Trigeminal Neuralgia: Current Understanding and Treatment Approaches

Trigeminal neuralgia (TN) is a debilitating chronic pain disorder characterized by sudden, severe, and episodic facial pain along the distribution of the trigeminal nerve. This article provides an overview of the current understanding of TN, including its epidemiology, etiology, pathophysiology, clinical presentation, and diagnostic criteria. Various treatment approaches for TN are discussed, ranging from conservative management with medications to invasive procedures such as neurosurgical interventions. The efficacy, risks, and limitations of each treatment modality are explored, along with emerging therapies and future directions in TN research.
