Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The objective of this study is to test the feasibility and physiological effect of low-frequency (1 Hz) acoustic stimulation delivered during nocturnal NREM sleep in epilepsy patients. The long-term goal is to develop this protocol for daily, long-term use in a home setting, for nocturnal seizure and IED suppression

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

1. To test the feasibility of wearing an earphone system delivering acoustic stimulation during a night of sleep in adult epilepsy patients monitored in an inpatient unit.
2. To determine the acute physiological effects of low-frequency acoustic stimulation on interictal epileptiform discharge (IED) frequency during NREM sleep in adult patients with epilepsy in an ambulatory setting.
3. To determine the feasibility of applying low-frequency acoustic stimulation in a long-term home setting in adult epilepsy patients with frequent nocturnal seizures.
