Sleep parasomnias and the odds of Parkinson’s disease in men


  • Probable sleep parasomnias were associated with higher odds of Parkinson’s disease (PD) in men.

Why this matters

  • Research suggests that sleepwalking (SW), a non-rapid eye movement (REM) sleep behavior disorder (RBD), is highly prevalent in patients with PD (10% versus 1.0%–2.3% in the general population) and that the presence of non-REM parasomnias in this patient population is associated with worse symptoms, cognitive impairment, and depression.

  • This is the first population study (according to the authors) that examined the association of SW with PD in comparison with a general population as a reference group.
