The neurobiological basis of bipolar disorders (BD) has received increased attention and several brain regions and brain circuits have been correlated with clinical symptoms. These brain regions and circuits may represent targets for neuromodulation techniques such as transcranial Direct Current Stimulation (tDCS). We systematically reviewed the literature to explore the risks and benefits of tDCS in BD and examined all mood states. Following the PRISMA guidelines, a systematic literature search using several databases was performed from April 2002 to June 2017...

We examined the efficacy and acceptability of non-invasive brain stimulation in adult unipolar and bipolar depression. Randomised sham-controlled trials of transcranial direct current stimulation (tDCS), transcranial magnetic stimulation (TMS) and theta-burst stimulation (TBS), without co-initiation of another treatment, were included. We analysed effects on response, remission, all-cause discontinuation rates and continuous depression severity measures. Fifty-six studies met our criteria for inclusion (N  = 3,058, mean age = 44...

BACKGROUND: Transcranial direct current stimulation (tDCS) of the prefrontal cortex (PFC) has been widely applied in cognitive neurosciences and advocated as a therapeutic intervention, e.g. in major depressive disorder. Although several targets and protocols have been suggested, comparative studies of tDCS parameters, particularly electrode montages and their cortical targets, are still lacking. OBJECTIVE: This study investigated a priori hypotheses on specific effects of prefrontal-tDCS montages by using multimodal functional magnetic resonance imaging (fMRI) in healthy participants...

OBJECTIVES: Implicit regulation of emotions involves medial-prefrontal cortex (mPFC) regions exerting regulatory control over limbic structures. Diminished regulation relates to aberrant mPFC functionality and psychopathology. Establishing means of modulating mPFC functionality could benefit research on emotion and its dysregulation. Here, we tested the capacity of transcranial direct current stimulation (tDCS) targeting mPFC to modulate subjective emotional states by facilitating implicit emotion regulation...

Background/Objective : Non-invasive neuromodulation techniques, such as repetitive Transcranial Magnetic Stimulation (rTMS) and transcranial Direct Current Stimulation (tDCS), have increasingly been investigated for their potential as treatments for neurological and psychiatric disorders. Despite widespread dissemination of these techniques, the underlying therapeutic mechanisms and the ideal stimulation site for a given disorder remain unknown. Increasing evidence support the possibility of non-invasive neuromodulation affecting a brain network rather than just the local stimulation target...

Transcranial direct current stimulation (tDCS) has emerged as a promising new treatment for major depression. While recent randomised, sham-controlled studies found tDCS to have antidepressant effects, it remains to be determined whether a tDCS treatment course may also enhance cognitive function independent of mood effects in depressed patients. This systematic review and individual patient data (IPD) meta-analysis examined cognitive outcomes from randomised, sham-controlled trials of tDCS treatment for major depression...

BACKGROUND: Apathy, commonly defined as loss of motivation, is a symptom frequently encountered in Alzheimer's disease (AD). The treatment of apathy remains challenging in the absence of any truly effective medications. Transcranial magnetic stimulation (rTMS) or transcranial direct current stimulation (tDCS) can improve cognitive disorders, but do not appear to improve apathy. Isolated cognitive training also appears to have no effect on apathy. We propose to test the efficacy of a new procedure for the treatment of apathy in AD patients consisting of a combination of tDCS and cognitive training, based on the latest guidelines for the design of therapeutic trials in this field...

BACKGROUND: Transcranial direct current stimulation (tDCS) above the left dorsolateral prefrontal cortex (lDLPFC) has been widely used to improve symptoms of major depressive disorder (MDD). However, the effects of different stimulation protocols in the entire frontal lobe have not been investigated in a large sample including patient data. METHODS: We used 38 head models created from structural magnetic resonance imaging data of 19 healthy adults and 19 MDD patients and applied computational modeling to simulate the spatial distribution of tDCS-induced electric fields (EFs) in 20 frontal regions...

Transcranial Direct Current Stimulation (tDCS) is a cheap, easy to use, and relatively safe noninvasive brain stimulation technique. It is increasingly used in several indications in psychiatry and neurology, mainly for depression, chronic pain and cognitive decline due to degenerative brain diseases. Its efficacy is probable in depression and must still be confirmed in numerous other indications. Lowcost devices for the general public are easy to find on the internet and are frequently used for non-therapeutic indications, like the improvement of video gamers' performances...

BACKGROUND: While the clinical results from transcranial direct current stimulation (tDCS) for the treatment of depression have been promising, antidepressant effects in patients with medication resistance have been suboptimal. There is therefore a need to further optimise tDCS for medication resistant patients. In this clinical pilot study we examined the feasibility, safety, and clinical efficacy of combining tDCS with a psychological intervention which targets dysfunctional circuitry related to emotion regulation in depression, Cognitive Emotional Training (CET)...

OBJECTIVE: The feasibility and effectiveness of concomitant use of transcranial direct current stimulation (tDCS) with electroconvulsive therapy (ECT) has not been investigated. The study principally aimed at determining whether tDCS when combined with ECT improved the speed of antidepressant response. Secondarily, the ease of generation of seizures during electroconvulsive therapy and cognitive outcomes were investigated. METHODS: Consecutive patients referred for ECT to treat major depression were randomized to tDCS with dorsolateral prefrontal electrode placements (n = 8) or sham (n = 8) used daily and just before thrice weekly, 6 times threshold, right unilateral ultrabrief (0...

Major Depressive Disorder (MDD) is one of the most prevalent psychiatric disorders worldwide. About 20-30% of patients do not respond to the standard psychopharmacological and/or psychotherapeutic interventions. Mounting evidence from neuroimaging studies in MDD patients reveal altered activation patterns in lateral prefrontal brain areas. Successful cognitive behavioral therapy (CBT) is associated with a recovery of these neural alterations. Moreover, it has been demonstrated that transcranial direct current stimulation (tDCS) is capable of influencing prefrontal cortex activity and cognitive functions such as working memory and emotion regulation...
