Trauma is a common experience, with around 70% of people experiencing a traumatic event worldwide.^[1] People can respond to trauma in unique and individual ways. However, dissociation is one of the most common reactions, with reports showing around 7% of the population having experienced a dissociative disorder at some point.^[2]

If you feel concerned and worried about how childhood trauma and dissociation may impact your teen’s mental health, you aren’t alone. This page will help you understand:

What dissociation can look like in adolescence, and how childhood trauma impacts the brain and body.
Why dissociation can become a coping mechanism for childhood trauma.
The common dissociation symptoms and types of dissociative disorders in teens.
How trauma treatment helps with dissociation.

What Is Dissociation in Teens?

Dissociation is when someone feels detached from reality, themselves, and the world around them.^[3] Dissociative disorders are less documented in children and adolescents than in adults. However, some studies have shown that dissociative disorder occurs in around 5% of the general youth population and in about 19% to 25% of those who experienced trauma.^[4]

Dissociation symptoms can range from mild daydreaming or being extremely focused to feeling “outside of the body” or disconnected from thoughts and feelings. Basically, dissociation can make your teen feel separated from themselves or from what’s happening in the present moment.

For example, you might hear your teen say:

“I feel like I’m watching myself from outside my body.”
“Everything around me feels fake.”
“I don’t remember what happened after I got upset.”
“I know I was there, but it feels like it happened to someone else.”
“Sometimes I feel like different parts of me want different things.”

For teens who experienced childhood trauma, the effects can cause their brains to disconnect as a coping strategy and a way to protect them.

How Childhood Trauma Can Affect the Teenage Brain and Body

Trauma, especially childhood trauma or repeated experiences of trauma, can change the brain. After a traumatic experience, the amygdala, which is the area of the brain responsible for detecting threats, goes into overdrive.^[5] With the amygdala on overdrive, your teen may feel more jumpy or on edge, and even small triggers might feel overwhelming.

The childhood trauma effects also change the hippocampus, which is the area of the brain responsible for organizing and storing memories. Research has shown that in both post-traumatic stress disorder (PTSD)and dissociative identity disorder, people show a small volume in the hippocampus.^[6] This small volume may account for why people who experience trauma can have a difficult time remembering events or why they might feel disconnected from their experiences.

Examples of adolescent trauma may include:

Childhood abuse trauma, including physical, sexual, or emotional.
Neglect.
Bullying.
Witnessing violence.
Sudden loss.
Medical trauma.
Ongoing instability at home.

Over time, trauma can shape how a teen responds to stress. And when they feel stressed, their brain may try to protect them by dissociating.

Why Dissociation Can Become a Coping Mechanism

For childhood trauma and dissociation, dissociating often becomes a means of protection. In the middle of a traumatic experience, if your teen is unable to physically leave a frightening situation, their mind may create distance instead. This distance can help protect them in the moment by lowering awareness of fear, pain, or helplessness.

But even after the danger has passed, your teen may still find themselves disconnecting, especially during moments of stress, conflict, or overwhelming situations. They may not purposefully be choosing this response. It’s their body shutting down as a way to create a greater sense of safety.^[3]

Rather than your teen being “lazy” or avoiding situations on purpose, dissociation symptoms are often a sign that their nervous system is trying to protect them and needs support.

Common Dissociation Symptoms Parents May Notice

Dissociation can look different from teen to teen. Some teens can explain what’s happening. Others might only know that they feel “weird,” “blank,” or “not real.” In fact, parents may notice changes before a teen has the words to describe them.

Common dissociation symptoms you may notice in your teen might include:

Staring off, seeming “checked out,” or losing track of time.
Forgetting conversations, plans, or parts of the day.
Feeling numb, emotionally flat, or detached from their body.
Saying the world feels “unreal” or “dreamlike.”
Describing themselves as being on “autopilot.”
Not recognizing themselves in the mirror.
Becoming confused after stressful situations.
Having sudden shifts in mood, voice, posture, or behavior.
Feeling like different “parts” of themselves take over.
Finding it hard to explain why they reacted strongly.
Shutting down during conflict.
Feeling distant from people they care about.

These symptoms can overlap with:

Anxiety.
Depression.
PTSD.
Attention-deficit hyperactivity disorder (ADHD).
Sleep problems.
Other teen mental health conditions.

This is one reason professional assessment is important. A trained clinician can look at the full picture instead of focusing on one behavior in isolation.

