 Depression goes beyond moodiness.
Temperamental teens are common. But moodiness doesn’t mean depression, Dr. Rubenstein said. Neither does sleeping a lot, which is typical for teens; they actually require more sleep than adults and have trouble falling asleep early.
So how do you know the difference between normal teenage doldrums and depression? Consider if there’s been “a real change in the functioning of [your] child’s behavior,” Strober said. You also might notice changes in appetite and sleep, poor school performance, an inability to concentrate, lack of interest and withdrawal from regular social activities.
