A device for the transcutaneous electrical stimulation of the trigeminal nerve is provided. The device has an elongated symmetrical support with at least one electrode pair, and the support can be applied on a person's forehead in the supraorbital region to cover the afferent paths of the supratrochlear and supraorbital nerves of the ophthalmic branch of the trigeminal nerve. Each electrode pair contacts a self-adhesive conductive gel that at least partially covers one surface of the support for attaching the support to the forehead to be applied to two lateral zones with the exception of an insulating central zone. Each lateral zone has one electrode of the electrode pair, an electric circuit for supplying to the electrode pair electric pulses that have a predefined intensity, and a measurement means for measuring the intensity of the supplied pulses that is connected to the electric circuit.
