Frequently Asked Questions about tDCS
Mild current produced from the tDCS device primes the stimulated area for action without causing any neurons to fire electrical signals. Overall, this priming effect causes the neurons to become more likely to respond and communicate with other connected neurons within the stimulated area.
The time for tDCS treatments can vary between studies. The average length for treatment is thought to be around 20 minutes.
Side effects for tDCS are minimal. The most common side effects are tingling and itching at the stimulation site, and slight headaches during treatment.
More research is needed at this point for further investigation in order to evaluate the potential risks of tDCS.
