Summary

Sleep disturbances like insomnia and nightmares are significantly more common in Indian Parkinson's disease (PD) patients than in healthy individuals. These sleep issues often correlate with the severity of PD symptoms and medication dosage.

Area of Science:

  • Neurology
  • Sleep Medicine
  • Epidemiology

Background:

  • Parkinson's disease (PD) is a neurodegenerative disorder affecting motor function.
  • Sleep disturbances are frequently reported in PD patients but require further characterization in specific populations.
  • Understanding sleep issues in Indian PD patients is crucial for comprehensive care.

Purpose of the Study:

  • To determine the prevalence and types of sleep disturbances in Indian Parkinson's disease patients.
  • To compare sleep problems in PD patients with age-matched healthy controls.
  • To identify factors associated with sleep disturbances in PD.

Main Methods:

  • A cohort of 149 Indian Parkinson's disease patients and 115 healthy controls were assessed.
  • A validated 23-question sleep questionnaire was administered for sleep assessment.

  • Clinical evaluation included Hoehn and Yahr score and Unified Parkinson's Disease Rating Scale (UPDRS).

    • Main Results:

    • 42% of PD patients reported sleep problems versus 12% of controls (P < 0.001).
    • Insomnia (32%), nightmares (32%), and excessive daytime sleepiness (15%) were common in PD patients.
    • Nightmares and daytime sleepiness were associated with higher disease severity (Hoehn and Yahr, UPDRS) and levodopa dosage.

    Conclusions:

    • Sleep disturbances are highly prevalent in Indian Parkinson's disease patients.
    • Sleep problems significantly correlate with PD severity and medication.
    • Addressing sleep disturbances is essential for improving the quality of life for PD patients.
