A mental disorder, also referred to as a mental illness or psychiatric disorder, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. A mental disorder is also characterized by a clinically significant disturbance in an individual's cognition, emotional regulation, or behavior. It is usually associated with distress or impairment in important areas of functioning. There are many different types of mental disorders. Mental disorders may also be referred to as mental health conditions. Such features may be persistent, relapsing and remitting, or occur as single episodes. 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, usually a clinical psychologist or psychiatrist.
Psychiatric hospitals, also known as mental health hospitals or behavioral health hospitals, are hospitals or wards specializing in the treatment of severe mental disorders, including schizophrenia, bipolar disorder, eating disorders, dissociative identity disorder, major depressive disorder, and others.
Anti-psychiatry, sometimes spelled antipsychiatry without the hyphen, is a movement based on the view that psychiatric treatment is often more damaging than helpful to patients, highlighting controversies about psychiatry. Objections include the reliability of psychiatric diagnosis, the questionable effectiveness and harm associated with psychiatric medications, the failure of psychiatry to demonstrate any disease treatment mechanism for psychiatric medication effects, and legal concerns about equal human rights and civil freedom being nullified by the presence of diagnosis. Historical critiques of psychiatry came to light after focus on the extreme harms associated with electroconvulsive therapy or insulin shock therapy. The term "anti-psychiatry" is in dispute and often used to dismiss all critics of psychiatry, many of whom agree that a specialized role of helper for people in emotional distress may at times be appropriate, and allow for individual choice around treatment decisions.
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.
Mental health encompasses emotional, psychological, and social well-being, influencing cognition, perception, and behavior. According to World Health Organization (WHO), it is a "state of well-being in which the individual realizes his or her abilities, can cope with the normal stresses of life, can work productively and fruitfully, and can contribute to his or her community". It likewise determines how an individual handles stress, interpersonal relationships, and decision-making. Mental health includes subjective well-being, perceived self-efficacy, autonomy, competence, intergenerational dependence, and self-actualization of one's intellectual and emotional potential, among others. From the perspectives of positive psychology or holism, mental health may include an individual's ability to enjoy life and to create a balance between life activities and efforts to achieve psychological resilience. Cultural differences, personal philosophy, subjective assessments, and competing professional theories all affect how one defines "mental health". Some early signs related to mental health difficulties are sleep irritation, lack of energy, lack of appetite, thinking of harming oneself or others, self-isolating, and frequently zoning out.
The Lanterman–Petris–Short (LPS) Act regulates involuntary civil commitment to a mental health institution in the state of California. The act set the precedent for modern mental health commitment procedures in the United States. The bipartisan bill was co-authored by California State Assemblyman Frank D. Lanterman (R) and California State Senators Nicholas C. Petris (D) and Alan Short (D), and signed into law in 1967 by Governor Ronald Reagan. The Act went into full effect on July 1, 1972. It cited seven articles of intent:
The Mental Health Act 1983 is an Act of the Parliament of the United Kingdom. It covers the reception, care and treatment of mentally disordered people, the management of their property and other related matters, forming part of the mental health law for the people in England and Wales. In particular, it provides the legislation by which people diagnosed with a mental disorder can be detained in a hospital or police custody and have their disorder assessed or treated against their wishes, informally known as "sectioning". Its use is reviewed and regulated by the Care Quality Commission. The Act was significantly amended by the Mental Health Act 2007. A white paper proposing changes to the act was published in 2021 following an independent review of the act by Simon Wessely.
Moral treatment was an approach to mental disorder based on humane psychosocial care or moral discipline that emerged in the 18th century and came to the fore for much of the 19th century, deriving partly from psychiatry or psychology and partly from religious or moral concerns. The movement is particularly associated with reform and development of the asylum system in Western Europe at that time. It fell into decline as a distinct method by the 20th century, however, due to overcrowding and misuse of asylums and the predominance of biomedical methods. The movement is widely seen as influencing certain areas of psychiatric practice up to the present day. The approach has been praised for freeing sufferers from shackles and barbaric physical treatments, instead considering such things as emotions and social interactions, but has also been criticised for blaming or oppressing individuals according to the standards of a particular social class or religion.
Deinstitutionalisation is the process of replacing long-stay psychiatric hospitals with less isolated community mental health services for those diagnosed with a mental disorder or developmental disability. In the late 20th century, it led to the closure of many psychiatric hospitals, as patients were increasingly cared for at home, in halfway houses and clinics, in regular hospitals, or not at all.
The psychiatric survivors movement is a diverse association of individuals who either currently access mental health services, or who have experienced interventions by psychiatry they consider unhelpful, harmful, abusive or illegal.
Intellectual disability (ID), also known as general learning disability in the United Kingdom and formerly mental retardation, is a generalized neurodevelopmental disorder characterized by significantly impaired intellectual and adaptive functioning. It is defined by an IQ under 70, in addition to deficits in two or more adaptive behaviors that affect everyday, general living. Intellectual functions are defined under DSM-V as reasoning, problem‑solving, planning, abstract thinking, judgment, academic learning, and learning from instruction and experience, and practical understanding confirmed by both clinical assessment and standardized tests. Adaptive behavior is defined in terms of conceptual, social, and practical skills involving tasks performed by people in their everyday lives.
Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of deleterious mental conditions. These include various matters related to mood, behaviour, cognition, and perceptions.
Sanism, saneism, mentalism, or psychophobia refers to the systemic discrimination against or oppression of individuals perceived to have a mental disorder or cognitive impairment. This discrimination and oppression are based on numerous factors such as stereotypes about neurodiversity. Mentalism impacts individuals with autism, learning disorders, ADHD, FASD, bipolar, schizophrenia, personality disorders, stuttering, tics, intellectual disabilities, and other cognitive impairments.
The lunatic asylum, insane asylum or mental asylum was an early precursor of the modern psychiatric hospital.
The Idiots Act 1886 was an act of Parliament of the United Kingdom. It was intended to give "... facilities for the care, education, and training of Idiots and Imbeciles".
This disability rights timeline lists events outside the United States relating to the civil rights of people with disabilities, including court decisions, the passage of legislation, activists' actions, significant abuses of people with disabilities, and the founding of various organizations. Although the disability rights movement itself began in the 1960s, advocacy for the rights of people with disabilities started much earlier and continues to the present.
Psychopathy, from psych and pathy, was coined by German psychiatrists in the 19th century and originally just meant what would today be called mental disorder, the study of which is still known as psychopathology. By the turn of the century 'psychopathic inferiority' referred to the type of mental disorder that might now be termed personality disorder, along with a wide variety of other conditions now otherwise classified. Through the early 20th century this and other terms such as 'constitutional (inborn) psychopaths' or 'psychopathic personalities', were used very broadly to cover anyone who violated legal or moral expectations or was considered inherently socially undesirable in some way.
The Mental Deficiency Act 1913 was an act of Parliament of the United Kingdom creating provisions for the institutional treatment of people deemed to be "feeble-minded" and "moral defectives". "It proposed an institutional separation so that mental defectives should be taken out of Poor Law institutions and prisons into newly established colonies."
The rights of mental health patients in New Zealand are covered in law by both the New Zealand Bill of Rights Act 1990 and The Code of Health and Disability Service Consumers' Rights. Section 11 of the Bill of Rights Act states that "everyone has the right to refuse to undergo any medical treatment". However the Mental Health Act 1992 allows for the compulsory treatment of patients with major mental illness who do not consent. This legislation also allows for the detention and treatment of individuals who have committed crimes but who have either been deemed unfit to plead or have been found not guilty by reason of insanity.
