Unit
- DSM-5 Diagnostic Criteria: Alcohol use disorder is defined by a cluster of symptoms including impaired control, social impairment, risky use, and pharmacological criteria such as tolerance and withdrawal. A diagnosis requires at least 2 of 11 criteria within a 12-month period, with severity classified as mild (2-3), moderate (4-5), or severe (6+).
- Impaired Control: Individuals may consume alcohol in larger amounts or over longer periods than intended, persistently desire to cut down or control use, and spend a great deal of time obtaining, using, or recovering from alcohol.
- Social Impairment: Recurrent alcohol use leads to failure to fulfill major role obligations at work, school, or home; continued use despite persistent social or interpersonal problems caused by alcohol; and important social, occupational, or recreational activities are given up or reduced.
- Risky Use: Recurrent use in situations where it is physically hazardous (e.g., driving while intoxicated), and continued use despite knowledge of a persistent or recurrent physical or psychological problem likely caused or exacerbated by alcohol.
- Pharmacological Criteria: Tolerance is defined by a need for markedly increased amounts of alcohol to achieve intoxication or desired effect, or a markedly diminished effect with continued use of the same amount. Withdrawal is characterized by the characteristic withdrawal syndrome (e.g., autonomic hyperactivity, hand tremor, insomnia) or using alcohol to relieve or avoid withdrawal symptoms.
- Severity Levels: The number of criteria met determines severity: mild (2-3), moderate (4-5), severe (6 or more). Severity guides treatment intensity and monitoring.
- Course Specifiers: Clinicians may specify if the disorder is in early remission (no criteria for 3-12 months) or sustained remission (no criteria for 12+ months), and whether in a controlled environment.
- Differential Diagnosis: AUD must be distinguished from substance use disorders involving other drugs, and from medical conditions that mimic intoxication or withdrawal. Comprehensive assessment includes collateral information and medical evaluation.
- Impact on Functioning: AUD affects multiple domains: physical health (liver disease, cardiovascular issues), mental health (depression, anxiety), social stability, and economic productivity. Recognizing the full impact is essential for holistic management.
- Comorbid Psychiatric Disorders: AUD frequently co-occurs with other mental health conditions such as major depressive disorder, anxiety disorders, post-traumatic stress disorder, and bipolar disorder. Integrated treatment addressing both AUD and comorbid disorders is essential, as untreated psychiatric conditions can undermine recovery and increase relapse risk.
- Screening and Assessment Tools: Standardized instruments like the Alcohol Use Disorders Identification Test (AUDIT) and the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) aid in screening, severity assessment, and withdrawal management. Validated tools improve diagnostic accuracy and help tailor intervention intensity to patient needs.
Terminology
- Alcohol Use Disorder (AUD)
- A chronic relapsing brain disorder characterized by compulsive alcohol use, loss of control over intake, and a negative emotional state when not using. DSM-5 defines AUD as a pattern of alcohol use leading to clinically significant impairment or distress.
- DSM-5
- Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, the standard classification of mental disorders used by mental health professionals in the United States.
- Withdrawal
- A syndrome that occurs when blood alcohol concentrations fall after heavy and prolonged alcohol use, including symptoms such as anxiety, tremor, sweating, and in severe cases, seizures and delirium tremens.
Quick Revision
- AUD is diagnosed using DSM-5 criteria with severity based on number of symptoms.
- Criteria include impaired control, social impairment, risky use, tolerance, and withdrawal.
- Severity levels (mild, moderate, severe) guide treatment planning.
- Differential diagnosis and functional impact assessment are critical components.
