PrimaryDifference in objective EDSassessed after each intervention (day 15 of each intervention)Difference in objective excessive daytime sleepiness (EDS), measured with Multiple Sleep Latency Test (MSLT; minutes), in Parkinson patientsClinicalTrials.gov
PrimaryDifference in verbal episodic memory performanceassessed after each intervention (day 15 of each intervention)
Difference in verbal episodic memory performance, measured with the Hopkins Verbal Learning Test (HVLT; score ranges from 0 to 12, higher scores indicate better performance) delayed recall, in Mild Cognitive Impairment patients
ClinicalTrials.gov
SecondarySubjective EDSassessed before and after each intervention (day 1 and 15 of each intervention)Change in subjective excessive daytime sleepiness (EDS), measured with the Epworth Sleepiness Scale (ESS; score ranges from 0 to 24, higher scores indicate greater EDS)ClinicalTrials.gov

SecondarySubjective nocturnal sleep qualityassessed before and after each intervention (day 1 and 15 of each intervention)
Subjective nocturnal sleep quality, measured with the Parkinson's Disease Sleep Scale -2 (PDSS-2; score ranges from 0 to 60, higher scores indicate worse sleep quality) in PD patients and Pittsburgh Sleep Quality Index (PSQI; score ranges from 0 to 21, higher scores indicate worse sleep quality) in MCI patients
ClinicalTrials.gov
SecondaryExecutive Function and attentionassessed after each intervention (day 15 of each intervention)
Executive function (mental flexibility, verbal fluency, motor programming, sensitivity to interference, working memory, psychomotor processing speed), measured with the Trail Making Test (TMT; in seconds) B/A, the Regensburger Wortflüssigkeitstest (RWT; phonematic and semantic verbal fluency; in word count), the Luria's motor sequence test, the Victoria Stroop Task, the 2-back task, and the TMT A

SecondarySleep intensityassessed continuously during the intervention period (days 1-15 of each intervention)Sleep intensity, represented by Slow Wave Activity/ Slow Wave Energy (SWA/SWE), calculated from EEG recordings obtained every night at home with a frontal EEG electrode of the TSB AxoClinicalTrials.gov
SecondaryDepressive symptomsassessed before and after each intervention (day 1 and 15 of each intervention)Depressive symptoms, indicated by the Hospital Anxiety and Depression Scale (HADS; score ranges from 0 to 21, higher scores indicate more depressive symptoms), in MCI patientsClinicalTrials.gov
SecondaryVerbal episodic and visuospatial memory functionassessed after each intervention (day 15 of each intervention)
Verbal episodic and visuospatial memory function, measured with the Hopkins Verbal Learning Test (HVLT; score ranges from 0 to 12, higher scores indicate better performance), and Brief Visuospatial Memory Test (BVMT; score ranges from 0 to 12, higher scores indicate better performance), in MCI patients
