Children whose parents have depression are at a greater risk of being depressed. While depression affects all ages and both genders, girls are more likely to develop depression during adolescence. Research shows that depression is also a risk factor for suicide. As many as 2 to 3 percent of children ages 6 to 12, and 6 to 8 percent of teens may have serious depression, and an estimated 2.8 million adolescents (ages 12 to 17) in the United States had at least one major depressive episode in 2014. There are two types of depression: major depression and dysthymia. Major depression lasts at least two weeks and may occur more than once throughout your child’s life. Your child may experience major depression after a traumatic event such as the death of a relative or friend. Dysthymia is a less severe but chronic form of depression that lasts for at least two years.  When symptoms last for a short period of time, it may be a passing case of “the blues.” But if they last for more than two weeks and interfere with regular daily activities and family and school life, your child may have a depressive disorder.
