Read the first 6 ABPN Sleep Medicine and Neurological Disorders flashcards as text

  1. A 55-year-old with a history of alcohol use disorder presents with ophthalmoplegia, ataxia, and confusion. What is the MOST likely diagnosis and its cause?

    Answer: Wernicke encephalopathy due to thiamine (B1) deficiency

    Wernicke encephalopathy is caused by thiamine deficiency, classically presenting with the triad of ophthalmoplegia, ataxia, and confusion in the setting of alcohol use disorder.

  2. Which sleep stage is characterized by high-amplitude, slow (< 2 Hz) delta waves on EEG and is considered essential for physical restoration?

    Answer: Stage N3 (slow-wave/deep NREM)

    Stage N3 slow-wave sleep is characterized by delta waves and is associated with physical restoration, growth hormone release, and memory consolidation.

  3. Obstructive sleep apnea is MOST strongly associated with which neuropsychiatric condition?

    Answer: Depression and cognitive impairment

    OSA is strongly associated with depression, cognitive impairment, and executive dysfunction due to intermittent hypoxemia and sleep fragmentation.

  4. Which term describes a sleep disorder characterized by confusional arousals, sleepwalking, and sleep terrors arising from NREM slow-wave sleep?

    Answer: NREM parasomnias (disorders of arousal)

    NREM parasomnias (disorders of arousal) include sleepwalking, sleep terrors, and confusional arousals, all arising from incomplete awakening from deep NREM sleep.

  5. A patient with delayed sleep phase disorder characteristically shows what sleep pattern?

    Answer: Falls asleep and wakes up much later than desired but sleeps a normal duration

    Delayed sleep phase disorder involves a delayed circadian rhythm, causing inability to fall asleep until very late at night and difficulty waking in the morning.

  6. Which neurotransmitter/hormone is MOST involved in regulating the sleep-wake circadian rhythm and is secreted by the pineal gland?

    Answer: Melatonin

    Melatonin, secreted by the pineal gland in response to darkness, entrains the circadian clock and promotes sleep onset; its secretion is suppressed by light.
