How is tDCS administered?

It is a short, painless procedure. While you rest in a comfortable chair or exam table, two 2x2 or 2x4 inch electrodes are placed on your scalp with wires attached.

A constant-current electrical stimulator with about as much voltage as a 9-volt battery is applied for approximately 20 minutes. A slight itching sensation is sometimes felt breifly in the scalp.

The stimulation will be repeated for several consecutive days or sometimes up to several weeks depending on patient response.