Types of Dissociative Disorders in Teens

Not every teen who dissociates has a dissociative disorder. However, when dissociation becomes persistent, distressing, or disruptive, a clinician may assess for one of these conditions. Here are the different types of dissociative disorders:

Depersonalization/Derealization

Depersonalization-derealization disorder (DPDR) is a type of dissociative disorder where your teen might feel disconnected from themselves or the world around them.^[7] If your teen has DPDR, they might feel like they’re watching from outside their body or that their thoughts, voice, or movement don’t fully feel like their own. They might also feel like other people or their surroundings are fake or dreamlike.

Dissociative Amnesia

If your teen has dissociative amnesia, they’re likely to experience gaps in their memory, especially related to the traumatic event.^[8] They might not remember parts of the experience, certain periods of childhood, or what happened during a highly stressful moment. The memory gaps go beyond ordinary forgetfulness.

Dissociative Identity Disorder

Dissociative identity disorder (DID), previously called “Multiple Personality Disorder”, is often a result of repeated childhood trauma and a way to protect against unpleasant memories.^[9] DID involves having two or more separate identities, called “parts,” each with its own memories, emotions, behaviors, and characteristics.^[10] Usually, when someone with DID shifts parts, they also experience gaps in memory.

How Trauma Treatment Helps Teens With Dissociation

Effective trauma treatment can help your teen understand and manage their dissociation symptoms and the effects of trauma. Through trauma treatment, your teen can learn to:

1. Build Safety First

Effective trauma treatment in teen mental health starts with building safety. A trauma-informed therapist can help your teen feel safe in the present by:

Identifying triggers.
Understanding their body’s cues.
Learning what helps them return when dissociation begins.

Building safety also means emotional safety. So the therapist will not judge, rush, or pressure your teen to share more than they can handle.

2. Practice Grounding Skills

Once your teen builds safety and stability, they’ll start to learn and practice grounding techniques. Grounding skills can help them reconnect with the present moment when they’re starting to dissociate.^[11] These tools may include:

Naming five things they can see.
Holding an ice pack or textured object.
Pressing their feet into the floor.
Taking slow breaths.
Noticing sounds in the room.
Stretching or gentle movement.
Journaling.
Drawing or using creative expression.
Repeating a phrase like “I am here now.”

Grounding doesn’t erase trauma, but it can help your teen feel more in control when symptoms appear.

3. Process Trauma at the Right Pace

With enough stability and grounding skills in place, a trauma therapist will work with your teen to help them slowly process the trauma. Depending on your teen’s needs, this might include:

Eye Movement Desensitization and Reprocessing (EMDR).
Dialectical behavior therapy (DBT).
Mindfulness-based practices.
Expressive therapies.
Trauma-focused cognitive behavioral therapy (TF-CBT).
A combination of approaches.

During this treatment, your teen will receive support to process what happened by staying connected to the present moment.

Trauma and identity also get intertwined, where your teen may not feel like themselves or recognize who they are after a traumatic experience. Teen mental health treatment helps them rebuild their sense of self and feel more confident in their ability to handle stress.

Childhood Trauma and Dissociation in Teens FAQ

Many people are confused and overwhelmed by dissociative disorders, and it can be especially scary when it’s your child experiencing these symptoms. We know that many parents have questions about trauma and dissociation, so the answers below will hopefully help clarify what may be happening and when a teen may need support.

Can childhood trauma cause dissociation in teens?

Yes, there are quite a few studies that show a connection between childhood trauma and dissociation.^[3] For many teens, the dissociation has become a way to cope with the scary or dangerous experiences, even long after the trauma has passed. It’s often a way for their nervous system to protect them from these unsafe or overwhelming experiences.

What are the types of childhood trauma?

There are many different types of childhood trauma. Trauma might include physical, sexual, or emotional abuse. It can also include neglect, medical trauma, bullying, refugee or race-based trauma, or repeatedly seeing violence against someone else.^[12] A child can experience acute trauma (a single, terrifying event), complex trauma (multiple events over a long period), or chronic trauma (ongoing distress).

What’s the difference between PTSD and dissociative disorders?

PTSD and dissociative disorder can overlap, especially since they’re both often related to trauma. The difference is that PTSD involves re-experiencing the trauma through flashbacks, hyperarousal, and avoidance. Dissociative disorders, on the other hand, center on memory loss, identity disturbances, and feeling out of touch with reality.

Can dissociative identity disorder develop from childhood trauma?

Yes, research has consistently connected dissociative identity disorder to childhood trauma, especially repeated episodes of childhood trauma.^[9] Though every person’s experiences and mental health journey are different.

How can Mission Prep Teen Treatment help teens with trauma and dissociation?
