Using two different sleep questionnaires gave us valuable information as they measure different aspects of sleep disturbances.
To date, 88 different sleep disorders are internationally recognized.
Epileptiform discharges (EDs) were quantified in different sleep stages.
Both devices were able to successfully discern different sleep stages, summarized as light sleep, deep sleep, and REM.
The following parameters were calculated: time in bed, sleep latency, sleep period (time in bed – sleep latency), wake after sleep onset, total sleep time (sleep period – wake after sleep onset), sleep efficiency (total sleep time/sleep period), number of awakenings, REM latency and percentage amounts of different sleep stages (S1 S4 %, REM %).
The PSM allows combining sleep microstates into subsets and thus creating different sleep profile – structures.
Sleep research and sleep medicine usually distinguish a small number of different sleep stages according to the type of sleep (rapid eye movement sleep, or REM, vs. non-REM, or NREM) and the sleep depth within NREM.
Sleep problems were measured using the 12-item Medical Outcomes Study Sleep 18 (MOSS) scale, which is scored to yield six different sleep subscales and an overall sleep problems index (Sleep Problems Index II).
The Sleep Standard Evaluation Questionnaire (SEQ-Sleep) is a reliable and short tool with confirmed construct validity for sleep assessment in population-based observational studies.
