Alcohol Dependence DSM-IV Diagnostic Criteria A maladaptive pattern of alcohol use, leading to clinically
significant impairment or distress, as manifested by three or more of the following seven criteria, occurring at any time in the same 12-month period: ◦ 1. Tolerance, as defined by either of the following:
a) A need for markedly increased amounts of alcohol to achieve intoxication or desired effect.
b) Markedly diminished effect with continued use of the same amount of alcohol.
◦ 2. Withdrawal, as defined by either of the following: a) The characteristic withdrawal syndrome for alcohol (refer to DSM-IV for
further details). b) Alcohol is taken to relieve or avoid withdrawal symptoms.
◦ 3. Alcohol is often taken in larger amounts or over a longer period than was intended.
◦ 4. There is a persistent desire or there are unsuccessful efforts to cut down or control alcohol use.
◦ 5. A great deal of time is spent in activities necessary to obtain alcohol, use alcohol or recover from its effects.
◦ 6. Important social, occupational, or recreational activities are given up or reduced because of alcohol use.
◦ 7. Alcohol use is continued despite knowledge of having a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by the alcohol (e.g., continued drinking despite recognition that an ulcer was made worse by alcohol consumption).

Alcohol WithdrawalDSM IV Criteria A. Cessation of (or reduction in) alcohol use that has been heavy and
prolonged. B. Two (or more) of the following, developing within several hours to
a few days after Criterion A: ◦ (1) autonomic hyperactivity (e.g., sweating or pulse rate greater than 100) ◦ (2) increased hand tremor ◦ (3) insomnia ◦ (4) nausea or vomiting ◦ (5) transient visual, tactile, or auditory hallucinations or illusions ◦ (6) psychomotor agitation ◦ (7) anxiety ◦ (8) grand mal seizures
C. The symptoms in Criterion B cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
D. The symptoms are not due to a general medical condition and are not better accounted for by another mental disorder. Specify if: With Perceptual Disturbances

3 Stages of WithdrawalStage 1
◦MinorStage 2
◦MajorStage 3
◦Delirium tremens
![Page 7: Alcohol Withdrawal Keri Holmes-Maybank, MD Cathryn Caton, MD, MS MUSC June 21, 2012](https://reader035.vdocuments.mx/reader035/viewer/2022062516/56649da95503460f94a976d2/html5/thumbnails/7.jpg)
Minor SymptomsAppear between 6 and 48 hours after heavy
alcohol consumption decreasesMay occur with significant alcohol blood
levelsInitial symptoms intensify and then diminish
over 24 to 48 hours◦ Headache◦ Tremor◦ Diaphoresis◦ Anxiety and irritability◦ Nausea and vomiting◦ Heightened sensitivity to light and sound◦ Insomnia

Alcoholic HallucinosisNOT delirium tremens Occur within 12-24 hours of
cessationResolve within 24-48 hoursSpecific hallucinationsUsually visualNo globally clouded sensoriumVital signs normal

Delirium TremensMost intense and serious syndrome~ 5% of patients, 5% mortality rateOccurs 48-96 hours after cessationMay last 5 days
◦ Severe agitation◦ Tremor◦ Disorientation◦ Persistent hallucinations◦ Fever ◦ Tachycardia◦ Tachypnea◦ Hypertension◦ Diaphoresis

Risk Factors for DT’sHistory of sustained drinkingHistory of previous DT’s>30 years oldConcurrent illnesses (psych or
medical)Significant withdrawal symptoms
with elevated BALProlonged interval between
cessation and presentation to health care professional

Alcohol Withdrawal SeizuresOccur in up to 25% of withdrawal
episodesGeneralized tonic-clonic
convulsionsUsually occur 12-48 hours after
last drinkMore common after years of
drinking
![Page 12: Alcohol Withdrawal Keri Holmes-Maybank, MD Cathryn Caton, MD, MS MUSC June 21, 2012](https://reader035.vdocuments.mx/reader035/viewer/2022062516/56649da95503460f94a976d2/html5/thumbnails/12.jpg)
Goals of TherapyReduce severity of withdrawal
symptomsPrevent seizuresPrevent DT’sReduce morbidity and mortality
associated with severe alcohol withdrawal

Pharmacological Management
Moderate to severe withdrawal (Stage 2-3)Clinicians disagree on the optimum
medications and prescribing schedulesSedative hypnotic drugs are recommended
as the primary agents for managing DT’s(grade A recommendation).
Benzodiazepines are the treatment of choice based on two major reviews ◦Reduce occurrence of seizures and delirium◦Reduce severity of withdrawal symptoms
![Page 18: Alcohol Withdrawal Keri Holmes-Maybank, MD Cathryn Caton, MD, MS MUSC June 21, 2012](https://reader035.vdocuments.mx/reader035/viewer/2022062516/56649da95503460f94a976d2/html5/thumbnails/18.jpg)
BenzodiazepinesAct on GABA-A receptors,
similarly to alcoholCIWA-A, modified - symptom
triggered short acting lorazepamMany clinicians prefer long acting
diazepam or clonazepam to avoid symptoms and/or worsening of symptoms
Avoid use of long-acting benzos in elderly or liver disease
![Page 19: Alcohol Withdrawal Keri Holmes-Maybank, MD Cathryn Caton, MD, MS MUSC June 21, 2012](https://reader035.vdocuments.mx/reader035/viewer/2022062516/56649da95503460f94a976d2/html5/thumbnails/19.jpg)
Benzodiazepines – Short vs. Long Acting
Agents with rapid onset control agitation more quickly, for example, oral or IV diazepam has a more rapid onset than other agents (level II evidence)
Agents with long duration of action (eg, diazepam) provide a smooth treatment course with less breakthrough symptoms
Agents with shorter duration of activity (eg, lorazepam) may have lower risk when there is concern about prolonged sedation, such as in patients who are elderly or who have substantial liver disease or other serious concomitant medical illness (level III evidence)
The cost of different benzodiazepines can vary considerably.

Benzodiazepines – Symptom Triggered vs. ScheduledSymptom triggered is as effective
as fixed dose therapy Requires significantly less
benzodiazepinesLeads to a more rapid
detoxificationHowever, patients with a CIWA
score of 15 or history of withdrawal seizures need scheduled benzos
