| ==Overview==
| |
| '''Delirium tremens''' (colloquially, the '''DTs''', "'''the horrors'''", "'''the shakes'''" or "'''rum fits'''"; afflicted individuals referred to as "'''jitterbugs'''" in 1930s [[Harlem]] slang; literally, "'''shaking delirium'''" or "'''trembling madness'''" in [[Latin]]) is an acute episode of [[delirium]] that is usually caused by [[withdrawal]] or [[abstinence]] from [[alcoholic beverage|alcohol]] following [[alcoholism|habitual excessive drinking]], or [[benzodiazepines]] or [[barbiturates]] (and other minor tranquilizers).<ref>{{cite journal | journal = Med J Aust | year = 1972 | month = Aug | date = 19 | volume = 2 | issue = 8 | pages = 450 | title = Delirium tremens following withdrawal of nitrazepam | author = Darcy L | pmid = 5086307 }}</ref><ref>{{cite journal | journal = Ann Fr Anesth Reanim | year = 1984 | volume = 3 | issue = 5 | pages = 383-4 | title = [Physical dependence on benzodiazepines in traumatology] | author = Berezak A | coauthors = Weber M, Hansmann J, Tulasne PA, Laporte B, Ould Ouali A | pmid = 6149713 }}</ref> When caused by alcohol, it occurs only in individuals with a history of constant, long-term alcohol consumption. Occurrence due to [[benzodiazepine withdrawal syndrome|benzodiazepine]] or barbiturate withdrawal does not require as long a period of consistent intake of such drugs. Prior use of both tranquilizers and alcohol can compound the symptoms, and while extremely rare, is the most dangerous especially if untreated. Barbiturates are generally accepted as being extremely dangerous, both due to overdose potential and addiction potential including the extreme withdrawal syndrome that usually is marked by delirium tremens upon discontinuation. Due to this, barbiturates are rarely used anymore, being replaced by the generally accepted less dangerous benzodiazepines, which however still cause a similar withdrawal syndrome.{{fact|date=March 2008}}

| Five percent of acute ethanol withdrawal cases progress to delirium tremens.<ref>[http://www.emedicine.com eMedicine The Continually Updated Clinical Reference<!-- Bot generated title -->]</ref> Unlike the withdrawal syndrome associated with [[opiate]] addiction (generally), delirium tremens (and alcohol withdrawal in general) can be fatal. Mortality can be up to 35% if untreated; if treated early, death rates range from 5-15%.<ref>[http://www.emedicine.com/med/topic524.htm eMedicine - Delirium Tremens : Article by Michael James Burns, MD, FACEP, FACP<!-- Bot generated title -->]</ref>

| ==Symptoms==
| |
| The main symptoms are confusion, disorientation and agitation and other signs of severe [[Autonomic nervous system|autonomic]] instability ([[fever]], [[tachycardia]], [[hypertension]]). Other common symptoms include intense [[hallucination]]s such as visions of insects, snakes or rats (or stereotypically, [[Seeing pink elephants|pink elephants]] or [[Glossary_of_psychiatry#Lilliputian_hallucinations|tiny figures]]). These may be related to the environment, e.g., patterns on wallpaper that the patient would perceive as giant spiders attacking him or her. Unlike hallucinations associated with [[schizophrenia]], delirium tremens hallucinations are primarily visual, but associated with tactile hallucinations such as sensations of something crawling on the subject - a phenomenon known as [[formication]]. Delirium tremens can sometimes be associated with severe, uncontrollable [[tremor]]s of the extremities and secondary symptoms such as anxiety, panic attacks and [[paranoia]].
| |
|
| |
| Delirium tremens (DT) should be distinguished from [[alcoholic hallucinosis]], the latter occurring in approximately 20% of hospitalized alcoholics and not carrying a significant mortality. In contrast, DT occurs in 5-10% of alcohol-dependent people and carries up to 5% mortality with treatment and up to 35% mortality without treatment.<ref>[http://www.emedicine.com/EMERG/topic123.htm eMedicine - Delirium Tremens : Article by William G Gossman<!-- Bot generated title -->]</ref> DT is characterized by the presence of altered [[sensorium]]; that is, a complete hallucination without any recognition of the real world. DT has extreme autonomic hyperactivity (high pulse, blood pressure, and rate of breathing), and 35-60% of patients have a fever. Some individuals experience [[seizure]]s.
