Coexistence of TACS and trigeminal neuralgia: pathophysiological conjectures.

BACKGROUND

Trigeminal autonomic cephalgias (TACs) and trigeminal neuralgia are short-lasting unilateral primary headaches whose study is providing insights into craniofacial pain mechanisms. We report on 2 patients in whom trigeminal neuralgia coexists with the TACs paroxysmal hemicrania and SUNCT.

CONCLUSION

Coexistence of trigeminal neuralgia with various TAC forms suggests a pathophysiological relationship between these short-lasting unilateral headaches.
