Looking Closer at PTSD and Trauma-Related Conditions in Children

Post-Traumatic Stress Disorder, often called PTSD, can happen after a child experiences or witnesses something frightening, painful, or unsafe. This may include abuse, neglect, violence, the death of someone close, a serious accident, medical trauma, being removed from home, or living in an unstable environment.

Not every child who goes through trauma will develop PTSD. Some children may have trauma symptoms, anxiety, depression, behavior changes, or adjustment disorder instead. A doctor or mental health professional looks at how long the symptoms have lasted, how serious they are, and how much they affect the child’s daily life.

Children do not always have the words to explain what happened or how they feel. Instead, trauma may show up through behavior. A child may have nightmares, trouble sleeping, angry outbursts, fearfulness, clinginess, stomachaches, headaches, trouble focusing, or problems at school. Some children may avoid certain people, places, sounds, smells, or situations that remind them of what happened. Others may seem numb, withdrawn, or “shut down.” The CDC notes that children with PTSD may relive the event through thoughts or play, have nightmares or sleep problems, become upset by reminders, avoid reminders, or seem constantly on alert.

Trauma can also make a child’s body feel like it is always watching for danger. This is sometimes called being “on guard.” The child may startle easily, struggle to concentrate, have trouble falling asleep, or become irritable or aggressive. The National Institute of Mental Health explains that these stress responses can interfere with sleeping, eating, concentrating, and daily life.

For younger children, trauma may look different. They may cry more, become clingy, have tantrums, become afraid of the dark or being alone, or go back to behaviors they had outgrown, such as bed-wetting or thumb-sucking. NIMH also notes that some young children may act out parts of the traumatic event through play.

The good news is that children can heal. Safe relationships, steady routines, therapy, school support, and caring adults can make a big difference. Families do not have to figure this out alone. Advocacy Links can help families find the right resources, understand available supports, and connect with programs such as Wraparound and community services. As noted in the grandparents and trauma article, children who experience trauma need safe, stable, and supportive environments to begin healing, and caregivers also need support along the way.
