Understanding Trauma: A Clinical Psychologist’s Perspective

Evidence-based psychoeducation about trauma: what it is, how it affects us, and how healing is possible.

What Is Trauma?

Trauma is not simply a distressing event, it is the lasting impact that an overwhelming experience has on a person’s nervous system, sense of self, and ability to function. The word comes from the Greek for “wound”, and that framing is important: trauma is an injury, not a weakness or a choice.

Trauma can result from a single overwhelming event, a prolonged period of adversity, or cumulative experiences of stress, loss, or relational harm. It can affect anyone, regardless of age, background, or perceived resilience.

Examples of Trauma

Trauma is not one-size-fits-all. Clinicians distinguish between several types, each with different presentations and treatment implications.

‘Single-Incident’ Trauma

A single, time-limited traumatic event, such as a road traffic accident, assault, natural disaster, medical emergency, or sudden bereavement. The person often has clear memories of the event and a defined “before and after”.

Complex Trauma

Repeated or prolonged trauma, often occurring in childhood and within relationships, such as emotional, physical, or sexual abuse, neglect, domestic violence, or living in an unsafe or unpredictable environment. Complex trauma affects identity, attachment, and emotional regulation in pervasive ways.

Developmental / Childhood Trauma

Adverse childhood experiences (ACEs), including abuse, neglect, household dysfunction, or loss of a caregiver, that occur during critical developmental windows. These can shape the developing brain, attachment patterns, and stress response systems in lasting ways.

Medical Trauma

Trauma arising from serious illness, medical procedures, childbirth complications, or time in intensive care. Often underrecognised, medical trauma can leave lasting fear, hypervigilance around health, and avoidance of medical settings.

Collective & Systemic Trauma

Trauma experienced by communities or groups, including racism, discrimination, refugee experiences, war, or generational trauma passed through families. The impact of systemic and collective trauma is increasingly recognised in clinical practice.

How Trauma Affects the Brain and Body

One of the most important things to understand about trauma is that it is a physiological experience, not just a psychological one. Trauma is stored in the body and the nervous system, not just in conscious memory. This is why trauma responses can feel so automatic, overwhelming, and difficult to “think” your way out of.

When we encounter threat, the brain’s alarm system, the amygdala, activates the stress response before the thinking brain (prefrontal cortex) has time to process what is happening. This is adaptive in genuine danger. In trauma, however, the nervous system can become stuck in a state of threat-readiness long after the danger has passed.

The Survival Responses: Fight, Flight, Freeze, Fawn

Fight

Anger, irritability, aggression, or feeling ready to confront threat. May present as rage, defensiveness, or difficulty managing frustration.

Flight

Anxiety, restlessness, avoidance, and the urge to escape. May look like busyness, hyperactivity, or difficulty sitting still with difficult feelings.

Freeze

Feeling stuck, numb, dissociated, or shut down. The nervous system immobilises when fight or flight feel impossible. Often mistaken for laziness or indifference.

Fawn

Appeasing, people-pleasing, or prioritising others’ needs to avoid conflict or danger. Common in those with relational or developmental trauma histories.

These responses are not character flaws, they are the nervous system doing exactly what it evolved to do. Understanding them as survival adaptations is a key part of trauma-informed care.

Common Symptoms and Presentations

Trauma can present in many different ways. Symptoms may appear immediately after a traumatic event or emerge months or even years later. They can affect every area of life — emotional, physical, relational, and cognitive.

Re-experiencing

  • Flashbacks — vivid, intrusive re-living of the trauma
  • Nightmares or disturbed sleep
  • Intrusive memories or images
  • Emotional or physical reactions to reminders (triggers)

Avoidance

  • Avoiding people, places, or situations that serve as reminders
  • Emotional numbing or detachment
  • Difficulty talking or thinking about the trauma
  • Loss of interest in previously enjoyed activities

Hyperarousal

  • Hypervigilance — constantly scanning for danger
  • Being easily startled
  • Difficulty sleeping or concentrating
  • Irritability, anger, or emotional reactivity

Negative Cognitions & Mood

  • Shame, guilt, or self-blame
  • Beliefs such as “I am broken”, “the world is unsafe”, “I cannot trust anyone”
  • Persistent low mood or depression
  • Feeling disconnected from others

Evidence-Based Treatments for Trauma

Trauma is treatable. With the right support, people can and do recover — not just managing symptoms, but genuinely processing and integrating traumatic experiences so they no longer dominate daily life. NICE guidelines recommend several evidence-based approaches:

Trauma-Focused CBT (TF-CBT)

A NICE-recommended first-line treatment for PTSD. TF-CBT involves carefully revisiting and processing the traumatic memory, challenging unhelpful beliefs that formed as a result, and updating the trauma memory so it is experienced as a past event rather than an ongoing present threat.

EMDR — Eye Movement Desensitisation and Reprocessing

EMDR is a NICE-recommended, highly effective therapy for PTSD. It uses bilateral stimulation (such as guided eye movements) whilst the person briefly focuses on the traumatic memory, helping the brain to reprocess and integrate the experience. EMDR does not require the person to talk about the trauma in detail.

Schema Therapy

Particularly helpful for complex and developmental trauma, schema therapy works with deep-seated beliefs (“schemas”) formed in childhood — such as “I am unlovable”, “I am defective”, or “the world is dangerous” — and the coping modes that developed around them. It integrates cognitive, experiential, and relational techniques.

Compassion-Focused Therapy (CFT)

CFT is especially valuable for trauma survivors who experience high levels of shame and self-criticism. It works to develop the person’s capacity for self-compassion and to soothe the threat system — addressing the internal experience of being one’s own harshest critic.

Somatic & Body-Based Approaches

Because trauma is held in the body, approaches that work with physical sensation — such as Sensorimotor Psychotherapy and somatic grounding techniques — can be powerful adjuncts to trauma therapy, particularly for those who find verbal processing difficult.

All trauma therapy at Reframe Psychology begins with a thorough assessment and a period of stabilisation and safety-building before any trauma processing work begins. We never rush this phase — it is the foundation on which lasting recovery is built.

What Trauma Therapy at Reframe Psychology Looks Like

Our clinical psychologists offer specialist, trauma-informed therapy for adults, young people, and neurodivergent individuals. We work with a wide range of trauma presentations — from single-incident PTSD to complex developmental trauma — and we adapt our approach to each person’s unique history, needs, and neurotype.

Our trauma therapy is:

  • Paced and collaborative: you are always in control of the pace of the work. Nothing happens without your agreement.
  • Safety-first: we invest time in building stability and coping resources before any trauma processing begins
  • Shame-sensitive: we understand that shame is often at the heart of trauma, and we work with great care around this
  • Neurodiversity-affirming: we understand how trauma intersects with autism, ADHD, and sensory differences, and we adapt our methods accordingly
  • Evidence-based: grounded in NICE-recommended approaches including TF-CBT and EMDR, alongside schema therapy and CFT where indicated
  • Formulation-led: we develop a shared understanding of your unique experiences before deciding on the most appropriate treatment pathway
