“What is psychotherapy for PTSD?”

Psychotherapy Also known as talk therapy, psychotherapy is a common non-medicinal treatment of many mental and emotional illnesses. Talking through the trauma helps control or eliminates the symptoms of PTSD.

Psychotherapy is the use of psychological methods, particularly when based on regular personal interaction, to help a person change behavior and overcome problems in desired ways. Psychotherapy aims to improve an individual's well-being and mental health, and to resolve or mitigate troublesome behaviors.

When someone experiences a traumatic event, symptoms are not necessarily going to disappear merely because the event is in the past. Especially if the event was particularly traumatic and the person did not deal with the emotional effects, the memories and the impact can linger and get "stuck" in the person. The symptoms will get expressed in various ways such as insomnia, nightmares, flashbacks, anger, apathy, and perhaps the use of drugs to cope. Psychotherapy is treatment to help support a person to heal from the trauma and there are many types of therapy that can do this. Personally, I work from a cognitive behavioral model and somer of the methods I use are cognitive restructuring, exposure therapy and grounding/mindfulness-based techniques. There are others methods such as EMDR.

There are many types of psychotherapy that can be used for treating PTSD. Some include coping skill development to manage symptoms, psychoeducation of the impact of trauma on the self, especially on brain functioning, trauma focused CBT, and EMDR to name a few. These methods are often combined with support and active listening, to enable clients to process and release their stories.
