Trauma can lead to several physiological changes, such as changes in brain wave patterns and an increase in stress hormone activity. These changes are the result of the brain’s attempt to protect itself from further harm. However, they can also lead to several problems, including anxiety. Trauma changes the way a person experiences the world. It recalibrates the brain’s alarm system, increasing a person’s vigilance to threat at the expense of spontaneous engagement in daily life.
- This can make even minor irritations feel like threats, triggering a fight, flight, or freeze response.
- The body’s response to the trauma becomes the problem more than the trauma itself.
- These responses are not the result of moral failings or lack of willpower, but are caused by actual changes in the brain.
- Trauma can also lead to problems with self-regulation and the capacity to stay focused.
- Trauma survivors may blank out or dissociate in response to reminders of past trauma.
The Role of the Amygdala
The amygdala is a small almond-shaped structure in the brain that plays a critical role in fear and anxiety. It is responsible for attaching emotional significance to situations and forming emotional memories, both positive and negative.
- When something triggers the amygdala, it activates the stress response, leading to a variety of physical and emotional reactions, including anxiety.
- Traumatic experiences can sensitize the amygdala, making it more likely to react to perceived threats.
- This is why trauma survivors may experience anxiety even in situations that are not objectively dangerous.
- The amygdala can learn to associate certain triggers with danger, even if the trigger is not inherently dangerous. For example, a person who has been in a car accident may develop anxiety when they smell the cologne they was wearing, even though cologne is not inherently dangerous. This is because the amygdala has learned to associate the smell of cologne with the car accident.
The Role of the Cortex
The cortex is the outer layer of the brain that is responsible for higher-level thinking, planning, and decision-making. It also plays a role in anxiety, by interpreting situations as threatening and sending messages to the amygdala that trigger a fear response. The cortex can create unnecessary anxiety and worsen anxiety that originates in the amygdala. The cortex can contribute to anxiety in several ways, including:
- Overthinking: When people overthink, they tend to focus on the worst-case scenario, which can increase anxiety.
- Negative interpretations: The cortex can interpret situations in a negative light, even if there is no evidence to support that interpretation.
- Rumination: Rumination is the act of dwelling on negative thoughts and experiences, which can fuel anxiety.
- Worry: Worry is a form of anticipatory anxiety that involves thinking about potential threats or problems.
The cortex and amygdala work together to create anxiety. The cortex interprets situations as threatening, and the amygdala triggers the fear response.
Other Factors That Contribute to Trauma-Related Anxiety
In addition to the amygdala and cortex, other factors can contribute to trauma-related anxiety:
- Genetics: Some people are genetically predisposed to anxiety.
- Early childhood experiences: Traumatic experiences in childhood, such as abuse or neglect, can increase the risk of developing anxiety disorders later in life.
- Learned responses: People can learn to be anxious by observing others’ anxious responses, particularly those of their parents or caregivers.
- Environmental factors: Stressful life events, such as job loss or divorce, can trigger anxiety in those who are already vulnerable.
- Avoidance: Avoiding situations that trigger anxiety can actually make anxiety worse in the long run, because it prevents people from learning that the feared situation is not actually dangerous.
How Trauma is Encoded as Memory
Traumatic memories are stored in the brain differently from ordinary memories. While ordinary memories are semantic and symbolic, and can change over time, traumatic memories are vivid, sensory-based, and feel as if they are happening in the present moment. This is because the amygdala, which is responsible for emotional memories, is highly activated during a traumatic event.
- When the amygdala is activated, it releases stress hormones, such as cortisol and norepinephrine, which help to consolidate the memory.
- The high levels of stress hormones also interfere with the hippocampus, which is responsible for encoding memories in a way that can be accessed consciously.
- This is why traumatic memories are often fragmented and difficult to recall in a linear way.
The Cycle of Trauma and Anxiety
Trauma and anxiety can create a vicious cycle. Trauma can lead to anxiety, and anxiety can make it more difficult to cope with trauma. For example:
- A person who has experienced trauma may avoid situations that remind them of the trauma, which can limit their lives and make them feel more isolated.
- Anxiety can also lead to physical symptoms, such as muscle tension, headaches, and fatigue, which can further reduce a person’s ability to cope with trauma.
- This cycle can be difficult to break, but with the right treatment and support, it is possible to heal from trauma and reduce anxiety.
Overcoming Trauma-Related Anxiety
While trauma can have a lasting impact on a person’s life, it is important to remember that healing is possible. There are a variety of effective treatments for trauma-related anxiety, including:
- Therapy: Therapy can help people to process their trauma, develop coping skills, and change negative thought patterns. There are many different types of therapy that can be helpful for trauma, such as Acceptance and Commitment therapy (ACT), Havening, NLP, Solution focused therapy, eye movement desensitization and reprocessing (EMDR), and somatic experiencing.
- Medications: Medications, such as antidepressants and anti-anxiety medications, can help to reduce the symptoms of anxiety and make it easier to engage in therapy.
- Lifestyle changes: Lifestyle changes, such as exercise, relaxation techniques, and getting enough sleep, can also help to reduce anxiety.
- Self-help strategies: There are a number of self-help strategies that can be helpful for coping with anxiety, such as mindfulness, journaling, and spending time in nature.
It is important to find a therapist who is experienced in treating trauma. A good therapist will help you to feel safe and supported as you work through your trauma.
