PsychiatristA psychiatrist is a physician who specializes in psychiatry. Psychiatrists are physicians and evaluate patients to determine whether their symptoms are the result of a physical illness, a combination of physical and mental ailments or strictly mental issues. Sometimes a psychiatrist works within a multi-disciplinary team, which may comprise clinical psychologists, social workers, occupational therapists, and nursing staff. Psychiatrists have broad training in a biopsychosocial approach to the assessment and management of mental illness.
NeuropsychiatryNeuropsychiatry is a branch of medicine that deals with psychiatry as it relates to neurology, in an effort to understand and attribute behavior to the interaction of neurobiology and social psychology factors. Within neuropsychiatry, the mind is considered "as an emergent property of the brain", whereas other behavioral and neurological specialties might consider the two as separate entities. Those disciplines are typically practiced separately.
Insulin shock therapyInsulin shock therapy or insulin coma therapy was a form of psychiatric treatment in which patients were repeatedly injected with large doses of insulin in order to produce daily comas over several weeks. It was introduced in 1927 by Austrian-American psychiatrist Manfred Sakel and used extensively in the 1940s and 1950s, mainly for schizophrenia, before falling out of favour and being replaced by neuroleptic drugs in the 1960s. It was one of a number of physical treatments introduced into psychiatry in the first four decades of the 20th century.
Psychoactive drugA psychoactive drug, psychopharmaceutical, psychoactive agent, or psychotropic drug is a chemical substance that changes the function of the nervous system and results in alterations of perception, mood, cognition, and behavior. These substances may be used medically, recreationally, for spiritual reasons (for example, by altering one's consciousness, as with entheogens for ritual, spiritual, or shamanic purposes), or for research. Some categories of psychoactive drugs may be prescribed by physicians and other healthcare practitioners because of their therapeutic value.
Involuntary treatmentInvoluntary treatment refers to medical treatment undertaken without the consent of the person being treated. Involuntary treatment is permitted by law in some countries when overseen by the judiciary through court orders; other countries defer directly to the medical opinions of doctors. Some countries have general legislation allowing for any treatment deemed necessary if an individual is unable to consent to a treatment due to lack of capacity, other legislation may specifically deal with involuntary psychiatric treatment of individuals who have been diagnosed with a mental disorder.
NeurophysiologyNeurophysiology is a branch of physiology and neuroscience that studies nervous system function rather than nervous system architecture. This area aids in the diagnosis and monitoring of neurological diseases. Historically, it has been dominated by electrophysiology—the electrical recording of neural activity ranging from the molar (the electroencephalogram, EEG) to the cellular (intracellular recording of the properties of single neurons), such as patch clamp, voltage clamp, extracellular single-unit recording and recording of local field potentials.
PsychosocialThe psychosocial approach looks at individuals in the context of the combined influence that psychological factors and the surrounding social environment have on their physical and mental wellness and their ability to function. This approach is used in a broad range of helping professions in health and social care settings as well as by medical and social science researchers. Adolf Meyer in the late 19th century stated that; "We cannot understand the individual presentation of mental illness, [and perpetuating factors] without knowing how that person functions in the environment.
