When people hear "trauma," they often think of extreme events — combat, assault, natural disasters. But trauma isn't defined by what happened to you. It's defined by how your nervous system responded.
Defining Trauma
Trauma occurs when an experience overwhelms your capacity to cope, leaving lasting effects on your physical, emotional, and psychological wellbeing.
As trauma researcher Dr. Gabor Maté says: "Trauma is not what happens to you. It's what happens inside you as a result of what happened to you."
Research shows that trauma literally changes brain structure and function, affecting areas responsible for memory, emotion regulation, and stress response.
Types of Trauma
Acute Trauma
A single overwhelming event: an accident, assault, sudden loss, medical emergency.
Chronic Trauma
Repeated and prolonged exposure: ongoing abuse, domestic violence, childhood neglect.
Complex Trauma
Multiple traumatic events, often of an interpersonal nature, usually beginning in childhood.
Developmental Trauma
Trauma experienced during critical periods of brain development, affecting core beliefs about self and others.
Intergenerational Trauma
Trauma passed down through generations, affecting families and communities. Epigenetic research shows this has a biological basis.
What Counts as Trauma?
Beyond obvious events, trauma can include:
- Emotional neglect or invalidation
- Chronic stress or uncertainty
- Medical procedures or illness
- Bullying
- Divorce or family dysfunction
- Living in an unpredictable environment
- Being misattuned to by caregivers
If you're experiencing persistent anxiety or depressive symptoms, unprocessed trauma might be a factor.
How Trauma Affects the Brain
Neuroimaging studies show trauma impacts:
- Amygdala: Becomes hyperactive, triggering false alarms
- Prefrontal cortex: Reduced activity, impairing decision-making and impulse control
- Hippocampus: Can shrink, affecting memory processing
- Nervous system: Gets stuck in fight, flight, or freeze mode
Signs You Might Be Carrying Trauma
- Hypervigilance — always scanning for threats
- Difficulty trusting others
- Emotional numbness or dissociation
- Flashbacks or intrusive memories
- Difficulty regulating emotions
- Physical symptoms (chronic pain, illness)
- Relationship difficulties
- Negative self-beliefs
These often show up as anger triggers or boundary issues.
Trauma Is Not Your Fault
Let's be clear: whatever happened to you was not your fault. Your responses — however they manifested — were survival strategies. They made sense at the time.
Healing Is Possible
Research shows the brain remains plastic throughout life. With proper support, trauma can be processed and healed. Evidence-based treatments include:
- EMDR (Eye Movement Desensitization and Reprocessing)
- Trauma-focused CBT
- Somatic therapies
- Internal Family Systems
- Neurofeedback
Healing isn't about forgetting. It's about processing experiences so they no longer control your present.
