Poor sleep quality and duration are markers of prodromal parkinsonism and Parkinson’s disease

Takeaway

  • In the general population, those with poorer sleep quality and shorter sleep duration have a higher chance of developing parkinsonism and an even higher risk of being diagnosed with Parkinson’s disease (PD).

Why this matters

  • The progressive worsening of sleep quality and duration over the 2 years prior to a diagnosis of parkinsonism, especially PD, suggests that these sleep parameters are markers of the prodromal phase of parkinsonism.
