-many pt have apnea and insomnia = treat apnea first
Diagnostic testing for apnea
-polycomnography only if:
-significant cardiorespiratory disease
-potential resp muscle weakness due to neuro-musc condition
-sleep-related hypoventilation
-chronic opiod med use
-hx of stroke
-severe insomnia
Sleep apnea tx
-wt loss
-smoking cessation
-avoid alc and CNS depressants
-sleep on side
-CPAP (continuous positive airway pressure)
-excessive daytime sleepiness tx w modafnil or armodafnil (assess CPAP adherence first and possibility of RLS or PLMS)
Sleep apnea + insomnia tx
-tx apnea before insomnia
-in obese pt w insomnia, rule out apnea
Excessive daytime sleepiness (EDS) tx in sleep apnea
-modafnil or armodafnil
-reveiw CPCP adherence first and posibility of RLD or PLMS
DSM-5 Narcolepsy
-recurring episodes of irresistible need to sleep
-3x week
-past 3 months
Narcolepsy tetrad
-EDS in 100% of pt (more severe in type I (cataplexy or hypocretin deficiency)
-cataplexy: sudden loss of muscle tone triggered by emotion (75%)
-hallucinations 30-60%
-sleep paralysis 25-50%
-all four 10-33%
Narcolepsy tx
-tx cataplexy
- tx EDS
Tx of cataplexy in narcolepsy
-sodium oxybate: GHB, high sodium
-Xywav: ages 7+, tx idiopathichypersomnia in adults, lower sodium
-Lumryz: adults only, ER dose, once nightly, high sodium
Excessive Daytime Sleepiness (EDS) tx in narcolepsy

-if mod renal impairment: start 37.5mg inc to max 75mg after 7 days
-if severe renal impairment: starting and max dose is 37.5mg
solriamfetol renal dosing
