Brief Summary
This study is a within subject's assessment of whether a novel wearable technology, NextSense electroencephalography earbuds (EEGBuds), is able to detect differences in onset to sleep from wake versus in-laboratory, gold-standard electroencephalography (EEG) utilized as part of a standard four trial Maintenance of Wakefulness Test (MWT) at medicated baseline versus free of prescribed medications for promoting wake (random order).

Outcome Measures
Primary Outcomes (1)
Change in sleep onset latency
Sleep onset latency is the time in minutes it takes to transition from wakefulness to sleep. Within-individual change in the mean onset to sleep will be assessed from the two MWT sessions performed as detected by NextSense EEGBuds.
Study visits 1 and 2 (up to 16 days)
Secondary Outcomes (1)
Intraclass correlation between measurement methods
Up to 16 days
Study Arms (2)
Prescribed medication followed by drug holiday
EXPERIMENTALParticipants will complete the study assessments on a day when they take their prescribed medication(s) to promote wakefulness and then will repeat the study assessments on a day when they do not take the medication.
Drug holiday followed by prescribed medication
EXPERIMENTALParticipants will complete the study assessments on a day when they do not take their prescribed medication(s) to promote wakefulness and then will repeat the study assessments on a day when they take their medication as prescribed.
Interventions
Each NextSense EEGBud device comes with a universal-fit and/or custom-fit earmold with biometric sensors to detect the EEG, motion (via tri-axial accelerometers), and heart rate. A unique custom mold is created employing a 3D printer to capture the geometry of a patients' ear and external auditory canal with a ring laser scanner to an accuracy of within 0.1 mm. This design process allows for a custom fit, and therefore both comfort and complete, consistent contact with the inner surface of the ear canal, providing high quality signal capture of brain activity, and head and eye movements. In addition to the custom fit earmold, universal fit earmolds are available as well. The universal fit earmolds were designed also to allow for comfort and consistent contact with the inner surface of the ear canal to provide high quality signal capture of brain activity, and head and eye movements.
Ellcie Healthy glasses frames are embedded with multi-modal sensors for measuring eye movements, head movement, and ECG.
Participants will not take their prescribed wakefulness promoting medication(s) for one day to complete the study assessments. Medications typically used to promote wakefulness include amphetamine salts (Adderall), armodafinil (Nuvigil), clarithromycin (Biaxin), flumazenil, methylphenidate (Ritalin), and modafinil (Provigil).
Eligibility Criteria
You may qualify if:
- Adults ages 18-60 years of age previously diagnosed with narcolepsy type I (NT1), narcolepsy type 2 (NT2), or idiopathic hypersomnia (IH).
- Requiring daily wake promoting medication(s) continuously for 3 months for diagnosed NT1, NT2 or IH with symptomatic improvement on treatment documented by standard subjective or objective tools.
You may not qualify if:
- Presence of a diagnosed or suspected co-morbid sleep-related breathing disorder, parasomnia, or other sleep-related movement disorder.
- Unstable psychiatric disorder (e.g., acute psychosis, acute suicidal ideation or major depressive episode, active substance abuse/dependence).
- History of malignancy (active or in remission for \< 2 years) or active infectious disease at time of screening.
- Inability to safely tolerate wearing earbuds due to recent injury, skin breakdown, or infection.
- Uncorrected near visual acuity no worse than 20/50.
- Any other condition which may affect the outcome of this study or safety of the participant as determined by the principal investigator.
