Alcohol Use Disorder

Alcohol Use Disorder (AUD) is a chronic relapsing brain disorder characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. It involves a spectrum of severity from mild to severe, defined by physiological, behavioral, and cognitive changes.

The etiology is multifactorial, involving a complex interplay of genetic predisposition (heritability estimated at 50%), neurobiological adaptations, and environmental triggers, including childhood trauma, early initiation of alcohol use, and high-stress environments.

AUD involves dysregulation of the brain's reward system, particularly the mesolimbic dopamine pathway. Chronic ethanol consumption alters GABAergic and glutamatergic signaling, leading to neuroplastic changes. Over time, the prefrontal cortex—responsible for executive function and impulse control—becomes impaired, while the amygdala becomes sensitized, driving anxiety and cravings during abstinence.

AUD is a global health issue with a lifetime prevalence of approximately 29% in the United States. It is more common in males, although the gender gap is narrowing. Onset typically occurs in late adolescence or early adulthood.

• Family history of AUD
• Early age of onset of drinking
• Comorbid psychiatric disorders (anxiety, depression, bipolar)
• Impulsivity and sensation-seeking traits
• Social/cultural availability of alcohol
• History of trauma or adverse childhood experiences (ACEs)

A. Early Symptoms

• Increased tolerance


• Social withdrawal


• Continued use despite relationship problems B. Common Symptoms


• Strong cravings


• Inability to limit consumption


• Neglecting responsibilities


• Spending excessive time obtaining or recovering from alcohol C. Advanced Symptoms


• Withdrawal symptoms upon cessation


• Physical manifestations of organ damage


• Social and occupational functioning failure D. Emergency Symptoms


• Delirium tremens (hallucinations, tremors, confusion)


• Seizures


• Unconsciousness or alcohol poisoning


• Hematemesis (GI bleeding)

• Hepatomegaly or jaundice
• Spider angiomas, palmar erythema
• Tremor (hand/tongue)
• Tachycardia and hypertension
• Peripheral neuropathy
• Ataxia (cerebellar degeneration)

A. Clinical Assessment: Use of DSM-5 diagnostic criteria (11 items).
B. Laboratory Testing: Evaluation of liver enzymes and biomarkers.
C. Imaging Studies: MRI for suspected Wernicke-Korsakoff syndrome.
D. Functional Tests: Cognitive screening (MMSE).
E. Biopsy Findings: Liver biopsy if cirrhosis is suspected.
F. Genetic Testing: Not standard clinical practice.
G. Differential Diagnosis: Anxiety disorders, Bipolar disorder, other substance use disorders.

Test Name: Gamma-glutamyl transferase (GGT)
Type: Blood Test
Purpose: Screen for chronic alcohol consumption.
Expected Findings: Elevated levels.
Interpretation: High sensitivity for heavy drinking. Test Name: Carbohydrate-deficient transferrin (CDT)
Type: Blood Test
Purpose: Detection of chronic alcohol intake.
Expected Findings: Elevated.
Interpretation: Highly specific for heavy drinking over 2-3 weeks.

• Ultrasound: Assessment of fatty liver or cirrhosis.
• MRI Brain: Evaluation of cerebral atrophy or Wernicke encephalopathy.

• Sedative-hypnotic withdrawal
• Primary psychiatric disorders
• Liver disease (non-alcoholic)
• Nutritional deficiency syndromes

• Liver cirrhosis, alcoholic hepatitis
• Wernicke-Korsakoff syndrome
• Cardiomyopathy
• Pancreatitis
• Increased risk of esophageal and liver cancer

A. Lifestyle Modifications: Alcohol abstinence, nutritional counseling, social support groups.
B. Preventive Measures: Early screening (SBIRT).
C. Medical Treatment:

• Naltrexone (Opioid antagonist; reduces cravings)


• Acamprosate (GABA/Glutamate modulator; restores balance)


• Disulfiram (Aldehyde dehydrogenase inhibitor; deters consumption)

Prognosis varies; 30-50% experience long-term recovery with appropriate interventions. Relapse is common and considered part of the disease process.

Public policy interventions, brief counseling (SBIRT) in primary care, and early identification of high-risk behaviors.
