Disease overview

NT1 is a less common variant of narcolepsy driven by deficiency/loss of hypocretin-producing neurons in the lateral hypothalamus [more].

Common symptoms

Patients with NT1 experience excessive daytime sleepinessat times including sudden attacks of drowsinesswith cataplexy (suddenextreme muscle weakness)sleep paralysisand hallucinations during sleep-wake transitions [ ].

WHEN TO SUSPECT

  • Recommendation 1

    NT1 can be diagnosed clinically (excessive daytime sleepiness plus documented cataplexy)

  • Recommendation 2

    sleep study testing demonstrating mean sleep latency <8 min or at least two sleep-onset REM periods during sleep latency testing or polysomnography are also indicative of the disease [more].

HOW TO TEST

  • Recommendation 1

    NT1 can be diagnosed clinically (excessive daytime sleepiness plus documented cataplexy)

  • Recommendation 2

    sleep study testing demonstrating mean sleep latency <8 min or at least two sleep-onset REM periods during sleep latency testing or polysomnography are also indicative of the disease [more].

TREATMENT

  • Recommendation 1

    Lifestyle modifications are recommended as first-line therapy, including scheduled napping, regular sleeping hours, diet assessment [more]. If symptoms are uncontrolled without medication, stimulants (particularly modafinil) are a first-line approach for daytime sleepiness

  • Recommendation 2

    sodium oxybate is approved for cataplexy [more].

PRIMARY CARE

  • Recommendation 1

    Patients should be counseled that lifestyle modifications generally must be continued to maintain symptom control [more]. Narcolepsy is associated with increased cardiovascular risk

  • Recommendation 2

    regular cardiovascular assessment and low threshold to treat is warranted [more]. Mood disorders including suicidal ideation is more common in patients with poor symptom control [more].

FURTHER SUPPORT

  • Recommendation 1

    Patients should be referred to a provider with experience in sleep disorders. Referral to Medical Genetics Department, if available. Initial virtual care is also available through organizations like TeleRare Health.

CLINICAL TRIALS

  • Recommendation 1

    Several trials are currently recruiting for Narcolepsy Type 1.
