a number of clinical subpopulations in whom rTMS, but not ECT, is suitable, and assessment of the effectiveness of TMS in these populations is required. CONCLUSIONS: Repetitive TMS and ECT are likely to prove to be complementary clinical tools and the introduction of clinical programmes with rTMS will enhance patient options rather than replace the use of ECT. |
