The effect of the interval-between-sessions on prefrontal transcranial direct current stimulation (tDCS) on cognitive outcomes: a systematic review and meta-analysis

A systematic review and meta-analysis was performed of experimental studies published in PubMed, Science Direct, and other databases from the first data available to February 2016 to show that anodal vs. sham tDCS significantly decreased response times and increased accuracy, and specifically for the executive functioning tasks, in a sample of healthy participants and neuropsychiatric patients.

Transcranial direct current stimulation in attention-deficit hyperactivity disorder: A meta-analysis of neuropsychological deficits

Overall, this meta-analysis supports a beneficial effect of tDCS on inhibitory control and WM in ADHD with a small-to-medium effect size.

Is cathodal prefrontal transcranial direct current stimulation capable of affecting inhibitory control and sustained attention? A single-blind, crossover, sham-controlled study

C-tDCS over the l-DLPFC of neurologically intact young individuals did not affect performance in Stroop Test accuracy or in reaction times, irrespective of subject gender, raising the possibility that c- tDCS inhibitory effects, well documented for the primary motor area, do not necessarily apply to higher order associative areas.

Cognitive Effects of Transcranial Direct Current Stimulation in Healthy and Clinical Populations: An Overview.

The tDCS literature currently indicates that the effects of tDCS on cognitive measures are less robust and less predictable compared with the more consistent effects on motor outcomes and a notable difference in the consistency of single-session and longitudinal designs.

A systematic review and meta-analysis of transcranial direct-current stimulation effects on cognitive function in patients with Alzheimer’s disease

Improved memory and general cognitive function in patients with AD was shown in this meta-analysis, and due to the small number of studies and the high heterogeneity of the data, more high-quality studies using standardized parameters and measures are needed before tDCS can be considered as a treatment for AD.

Transferability of cathodal tDCS effects from the primary motor to the dorsolateral prefrontal cortex: a multimodal TMS-EEG study

The results indicate a dosage-dependent nonlinear neurophysiological effect of motor cortex tDCS, which is not one-to-one transferable to prefrontal tDCS.

Effects of High-Definition Transcranial Direct Current Stimulation (HD-tDCS) of the Intraparietal Sulcus and Dorsolateral Prefrontal Cortex on Working Memory and Divided Attention

A novel type of focalised, non-invasive brain stimulation, High-Definition transcranial Direct Current Stimulation (HD-tDCS) was applied to the regions subserving working memory and divided attention processes, the left intraparietal sulcus (IPS) and left dorsolateral prefrontal cortex (LDLPFC).

Investigating the Role of Current Strength in tDCS Modulation of Working Memory Performance in Healthy Controls

Results revealed no significant improvements in participants’ accuracy, but a significant interaction was found with respect to current strength and time for accurate reaction time, providing partial support for the hypothesis that current strength may affect aspects of WM performance.

Modulating Memory Performance in Healthy Subjects with Transcranial Direct Current Stimulation Over the Right Dorsolateral Prefrontal Cortex

It is shown that cathodal tDCS of the right DLPFC can also improve recognition memory in healthy subjects, complementing the majority of previous studies, reporting long term memory facilitations following left prefrontal anodAL tDCS.
