Dear colleagues,
I am new to the community here - I run a team who look at sleep and circadian rhythms as relates to health and wellbeing. We recently published an analysis of data in the Fox Insights study on self-reported sleep problems in PD: https://onlinelibrary.wiley.com/doi/10.1111/jsr.14453.
We report sleep problems are very highly prevalent (~85% of PD patients endorse poor sleep, twice the rate for matched controls), and sleep problems are linked with greater depression, more problems of independent living, poorer quality of life and more OFF periods. About 7% of respondents endorsed sleep as their most bothersome PD symptom, but our analysis leads us to suspect that these participants have less severe motor and other non-motor symptoms, and as such the relative ranking of their sleep complaints in higher. The nature of the sleep problems endorsed are most commonly of non-specific insomnia-type problems of sleep initiation and/or maintenance and excessive day time sleepiness, with less indications for sleep apnea (although these are all from self-report). Hopefully these findings may be of interest to the community,
