What is tDCS?

Transcranial direct current stimulation (tDCS) is a non-invasive, non-pharmacological and painless form of brain stimulation. It’s used to treat depression and chronic pain in the EU and the UK. tDCS delivers a weak direct current (0,5-2 mA) to specific brain areas via electrodes placed on the scalp, which helps the cortex of the brain become more easily excited. In depression treatment, the electrodes are placed on the forehead to target the dorsolateral prefrontal cortex (DLPFC). Side effects are less severe than those from antidepressants and include mild stinging sensations under the electrodes and mild headaches that pass after 30 minutes.
