In this study the sleep of borderline patients and patients with primary
nondelusional depression showed sleep continuity disturbance and greater
REM activity and density (particularly during the first REM period) than
that of normal control subjects. First-night REM latencies were more
variable in the borderline than in the depressed group, but by the second
night both groups showed shorter REM latencies than the controls. The
similarities in EEG sleep suggest a relationship between borderline
disorder and the affective spectrum and cast doubt on the definition of the
borderline disorder as a pure character type.Abstract Teaser
