Patients were retrospectively evaluated in terms of medical interview, sleep questionnaires, a standard polysomnography study, and subdivided in subgroups according to disorder duration. We compared patient’s results to a control group. 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»
