When a teen seems absent, dissociation may be the hidden cause

Long pauses, memory gaps and a dreamlike sense of unreality can signal dissociation in teenagers. Experts explain what parents should look for, how to help in the moment and when to seek urgent support.

For many parents, the first clue that something is wrong is not an outburst but a pause: a teen who seems mentally elsewhere, takes an unusually long time to answer, or later cannot recall a conversation that just happened. Ascend Healthcare says families often begin searching for answers after a young person describes feeling “not real” or as though they are observing their life from a distance. Mental health specialists describe dissociation as a break in the connection between thoughts, memories, feelings, surroundings or identity, and Mayo Clinic notes that it can emerge as a response to painful or overwhelming experiences.

The experience can be hard to recognise from the outside, because it often begins as an internal sense of detachment. Healthline and Medical News Today say teenagers may describe feeling unreal, foggy or as though the world has taken on a dreamlike quality, while some feel as if they are watching themselves from outside their own bodies. Memory gaps, emotional numbness and a distorted sense of time are also common features. Cleveland Clinic and WebMD both note that dissociation can affect a person’s connection to their surroundings, feelings and sense of self.

For parents, the outward signs may look like staring blankly, drifting away during conflict, answering slowly or seeming oddly flat in situations that would normally provoke an emotional reaction. Mayo Clinic says stress can make dissociative symptoms more noticeable, and Ascend Healthcare warns that episodes may cluster around reminders of trauma or other distressing experiences. The causes are not limited to trauma alone: anxiety, depression, severe sleep loss and substance use can also contribute, according to Healthline, Medical News Today and WebMD.

Experts say the immediate response should be calm and grounding. Rather than startling a teen or speaking loudly, parents are advised to use a steady voice, say the young person’s name and invite them to focus on the present by noticing their feet on the floor, holding something cold or naming objects in the room. Ascend Healthcare also recommends practising these skills during calm moments, so they are easier to use when stress rises. Healthline and Medical News Today say psychotherapy, including cognitive behavioural therapy, is often used to treat dissociative symptoms, while Mayo Clinic and Cleveland Clinic note that medication may be added in some cases.

Parents should seek professional help if dissociation happens often, disrupts school or relationships, or appears alongside self-harm, suicidal thoughts, confusion or unresponsiveness. In those situations, Ascend Healthcare advises contacting emergency support, including the 988 Suicide and Crisis Lifeline in the United States. Medical sources say it is also important to rule out physical causes, especially if symptoms begin suddenly or follow a head injury. The broader message from clinicians is that dissociation is not a sign that a teen is “going crazy”; it is a treatable response that often reflects overload, and with the right support, young people can learn to feel safer and more present.
