Evaluation and Management of Excessive Daytime Sleepiness in Adolescents

Introduction to Excessive Daytime Sleepiness

The American Academy of Sleep Medicine recommends that excessive daytime sleepiness be evaluated for underlying causes, including medication-induced sleepiness, primary sleep disorders, and other medical conditions 1

Selective serotonin reuptake inhibitors (SSRIs), such as fluoxetine, can cause significant daytime sedation and are recognized as insomnia-contributing medications that derange restorative sleep, according to the American Academy of Sleep Medicine 1, 2
Consider switching fluoxetine administration to bedtime to convert the sedating side effect into a therapeutic sleep benefit, rather than causing daytime dysfunction, as suggested by the American Academy of Sleep Medicine 2

Obtain detailed information addressing specific elements that distinguish between sleep disorders, including cataplexy symptoms, sleep paralysis, hypnagogic hallucinations, automatic behaviors, nap characteristics, snoring or witnessed apneas, leg discomfort at night, and actual nocturnal sleep duration, as recommended by the American Geriatrics Society 3, 4

The Epworth Sleepiness Scale (ESS) is the most commonly used screening tool, with a score ≥10 indicating pathological sleepiness, according to the American Geriatrics Society 3, 4, 5
A sleep diary can be used to document actual sleep-wake patterns for 1-2 weeks, as recommended by the American Geriatrics Society 3, 4

If the ESS score is ≥10 and medication adjustment doesn't resolve symptoms, proceed with polysomnography (PSG) followed by multiple sleep latency testing (MSLT), as recommended by the American Geriatrics Society 3, 4, 5
PSG is required to exclude obstructive sleep apnea before diagnosing primary hypersomnia, according to the American Geriatrics Society 3, 4

Consider medication-induced sleepiness from fluoxetine as the most likely cause, followed by insufficient sleep syndrome, narcolepsy, idiopathic hypersomnia, obstructive sleep apnea, and depression-related hypersomnia, as recommended by the American Academy of Sleep Medicine 1, 2

Do not assume all sleepiness is depression-related without excluding primary sleep disorders, as warned by the American Academy of Sleep Medicine 2
Do not add sedating medications to treat presumed insomnia when the patient has excessive daytime sleepiness, as cautioned by the National Comprehensive Cancer Network 5, 2

Refer to a sleep specialist if the ESS score ≥10 persists after medication adjustment, or if there is clinical suspicion for narcolepsy, or if the cause of sleepiness remains unknown after initial workup, as recommended by the American Geriatrics Society and the American Academy of Sleep Medicine 3, 2
