How does trauma affect the brain?

Trauma can affect memory, responses to threat and daily functioning. It is more useful to discuss connected brain systems than to say there is one place where trauma is kept. Brain research does not provide a simple test that proves a particular event occurred.

People’s experiences and recovery differ. Treatment can help reduce the impact of trauma, but a promise to rewire the brain is not a precise description of an individual outcome.

The Brain Structures Involved in Trauma

The amygdala, hippocampus and prefrontal cortex are among the regions studied in relation to emotion, memory and responses to threat. They operate within connected systems rather than as separate containers for trauma. Research findings across groups should not be treated as a diagnosis of one person.

How Do Brain Systems Contribute to Remembering Trauma?

Remembering an event involves multiple processes and brain systems. A vivid memory, a fragmentary memory and a gap in recall each require context; none establishes one universal storage mechanism. A physical sensation is not a verified record of what happened.

How Does Trauma Affect Memory?

Stress and trauma can be associated with memory difficulties, but experiences vary. Changes in concentration, sleep and other health factors may also affect recall. Do not assume that incomplete recall establishes hidden trauma or that therapy can certify a recovered memory. See the APA’s discussion of trauma and memory.

How Does Trauma Physically Impact the Brain?

Studies of brain structure and function report findings across participants. They do not show that every person has the same changes or that a symptom identifies a damaged region. Physical symptoms deserve appropriate assessment rather than an assumed neurological explanation.

The Role of Therapy in Trauma Recovery

If you have experienced trauma, therapy can be an effective way to process and manage the impact of the experience. Different types of therapy can be used to help individuals recover from trauma. Here are some of the most common types of therapy used in trauma recovery:

 

Cognitive Processing Therapy (CPT)

Cognitive Processing Therapy (CPT) is a type of cognitive-behavioral therapy that focuses on helping individuals identify and challenge negative thoughts and beliefs related to their trauma. CPT can help you develop coping skills to manage the symptoms of trauma, such as anxiety and depression. It can also help you develop a better understanding of the impact of trauma on your life.

 

Eye Movement Desensitization and Reprocessing (EMDR)

Eye Movement Desensitization and Reprocessing (EMDR) is a type of therapy that uses eye movements or other forms of bilateral stimulation to help individuals process traumatic memories. EMDR can help reduce the intensity of traumatic memories and the associated emotional distress.

 

Somatic Therapy

Somatic therapy is a type of therapy that focuses on the connection between the mind and body. Somatic therapy can help individuals identify and release physical tension and sensations related to their trauma. It can also help individuals develop a greater sense of control over their physical and emotional responses to trauma.

 

Prolonged Exposure Therapy

Prolonged Exposure Therapy is a type of therapy that involves gradually exposing individuals to the memories and situations that trigger their trauma. This exposure can help individuals learn to manage their symptoms and develop a greater sense of control over their lives.

 

The Future of Trauma Research

Research continues to investigate trauma-related symptoms and treatment. Proposed mechanisms should be distinguished from demonstrated benefits. For information about care, visit our PTSD treatment center page.
