Drug Intoxication
Substance intoxication is a transient condition of altered consciousness and behavior associated with recent use of a substance. It is often maladaptive and impairing, but reversible. If the symptoms are severe, the term "substance intoxication delirium" may be used. Substance intoxication may often accompany a substance use disorder (SUD); if persistent substance-related problems exist, SUD is the preferred diagnosis. The term "intoxicated", used by laymen, most often refers to alcohol. Classification The ICD-10 ''Mental and Behavioural Disorders due to psychoactive substance use'' shows: *F10. alcohol *F11. opioids *F12. cannabinoids *F13. sedatives and hypnotics *F14. cocaine *F15. caffeine *F16. hallucinogens *F17. tobacco *F18. volatile solvent *F19. multiple drug use and use of other psychoactive substances Caffeine The discussion over whether the coffee (caffeine) “buzz” counted as intoxication or not was hotly debated during the early to mid 16th century. ...

Medical State
Medical state is a term used to describe a hospital patient's health status, or condition. The term is most commonly used in information given to the news media, and is rarely used as a clinical description by physicians. Two aspects of the patient's state may be reported. The first aspect is the patient's current state, which may be reported as "good" or "serious," for instance. Second, the patient's short-term prognosis may be reported. Examples include that the patient is improving or getting worse. If no immediate change is expected, the term stable is frequently-used as a qualifier to denote conditions where a patient has stable vital signs. United States A wide range of terms may be used to describe a patient's condition in the United States. The American Hospital Association advises physicians to use the following one-word conditions in describing a patient's condition to those inquiring, including the media. American Hospital Association; (2003-02-01). AHA: Advisory: HIPA ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedatives
A sedative or tranquilliser is a substance that induces sedation by reducing irritability or excitement. They are CNS depressants and interact with brain activity causing its deceleration. Various kinds of sedatives can be distinguished, but the majority of them affect the neurotransmitter gamma-aminobutyric acid (GABA). In spite of the fact that each sedative acts in its own way, most produce relaxing effects by increasing GABA activity. This group is related to hypnotics. The term ''sedative'' describes drugs that serve to calm or relieve anxiety, whereas the term ''hypnotic'' describes drugs whose main purpose is to initiate, sustain, or lengthen sleep. Because these two functions frequently overlap, and because drugs in this class generally produce dose-dependent effects (ranging from anxiolysis to loss of consciousness) they are often referred to collectively as ''sedative-hypnotic'' drugs. Sedatives can be used to produce an overly-calming effect (alcohol being the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classical Conditioning
Classical conditioning (also known as Pavlovian or respondent conditioning) is a behavioral procedure in which a biologically potent stimulus (e.g. food) is paired with a previously neutral stimulus (e.g. a triangle). It also refers to the learning process that results from this pairing, through which the neutral stimulus comes to elicit a response (e.g. salivation) that is usually similar to the one elicited by the potent stimulus. Classical conditioning is distinct from operant conditioning (also called instrumental conditioning), through which the strength of a voluntary behavior is modified by reinforcement or punishment. However, classical conditioning can affect operant conditioning in various ways; notably, classically conditioned stimuli may serve to reinforce operant responses. Classical conditioning was first studied in detail by Ivan Pavlov, who conducted experiments with dogs and published his findings in 1897. During the Russian physiologist's study of digestion, Pav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
