What is the difference between tDCS and TMS?

TMS (Transcranial Magnetic Stimulation) is the process of passing large magnets near a person’s scalp in order to generate a magnetic field that stimulates nerve-cells in the brain. Similarly tDCS (Transcranial Direct Current Stimulation) uses low levels of electric current to energize neurons. However, tDCS is applied directly to the scalp and therefore can often produce more direct, stronger, and longer lasting effects.

TMS requires large machines, often occupying an entire room, and requires a patient to be physically still during the treatment period. Alternatively, tDCS devices are often compact, hand-held units that can be carried anywhere. The person using tDCS is not required to sit still, and depending on the case may even be able to complete their stimulation in the comfort of their own home.
