Transcranial direct current stimulation, tDCS, is a promising treatment for conditions such as depression and addictive disorders. New evidence on the safety of transcranial direct current stimulation was recently offered by a new study showing that tDCS does not affect metabolism.
Transcranial direct current stimulation is a non-invasive method for modulating neuronal activity by introducing a small electric current into the brain via electrodes placed on the scalp.
“In earlier studies, transcranial direct current stimulation has been found to alter glucose metabolism and stress hormone levels, among other things. However, our study looked at more than 100 molecules and we didn’t observe an effect on any of them,” PhD student Aaron Kortteenniemi, the lead author of the study, from the University of Eastern Finland notes.
