ST. LOUIS, Aug. 4 (UPI) -- Depression among preschoolers appears to be a continuous, chronic condition rather than a transient developmental stage, U.S. researchers said.
Dr. Joan L. Luby and colleagues at Washington University School of Medicine in St. Louis studied 306 preschoolers ages 3-6. Of these, 75 met criteria for major depressive disorder, 79 had anxiety or disruptive disorders, but not depression, and 146 did not meet criteria for any psychiatric disorder.
