Summary
This narrative review examines how Parkinson's disease disrupts sleep architecture, triggers REM sleep behavior disorder, and alters melatonin signaling through neurodegeneration of circadian-relevant brain structures. For lighting designers and caregivers, these findings underscore the importance of tailored circadian lighting interventions to support melatonin rhythms and reduce sleep disturbances in Parkinson's patients.
Key Findings
- REM sleep behavior disorder (RBD) is identified as a prodromal marker of Parkinson's disease, often preceding motor symptoms by years, highlighting the early circadian/sleep disruption in neurodegeneration.
- Melatonin dysregulation is linked to dopaminergic and non-dopaminergic neurodegeneration in Parkinson's, suggesting melatonin-based or light-based interventions may have therapeutic relevance.
- Sleep disturbances affect up to 90% of Parkinson's disease patients, making circadian-supportive lighting a potentially high-impact non-pharmacological intervention in this population.
