As a major component for validation of sleep analysis, a large normative
database was recorded at eight partner sites. Following an extensive recording
protocol, each record consists of
2 consecutive nights of 16-channel polysomnography
14 days of actigraphy (optional for patients)
4 sets of psychometric tests (paper-and-pencil, reaction time, vigilance)
sleep logs and questionnaires
medical examination results
The database consist of roughly 200 records from healthy controls over
the entire age spectrum from 20-90 years, and roughly 100 records from
sleep-disturbed patients:
