Many studies have sought to describe the relationship between sleep disturbance and cognition in Parkinson's disease (PD). The Parkinson's Disease Sleep Scale (PDSS) and its variants (the Parkinson's disease Sleep Scale-Revised; PDSS-R, and the Parkinson's Disease Sleep Scale-2; PDSS-2) quantify a range of symptoms impacting sleep in only 15 items. However, data from these scales may be problematic as included items have considerable conceptual breadth, and there may be overlap in the constructs assessed.

- Sleep disorders have notable neuropsychological effects, but research on their impact on cognition in Parkinson’s disease (PD) shows inconsistent results.
- A review and meta-analysis of 16 studies revealed that poor sleep significantly influences global cognitive function and specific memory and executive functions.
- Methodological issues in existing studies highlight the need for further research to clarify the mechanisms by which disturbed sleep affects cognition in PD, which is crucial for clinical practices.
