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. Ranging from mild to severe based on 11 DSM-5 criteria, chronic ethanol exposure induces profound neurochemical neuroadaptations: allosterically enhancing inhibitory gamma-aminobutyric acid (GABA-A) receptors while chronically downregulating and uncoupling excitatory N-methyl-D-aspartate (NMDA) glutamate receptors. Grounded in addiction medicine, the Alcohol Use Disorder Psychoeducation Module delivers 21 structured video lessons on ethanol pharmacokinetics, Kindling mechanisms, life-threatening Delirium Tremens (DTs), and evidence-based anticraving pharmacotherapies.

Alcohol Withdrawal and The Lethal Risk of Delirium Tremens

Unlike opioid withdrawal (which is intensely miserable but rarely fatal in healthy adults), unsupervised abrupt alcohol cessation can be fatal. Abrupt ethanol removal leaves an upregulated, hypersensitive glutamatergic excitatory system completely unopposed by downregulated GABA inhibition. This causes massive excitotoxicity, autonomic hyperactivity (severe hypertension, tachycardia, diaphoresis), withdrawal seizures, and Delirium Tremens (DTs) (severe disorientation, visual/tactile hallucinations, hyperthermia). Medically supervised inpatient detoxification with long-acting benzodiazepines (e.g., chlordiazepoxide or diazepam) on a CIWA-Ar protocol is medically imperative.

The Kindling Phenomenon & Modern Maintenance Medications

  • Kindling: Each repeated cycle of alcohol withdrawal causes progressive, cumulative neurological damage, lowering seizure thresholds and intensifying future withdrawal severity.
  • Acamprosate: Modulates hyperactive glutamatergic NMDA neurotransmission to reduce post-acute protracted withdrawal distress.
  • Naltrexone: Blocks mu-opioid receptors to blunt the euphoric dopamine surge of drinking (effective for the Sinclair Method).
  • Disulfiram: Irreversibly inhibits aldehyde dehydrogenase, causing toxic acetaldehyde accumulation if alcohol is consumed.
