PD patients with RBD showed higher Non-Motor Symptoms Scale (NMSS) score, higher Hamilton Depression Rating Scale (HAMD) score, higher Hamilton Anxiety Rating Scale (HAMA) score, higher Fatigue Severity Scale (FSS) score, higher PD Sleep Scale 2nd version (PDSS-2) score, lower Montreal Cognitive Assessment (MOCA) score and higher scores for the cognitions and communication domains from the PD Questionnaire-39 (PDQ-39).
In addition to the genotypes of rs671, the patients were assessed with the PD sleep scale-2nd version (PDSS-2) and the Epworth sleepiness scale (ESS) for symptoms of daytime and nocturnal sleep disturbances.
We examined the correlations between the Parkinson disease sleep scale-2 (PDSS-2) scores and different variables, namely the Unified Parkinson Disease Rating Scale, Parkinson disease questionnaire, Beck Depression Inventory, and Beck Anxiety Inventory (BAI).
Each patient completed the Thai version of the Epworth Sleepiness Scale (ESS) questionnaire to evaluate excessive daytime sleepiness (EDS), and the PD Sleep Scale version-2 (PDSS-2) questionnaire to evaluate night-time sleep disturbance.
The results of the Parkinson's Disease Sleep Scale 2nd version (PDSS-2) were heterogeneous, and those on the Snaith-Hamilton Pleasure Scale (SHAPS) were not statistically significant (P = .61).
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.
Co-primary outcome measures were the changes between baseline and end of the treatment period in sleep maintenance/efficiency as assessed by polysomnography and the Parkinson's Disease Sleep Scale Version 2 (PDSS-2) score.
HPDC treatment led to improvement of all applied motor (UPDRS III, AIMS) and non-motor (BDI-II, MoCA, PDNMS, PDSS-2, King's PD Pain Scale, QUIP, PDQ-39) scores (p < 0.05) indicating benefits for akinesia, tremor, dyskinesia, cognition, sleep, pain, impulse control disorders and quality of life.
To assess insomnia, the Pittsburgh Sleep Quality Index, a generic scale, and three disease-specific scales: the Parkinson Disease Sleep Scale (PDSS), the PDSS-2, and Scales for outcomes in Parkinson's disease (PD)-Sleep-Nocturnal Sleep subscale are discussed.
