Large treatment effect with extended home-based transcranial direct current stimulation over dorsolateral prefrontal cortex in fibromyalgia: A Proof of Concept Sham-Randomized Clinical Study.

This randomized, double-blind controlled trial tested the hypothesis that sixty sessions of home-based anodal (a)-transcranial direct current stimulation (tDCS) over dorsolateral prefrontal cortex (DLPFC) would be better than home-based sham-tDCS to improve the widespread pain and the disability-related to pain (DRP). tDCS was self-administered with a specially developed device after in-person training. The anodal-tDCS (2mA for 30 mins) over the left DLPFC was self-administered with a specially developed de...

Transcranial Direct Current Stimulation over the Left Dorsolateral Prefrontal Cortex Improves Inhibitory Control and Endurance Performance in Healthy Individuals.

The dorsolateral prefrontal cortex (DLPFC) is a crucial brain region for inhibitory control, an executive function essential for behavioural self-regulation. Recently, inhibitory control has been shown to be important for endurance performance. Improvement in inhibitory control were found following transcranial direct current stimulation (tDCS) applied over the left DLPFC (L-DLPFC). This study examined the effect tDCS on both an inhibitory control and endurance performance in a group of healthy individuals....

Transcranial direct current stimulation improves risky decision making in women but not in men: a sham-controlled study.

Behavioral and anatomical sex-related differences have been traditionally found in decision-making processes assessed by Iowa Gambling Task (IGT). So far, the administration of transcranial direct current stimulation (tDCS) over orbitofrontal regions has shown an enhancing effect over decision-making. However, it is unknown whether there is a sex-dependent effect of stimulation in decision-making, a key question considering previous differences between men and women in IGT and the influence of individual di...

Polarity- and Intensity-Independent Modulation of Timing During Delay Eyeblink Conditioning Using Cerebellar Transcranial Direct Current Stimulation.

Delay eyeblink conditioning (dEBC) is widely used to assess cerebellar-dependent associative motor learning, including precise timing processes. Transcranial direct current stimulation (tDCS), noninvasive brain stimulation used to indirectly excite and inhibit select brain regions, may be a promising tool for understanding how functional integrity of the cerebellum influences dEBC behavior. The aim of this study was to assess whether tDCS-induced inhibition (cathodal) and excitation (anodal) of the cerebell...

Systematic review and meta-analysis of placebo/sham controlled randomised trials of spinal cord stimulation for neuropathic pain.

The aims of this study review were to: systematically identify the current evidence base of randomised controlled trials (RCTs) of spinal cord stimulation (SCS) placebo (or 'sham') trials for neuropathic pain and (2) to undertake a meta-analysis to investigate the effectiveness of SCS when compared with a placebo comparator arm. Electronic databases were searched from inception until January 2019 for RCTs of SCS using a placebo/sham control. Searches identified eight eligible placebo-controlled randomised t...

Anodal High-definition Transcranial Direct Current Stimulation over the Posterior Parietal Cortex Modulates Approximate Mental Arithmetic.

The representation and processing of numerosity is a crucial cognitive capacity. Converging evidence points to the posterior parietal cortex (PPC) as primary "number" region. However, the exact role of the left and right PPC for different types of numerical and arithmetic tasks remains controversial. In this study, we used high-definition transcranial direct current stimulation (HD-tDCS) to further investigate the causal involvement of the PPC during approximative, nonsymbolic mental arithmetic. Eighteen he...

Transcranial direct current stimulation for the treatment of generalized anxiety disorder: A randomized clinical trial.

Generalized anxiety disorder (GAD) is a common condition with current treatments being only moderately effective. Non-invasive brain stimulation techniques might provide a novel approach for treating GAD. Transcranial direct current stimulation (tDCS) has shown promising efficacy and tolerability for major depression but has not been investigated for GAD yet. Thus, we investigated the effects of tDCS on patients with GAD.

Exploring the effects of Transcranial Direct Current Stimulation over the prefrontal cortex on working memory: a cluster analysis approach.

Experimental-design specific changes in spontaneous EEG and during intermittent photic stimulation by High Definition transcranial Direct Current Stimulation.

EEG as a biomarker of neuromodulation by High Definition transcranial Direct Current Stimulation (HD-tDCS) offers promise as both techniques are deployable and can be integrated into a single head-gear. The present research addresses experimental design for separating focal EEG effect of HD-tDCS in the '4-cathods x 1-anode' (4x1) montage over the left motor area (C3). We assessed change in offline EEG at the homologous central (C3, C4), and occipital (O1, O2) locations. Interhemispheric asymmetry was access...

High-definition transcranial direct current stimulation in anorexia nervosa: A pilot study.

Anorexia nervosa (AN) is a serious psychiatric condition often associated with poor outcomes. Biologically informed treatments for AN, such as brain stimulation, are lacking, in part due to the unclear nature of the neurobiological contributions to the illness. However, recent research has suggested a specific neurobiological target for the treatment of AN, namely stimulation of the inferior parietal lobe (IPL). The aim of this study was to stimulate-noninvasively-the left IPL in individuals with AN using h...

Current intensity- and polarity-specific online and aftereffects of transcranial direct current stimulation: An fMRI study.

Transcranial direct current stimulation (tDCS) induces polarity- and dose-dependent neuroplastic aftereffects on cortical excitability and cortical activity, as demonstrated by transcranial magnetic stimulation (TMS) and functional imaging (fMRI) studies. However, lacking systematic comparative studies between stimulation-induced changes in cortical excitability obtained from TMS, and cortical neurovascular activity obtained from fMRI, prevent the extrapolation of respective physiological and mechanistic ba...
