Live Recordings (Sleep Medicine Trends 2026)-08 Complex Hypersomnia Cases

Video Transcription

Video Summary

The speaker presents a case-based approach to managing hypersomnia disorders, focusing on (1) comorbidities, (2) pregnancy/breastfeeding, and (3) optimizing treatment when patients do poorly.<br /><br />Case 1: A 31-year-old woman diagnosed with narcolepsy type 2 meets criteria clinically and on MSLT (short sleep latency and multiple SOREMPs). The talk highlights how depression and ADHD commonly co-occur with narcolepsy/IH and can complicate diagnostic certainty. Antidepressants may worsen sleepiness (duloxetine is notably sedating) and can distort PSG/MSLT results by REM suppression or, if stopped too briefly, REM rebound. Medication choice should consider comorbidities, contraindications, and drug interactions—especially CYP3A4 induction reducing hormonal contraceptive efficacy, QT prolongation (e.g., pitolisant plus QT-prolonging antidepressants), CYP2D6 interactions, and oxybate-related sedation risks.<br /><br />Case 2: A 25-year-old woman with idiopathic hypersomnia on modafinil wants pregnancy counseling. The speaker advocates balancing risks of medication exposure against risks of untreated disease (driving, employment). Modafinil/armodafinil are discouraged due to increased congenital malformation risk; methylphenidate has more reassuring (though not risk-free) data. Strategies while trying to conceive include limiting use to non-pregnant cycle windows. Lactation data are limited; oxybates may be feasible with timed breastfeeding due to short half-life.<br /><br />Case 3: A 36-year-old man reports stimulants “don’t work,” but the issue is severe sleep inertia preventing morning dosing. Management targets sleep inertia using oxybates, bedtime long-acting bupropion, delayed-release methylphenidate, circadian phase strategies, or pre-awakening “alarm-pill” dosing. The Q&A notes oxybate selection often hinges more on once- vs twice-nightly dosing than sodium in healthy patients, though sodium counseling is required. Registries are emphasized to improve pregnancy safety data.
