In response: Effects of epilepsy treatments on sleep architecture and daytime sleepiness: An evidence‐based review of objective sleep metrics

We thank the authors for clarifying their study. Table 1 listed the study method accurately as ambulatory polysomnography. Currently, standard polysomnography remains the best test for clinical diagnosis. Although portable devices are approved, the American Academy of Sleep Medicine (AASM) guidelines suggest their use for diagnosis and monitoring response to non–continuous positive airway pressure (CPAP) treatments for obstructive sleep apnea (OSA).1 We agree with the authors that for research purposes, standard methodologies need to be established. The authors have no conflict of interest to declare in relation to this letter. We confirm that we have read the Journal's position on issues involved in ethical publication and affirm that this report is consistent with those guidelines
