Moody or Something More? Signs to Watch in Teen Boys

Published November 14, 2026 · Written from AAP, KidsHealth and other pediatric sources

Puberty brings mood swings, and most of the time that is normal. But persistent changes can be a sign that your son needs more support. This article follows CDC guidance and is not a diagnosis tool.

Normal worry versus something more

CDC says fears and worries are typical in children, but persistent or extreme fear and sadness could be due to anxiety or depression, and that the two often occur together.

Signs of depression, per CDC

Feeling sad, hopeless or irritable a lot of the time.
Not wanting to do or enjoy fun things.
Eating a lot more or a lot less than usual.
Sleeping a lot more or a lot less than normal.
Being tired and sluggish, or tense and restless, a lot of the time.
Trouble paying attention, or feeling worthless or guilty.

It may not look like sadness

This is the part that matters for boys. CDC says some children do not talk about their feelings and may not appear sad, and that depression can show up as acting out, seeming unmotivated, or being irritable or angry, which can lead adults to label a child lazy or a troublemaker. CDC also says anxiety can make children irritable and angry, and can show up as trouble sleeping, headaches, stomach-aches or fatigue.

How common is it?

CDC survey data for 2025 shows about 1 in 3 U.S. high school students felt persistently sad or hopeless in the past year, including 24 percent of male students. CDC also reports that among adolescents 12 to 17 in 2021 to 2023, 20 percent reported anxiety symptoms and 18 percent reported depression symptoms in the previous two weeks.

What to do

Talk to his pediatrician if changes last more than a couple of weeks or get in the way of school, friends or home life. CDC notes that some signs could be caused by other conditions, such as trauma.
CDC notes the U.S. Preventive Services Task Force recommends screening for depression in adolescents ages 12 to 18, so it is reasonable to ask about it at a checkup.
If you are worried he may hurt himself, call or text 988 (the Suicide and Crisis Lifeline), or call 911 in an emergency.
