Trauma, whether it's from an accident, violence, or any other distressing experience, can have a profound impact on the brain's structure and function. Not only is it a distressing experience in the moment and provide fearful memories that can change your behavior in future, but when someone experiences trauma, their brain reacts in ways that are crucial for survival but can lead to long-lasting effects.

According to The Mayo Clinic:

Traumatic brain injury usually results from a violent blow or jolt to the head or body. An object that goes through brain tissue, such as a bullet or shattered piece of skull, also can cause traumatic brain injury.

Mild traumatic brain injury may affect your brain cells temporarily. More-serious traumatic brain injury can result in bruising, torn tissues, bleeding and other physical damage to the brain. These injuries can result in long-term complications or death.

Here are three ways trauma affects the brain and a person's behavior. It is useful to be aware as you, or someone you know, may experience a traumatic brain injury at some point in their life:

The Brain's Response to Trauma

1. Fight-or-Flight Activation: During traumatic events, the brain's amygdala triggers a fight-or-flight response. This mechanism is vital for survival, helping individuals react quickly to danger. However, repeated activation can lead to heightened anxiety and hypervigilance, where the brain constantly anticipates threats even when none exist. It means they may live at a heightened level of anxiety which causes them to be fearful of taking part in many activities and become more risk averse. 

2. Impact on Memory and Cognition: Trauma can disrupt the hippocampus, the area of the brain responsible for forming and retrieving memories. This disruption can result in fragmented or distorted memories of the traumatic event, making it difficult for individuals to process what happened. They might have gaps in their memory which can be distressing to experience.

3. Long-term Emotional Effects: The prefrontal cortex, which governs rational thinking and decision-making, can also be affected by trauma. This can lead to difficulties in regulating emotions, managing stress, and making decisions, often manifesting in conditions such as PTSD (Post-Traumatic Stress Disorder). So be kind and patient with those who have experienced a traumatic brain injury. They're trying the best they can which may look different to what it used to be.

Healing the Brain After Trauma

Recovery from trauma is possible, but it often requires professional support. Various therapeutic approaches, including cognitive-behavioral therapy (CBT) and EMDR (Eye Movement Desensitization and Reprocessing), have been shown to help individuals process their trauma and begin the healing journey. Additionally, self-care practices like mindfulness and regular physical activity can support the brain's recovery process.
