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.
Various vitamins, especially from the B group, are often used during alcohol withdrawal treatment. Sodium oxybate is the sodium salt of gamma-hydroxybutyric acid (GHB). It is used for both acute alcohol withdrawal and medium-to-long-term detoxification. This drug enhances GABA neurotransmission and reduces glutamate levels.
Severe acute withdrawal symptoms such as delirium tremens and seizures rarely occur after 1-week post cessation of alcohol. The acute withdrawal phase can be defined as lasting between one and three weeks. In the period of 3–6 weeks following cessation, anxiety, depression, fatigue, and sleep disturbance are common. [77]
Withdrawal can resemble barbiturate, alcohol, or benzodiazepine withdrawal, as they all have a similar mechanism of action. Discontinuation symptoms include confusion , disorientation , delirium , hallucinations ( auditory and visual ), insomnia , decreased appetite , anxiety , psychomotor agitation , pressured speech , tremor , tachycardia ...
