- Primary Outcome Measures
Name Time Method 1. Objective sleep architecture and brain oscillations will be investigated with polysomnography (PSG) recordings at every visit. Sleep measures include total sleep time, sleep onset latency, sleep efficiency (i.e., the ratio of total sleep time over time over the time spent in bed), time spent in each sleep stage and awake, sleep fragmentation (i.e., sleep stage changes), number of arousals, spindles and slow oscillations activity (count, density, timing, amplitude, frequency), spectral activity, eye movement.<br>2. Subjective sleep measures will be extracted from a sleep questionnaire answered in the morning after each visit. Subjective sleep measures include estimated total sleep time, sleep quality, wake duration and sleep onset latency. The sleep perception index will be calculated by dividing subjective sleep measures by objective sleep measures.
