Hypnotherapy, which is basically the use of hypnosis in a therapeutic setting, is not without controversy. Some professionals use it to treat everything from depression to posttraumatic stress disorder, especially in people who are not responding to drug treatment or in those who are looking for a complementary form of therapy. The system is also used to access repressed memories, especially in abuse cases, although psychologists believe there is a high risk that the mind will create false memories or scenarios to fill in the blanks.
