Neurologist
Sigmund Freud is credited with developing this early method of
psychotherapy based on his theories of
neurosis arising out of
psychosexual development in childhood and resulting
intrapsychic conflict.
Psychoanalysts, who may be
psychiatrists,
psychologists, social workers or other professionals, treat their patients by techniques involving achievement of insight, working through,
interpretation of dream material, and understanding transference and
resistance to change.
