REM latency in endogenously depressed adolescents.
Twenty-three adolescents with DSM-III major depressive disorder (endogenous subtype) and 23 normal controls were studied polysomnographically (PSG). The depressed group showed significantly shortened REM latencies (P = 0.005) and longer sleep latencies (P = 0.04). No other PSG measures differentiated the two groups. The implications of these findings for adolescent depression are discussed.
