Transcranial direct current stimulation efficacy in trigeminal neuralgia.

ABSTRACT

Trigeminal neuralgia is a severe, disabling pain and its deafferentation remains a challenge for health providers. Transcranial direct current stimulation is a non-invasive stimulation technique which finds new utility in managing pain. Therefore, the introduction of alternative, non-invasive, safe, and effective methods should be considered in treating patients with trigeminal neuralgia unresponsive to conventional treatment.
