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)
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)
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)
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 Evidence from recent clinical trials suggests that transcranial direct current stimulation (tDCS) may have potential in treating neuropsychiatric disorders. However, the optimal frequency at which tDCS sessions should be administered is unknown. OBJECTIVE/HYPOTHESIS This study investigated the effects of daily or second daily tDCS sessions on(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)
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)
Cognitive side-effects from electroconvulsive therapy (ECT) can be distressing for patients and early detection may have an important role in guiding treatment decisions over the ECT course. This prospective study examined the utility of an early cognitive screening battery for predicting cognitive side-effects which develop later in the ECT course. The(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)
Interest is rapidly developing in transcranial direct current stimulation (tDCS) as an emerging tool in neurology and psychiatry. tDCS involves the application of weak, unidirectional currents through scalp electrodes to alter neuronal excitability, that may outlast the period of stimulation (Arul-Anandam & Loo, 2009). In addition to being a tool for(More)
