Psychiatric disorder in the context of "Detainees"

Conversion disorder (CD) was a formerly diagnosed psychiatric disorder characterized by abnormal sensory experiences and movement problems during periods of high psychological stress. Individuals diagnosed with CD presented with highly distressing neurological symptoms such as numbness, blindness, paralysis, or convulsions, none of which were consistent with a well-established organic cause and could be traced back to a psychological trigger. CD is no longer a diagnosis in the WHO's ICD-11 or APA's DSM-5 and was superseded by functional neurologic disorder (FND), a similar diagnosis that notably removed the requirement for a psychological stressor to be present.

It was thought that these symptoms arise in response to stressful situations affecting a patient's mental health. Individuals diagnosed with conversion disorder have a greater chance of experiencing certain psychiatric disorders including anxiety disorders, mood disorders, and personality disorders compared to those diagnosed with neurological disorders.

Detention is the process whereby a state or private citizen holds a person by removing or restricting their freedom or liberty at that time.

Detention can be due to (pending) criminal charges against the individual pursuant to a prosecution or to protect a person or property. Being detained does not always result in being taken to a particular area (generally called a detention center), either for interrogation or as punishment for a crime (see prison). Persons can be detained if they are not allowed to leave a specific jurisdiction (a type of travel ban known as an 'exit ban') or if they are prevented from traveling to or from a specific area or region. An individual may be detained due a psychiatric disorder, potentially to treat this disorder involuntarily. They may also be detained for to prevent the spread of infectious diseases such as tuberculosis.

Disorders of diminished motivation (DDM) are a group of disorders involving diminished motivation and associated emotions. Many different terms have been used to refer to diminished motivation. Often however, a spectrum is defined encompassing apathy, abulia, and akinetic mutism, with apathy the least severe and akinetic mutism the most extreme.

DDM can be caused by psychiatric disorders like depression and schizophrenia, brain injuries, strokes, and neurodegenerative diseases. Damage to the anterior cingulate cortex and to the striatum, which includes the nucleus accumbens and caudate nucleus and is part of the mesolimbic dopamine reward pathway, have been especially associated with DDM. Diminished motivation can also be induced by certain drugs, including antidopaminergic agents like antipsychotics, selective serotonin reuptake inhibitors (SSRIs), and cannabis, among others.

A vehicle-ramming attack, also known as a vehicle as a weapon or VAW attack, is an assault in which a perpetrator deliberately rams a vehicle into a building, people, or another vehicle. According to Stratfor Global Intelligence analysts, this attack represents a relatively new militant tactic that could prove more difficult to prevent than suicide bombings.

Deliberate vehicle-ramming into a crowd of people is a tactic used by terrorists, becoming a major terrorist tactic in the 2010s because it requires little skill to perpetrate, cars and trucks are widely available, and it has the potential to cause significant casualties. Deliberate vehicle-ramming has also been carried out in the course of other types of crimes, including road rage incidents. Deliberate vehicle-ramming incidents have also sometimes been ascribed to the driver's psychiatric disorder.

Disinhibition, also referred to as behavioral disinhibition, is medically recognized as an orientation towards immediate gratification, leading to impulsive behaviour driven by current thoughts, feelings, and external stimuli, without regard for past learning or consideration for future consequences. It is one of five pathological personality trait domains in certain psychiatric disorders. In psychology, it is defined as a lack of restraint manifested in disregard of social conventions, impulsivity, and poor risk assessment. Hypersexuality, hyperphagia, substance abuse, money mismanagement, frequent faux pas, and aggressive outbursts are indicative of disinhibited instinctual drives.

Certain psychoactive substances that have effects on the limbic system of the brain may induce disinhibition.

The Edinburgh Phrenological Society was founded in 1820 by George Combe, an Edinburgh lawyer, with his physician brother Andrew Combe. The Edinburgh Society was the first and foremost phrenology grouping in Great Britain; more than forty phrenological societies followed in other parts of the British Isles. The Society's influence was greatest over its first two decades and declined in the 1840s; the final meeting was recorded in 1870.

The central concept of phrenology is that the brain is the organ of the mind and that human behaviour can be usefully understood in broadly neuropsychological rather than philosophical or religious terms. Phrenologists discounted supernatural explanations and stressed the modularity of mind. The Edinburgh phrenologists also acted as midwives to evolutionary theory and inspired a renewed interest in psychiatric disorder and its moral treatment. Phrenology claimed to be scientific but is now regarded as a pseudoscience as its formal procedures did not conform to the usual standards of scientific method.
