Similar to depression in adults, scientists do not know the specific cause or causes of teen depression. They do believe that that the onset of depression is frequently caused by a combination of genetic, psychological, and environmental factors. In other words, there is no one cause of depression.
As well as showing many of the same symptoms of adult depression, some symptoms of teenage depression are: 1  A downward trend in performance at school or college. 2  Change in personal hygiene and appearance. 3  Destructive and/or defiant behavior.  Hallucinations or unusual beliefs.
