Outcome Measures

Primary Outcomes (1)

  • Change in mean 24-hour ambulatory blood pressure

    Change in 24-hour ambulatory blood pressure from baseline (pre-treatment) to after taking a stable dose of medication for at least 3 months

    Baseline, at least 3 months

Secondary Outcomes (3)

  • Change in Oculo-Cognitive Addition Test (OCAT) completion time

    Baseline, at least 3 months

  • Change in mean daytime and nighttime 24-hour ambulatory blood pressure

    Baseline, at least 3 months

  • Change in 24-hour ambulatory blood pressure diurnal pattern (dipper versus non-dipper)

    Baseline, at least 3 months

Study Arms (3)

Narcolepsy Type 1

Study participant will complete test(s) before and after taking a stable dose of a new/different hypersomnia medication. All hypersomnia medications will be prescribed and titrated by a clinical sleep specialist outside of this protocol.

Diagnostic Test: 24-hour Ambulatory Blood Pressure MonitoringDiagnostic Test: Oculo-Cognitive Addition Test (OCAT)

Narcolepsy Type 2

Study participant will complete test(s) before and after taking a stable dose of a new/different hypersomnia medication. All hypersomnia medications will be prescribed and titrated by a clinical sleep specialist outside of this protocol.

Diagnostic Test: 24-hour Ambulatory Blood Pressure MonitoringDiagnostic Test: Oculo-Cognitive Addition Test (OCAT)

Idiopathic Hypersomnia

Study participant will complete test(s) before and after taking a stable dose of a new/different hypersomnia medication. All hypersomnia medications will be prescribed and titrated by a clinical sleep specialist outside of this protocol.

Diagnostic Test: 24-hour Ambulatory Blood Pressure MonitoringDiagnostic Test: Oculo-Cognitive Addition Test (OCAT)

Interventions

Arm blood pressure cuff that will automatically inflate every 15-30 minutes to check blood pressure while awake and asleep over 24 hours. Patient will also complete a sleep diary and wear an actigraphy watch during this test.

  • Subject must be willing to postpone starting medication until after completion of baseline assessment(s).
  • If subject has been taking a prescribed hypersomnia medication(s) at a stable dose for at least 3 months and has been prescribed a new medication, then subject may complete baseline assessment(s) while taking initial hypersomnia medication(s) before starting new medication.
