Sleep electroencephalograms (EEGs) of subjects with primary panic disorder
were compared to those of normal controls matched for age and sex.
Significant differences were found between patients and controls in sleep
latency, sleep efficiency, and stage 2 sleep duration. No differences were
found between the two groups in REM latency. Because depressed patients are
known to have reduced latency to REM sleep, these data add support to the
hypothesis that panic disorder and depression are distinct disorders.
