Understanding the Impact: 6 Ways Trauma Affects Your Brain

Updated: Feb 14


Ever feel like your brain just doesn't work the way it used to after a tough experience? Did you know that trauma leaves a real mark, not just on our hearts but on our very brains? 🧠

Let's explore what's going on upstairs.


Trauma Affects Your Brain


A Startling Truth from PET Scans


PET scans offer us a window into our brain's response to trauma.

A glimpse through the lens of a PET scan reveals how trauma changes the brain, leading to high activity in areas responsible for survival. This shift explains so much of the trauma experience.


Survival activity will include impulsive reactions, emotional drowsiness or over-sensitivity, difficulty finding pleasure in life activities and relationships, changes in sleeping and eating habits, and more.


Here are two brain scans side by side: on the left, a healthy brain showing balanced activity; on the right, a trauma survivor's brain, with heightened activity in the back and less in areas responsible for social interactions and higher functions like concentration. This reshaping is more than ordinary; it's a testament to our unseen battles.



1. Alert Overdrive

In the wake of trauma, one specific and intense response is the hyperactivation of the brain's alert system. This is a critical aspect of the trauma response, focusing on heightened vigilance. Imagine your brain's alarm system stuck in overdrive. It's as if your mind is constantly on high alert, overly sensitive to even minor noises or potential threats. This state leads to an ongoing sense of anxiety and an inability to relax, as you're always prepared for possible danger.


This perpetual state of alertness is not just mentally taxing; it also takes a physical toll. It's like being in a constant state of emergency, which can be exhausting both mentally and physically, leaving little room for rest or recuperation.




2. Memory Mix-Ups

Ever walked into a room and forgot why? That's trauma scrambling your hippocampus, your brain's memory manager, causing repetitive memories or gaps.

Trauma can cause the hippocampus to falter in organizing memories. You might experience intrusive flashbacks or struggle to remember recent events. This disorganization in memory processing can make it difficult to distinguish between past and present threats, adding to feelings of confusion and distress.

3. Decision-Making Glitches

After experiencing trauma, the process of making decisions can often seem perplexing. The prefrontal cortex, which plays a crucial role in decision-making and judgment, may not function as efficiently as it used to. This can make even routine daily decisions more challenging, affecting everything from minor everyday choices to significant, life-altering decisions




4. Focus Fades

Concentration can be as challenging as reading in low light. It's not that the ability to focus has been lost entirely, but rather, it's akin to a lamp with a weakened bulb.

The light – your focus – is still present, yet it requires more effort to illuminate the pages of your tasks and thoughts. This reduced clarity in concentration can lead to easily being sidetracked, a slower processing speed, and difficulty in maintaining attention on a single task for extended periods. Tasks that once seemed effortless may now require substantial mental exertion, as if you're trying to see through a fog.


This can be particularly noticeable in environments with multiple stimuli or when handling complex or new tasks, where the brain's diminished focus ability struggles to keep up with the demands, making everyday activities more challenging and taxing.

5. Social Signal Dropouts

Connecting with people might get tougher.  Imagine your brain's ability to interpret and respond to social cues as a network signal. Trauma can cause this signal to become erratic and unreliable, akin to having a poor reception on a mobile phone.


Conversations that once flowed effortlessly might now feel cumbersome, as if you're trying to communicate through a static-filled line. This can lead to misunderstandings or missing subtle emotional cues in others, making social interactions more challenging.


Furthermore, this disrupted 'social reception' might make it harder to express your own feelings and thoughts clearly, adding to the sense of disconnection. The usual give-and-take of social interactions may feel overwhelming or exhausting, as if every conversation requires more effort to maintain a clear connection. This difficulty in social engagement can foster feelings of isolation and loneliness, even when surrounded by people. It's not just about struggling to connect with others but also about feeling disconnected from the social world itself, as if you're observing it from behind a barrier of interference.

6. Energy Dips

Following a traumatic event, there's a more comprehensive impact on an individual's overall energy levels. Your inner battery may drain quicker as your body's stress response works overtime, causing fatigue and exhaustion. It's not just about being in a state of heightened alertness; it's about how this constant stress response consumes substantial energy.

These energy dips have practical implications in daily life. They manifest as a need for more rest, yet often, one wakes up feeling unrefreshed. Patience and the ability to cope with stress are reduced, and activities that used to be rejuvenating may now seem too demanding. It’s a cycle where the battery of resilience and energy struggles to recharge effectively, leading to a persistent state of running low on energy.


Emotional Well-being


Transforming Trauma into Growth

Grasping the nuances of these changes is fundamental. The focus isn't on lingering in the past but rather on shedding light on the way forward. Envisioning this transition as a journey from the shadows into the light, from chaos to calm, is essential for the healing process.

This understanding forms the cornerstone of my practice as a psychophysiological therapist. It's a perspective that not only guides my therapeutic approach but also serves as the core inspiration for my book, 'The Phoenix Awakening'. In this work, I delve into how acknowledging and working through these changes can be a transformative experience, leading one towards renewal and peace.
