Evaluating the significance of abnormal EEG from sleep studies

Children with abnormal EEG findings during a sleep study have a high risk of developing subsequent seizures, according to new study findings.

Polysomnography is commonly used to evaluate sleep disorders such as sleep-disordered breathing and night-time episodes, in children with or without neurological comorbidities. It includes limited use of EEG to stage sleep.

To investigate whether abnormal EEG during polysomnography is associated with the future development of seizures, researchers from St Christopher’s Hospital for Children and the Drexel University College of Medicine, in Philadelphia, Pennsylvania, USA, performed a retrospective chart review.
