Knowing if you have PTSD from childhood trauma involves recognizing persistent symptoms like flashbacks, nightmares, severe anxiety, irritability, avoidance of reminders, emotional numbness, sleep problems, concentration issues, and trouble with relationships or trust, often stemming from prolonged or repeated adverse experiences, not just a single event, and significantly impacting your life for weeks or longer. While self-assessment is a start, a formal diagnosis requires professional evaluation to distinguish from general stress, noting that childhood trauma often leads to Complex PTSD (C-PTSD).
Signs of childhood trauma
Feeling like the trauma is happening again (flashbacks)
Although some people recover within 6 months, others have symptoms that last for 1 year or longer. People with PTSD often have co-occurring conditions, such as depression, substance use, or one or more anxiety disorders. After a dangerous event, it is natural to have some symptoms.
To receive a diagnosis of PTSD, a person must have at least one re-experiencing symptom, at least three avoidance symptoms, at least two negative alterations in mood and cognition, and at least two hyperarousal symptoms for a minimum of one month.
We look at some of these conditions in more detail below.
The 5 core signs of PTSD fall into categories: Re-experiencing (flashbacks, nightmares), Avoidance (staying away from reminders), Negative Changes in Mood & Cognition (guilt, detachment, loss of interest), Changes in Arousal & Reactivity (hypervigilance, easily startled, irritability), and sometimes Physical Symptoms like chronic pain or headaches, all stemming from a trauma, though the exact symptoms vary.
PTSD is diagnosed by a psychiatrist through a mental health assessment. Your GP should carry out an initial assessment to decide what care you need. Your assessment should include information about your physical needs, mental needs, social needs, and risk.
These triggers can be external, such as sights, sounds, smells, or locations that are associated with the trauma. They can also be internal, such as certain thoughts, emotions, or physical sensations that are similar to those experienced during the traumatic event.
The main treatments for post-traumatic stress disorder (PTSD) are talking therapies and medicine. Traumatic events can be very difficult to come to terms with, but confronting your feelings and getting professional help is often the only way of effectively treating PTSD.
Flashbacks play a significant role in the experience of PTSD. They are characterized by vivid and disturbing recollections of the traumatic event, which can feel as if the person is reliving the experience all over again.
The selective serotonin reuptake inhibitor (SSRI) medicines sertraline (Zoloft) and paroxetine (Paxil) are approved by the Food and Drug Administration (FDA) to treat PTSD . Venlafaxine (Effexor XR) also may be prescribed.
Relation to Traumatic Events
These nightmares are often related to the traumatic event and can be triggered by reminders of the event. For example, a veteran with PTSD may have nightmares about combat experiences, while a survivor of sexual assault may have nightmares about the assault.
While some people do experience periods where they don't remember traumatic events, this can happen through normal forgetting processes rather than a special “repression” mechanism. That said, many trauma survivors experience memory gaps, fragmented recall, or a sense that something happened without clear memories.
Unhealed trauma often appears as chronic people-pleasing, relationship struggles, anxiety, self-destructive coping, or persistent shame and emptiness. Trauma rewires the hippocampus, amygdala, and prefrontal cortex, affecting memory, emotion regulation, decision-making, and social interactions.
Child trauma occurs when young individuals (0-18 years) experience or witness events that threaten their or others' safety, such as accidents, natural disasters, violence, or significant loss.
PTSD is more than an emotional struggle — it physically rewires the brain, altering how fear is processed, memories are stored and emotions are regulated. Key brain regions affected include the amygdala, bed nucleus of the stria terminali, prefrontal cortex and hippocampus.
Post-traumatic stress disorder (PTSD) is a mental health condition that's caused by an extremely stressful or terrifying event — either being part of it or witnessing it. Symptoms may include flashbacks, nightmares, severe anxiety and uncontrollable thoughts about the event.
When our brain then recognises similarities between our present situation and our past trauma (e.g. a colour, smell or noise), it can activate the fight, flight, freeze, flop or friend response, even if we're not currently in danger.
Pete Walker's “Complex Trauma: From Surviving to Thriving,” explores the four F's of complex trauma, fight, flight, freeze, and fawn, to help survivors understand their coping mechanisms and reactions, and begin to work towards actions that may better serve them in their life and relationships.
