Delirium tremens is a component of alcohol withdrawal hypothesized to be the result of compensatory changes in response to chronic heavy alcohol use. Alcohol positively allosterically modulates the binding of GABA, enhancing its effect and resulting in inhibition of neurons projecting into the nucleus accumbens, as well as inhibiting NMDA ...
Signs and symptoms of alcohol withdrawal occur primarily in the central nervous system. The severity of withdrawal can vary from mild symptoms such as insomnia, trembling, and anxiety to severe and life-threatening symptoms such as alcoholic hallucinosis, delirium tremens, and autonomic instability.
Ethanol (alcohol) has a very similar mechanism of tolerance and withdrawal to benzodiazepines, involving the GABA A receptors, NMDA receptors and AMPA receptors, but the majority of research into kindling has primarily focused on alcohol. [6] An intensification of anxiety and other psychological symptoms of alcohol withdrawal also occurs. [10]
All [citation needed] GABA agonists and positive allosteric modulators of both the GABA-A ionotropic receptor and GABA-B metabotropic receptor subunits, including (partial list): alcohol (alcoholic beverage) (cf. alcohol dependence, alcohol withdrawal, delirium tremens) [11] barbiturates such as phenobarbital, sodium thiopental and secobarbital
The spectrum of alcohol withdrawal symptoms range from such minor symptoms as insomnia and tremulousness to severe complications such as withdrawal seizures and delirium tremens. [12] Alcohol withdrawal syndrome can be very tricky to diagnose, due to other preliminary conditions that may exist from individual to individual.
[1] [2] It can occur during acute intoxication or withdrawal with the potential of having delirium tremens. Alcohol hallucinosis is a rather uncommon alcohol-induced psychotic disorder almost exclusively seen in chronic alcoholics who have many consecutive years of severe and heavy drinking during their lifetime. [3]
A kindling effect also occurs in people with alcohol use disorders whereby each subsequent withdrawal syndrome is more severe than the previous withdrawal episode; this is due to neuroadaptations which occur as a result of periods of abstinence followed by re-exposure to alcohol. Individuals who have had multiple withdrawal episodes are more ...
Delirium may be the result of an underlying medical condition (e.g., infection or hypoxia), side effect of a medication such as diphenhydramine, promethazine, and dicyclomine, substance intoxication (e.g., opioids or hallucinogenic deliriants), substance withdrawal (e.g., alcohol or sedatives), or from multiple factors affecting one's overall ...
