Adolescent Depression: What It Is and How to Recognize It

The adolescent mind is built in a way that makes warning signs easy to dismiss as moodiness or "just a phase." Knowing exactly what to look for makes all the difference.

What makes up the adolescent mental health "basket"

Dr. Saulitis describes a characteristic cluster of conditions common among today's teenagers: depression, anxiety, and eating disorders frequently co-exist, each amplifying the other. This is not simply "a bad mood" — these are interconnected signs that deserve serious attention.

The key signal parents most often miss

The most deceptive symptom is a sharp shift in the teenager's state depending on whether peers are around. Alone, the teenager withdraws — listens to gloomy music, writes dark or catastrophic texts, dresses in all black. The moment friends arrive, they come alive: laughing, chatting, ordering pizza. When friends leave, the previous state returns.

Parents typically interpret this switching as proof that "there is no depression." In reality, it is one of depression's signatures.

What to watch for

• The teenager spends increasing amounts of time alone with devices
• Withdrawal, dark interests, negative or catastrophic writing — when alone
• A sharp "switch on" when peers arrive and an equally sharp "switch off" when they leave
• Refusal to engage in required activities (school, responsibilities) while remaining active in social settings

A change in behaviour is the primary signal. Observe how the teenager is when alone — not only how they appear in company.

What to do if you notice these signs

Record specific observations: what the teenager does when alone, how their mood and behaviour shift. A written picture of behaviour is valuable material for a conversation with a specialist. The earlier you pay attention, the greater the opportunity to prevent serious consequences.
