Objective: Despite effective psychological and pharmacological treatments, there is a large unmet burden of illness in post-traumatic stress disorder (PTSD). Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive intervention and a putative treatment strategy for PTSD. The evidence base to date suggests that rTMS targeting the dorsolateral prefrontal cortex (DLPFC), in particular the right DLPFC, leads to improvements in PTSD symptoms. However, optimal stimulation parameters have yet to be determined. In this study, we examine the efficacy of high- and low-frequency rTMS of the right DLPFC using a randomized, double-blind, sham-controlled design in civilian PTSD. Methods: We conducted a 2-week single-site randomized sham-controlled trial of rTMS targeting the right DLPFC. We recruited civilians aged 19 to 70 with PTSD and randomized subjects with allocation concealment to daily 1-Hz rTMS, 10-Hz rTMS, or sham rTMS. The primary outcome was improvement in Clinician Administered PTSD Scale–IV (CAPS-IV). Secondary outcomes included change in depressive and anxiety symptoms. Results: We recruited 31 civilians with PTSD. One 1-Hz-treated patient developed transient suicidal ideation. Analyses revealed significant improvement in CAPS-IV symptoms in the 1-Hz group relative to sham (Hedges’ g = −1.07) but not in the 10-Hz group. This was not attributable to changes in anxious or depressive symptomatology. Ten-Hz stimulation appeared to improve depressive symptoms compared to sham. Conclusion: Low-frequency rTMS is efficacious in the treatment of civilian PTSD. Our data suggest that high-frequency rTMS of the right DLPFC is worthy of additional investigation for the treatment of depressive symptoms comorbid with PTSD.
Widespread negative attitudes toward electroconvulsive therapy (ECT) are present in the general public and among heath care professionals. However, there is evidence to suggest that clinical experience and knowledge of ECT positively improve attitudes toward this treatment. The purpose of this study was to evaluate the effects of an ECT education training program on attitudes toward ECT. Participants were 73 student nurses (91.8% women) and 21 care aid students (81.0% women) undertaking a 6-week rotation in psychiatry at a large provincial psychiatric hospital in British Columbia, Canada. The ECT education training program consisted of a brief lecture, viewing of an educational videotape, familiarization with the ECT equipment, and observation of an ECT treatment. Participants completed a short questionnaire pretraining and posttraining program. Attitudes toward ECT did not substantially differ between the 2 groups. For the entire sample, only 8.5% reported that they were well informed about ECT before the training session. More favorable attitudes were reported upon completion of the ECT education program compared with attitudes reported before training. These findings suggest that attitudes toward ECT increase favorably when individuals are provided with training and experience.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
