- Safety Adverse Events [ Time Frame: 2 weeks ]Number of participants with spontaneously reported treatment-related adverse events
- Epworth Sleeping Scale (ESS) [ Time Frame: 2 weeks ]Range of the scale : 0 to 24. A low score indicates a good outcome. Results shown are corresponding to a change from baseline of the ESS score.
- Psychomotor Vigilance Test (PVT) : Reaction Time (Miliseconds) Change From Baseline [ Time Frame: 2 weeks ]PVT measures reaction time in milliseconds. The results below are corresponding to the reaction time change from baseline.
- Montreal Cognitive Assessment Battery (MoCA) [ Time Frame: 2 weeks ]
MoCA score reflects the cognitive capacities of a person. Range of the total score of 10 test items: 0 to 30 points. A high score indicates good cognitive functioning. A score of 26 and above is considered normal.
The results below are shown as change from baseline of the MoCA score.
- Efficacy in Improving Sleepiness (ESS). Responders Rate, Change From Baseline [ Time Frame: 2 weeks ]ESS score responder rate, defined as the proportion of subjects with at least 25% ESS improvement from baseline, at the end of each treatment period
- Efficacy in Improving Sleepiness (ESS). Patients in Remission, Change From Baseline [ Time Frame: 2 weeks ]Number of patients in remission (=without residual sleepiness), i.e. ESS < 11 at the end of each treatment period
