What is PTSD in Children? Symptoms and Signs of Post-Traumatic Stress Disorder

Post-Traumatic Stress Disorder (PTSD) in children can be triggered by various overwhelming events. These include experiencing or witnessing severe events such as natural disasters, physical violence, or accidents. For younger children, especially those under the age of six, undergoing invasive medical procedures, surgeries, or intense medical treatments can also lead to trauma. Witnessing a loved one experience a traumatic event is another significant catalyst.
The Prevalence of PTSD in Children
According to research from Stanford Children's Health, about 4% of children under the age of 18 experience a form of trauma that leads to PTSD during their lifetime. Among children and adolescents exposed to trauma, the National Institute of Mental Health reports that around 7% of girls and 2% of boys eventually receive a diagnosis of PTSD.
Recognizing the Symptoms of PTSD in Children
The symptoms of post-traumatic stress disorder in children generally fall into four main categories: sudden, intrusive thoughts and memories of the event; avoidance of reminders; negative shifts in mood and thoughts; and persistent anxiety or physical signs of stress.
Common signs include unwanted, sudden memories of the event, or acting out the trauma through flashbacks where the child feels as if the event is happening again. Children might also show extreme distress or hyper-vigilance when exposed to minor triggers. Often, the theme of the trauma persistently appears in their playtime activities or drawings.
Avoidance is another key symptom. Children may refuse to participate in activities or meet with people associated with the event. They might block out memory of the incident, express persistent beliefs that the world is fundamentally unsafe, or experience ongoing feelings of anger, shame, and fear. You may also notice them pulling away from family and friends, struggling to experience positive emotions like joy and love, or experiencing rapid mood swings.
Additionally, children may show regressive behaviors, such as bedwetting or thumb-sucking, and become hyper-sensitive to separations, finding it very difficult to leave their parents. They might remain in a constant state of high alert, reacting intensely to minor noises or changes. While these symptoms typically appear within a month of the traumatic event, in some cases, they may lie dormant for months until a trigger brings them to the surface. If symptoms persist for more than a month, seeking professional psychological support is crucial.
How Parents Can Support Their Children
Every child needs time to adapt and heal after a traumatic event. During this sensitive period, they need your love, patience, and understanding more than ever. Here are some gentle ways to support them:
First, talk about their feelings only when they are ready. If your child isn't prepared to open up, avoid pushing them. Instead, offer alternative outlets for self-expression, such as drawing, writing stories, or journaling. Always validate their emotions, reminding them that whatever they are feeling is completely natural.
Second, help them regain a sense of control. Encourage your child to make age-appropriate choices in their daily routine. Since trauma can leave children feeling powerless, making simple decisions can be incredibly grounding. Reassure them clearly and consistently that the event was not their fault.
Third, be gentle with regressive behaviors. To feel safe, your child might want to sleep with the lights on or have you sit by their bed until they fall asleep. Avoid criticizing these behaviors; instead, offer comfort, reassurance, and a sense of security.
Finally, remember that you may have been deeply affected by the traumatic event as well. Taking care of your own mental and physical well-being is essential. You can only fully support your child when you are feeling grounded. If you need guidance on how to navigate this journey, do not hesitate to seek professional help from a child psychologist.
