Some sleep physicians are employing a new tool to help design the most effective CBT-I intervention for insomnia patients: patient-applied overnight EEG/EOG/EMG devices (“overnight EEG”), which measure indices such as brain waves, eye movements, and muscle movements. Though this at-home objective data gathering may sound similar to the ubiquitous home sleep apnea test, the overnight EEG is not intended and does not screen for sleep-disordered breathing. Clinicians are employing it with insomnia patients to gain insights into their sleep architecture and patterns.

Robert S. Rosenberg, DO, FCCP, utilizes one such device, Sleep Profiler by Advanced Brain Monitoring, in his practice. Rosenberg is the medical director of the Sleep Disorders Center of Prescott Valley, Ariz, and sleep medicine consultant for Mountain Heart Health Services in Flagstaff. While studying the work of the Penn State Cohort group, he became interested in the high rate of misperception among patients with insomnia. “The researchers were advocating strongly for objective measures such as PSG in evaluating patients with insomnia,” he says. Because Sleep Profiler provides a total profile of types of sleep, including how many times per hour the patient has arousals and from what cause, Rosenberg decided to employ it as an objective measure.
