title: Depression and short REM latency in subjects with chronic fatigue syndrome.
abstract: OBJECTIVE
  The hypothesized polysomnographic marker for depression, Rapid Eye Movement Latency (REML), was used to investigate two groups of subjects; Chronic Fatigue Syndrome (CFS)-not depressed and CFS-depressed.
  
  
  METHODS
  CFS subjects were classified into depressed and not depressed groups, using the Diagnostic Interview Schedule (DIS), and subsequently were studied in a sleep laboratory to ascertain REML.
  
  
  RESULTS
  Short REML showed a statistically significant correlation with the depressed state in CFS subjects.
  
  
  CONCLUSIONS
  Short REM latency is associated with depression in the CFS population.
