Abstract
Plain Language Summary A suicidal patient with Short‐lasting Unilateral Neuralgiform headache attacks with Conjunctival injection and Tearing (SUNCT) whose excruciating condition did not respond to various treatments discovered that ayahuasca, a psychoactive concoction used by indigenous populations of South America, caused his attacks to cease entirely. Inhaled N , N ‐dimethyltryptamine (DMT), the principal psychoactive component of ayahuasca, also caused symptoms to disappear temporarily, as did a strong dose of lysergic acid diethylamide (LSD). This case study supports the potential of serotonergic psychedelics for the treatment of SUNCT and related headache disorders.
