Psychoanalysis is a therapeutic method and field of research developed by Sigmund Freud. Founded in the early 1890s, initially in co-operation with Josef Breuer and others' clinical research, he continued to refine and develop theory and practice of psychoanalysis until his death in 1939. It conceptualizes the human psyche as consisting of three primary instances: the id, the ego, and the superego, which interact to satisfy the instinctive needs. Creation and transmission of civilisation serves this biological processes of self-preservation and reproduction.
Psychotherapy is the use of psychological methods, particularly when based on regular personal interaction, to help a person change behavior, increase happiness, and overcome problems. Psychotherapy aims to improve an individual's well-being and mental health, to resolve or mitigate troublesome behaviors, beliefs, compulsions, thoughts, or emotions, and to improve relationships and social skills. Numerous types of psychotherapy have been designed either for individual adults, families, or children and adolescents. Some types of psychotherapy are considered evidence-based for treating diagnosed mental disorders; other types have been criticized as pseudoscience.
Neurosis is a term mainly used today by followers of Freudian thinking to describe mental disorders caused by past anxiety, often that has been repressed. In recent history, the term has been used to refer to anxiety-related conditions more generally.
Narcissistic personality disorder (NPD) is a personality disorder characterized by a life-long pattern of exaggerated feelings of self-importance, an excessive need for admiration, and a diminished ability to empathize with other people's feelings. Narcissistic personality disorder is one of the sub-types of the broader category known as personality disorders. It is often comorbid with other mental disorders and associated with significant functional impairment and psychosocial disability.
Abnormal psychology is the branch of psychology that studies unusual patterns of behavior, emotion, and thought, which could possibly be understood as a mental disorder. Although many behaviors could be considered as abnormal, this branch of psychology typically deals with behavior in a clinical context. There is a long history of attempts to understand and control behavior deemed to be aberrant or deviant, and there is often cultural variation in the approach taken. The field of abnormal psychology identifies multiple causes for different conditions, employing diverse theories from the general field of psychology and elsewhere, and much still hinges on what exactly is meant by "abnormal". There has traditionally been a divide between psychological and biological explanations, reflecting a philosophical dualism in regard to the mind–body problem. There have also been different approaches in trying to classify mental disorders. Abnormal includes three different categories; they are subnormal, supernormal and paranormal.
The field of psychology has extensively studied homosexuality as a human sexual orientation. The American Psychiatric Association listed homosexuality in the DSM-I in 1952 as a "sociopathic personality disturbance," but that classification came under scrutiny in research funded by the National Institute of Mental Health. That research and subsequent studies consistently failed to produce any empirical or scientific basis for regarding homosexuality as anything other than a natural and normal sexual orientation that is a healthy and positive expression of human sexuality. As a result of this scientific research, the American Psychiatric Association removed homosexuality from the DSM-II in 1973. Upon a thorough review of the scientific data, the American Psychological Association followed in 1975 and also called on all mental health professionals to take the lead in "removing the stigma of mental illness that has long been associated" with homosexuality. In 1993, the National Association of Social Workers adopted the same position as the American Psychiatric Association and the American Psychological Association, in recognition of scientific evidence. The World Health Organization, which listed homosexuality in the ICD-9 in 1977, removed homosexuality from the ICD-10 which was endorsed by the 43rd World Health Assembly on 17 May 1990.
Dissociation is a concept that has been developed over time and which concerns a wide array of experiences, ranging from a mild emotional detachment from the immediate surroundings, to a more severe disconnection from physical and emotional experiences. The major characteristic of all dissociative phenomena involves a detachment from reality, rather than a false perception of reality as in psychosis.
Psychodynamic psychotherapy and psychoanalytic psychotherapy are two categories of psychological therapies. Their main purpose is revealing the unconscious content of a client's psyche in an effort to alleviate psychic tension, which is inner conflict within the mind that was created in a situation of extreme stress or emotional hardship, often in the state of distress. The terms "psychoanalytic psychotherapy" and "psychodynamic psychotherapy" are often used interchangeably, but a distinction can be made in practice: though psychodynamic psychotherapy largely relies on psychoanalytical theory, it employs substantially shorter treatment periods than traditional psychoanalytical therapies. Psychodynamic psychotherapy is evidence-based; the effectiveness of psychoanalysis and its relationship to facts is disputed.
Biological psychiatry or biopsychiatry is an approach to psychiatry that aims to understand mental disorder in terms of the biological function of the nervous system. It is interdisciplinary in its approach and draws on sciences such as neuroscience, psychopharmacology, biochemistry, genetics, epigenetics and physiology to investigate the biological bases of behavior and psychopathology. Biopsychiatry is the branch of medicine which deals with the study of the biological function of the nervous system in mental disorders.

Energy is a concept in some psychological theories or models of a postulated unconscious mental functioning on a level between biology and consciousness.
Child psychotherapy, or mental health interventions for children refers to the psychological treatment of various mental disorders diagnosed in children and adolescents. The therapeutic techniques developed for younger age ranges specialize in prioritizing the relationship between the child and the therapist. The goal of maintaining positive therapist-client relationships is typically achieved using therapeutic conversations and can take place with the client alone, or through engagement with family members.
The Austen Riggs Center is a psychiatric treatment facility located in Stockbridge, Massachusetts. It was founded in 1913 as the Stockbridge Institute for the Study and Treatment of Psychoneuroses by Austen Fox Riggs. The institution was renamed in his honor on July 21, 1919.
Psychoanalytic dream interpretation is a subdivision of dream interpretation as well as a subdivision of psychoanalysis pioneered by Sigmund Freud in the early 20th century. Psychoanalytic dream interpretation is the process of explaining the meaning of the way the unconscious thoughts and emotions are processed in the mind during sleep.
Although modern, scientific psychology is often dated from the 1879 opening of the first psychological clinic by Wilhelm Wundt, attempts to create methods for assessing and treating mental distress existed long before. The earliest recorded approaches were a combination of religious, magical and/or medical perspectives. Early examples of such psychological thinkers included Patañjali, Padmasambhava, Rhazes, Avicenna and Rumi.