| |
|
| |
| ==Causes==
| |
|
| |
| Delirium tremens can occur after a period of heavy alcohol drinking, especially when the person does not eat enough food.
| |
| It may also be triggered by head injury, infection, or illness in people with a history of heavy use of alcohol.
| |
|
| |
| It is most common in people who have a history of alcohol withdrawal, especially in those who drink the equivalent of 7 - 8 pints of beer (or 1 pint of "hard" alcohol) every day for several months. Delirium tremens also commonly affects those with a history of habitual alcohol use or alcoholism that has existed for more than 10 years.
| |
|
| |
| The exact pharmacology of ethanol is not fully understood: however, it is theorized that delirium tremens is caused by the effect of alcohol on the benzodiazepine-GABA<sub>A</sub>-chloride receptor complex for the inhibitory neurotransmitter [[Gamma-aminobutyric acid|GABA]]. Constant consumption of [[alcoholic beverage]]s (and the consequent chronic sedation) causes a counterregulatory response in the brain in attempt to regain [[homeostasis]].
| |
|
| |
| This causes [[downregulation]] of these [[Receptor (biochemistry)|receptor]]s, as well as an up-regulation in the production of excitatory [[neurotransmitters]] such as norepinephrine, dopamine, epinephrine, and serotonin - all of which further the drinker's tolerance to alcohol and may intensify [[tonic-clonic seizure]]s. When alcohol is no longer consumed, these down-regulated GABA<sub>A</sub> receptor complexes are so insensitive to GABA that the typical amount of GABA produced has little effect; compounded with the fact that GABA normally inhibits [[action potential]] formation, there are not as many receptors for GABA to bind to - meaning that [[sympathetic nervous system|sympathetic]] activation is unopposed. This is also known as an "[[adrenergic]] storm". Effects of this "[[adrenergic]] storm" can include (but are not limited to) [[tachycardia]], [[hypertension]], [[hyperthermia]], [[hyperreflexia]], [[diaphoresis]], [[myocardial infarction|heart attack]], [[cardiac arrhythmia]], [[stroke]], [[anxiety]], [[panic attacks]], [[paranoia]], and [[agitation]].
| |
|
| |
| This is all made worse by excitatory neurotransmitter upregulation, so not only is sympathetic nervous system over-activity unopposed by GABA, there is also more of the [[serotonin]], [[norepinephrine]], [[dopamine]], [[epinephrine]], and particularly [[glutamate]]. Excitory [[NMDA receptor]]s are also upregulated, contributing to the delirium and neurotoxicity (by [[excitotoxicity]]) of withdrawal. Direct measurements of central norepinephrine and its metabolites is in direct correlation to the severity of the alcohol withdrawal syndrome.[http://findarticles.com/p/articles/mi_m0847/is_n4_v13/ai_8276920]
| |
|
| |
| It is possible that [[Psychology|psychological]] (''i.e.'', non-physical) factors also play a role, especially those of [[infection]]s, [[malnutrition]], or other underlying medical disorders - often related to [[alcoholism]].
| |
|
| |
| ==Treatment==
| |
| Pharmacotherapy is symptomatic and supportive. Typically the patient is kept sedated with [[benzodiazepine]]s, such as [[diazepam]] (Valium), [[lorazepam]] (Ativan) or [[oxazepam]] (Serax) and in extreme cases low-levels of antipsychotics, such as [[haloperidol]] or even stronger [[benzodiazepine]]s like [[temazepam]] (Restoril) or midazolam (Versed) until symptoms subside. Older drugs such as [[paraldehyde]] and [[clomethiazole]] were the traditional treatment but these have now largely been superseded by the benzodiazepines, although they may still be used as an alternative in some circumstances. [[Acamprosate]] is often used to augment treatment, and is then carried on into long term use to reduce the risk of relapse. If [[status epilepticus]] is present, [[seizure]]s are treated accordingly. Controlling environmental stimuli can also be helpful, such as a well-lit but relaxing environment to minimise visual misinterpretations such as the visual hallucinations mentioned above.
