Abstract
Trigeminal neuralgia (TN) is a condition characterized by paroxysmal excruciating and usually unilateral pain attacks within the territory of one or more divisions of the trigeminal nerve. The underlying pathophysiological mechanisms remain poorly understood. The abrupt onset and termination of electric shock-like severe pain, the triggering role of non-noxious light sensory stimuli, the spreading of pain beyond the stimulated area, and the post-attack refractoriness represent some of the intriguing and challenging aspects of TN pathophysiology. This chapter reviews the updated pathophysiological hypotheses for TN, the emerging role of ion channels potentially representing novel therapeutic targets for the treatment of the disorder, and the current therapeutic approach based on a diagnostic work-up and treatment algorithm.
