Patients were retrospectively evaluated in terms of medical interview, sleep questionnaires, a standard polysomnography study, and subdivided in subgroups according to disorder duration.

Insomnia and control groups were significantly different in terms of TST, SE, SOL, N1 sleep, REM sleep, REM latency and number of REM episodes (p<0.05). For the group of ≤1 year of insomnia disorder all PSG parameters were statistically different from controls, except N2% and N3%, REM latency, and number of REM episodes. In the groups of 2 to 4 years, 10 to 19 years, and ≥ 20 year.. View More»
