Psychotherapy or talk therapy, is a way to help people with a broad variety of mental illnesses and emotive difficulties. Psychotherapy can help reject or control upsetting symptoms so a person can function better and can increase well-being and healing. Psychotherapy is a collective treatment based on the relationship between an individual and a psychologist. Grounded in dialogue, it provides a supportive environment that allows you to talk openly with someone who’s objective, neutral and non-judgmental. With the use of brain imaging techniques researchers have been able to see changes in the brain after a person has undergone psychotherapy.
