Trauma

Cause #51b of 64 · neurological

Consensus: High - trauma effects on cognition well-established; treatment approaches evidence-based

Overview

Trauma isn't just psychological - it's physiological. Your nervous system learned to stay vigilant, and that hypervigilance consumes cognitive resources. The brain is so busy scanning for danger that there's nothing left for concentration, memory, or clear thinking. Trauma doesn't have to be a single dramatic event - chronic stress, neglect, and adverse childhood experiences count too.

Trauma isn't just psychological - it's physiological. Your nervous system learned to stay vigilant, and hypervigilance consumes cognitive resources.

1. 1. THE ACE SCORE: Take the Adverse Childhood Experiences questionnaire (free, 10 questions). ACE score >=4 is associated with dramatically increased risk of cognitive, mental, and physical health issues. This is validated science, not opinion. Source: Felitti et al., Am J Prev Med 1998 · 10.1016/S0749-3797(98)00017-8
2. 2. Trauma can cause cognitive symptoms even when you're NOT thinking about the traumatic event. Concentration failure, memory problems, difficulty planning - these are trauma effects, not laziness or aging. The fog IS the trauma. Source: DSM-5 PTSD criteria; clinical consensus
3. 3. THE HYPERVIGILANCE CHECK: Are you constantly scanning for threats? Tense even when 'relaxing'? Startling easily? Sitting with your back to the wall? This hypervigilance is cognitively exhausting. It's why there's nothing left for thinking. Source: Clinical pattern recognition
4. 4. 'It wasn't bad enough to be trauma' is the most common barrier to treatment. Trauma is defined by your nervous system's response, not by whether others would consider it severe. If your body is reacting as if threatened, that's trauma. Source: Van der Kolk; trauma-informed care principles
5. 5. THE BODY INVENTORY: Right now, scan your body. Where do you hold tension? Jaw clenched? Shoulders high? Stomach tight? Trauma is stored in the body. Chronic muscular tension is a trauma signature. Source: van der Kolk, The Body Keeps the Score
6. 6. EMDR (Eye Movement Desensitization and Reprocessing) can process trauma faster than traditional talk therapy - often 6-12 sessions. It sounds strange (bilateral stimulation while processing memories), but the evidence is strong. NICE recommends it first-line. Source: NICE NG116 PTSD
7. 7. THE GROUNDING TEST: When triggered, try 5-4-3-2-1: Name 5 things you see, 4 you hear, 3 you feel, 2 you smell, 1 you taste. This activates the present moment and interrupts trauma responses. Practice it now so it's available when needed. Source: Clinical grounding techniques
8. 8. Not all therapists are trained in trauma. General talk therapy without proper techniques can actually retraumatize. Ask specifically: 'Are you trained in EMDR or trauma-focused CBT?' If not, find someone who is. Source: NICE NG116 PTSD
9. 9. Write this down for your GP: 'I have experienced traumatic events and am having cognitive symptoms. I'd like a referral to a trauma-specialized therapist for evaluation. I'm interested in EMDR or trauma-focused CBT.' Source: Clinical guidance
10. 10. THE BODY SCAN: When fog descends, pause and scan your body. Where's the tension? Jaw clenched? Shoulders up? Stomach tight? Trauma lives in the body, not just the mind. Noticing WHERE you hold stress helps somatic therapies work faster. Source: van der Kolk; Somatic Experiencing approach
11. 11. Physical symptoms often accompany trauma: chronic pain, fatigue, GI issues, tension headaches. These often improve alongside cognitive symptoms when trauma is processed. Your body holds the trauma too. Source: van der Kolk, The Body Keeps the Score
12. 12. THE COLD WATER RESET: For acute overwhelm, splash cold water on your face. This activates the dive reflex and interrupts the trauma response. It's a physiological reset you can do anywhere. Source: Vagal nerve activation; clinical techniques
13. 13. Integration is possible. Healing doesn't mean forgetting - it means the past stops hijacking the present. Many people report their thinking becomes clearer, faster, more flexible after processing trauma. The cognitive resources you're using for survival become available for living.

Quick Win

If you suspect trauma is affecting your cognition: find a trauma-informed therapist (not just any therapist). EMDR and trauma-focused CBT are evidence-based treatments. The fog often lifts as trauma is processed.

• Cost: $$-$$$ (therapy costs; some covered by insurance)
• Time to effect: EMDR: 6-12 sessions. Trauma-focused CBT: 12-16 sessions. Improvement can begin within weeks.

