Clinical Trial Summary

Transcranial Direct Current Stimulation (tDCS), is a neuromodulatory technique, that is safe, well-tolerated, easy to administer and fairly inexpensive. Results from tDCS trials involving participants with several neuropsychiatric disorders, including major depression, bipolar disorder, schizophrenia and substance use disorder are encouraging. The clinical effects of tDCS are broad; the underlying condition, the areas stimulated together with the type and duration of stimulation are important factors. In patients with neuropsychiatric conditions, a reduction of symptoms, an enhancement of neurocognitive functions together with an overall improvement in functionality and wellbeing have been consistently reported. These effects emerge during the stimulation period, in the weeks after stimulation, the effects seem to peak and consolidate further. tDCS appears to enhance the effects of other interventions as well; however, to date, there have been no studies into the effects of using tDCS as an add-on intervention to psychotherapy on symptoms and wellbeing
