Lunar phases and seizure occurrence: Just an ancient legend?

Abstract

The authors retrospectively reviewed all neurologic records of an emergency unit from 1999 to 2003 to identify a potential association between lunar phases and seizure occurrence. Overall 859 patients admitted for seizure occurrence were divided into the four quarters of the synodic month according to moon phases. A significant clustering of seizures around the full moon period was observed, supporting the ancient belief of periodic increased seizure frequency during full-moon days.
