BACKGROUND Preliminary evidence suggests transcranial direct current stimulation (tDCS) has antidepressant efficacy. AIMS To further investigate the efficacy of tDCS in a double-blind, sham-controlled trial (registered at www.clinicaltrials.gov: NCT00763230). METHOD Sixty-four participants with current depression received active or sham anodal tDCS to(More)
Two recent sham-controlled studies found that transcranial direct current stimulation (tDCS) was an effective treatment for depression. As tDCS is painless, relatively safe and inexpensive, its efficacy in treating depression warrants further investigation. This double-blind, randomized study tested tDCS at the same stimulation parameters as a previous(More)
BACKGROUND Several recent trials have reported transcranial direct current stimulation (tDCS) to be effective in treating depression, though the relative benefits of different electrode montages remain unexplored. Whereas all recent studies have used a bifrontal (BF) electrode montage, studies published in the 1960s and 1970s placed one electrode in an(More)
BACKGROUND Typically, transcranial direct current stimulation (tDCS) treatments for depression have used bifrontal montages with anodal (excitatory) stimulation targeting the left dorsolateral prefrontal cortex (DLPFC). There is limited research examining the effects of alternative electrode montages. OBJECTIVE/HYPOTHESIS This pilot study aimed to examine(More)
Computer-administered cognitive training (CT) tasks are a common component of cognitive remediation treatments. There is growing evidence that transcranial direct current stimulation (tDCS), when given during cognitive tasks, improves performance. This randomized, controlled trial explored the potential synergistic effects of CT combined with tDCS in(More)
The capacity for transcranial direct current stimulation (tDCS) to increase learning and cognition shows promise for the development of enhanced therapeutic interventions. One potential application is the combination of tDCS with cognitive training (CT), a psychological intervention which aims to improve targeted cognitive abilities. We have previously(More)
The effects of the divalent cations Ca2+, Sr2+, Ba2+, Mg2+, Mn2+, and Cd2+ were studied on gamma-aminobutyric acidA (GABAA) responses in rat cerebral cortical synaptoneurosomes. The divalent cations produced bidirectional modulation of muscimol-induced 36Cl- uptake consistent with their ability to permeate and block Ca2+ channels. The order of potency for(More)
BACKGROUND There is growing evidence that transcranial direct current stimulation (tDCS) may be an effective treatment for depression. However, no study to date has profiled the antidepressant effects of tDCS using items or factors on depression symptom severity rating scales. This could potentially provide information about the mechanisms by which tDCS(More)
OBJECTIVES To report a case of hypomania induced by transcranial direct current stimulation (tDCS) given with an extracephalic reference electrode. Transcranial direct current stimulation is a noninvasive brain stimulation technique in which a weak current is applied through the scalp to produce changes in neuronal excitability in the underlying cerebral(More)
OBJECTIVES This study aimed to examine a bitemporal (BT) transcranial direct current stimulation (tDCS) electrode montage for the treatment of depression through a clinical pilot study and computational modeling. The safety of repeated courses of stimulation was also examined. METHODS Four participants with depression who had previously received multiple(More)
