A psychoanalyst is a mental health professional who specializes in the practice of psychoanalysis. Psychoanalysis is a form of psychotherapy that focuses on exploring the unconscious mind and understanding how it affects behavior. It is based on the theories of Sigmund Freud, who believed that unconscious desires and conflicts can influence behavior. The psychoanalyst helps the patient to gain insight into their unconscious thoughts and feelings, and to develop healthier ways of coping with life's challenges.
