Major depressive disorder (MDD), also known simply as depression, is a mental disorder characterized by at least two weeks of pervasive low mood. Low self-esteem, loss of interest in normally enjoyable activities, low energy, and pain without a clear cause are common symptoms. Those affected may also occasionally have delusions or hallucinations. Some people have periods of depression separated by years, while others nearly always have symptoms present. Major depression is more severe and lasts longer than sadness, which is a normal part of life.
The Diagnostic and Statistical Manual of Mental Disorders is a publication by the American Psychiatric Association (APA) for the classification of mental disorders using a common language and standard criteria.
A mental disorder, also called a mental illness or psychiatric disorder, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. Such features may be persistent, relapsing and remitting, or occur as a single episode. Many disorders have been described, with signs and symptoms that vary widely between specific disorders. Such disorders may be diagnosed by a mental health professional.
Psychiatric hospitals, also known as mental health units or behavioral health units, are hospitals or wards specializing in the treatment of serious mental disorders, such as major depressive disorder, schizophrenia and bipolar disorder. Psychiatric hospitals vary widely in their size and grading. Some hospitals may specialize only in short-term or outpatient therapy for low-risk patients. Others may specialize in the temporary or permanent containment of patients who need routine assistance, treatment, or a specialized and controlled environment due to a psychological disorder. Patients often choose voluntary commitment, but those whom psychiatrists believe to pose significant danger to themselves or others may be subject to involuntary commitment and involuntary treatment. Psychiatric hospitals may also be called psychiatric wards/units when they are a subunit of a regular hospital.
Historically, mental disorders have had three major explanations, namely, the supernatural, biological and psychological models. For much of recorded history, deviant behavior has been considered supernatural and a reflection of the battle between good and evil. When confronted with unexplainable, irrational behavior and by suffering and upheaval, people have perceived evil. In fact, in the Persian Empire from 550 to 330 B.C., all physical and mental disorders were considered the work of the devil. Physical causes of mental disorders have been sought in history. Hippocrates was important in this tradition as he identified syphilis as a disease and was therefore an early proponent of the idea that psychological disorders are biologically caused. This was a precursor to modern psycho-social treatment approaches to the causation of psychopathology, with the focus on psychological, social and cultural factors. Well known philosophers like Plato, Aristotle etc., wrote about the importance of fantasies, dreams, and thus anticipated, to some extent, the fields of psychoanalytic thought and cognitive science that were later developed. They were also some of the first to advocate for humane and responsible care for individuals with psychological disturbances.

Care Programme Approach (CPA) in the United Kingdom is a system of delivering community mental health services to individuals diagnosed with a mental illness. It was introduced in England in 1991 and by 1996 become a key component of the mental health system in England. The approach requires that health and social services assess need, provided a written care plan, allocate a care coordinator, and then regularly review the plan with key stakeholders, in keeping with the National Health Service and Community Care Act 1990.
The Critical Psychiatry Network (CPN) is a psychiatric organization based in the United Kingdom. It was created by a group of British psychiatrists who met in Bradford, England in January 1999 in response to proposals by the British government to amend the 1983 Mental Health Act (MHA). They expressed concern about the implications of the proposed changes for human rights and the civil liberties of people with mental health illness. Most people associated with the group are practicing consultant psychiatrists in the United Kingdom's National Health Service (NHS), among them Dr Joanna Moncrieff. A number of non-consultant grade and trainee psychiatrists are also involved in the network.
The fall of the lunatic asylum and its gradual transformation into, and eventual replacement by, the modern psychiatric hospital, explains the rise of organized, institutional psychiatry. While there were earlier institutions that housed the "insane", the conclusion that institutionalization was the correct solution to treating people considered to be "mad" was part of a social process in the 19th century that began to seek solutions for outside families and local communities.

Psychiatry is, and has historically been, viewed as controversial by those under its care, sociologists and psychiatrists themselves. Reasons cited for this controversy include the subjectivity of diagnosis, the use of diagnosis and treatment for social and political control including detaining citizens and treating them without consent, and the side effects of treatments like electroconvulsive therapy, antipsychotics and historical procedures like lobotomy and other forms of psychosurgery or insulin shock therapy.
William Hunter CB FRSE was a British surgeon known primarily for his theories on oral sepsis, one of the inspirations for the Henry Cotton theory of focal sepsis which led to the increased number of tooth extractions and tonsillectomies in the 1910s and 20s. By the 1930s, this view had fallen out of favor, but not until after thousands of surgeries had been performed.
