Abstract Paulinia cupana (guarana) is a Brazilian plant given great prestige in popular medicine, for example as being a potent stimulator of brain functions. The authors assessed the effects of the long-term administration of guarana on the cognition of normal, elderly volunteers. Forty-five volunteers were studied, with a random distribution in three experimental groups: placebo (n=15), caffeine (n=15), and guarana (n=15), in a double-blind study. There were no significant cognitive alterations in these volunteers.

A Paulínia cupana (o guaraná) é uma planta da flora brasileira que goza de grande prestígio na medicina popular, entre eles de ser potente estimulante das funções cerebrais. Os autores avaliaram os efeitos da administração crônica da guaraná sobre a cognição de voluntários idosos normais. Foram estudados 45 voluntários, sendo distribuídos aleatoriamente para um dos três grupos experimentais. Placebo (n=15), Cafeína (n=15) e Guaraná (n=15), em estado duplo-cego. Não obteve-se nenhuma mudança significativa na cognição desses voluntários.
