Before And After

Background.Impaired emotion regulation may underlie exaggerated emotional reactivity in patients with obsessive compulsive disorder (OCD), yet instructed emotion regulation has never been studied in the disorder.Method.This study aimed to assess the neural correlates of emotion processing and regulation in 43 medication-free OCD patients and 38 matched healthy controls, and additionally test if these can be modulated by stimulatory (patients) and inhibitory (controls) repetitive transcranial magnetic stimulation (rTMS) over the left dorsolateral prefrontal cortex (dlPFC). Participants performed an emotion regulation task during functional magnetic resonance imaging before and after a single session of randomly assigned real or sham rTMS. Effect of group and rTMS were assessed on self-reported distress ratings and brain activity in frontal-limbic regions of interest.Results.Patients had higher distress ratings than controls during emotion provocation, but similar rates of distress reduction after voluntary emotion regulation. OCD patients compared with controls showed altered amygdala responsiveness during symptom provocation and diminished left dlPFC activity and frontal-amygdala connectivity during emotion regulation. Real v. sham dlPFC stimulation differentially modulated frontal-amygdala connectivity during emotion regulation in OCD patients.Conclusions.We propose that the increased emotional reactivity in OCD may be due to a deficit in emotion regulation caused by a failure of cognitive control exerted by the dorsal frontal cortex. Modulatory rTMS over the left dlPFC may influence automatic emotion regulation capabilities by influencing frontal-limbic connectivity.

BACKGROUND Background: Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive procedure in which brain neural activity is stimulated by direct application of a magnetic field to the scalp. rTMS is considered a therapeutic tool in various neuropsychiatric conditions. Since its approval in Canada in 2002 and despite its wide and continuous usage for the management of depressive disorders, knowledge on the use of rTMS for Obsessive-Compulsive Disorder (OCD) is sparse. OBJECTIVE Objectives: This scoping review seeks to; (i) explore the relevant literature available regarding the use of rTMS as a mode of treatment for OCD; (ii) To evaluate the evidence to support the use of rTMS as a treatment option for OCD. METHODS Method: We electronically conducted data search in five research databases (MEDLINE, CINAHL, Psych INFO, SCOPUS, and EMBASE) using all identified keywords and index terms across all the data bases to identify empirical studies and randomized controlled trials. We included articles published with randomized control designs which aimed at the treatment of OCD with rTMS. Only full-text published articles written in English were reviewed. Review articles on treatment for conditions other than OCD were excluded. RESULTS NA CONCLUSIONS Conclusion: The application of rTMS as a treatment intervention for OCD looks promising despite diversity in terms of outcomes and clinical significance. Further studies with well-defined stimulation parameters are needed in order to be able to draw a definite conclusion of its clinical effectiveness in the treatment of OCD.

IntroductionObsessive-compulsive disorder (OCD) is a frequently reported comorbid disorder (20–30%) in patients with anorexia nervosa (AN). Increasing evidence suggests that repetitive transcranial magnetic stimulation (r-TMS) may be effective in the treatment of refractory OCD and to a lesser extent in AN. Hereby, different target areas: supplemental motor area (SMA) and orbitofrontal cortex (OFC) and dorsolateral prefrontal cortex in AN. We report two patients with enduring AN and comorbid treatment resistant OCD treated with r-TMS.MethodsBoth female patients (34 and 26 years respectively) were hospitalized at the Eating Disorder Unit at the Ghent University Hospital. Treatment responses were evaluated with Yale Brown Obsessive Compulsive Scale (Y-BOCS) and weight gain. Inhibitory continuous thetaburst stimulation (cTBS) of the SMA followed by cTBS of the OFC was conducted during 20 sessions, 5 sessions a week, during 4 weeks. Stimulation intensity was respectively 100% and 80% of the motor treshold.ResultsAfter cTBS treatment Y-BOCS score of both patients decreased (31 to 24 and 31 to 23 respectively). Only one patient showed a 10% increase of weight. The treatment was well tolerated. No significant side effects were reported.ConclusionTreatment resistant comorbid OCD in patients with AN may be succesfully treated with cTBS.Disclosure of interestThe authors have not supplied their declaration of competing interest.
