To investigate a possible relationship between seizure frequency and the lunar cycle, we reviewed the occurrence of seizures recorded in our epilepsy monitoring unit over a 3-year period. Analysis of the total number of seizures (epileptic plus nonepileptic) showed no significant association. A separate analysis revealed that for nonepileptic seizures, there was an increase at the full moon, and for epileptic seizures, an increase in the last quarter. We conclude that there is no "full moon" effect on seizures as a whole, although there is a possible effect on nonepileptic seizures.
