NIMH Rhythms and Blues Study: A Prospective Natural History Study of Motor Activity, Mood States, and Bipolar Disorder

Description

Background: Mood disorders, such as bipolar disorder, can have serious effects on a person s life. People with bipolar disorder are more likely to have heart disease and abuse substances. In this natural history study, researchers would like to learn more about the connection between exercise and mental health in people with and without mood disorders. Objective: To better understand relationships among physical activity, sleep, and mental health. Eligibility: People aged 12 to 60 years with a history of a mood disorder. Healthy spouses and relatives with no mood disorders are also needed. Design: Participants will be in the study up to 2 years. For up to 20 days in a row, at 4 times during the study, participants will: Complete an electronic diary on their smartphone. Participants will answer questions about their mood, health, sleep, and daily activities. Wear an activity monitor, like a wristwatch, that records how much they move. Wear a light sensor, as a necklace, to record the amount of light in their environment. Some participants will do additional tests. Twice during the study, for 3 days in a row, they will: Wear monitors to record their temperature, heart rate, and sleep. Provide saliva samples. Complete cognitive tasks on their smartphone. Participants will visit the NIH clinic 2 times. They will have a physical exam, with blood and urine tests. They will wear a heart monitor. They will ride a stationary bike for 30 minutes. They may have an imaging scan. Some participants will stay overnight. They will go to sleep wearing a cap to measure their brain activity.
