Background: Sleep disturbances are among the most common and severe symptoms reported by people with primary brain tumors (PBT). Smart wearable devices like Fitbits may be able to give detailed data about people s sleep and circadian rhythms. In this study, researchers will use Fitbits to learn more about sleep disruptions caused by tumors. This might help them design better future treatment and supportive care studies. Objective: To describe sleep disturbances and circadian disruption in people with PBT. Eligibility: English-speaking adults ages 18 and older who have PBT and are enrolled in the NIH study, Evaluation of the Natural History of and Specimen Banking for Patients with Tumors of the Central Nervous System. It is also known as the Natural History Study, trial #16C0151. Design: Participants will be screened over the telephone or in person. They will be asked about their medical history. Their cancer diagnosis will be confirmed through test results and pathology reports. Participants will complete 4 surveys. The surveys take about 20 minutes to complete and will ask about: The quality of their sleep Their ability to fall asleep and stay asleep How the quality of their sleep affects their daily activities Their sleep hygiene and preferences Participants will get a Fitbit. It looks like a watch and is worn on the wrist. They will connect the device to their smart phone to track sleep, heart rate, and activity. They will wear it for 1 month. Participants will keep a daily sleep diary for 1 week. It will be sent via an electronic link. They will also repeat 2 of the surveys. Participation will last for 1 month.
