Headache: Response to Lamotrigine.

A number of patients attending a psychiatry out patient department present with headache and cranial autonomic symptoms (CAS) which include cluster headache (CH), shortlasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) or cranial autonomic features (SUNA) and paroxismal hemicrania (PH). The present case reports describe two cases of SUNCT which showed response to lamotrigine. In a day-today practice SUNCT should be kept in mind as effective therapy is available.
