About
This is an observational study evaluating patients diagnosed with narcolepsy or idiopathic hypersomnia that have been prescribed a new/different hypersomnia treatment. The study is being done to better understand how hypersomnia treatment(s) impact blood pressure and cognitive function.
Full description
This is an observational study evaluating how hypersomnia medications influence blood pressure and cognitive function in patients diagnosed with narcolepsy or idiopathic hypersomnia. Blood pressure will be assessed using 24-hour ambulatory blood pressure monitoring equipment. Cognitive function will be evaluated using the Oculo-Cognitive Addition Test (OCAT). Both tests will performed at baseline (e.g., before starting a new hypersomnia medication) and after taking a stable dose of the new hypersomnia medication for at least three months. All medications will be prescribed by a clinical sleep specialist as part of routine medical care and covered by subject's health insurance plan (i.e., no medications are dispensed/titrated/paid for by the study investigators/trial).
The 24-hour ambulatory blood pressure test will be setup in person by staff. During the blood pressure test, the study participant will also complete a sleep diary and wear an actigraphy watch to track activity and sleep-wake cycle. The 24-hour ambulatory blood pressure test will be programmed to inflate a blood pressure cuff placed around the arm every 15 - 30 minutes.
The OCAT test, which takes approximately 15-20 minutes to complete, will be completed in person as well.
Each study participant may complete one or both tests. Each study participant may complete more than two assessments (e.g., patient that has been prescribed a second hypersomnia medication). If a patient presents already taking a medication of interest at baseline for at least the last 3 months then the participant may undergo baseline assessment(s) while taking respective medication(s).
