Human behavior
Two studies found evidence that those with mental disorders i.e Schizophrenia generally exhibit 1.8% of increased violent or aggressive episodes during the full Moon,[22][23] but a more recent study found no such correlation to that of normal human beings.[24] An analysis of mental-health data found a significant effect of Moon phases, but only on schizophrenic patients.[25] Such effects are not necessarily related directly to the appearance of the Moon. A study into epilepsy found a significant negative correlation between the mean number of seizures and the phase of the Moon, but this correlation disappeared when the local clarity of the night sky was controlled for, suggesting that it was the brightness of the night that influenced the occurrence of epileptic seizures with advanced photosensitive epilepsy.[26]
