Transcranial Direct Current Stimulation for Depression

Summary

Several studies have shown that tDCS is valuable and safe options to improve depressive symptoms in adult patients . However, regarding the tDCS to treat depression in elderly population, only few studies have been reported, and there is no consensus among them. To our knowledge, prefrontal cortex tDCS could be reasonably safe and efficient options for the treatment of several psychiatric illnesses in a population presenting resistance to and/or intolerance of pharmacotherapy . Moreover, the safety tolerability profile of tDCS is a strong argument in favour of exploring their use in the depressed population. Therefore, current study will investigate the efficacy and safety of prefrontal tDCS used as additive treatment in patients with LLD.
