Depression in teens

How depression presents in teens

The DSM-5-TR criteria for major depressive disorder are the same in adolescents and adults, with one notable adjustment: in children and adolescents, irritable mood can substitute for depressed mood. This matters because irritability is often read by parents and teachers as defiance or attitude rather than as illness.

Common features in adolescent depression:

• Irritability, snapping, low frustration tolerance
• Withdrawal from friends, family, or previously enjoyed activities
• Sleep changes (often oversleeping, sometimes insomnia)
• Drop in school performance, missed assignments, increased absences
• Fatigue and a heavy, slowed feeling
• Increased screen time as a way to escape
• Self-criticism, guilt, hopelessness
• Talk of being a burden, of others being better off without them, or of suicide

Persistent depressive disorder (PDD) in children and adolescents requires depressed or irritable mood for at least one year, rather than the two years required in adults.

Screening

The PHQ-9 modified for adolescents (PHQ-A) is the most widely used screening tool. The Patient Health Questionnaire for Adolescents and the Patient Health Questionnaire Adolescent version are both validated. The American Academy of Pediatrics recommends universal annual depression screening beginning at age 12, ideally at well-child visits.

The U.S. Preventive Services Task Force gives screening for depression in adolescents (ages 12 to 18) a Grade B recommendation.

Suicide risk in adolescents

Suicide is one of the leading causes of death in U.S. adolescents (CDC). Risk is higher in adolescents with prior attempts, with a family history of suicide, with bullying or social rejection, with LGBTQ+ identity (especially when family or community support is low), with substance use, and during the period after discharge from inpatient psychiatric care.

Means restriction is one of the strongest interventions. A firearm in the home is the most lethal common method and one of the most modifiable risk factors. Off-site storage during a high-risk period reduces both the chance of an attempt and the chance that an attempt is fatal. Restricting access to medications (locked storage, smaller pharmacy fills) matters too.

If you may be in danger, call or text 988 in the United States, call 911, or go to the nearest emergency department. See crisis resources.

Treatment

Treatment of adolescent depression follows guidelines from the American Academy of Child and Adolescent Psychiatry (AACAP) and the GLAD-PC guidelines for primary care.

• Mild depression: Psychoeducation, supportive care, and active monitoring for six to eight weeks before starting active treatment, in many cases. CBT or IPT-A (interpersonal therapy adapted for adolescents) if symptoms persist or are functionally impairing.
• Moderate to severe depression: CBT, IPT-A, fluoxetine, or escitalopram. The TADS trial showed that combined fluoxetine plus CBT outperformed either alone in adolescents.
• Treatment-resistant depression: Switch to a second SSRI, augmentation, or specialty referral.

Fluoxetine and escitalopram are the only antidepressants with FDA approval for depression in adolescents. Other SSRIs are sometimes used off-label when needed. The first-line choice is usually fluoxetine because of the most extensive trial evidence in this age group.

The FDA boxed warning

All antidepressants carry an FDA boxed warning for increased risk of suicidal thoughts in children, adolescents, and young adults under 25 (through age 24), especially in the first weeks of starting or changing a medication. The absolute risk is small. The relative risk increase is real and is the basis for close monitoring.

Practical implications:

• Weekly clinical contact for the first four weeks, then biweekly for the next month, then monthly is the standard of care for adolescents starting an antidepressant.
• Any new or worsening suicidal thoughts during this period are a reason to call a prescriber the same day.
• Untreated adolescent depression also carries a meaningful risk of suicide. The decision to treat is balanced against this risk, not made in a vacuum.

Working with school

Depression often affects school performance and attendance. Two formal supports are worth knowing:

• 504 plan: A federal civil rights document under Section 504 of the Rehabilitation Act. Provides accommodations (extended time on tests, reduced workload, excused absences for treatment, quiet test rooms, regular check-ins with a counselor) for students with a condition that substantially limits a major life activity.
• IEP (Individualized Education Program): A more comprehensive plan under the Individuals with Disabilities Education Act (IDEA) for students whose condition affects learning enough to require special education services. Less commonly used for depression alone, more often when learning differences or significant emotional disability are involved.

The school counselor or psychologist is the usual starting point. A clinician's documentation of the diagnosis and recommended accommodations supports the request.

Supporting a teen with depression

The patterns that help most:

• Stay present without trying to fix. Listen. Sit with the discomfort.
• Side-by-side time (a drive, a walk, a meal) often surfaces more than face-to-face conversations.
• Maintain structure: regular sleep and wake times, meals, and at least one daily out-of-house activity.
• Limit lethal means access: firearms off-site, medications locked, sharps managed.
• Avoid pressure to "snap out of it"; it is not motivating and erodes trust.
• Stay involved with treatment without taking over. Adolescents do better when they feel agency in their care.
