Purpose of review Transcranial direct current stimulation (tDCS) is a noninvasive method of brain stimulation that has been increasingly tested for the treatment of neuropsychiatric disorders. It has useful characteristics, such as low cost, ease of use, reliable sham methodology, and relatively powerful effects on cortical excitability. Because of its potential to modulate cortical excitability noninvasively, tDCS has been tested for the treatment of depression for several decades. Therefore… 
Non-Invasive Brain Stimulation for Enhancement of Corticospinal Excitability and Motor Performance
This narrative review describes characteristics of different tCS paradigms, and summarises safety issues, the mechanisms of tDCS-induced neuroplasticity, limitations of current state of knowledge in the literature, tool that could be used to understand brain plasticity effects in motor regions and tool that is used to understanding motor learning effects.
Transcranial direct current stimulation - what is the evidence for its efficacy and safety?
A number of recent studies suggest that tDCS is safe and may be efficacious in the treatment of a variety of psychiatric and neurological disorders, including major depressive disorder, chronic neuropathic pain, and stroke.
Neuromodulation for Neuropsychiatric Disorders: Novel Techniques -Vagus Nerve Stimulation, Transcranial Magnetic Stimulation, Transcranial Direct Current Stimulation, and Deep Brain Stimulation
The last two decades have seen the development of several neuromodulation techniques that have been applied to the problem of severe, medication-refractory depression – notably vagus nerve
Using Transcranial Direct Current Stimulation to Treat Depression in HIV-Infected Persons: The Outcomes of a Feasibility Study
Findings support feasibility and clinical potential of tDCS for HIV-MDD patients, and justify larger-sample, sham-controlled trials.
Neuromodulation approaches for the treatment of major depression: challenges and recommendations from a working group meeting.
Clinicians should consider all the treatment options including invasive and non-invasive neuromodulation approaches for major depressive disorder, which is a chronic and incapacitating condition with a high prevalence.
Brain stimulation treatments in bipolar disorder: A review of the current literature
Brain stimulation in BD is derived from its use in unipolar depression, however, there are many important differences between these two disorders and more studies with a systematic approach need to be conducted on larger samples of bipolar patients with treatment-resistant characteristics.
Transcutaneous Spinal Direct Current Stimulation
It is argued that, by focally modulating spinal excitability, tsDCS could provide a novel therapeutic tool complementary to drugs and invasive SCS in managing various pathologic conditions, including pain.
Transcranial direct current stimulation: electrode montage in stroke
A small sham controlled cross-over clinical trial is important to provide additional data on the clinical effects of tDCS in stroke and for planning and designing future large tDCS trials in patients with stroke.
Brain transcranial direct current stimulation modulates motor excitability in mice
The feasibility of tDCS in mice suggests the potential applicability of this technique to assess the potential therapeutic options of brain polarization in animal models of neurological and neuropsychiatric diseases.


Treatment of major depression with transcranial direct current stimulation.
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.
Cognitive effects of repeated sessions of transcranial direct current stimulation in patients with depression
Results from a preliminary double-blind, randomized, controlled study that evaluated the cognitive adverse effects of five sessions of tDCS of the left dorsolateral prefrontal cortex (DLPFC) in patients with major depression are reported.
Transcranial magnetic stimulation in the treatment of depression.
Most data support an antidepressant effect of high-frequency repetitive TMS administered to the left prefrontal cortex, and TMS promises to provide insights into the pathophysiology of depression through research designs in which the ability of TMS to alter brain activity is coupled with functional neuroimaging.
Neurostimulatory therapeutics in management of treatment-resistant depression with focus on deep brain stimulation.
Although deep brain stimulation is the most invasive of the neurostimulatory treatments developed to date, it may hold significant promise in alleviating symptoms and improving the quality of life for patients with the most severe and disabling mood disorders.
