Adolescent Depression: Symptoms, Causes, and Treatment

Depression in adolescents manifests through various emotional and behavioral changes. These can include a loss of interest or motivation, persistent feelings of guilt, concentration difficulties, thoughts of death, and sleep or appetite disturbances. Teenagers may also experience feelings of worthlessness, hopelessness, a decline in social activities, irritability, a drop in academic performance, lower self-confidence, and an increased dependency on the internet, gaming, or computers.

What distinguishes depression from the temporary sadness or low mood that everyone experiences from time to time is its persistence—these symptoms must be observed for at least two weeks. This state significantly disrupts a teenager's social relationships and daily functioning. Depression can also be accompanied by other issues such as anxiety, social phobia, or somatization.

In severe cases, suicidal ideation or behavior may occur. Some warning signs that a teenager might be contemplating suicide include: making jokes about death or dying, saying things like "Everything would be better if I weren't here," expressing romanticized views of death, writing poems or stories about death, experiencing frequent accidents resulting in injury, or saying goodbyes to family and friends that feel unusually final.

Possible Causes of Depression

Depression during adolescence can arise from both biological and psychosocial factors. From a biological perspective, research points to the functioning of neurotransmitters like serotonin and norepinephrine in the brain. Psychosocially, contributing factors can include parental depression, experiences of loss, parental divorce, abuse, and a lack of communication within the family. Additionally, the teenager's own personality traits can influence the severity and duration of the depressive episode.

Treatment of Depression in Teenagers

Effective treatment of adolescent depression always involves psychotherapy, and in certain cases, antidepressant medication may be recommended. The decision to use and monitor antidepressant medication must be closely managed by a child and adolescent psychiatrist. However, medication is only one part of the solution; combining it with therapy is crucial to explore the underlying factors that trigger and maintain the depression, while helping the teenager develop healthy problem-solving and coping skills.
