Subjective and objective assessment of daytime sleepiness in advanced Parkinson’s disease


  • In those with Parkinson’s disease (PD), excessive daytime sleepiness (EDS) was detectable in 69% of study participants, yet only 43% of participants subjectively reported EDS.

Why this matters

  • Misperception of subjectively reported sleepiness in PD highlights the need for objective assessments to determine appropriate sleepiness management plans for PD.
