National Medical Journal of India. 2012 Jan-Feb; 25(1): 21.http://imsear.searo.who.int/handle/123456789/139253Gelastic syncope or laughter-induced syncope is a rare disease often misdiagnosed as narcolepsy or cataplexy. We report a 54-year-old man with syncopal episodes. Each episode started after laughter, leading to light-headedness with blurring of vision and loss of consciousness for a few seconds. The episodes resolved spontaneously. The treatment of gelastic syncope is the same as that for neurally mediated syncope.enHumansLaughterMaleMedical History TakingMiddle AgedPolysomnographySyncope --classificationSyncope --diagnosisArticle
