The SS1 subset includes sleep annotations and sleep stages.
Annotations:
- Expert annotations:
- Apnea/hypopnea
- Micro arousal

- Muscular artefacts
- Periodic limb movements of sleep (PLMS)
Sleep stage scoring :

- Page size (s) : 30
Notes: Mild cognitive impairment (MCI) : 15 subjects (as stated in the article) plus 2 limit cases (diagnosed MCI with updated criteria)

The sleep stages are the same as those included in the dataset named "SS1 Biosignals and Sleep stages".
Sleep stage scoring does not necessarily start at the beginning of the PSG recording.
