Narcolepsy, a sleep disorder causing daytime sleepiness and cataplexy, was diagnosed in nine family members. Modafinil treatment improved their symptoms, highlighting its therapeutic potential.

Area of Science:

  • Neurology
  • Sleep Medicine
  • Genetics

Background:

  • Narcolepsy is a chronic neurological disorder characterized by excessive daytime sleepiness.
  • Key symptoms include cataplexy, sleep paralysis, and hypnagogic hallucinations.
  • Genetic factors may play a significant role in narcolepsy development.

Purpose of the Study:

  • To investigate narcolepsy in a multi-generational family with a history of excessive daytime sleepiness.
  • To diagnose narcolepsy and evaluate associated symptoms like cataplexy.
  • To assess the efficacy of modafinil in treating narcolepsy patients.

Main Methods:

  • Clinical evaluation of eleven patients with suspected narcolepsy.
  • Diagnostic tools included brain MRI, blood tests, EEG, polysomnography, and hypocretin CSF levels.

  • Patient sleepiness was assessed using Epworth and Stanford Sleepiness Scales.

    • Main Results:

    • Narcolepsy was diagnosed in nine out of eleven patients.
    • The diagnosed patients experienced excessive daytime sleepiness, sleep attacks, cataplexy, sleep paralysis, and hallucinations.
    • Modafinil treatment led to clinical improvement in the affected individuals.

    Conclusions:

    • Narcolepsy can manifest in familial clusters, suggesting a genetic predisposition.
    • Comprehensive diagnostic methods are crucial for accurate narcolepsy diagnosis.
    • Modafinil is an effective treatment option for managing narcolepsy symptoms.
