According to the American Psychological Association (APA), research shows that most people who receive psychotherapy experience symptom relief and are better able to function in their lives. About 75% of people who enter psychotherapy show some benefit from it.
Psychotherapy has been shown to improve emotions and behaviors. It is also linked with positive changes in the brain and body. The benefits include: fewer sick days, less disability, fewer medical problems, and an increased satisfaction with life.
Psychotherapy literally changes the structure and the functioning of the brain. Now with the use of brain imaging techniques researchers have been able to see changes in the brain after a person has undergone psychotherapy. Numerous studies have identified brain changes in people with mental illness (including depression, panic disorder, PTSD and other conditions) as a result of undergoing psychotherapy. In most cases the brain changes resulting from psychotherapy were similar to changes resulting from medication.

To help get the most out of psychotherapy, the best way to approach the therapy is as a collaborative effort. Be open and honest, and follow your agreed upon plan for treatment.
