Understanding Trauma and the Nervous System

Trauma is not simply exposure to a stressful or overwhelming event. Trauma can be understood as an experience that continues to overwhelm the nervous system, even after the event has ended, leading to ongoing emotional and physical distress in the present.

After a difficult experience, it is normal to feel unsettled, anxious, or emotionally drained for a period of time. For many people, these reactions gradually settle as the nervous system returns to balance and the experience is integrated as something that has passed.

For others, however, the nervous system remains activated or shut down. Trauma responses may persist, interfere with daily functioning, and increase vulnerability to mental health difficulties such as anxiety, depression, or post-traumatic stress disorder (PTSD).

These responses are adaptive survival responses — not signs of weakness or failure.

Common Trauma Responses

Trauma can affect multiple systems at once — the body, emotions, thoughts, and relationships.

Common trauma responses may include:

Re-Experiencing Symptoms

  • Intrusive or distressing memories
  • Flashbacks or feeling as though the event is happening again
  • Nightmares

Emotional Responses

  • Anxiety or panic
  • Strong feelings of fear, anger, guilt, shame, or sadness
  • Emotional numbness or difficulty accessing feelings

Avoidance and Withdrawal

  • Avoiding reminders of the event
  • Social withdrawal or isolation
  • Difficulty opening up or emotionally connecting with others

Nervous System and Body Responses

  • A constantly alert or easily triggered nervous system
  • Feeling both agitated and shut down
  • Feeling unreal or disconnected from the body or surroundings
  • Sensory sensitivity (e.g. to light, sound, touch)

Cognitive and Concentration Difficulties

  • Difficulties with attention and focus
  • Brain fog or racing thoughts
  • Memory difficulties

Beliefs About Self and Others

  • Unhelpful beliefs about yourself, others, or the world
  • Reduced sense of safety or trust

Mental Health Difficulties Following Trauma

Trauma can increase the risk of developing mental health difficulties, including:

  • Anxiety disorders
  • Depression
  • Obsessive-compulsive disorder (OCD)
  • Post-traumatic stress disorder (PTSD)

Some people also notice changes in attention, emotional regulation, or impulse control that may resemble ADHD-type behaviours following trauma. Others may not meet criteria for a formal diagnosis but still experience significant changes in how they feel, relate, and function.

For many people, trauma is held as a body-based experience rather than something that can be easily put into words.

Trauma Therapy: How I Can Help

While no one can undo what has happened, psychological therapy can help address the imprints trauma leaves on the mind and body.

I provide trauma-informed, evidence-based therapy for difficulties including:

  • Single-incident trauma (e.g. traffic accidents, falls)
  • Witnessing or vicarious trauma
  • Difficult or traumatic birth experiences
  • Bullying and humiliation
  • Multiple or cumulative stressful life events
  • Social anxiety
  • Grief and loss
  • Adverse childhood experiences
  • Emotional, psychological, or physical neglect
  • Sexual assault or abuse
  • Medical trauma
  • Attachment-related trauma
  • Phobias and specific fears

Where appropriate, EMDR therapy and other evidence-based approaches may be used to support recovery. Therapy is always collaborative, paced carefully, and guided by safety and choice.

Trauma-Informed, Evidence-Based Care

Trauma-informed therapy means:

  • Prioritising emotional and nervous system safety
  • Building regulation and coping skills
  • Going at a pace that feels manageable
  • Respecting autonomy and choice
  • Adapting therapy for neurodivergent clients

Healing does not require reliving trauma. It involves helping the nervous system process and integrate experiences so they no longer overwhelm the present.
