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.

METHOD: 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.

CONCLUSION: Short REM latency is associated with depression in the CFS population.
