A low-carbohydrate, ketogenic diet (LCKD) may improve narcolepsy symptoms. Nine patients showed reduced symptom scores and daytime sleepiness after 8 weeks on the Atkins diet plan.

Area of Science:

  • Neurology
  • Dietary Science
  • Sleep Medicine

Background:

  • Narcolepsy is a chronic neurological disorder affecting sleep-wake cycles.
  • Daytime sleepiness and other symptoms significantly impair quality of life.
  • Current treatments offer incomplete symptom management.

Purpose of the Study:

  • To investigate the effects of a low-carbohydrate, ketogenic diet (LCKD) on narcolepsy symptoms.
  • To assess changes in daytime sleepiness and overall symptom severity.

Main Methods:

  • Nine patients diagnosed with narcolepsy participated in the study.
  • Participants followed the Atkins diet plan, a type of LCKD, for 8 weeks.
  • The Narcolepsy Symptom Status Questionnaire (NSSQ) was used for symptom assessment.

Main Results:

  • The total NSSQ score decreased by 18% over the 8-week study period (from 161.9 to 133.5, p = 0.0019).
  • Patients reported modest improvements in daytime sleepiness.
  • The LCKD intervention was associated with reduced overall symptom burden.

Conclusions:

  • A low-carbohydrate, ketogenic diet may offer a beneficial dietary intervention for managing narcolepsy symptoms.
  • LCKD shows potential for improving daytime sleepiness in individuals with narcolepsy.
  • Further research is warranted to confirm these findings and explore mechanisms.
