Repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) are non-invasive brain stimulation methods that became widely used as therapeutic tools during the past two decades especially in cases of depression and schizophrenia. Low frequency rTMS and cathodal effect of tDCS inhibits cortical functioning while high frequency and anodal effect of tDCS have the opposite effect. Prolonged and repetitive application of either methods leads to changes in… 
Transcranial magnetic stimulation in the treatment of obsessive–compulsive disorder: current perspectives
TLDR
Improved understanding of the therapeutic effects of rTMS in OCD will support fine-tuning of the method and help determine how to best optimize the approach via rT MS or dTMS to achieve clinically relevant results.
Immediate Effects of Transcranial Direct Current Stimulation on Obsession-Induced Anxiety in Refractory Obsessive-Compulsive Disorder: A Pilot Study
TLDR
Cathode tDCS could be potentially used to regulate obsession-induced anxiety in refractory OCD patients and a statistically significant decrease in the severity of the obsession- induced anxiety was found as a result of cathode tDCs in comparison with the anode and sham stimulation.
New Directions in the Use of Brain Stimulation Interventions in Patients with Obsessive-Compulsive Disorder.
TLDR
Through the analysis of controlled studies, meta-analyses, and International treatment guidelines, the present article is aimed at providing the state of the art on the use of brain stimulation techniques for the treatment of OCD.
Prefrontal tDCS and sertraline in obsessive compulsive disorder: a case report and review of the literature
TLDR
The first report on a patient with treatment-refractory OC disorder treated with sertraline and an enhanced prefrontal tDCS protocol with a classic left-anodal/right cathodal montage experiencing a 22% reduction of OC symptoms as well as reduction in depression and anxiety symptoms is provided.
Repetitive Transcranial Magnetic Stimulation to Supplementary Motor Area in Refractory Obsessive-Compulsive Disorder Treatment: a Sham-Controlled Trial
TLDR
Low-frequency repetitive transcranial magnetic stimulation applied to the presupplementary area seems ineffective for the treatment of obsessive-compulsive disorder patients, at least in severe and drug-refractory cases such as those included in this study.
Brain Stimulation in Obsessive-Compulsive Disorder (OCD): A Systematic Review
TLDR
Different brain stimulation techniques are promising as an add-on treatment of refractory OCD, although studies frequently reported inconsistent results.
A Meta-Analysis of the Effectiveness of Different Cortical Targets Used in Repetitive Transcranial Magnetic Stimulation (rTMS) for the Treatment of Obsessive-Compulsive Disorder (OCD)
TLDR
The meta-analysis implies that low frequency rTMS applied over the supplementary motor area may offer the greatest effectiveness in the treatment of OCD, which implies that future large-scale studies focus on the supplementaryMotor area and include follow-up periods of 12 weeks or more.

TLDR
Three target areas have already been selected of which the supplementary motor area in particular and the orbitofrontal cortex seem to be the most promising in terms of potential efficacy and could more accurately be targeted with the help of neuronavigational techniques.

Treatment of major depression with transcranial direct current stimulation.
TLDR
The effects of 5 days of anodal stimulation of the left dorsolateral prefrontal cortex in 10 patients with major depression are investigated, finding a significant decrease in the Hamilton Depression Rating Scale and Beck Depression Inventory scores when compared with baseline that was not observed in patients that received sham stimulation.
Augmentation effect of repetitive transcranial magnetic stimulation over the supplementary motor cortex in treatment refractory patients with obsessive compulsive disorder
TLDR
Low-frequency repetitive transcranial magnetic stimulation over the SMA appears a promising treatment strategy as an add-on treatment in treatment-refractory patients of OCD.
Examining transcranial direct-current stimulation (tDCS) as a treatment for hallucinations in schizophrenia.
TLDR
The results show promise for treating refractory auditory verbal hallucinations and other selected manifestations of schizophrenia.
Repetitive transcranial magnetic stimulation for the treatment of obsessive compulsive disorder: a double-blind controlled investigation
TLDR
Two weeks of rTMS over the left DLPFC is ineffective for treatment-resistant OCD and over 20 sessions, there was a significant reduction in total YBOCS scores, but not after controlling for depression.
Right prefrontal repetitive transcranial magnetic stimulation in obsessive-compulsive disorder: a double-blind, placebo-controlled study.
TLDR
Low-frequency rTMS of the right prefrontal cortex failed to produce significant improvement of OCD and was not significantly different from sham treatment.
