In the largest study of its kind, researchers at Melbourne University found that up to 80% of people with epilepsy have seizure cycles which follow a natural rhythm.  Of these, the majority have seizures which occur in a 24 hour, or circadian, cycle.  However some people in the study exhibited daily, weekly or longer cycles, and some, up to 66%, had a combination associated of  patterns associated with their seizures.This new study of over 1000 people provided robust evidence of seizure cycles which had been known to exist from previous studies which had been conducted in small groups or over short periods of time.  This study also showed that the patterns are patient-specific and more common than previously thought.If you would like to know more about this research, please use the link here:
