This is a non-drug study including participants with NT1 and healthy participants using devices designed for at-home assessments. The study will assess whether a portable EEG device provides an EEG signal comparable to inpatient nPSG. The frequency and characteristics of wake and sleep patterns and transitions over multiple nights will also be characterized. Participants with NT1 who will complete the study TAK-994-1501 (NCT04096560) will be eligible to enter the current study following the appropriate washout period (60 days).~The study will enroll approximately 32 participants (16 participants with NT1 and 16 healthy participants). Participants will be enrolled in the 2 groups:~NT1 Participants~Healthy Participants~This multi-center trial will be conducted in the United States. The overall time to participate in this study is approximately 8 days. The follow-up visit will occur on Day 10 and during this debrief, participants will answer a questionnaire on user experience (device comfort) for the wearable devices.
The purpose of this study is to determine whether portable devices can provide measurements at home similar to those taken in the clinic, in particular in participant with NT1, and to investigate night-to-night changes in sleep patterns using these devices at home. This study may enable future at-home studies and ultimately lead to a decreased burden on the people who need these measurements.