Interventions

Lifestyle

• Establish Safety
  Ensure current environment is safe. Trauma processing works best when you're not currently under threat.
  Mechanism: The nervous system cannot process past trauma while current threats are active.
  Evidence: Strong - clinical consensus
  Cost: Free (may require practical support)
• Nervous System Regulation
  Practices that calm the nervous system: slow breathing, nature exposure, gentle movement, cold water on face, safe social connection.
  Mechanism: Trauma keeps the nervous system in fight/flight. Regulation practices help restore balance.
  Evidence: Moderate
  Cost: Free
• Grounding Techniques
  When triggered: 5-4-3-2-1 technique, strong sensory input (cold, strong tastes), naming present-moment objects.
  Mechanism: Grounding activates the present moment and interrupts trauma responses.
  Evidence: Moderate - clinical consensus
  Cost: Free

Investigation

• Trauma Assessment
  • ACE (Adverse Childhood Experiences) questionnaire
  • Clinical interview with trauma-informed provider
  • Rule out medical causes (thyroid, B12, etc.)
  
  Interpretation: High ACE scores are associated with numerous health outcomes including cognitive difficulties. Trauma assessment helps guide treatment.
  Cost: Free-$

Medical

• EMDR (Eye Movement Desensitization and Reprocessing)
  6-12 sessions with EMDR-trained therapist. Uses bilateral stimulation while processing traumatic memories.
  Evidence: Strong - NICE recommended
  Note: Often works faster than traditional talk therapy for processing trauma.
• Trauma-Focused CBT
  12-16 sessions with trauma-trained therapist. Includes exposure therapy and cognitive restructuring.
  Evidence: Strong - NICE recommended
  Note: Specifically designed for trauma. Different from general CBT.
• Somatic Therapies
  Body-based approaches like Somatic Experiencing, Sensorimotor Psychotherapy.
  Evidence: Moderate - emerging evidence, strong clinical support
  Note: Work with the body's stored trauma. Can complement or precede cognitive approaches.
• Medication (if indicated)
  SSRIs can help manage symptoms. Not curative but may support therapy work.
  Evidence: Moderate
  Note: Medication can help stabilize while doing therapy work.

Supplements

• Magnesium glycinate
  Dose: 200-400mg before bed
  May support nervous system regulation and sleep. Supportive, not treatment.

Support This Week

• Body: Gentle, regulating movement: walking, stretching, gentle yoga. Avoid intense exercise if it triggers anxiety.
• Food: Regular meals. Protein for stability. Limit caffeine if anxious.
• Water: Stay hydrated. Sipping water can be grounding.
• Environment: Create a safe space at home. Notice what helps you feel safe.
• Connection: Trusted people are essential for trauma recovery. Don't isolate.
• Tracking: Track triggers and what helps. This information is valuable for therapy.
• Avoid: Don't try to process alone. Don't use alcohol to cope. Don't isolate.

Dietary Pattern

Nervous System Support

Regular meals and stable blood sugar support nervous system regulation.

Core: Regular meals, don't skip. Protein at each meal. Limit caffeine and alcohol. Anti-inflammatory foods.

Caffeine can worsen hypervigilance. Alcohol disrupts sleep and nervous system. Regular, nourishing meals support regulation.

Community Insights

What Helped

• Finding a TRAUMA-trained therapist - not just any therapist
• EMDR - processed things that years of talk therapy didn't touch
• Learning that trauma is physiological, not just 'in my head'
• Grounding techniques for acute moments

What Didn't Help

• Talk therapy without trauma training - talking about it without processing can retraumatize
• Trying to think my way out of it - trauma is stored in the body
• Pushing through - needed to work WITH my nervous system

Surprises

• The fog lifted as trauma was processed - they were connected
• Childhood experiences I thought were 'normal' counted as trauma
• Body-based approaches worked when cognitive approaches hadn't

Common Mistakes

• Seeing a therapist not trained in trauma - specific training matters
• Thinking it 'wasn't bad enough' to be trauma
• Trying to process trauma before establishing safety

Tip: Trauma isn't just the dramatic events - chronic stress, neglect, and adverse childhood experiences count. The fog is your nervous system's protection mode consuming all your cognitive resources. Trauma-specific therapy (EMDR, TF-CBT) helps your brain process what it's been holding, and the fog often lifts naturally.

Holistic Support

• Trauma-trained therapy
  Evidence: Strong - specific trauma training matters
  How: Find a therapist trained in EMDR, TF-CBT, or somatic approaches. Ask about their trauma training.
• Nervous system regulation
  Evidence: Moderate - supports therapy work
  How: Breathing practices, nature exposure, safe social connection, body-based practices.

Safety Notes

• Driving: Trauma can cause dissociation, flashbacks, or concentration difficulties that may affect driving. If experiencing these symptoms, consider alternatives until treated.
• Work: Hypervigilance, concentration difficulties, and emotional dysregulation can affect work. Trauma is a disability under Equality Act (UK) and ADA (US) - reasonable adjustments may be available.
• Pregnancy: Pregnancy can trigger past trauma, especially birth-related or sexual trauma. Inform midwife/OB of trauma history. Trauma-focused therapy is safe and often beneficial during pregnancy. SSRIs if needed should be discussed with OB.

Why These Causes Connect
