|Condition or disease||Intervention/treatment||Phase|
|Epilepsy||Other: Acoustic 1Hz Stimulation Other: Sham Background Noise||Not Applicable|
- 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.
- 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.
- To determine the feasibility of applying low-frequency acoustic stimulation in a long-term home setting in adult epilepsy patients with frequent nocturnal seizures.

Experimental: Acoustic 1Hz Stimulation
1 Hz acoustic stimulation applied via headphones and downloadable phone application during sleep every night.
Other: Acoustic 1Hz Stimulation
1Hz acoustic pulses delivered during sleep via headphones
Sham Comparator: Sham Background Noise
Background noise applied via headphones and downloadable phone application during sleep every night.
Other: Sham Background Noise
Background Noise used as a control
No Intervention: Baseline Seizure Monitoring
No use of sound system; Patients record seizures in a diary.
- Successful System Training [ Time Frame: 72 hours ]Assessment of how well participants learn to use stimulation smart-phone application and headphones, defined as the percentage of subjects with correctly maintained earphones during the first four hours of nocturnal sleep in the first days of use.
- Interictal Discharge frequency [ Time Frame: 72 hours ]IED frequency during nighttime sleep as measured by a 72 hour ambulatory EEG
- System Adherence [ Time Frame: 2 months ]Percentage of nights during which patients were compliant with the acoustic stimulation device during two months of home use (1 month control acoustic condition, 1 month 1Hz stimulation) determined weekly by patient self-report
- System Use effect on Features of Sleep [ Time Frame: 72 hours ]Effect of system use on sleep features, including time spent in each stage of sleep, delta and spindle power and spatial distribution gather from EEG.
- Seizure Control [ Time Frame: 3 months ]Seizure frequency during control and treatment months gathered from seizure diary and IED frequency gathered from EEG (1 month baseline, 1 month sham stimulation, 1 month 1Hz stimulation).
