Disorders

  1. Substance Intoxication Delirium
  2. Substance Withdrawal Delirium

Recording Procedures

A diagnosis of Substance-Induced Delirium begins with the name of the specific substance (rather than the class of substances) that is presumed to be causing the delirium (e.g., "Diazepam" rather than "Sedative, Hypnotic, or Anxiolytic"). For substances that produce intoxication or withdrawal, the name of the substance is followed by the context in which the symptoms developed (e.g., Dextroamphetamine Intoxication Delirium; Alcohol Withdrawal Delirium). For medication side effects and toxin exposure, the term "-Induced" is used (e.g., Digitalis-Induced Delirium). When more than one substance is judged to play a significant role in the development of the delirium, each should be listed separately. If a substance is judged to be the etiological factor but the specific or class of substances is unknown, the diagnosis is Unknown Substance-Induced Delirium.

Specific Substances

Substance Intoxication Delirium can occur with the following classes of substances: alcohol; amphetamines and related substances; cannabis; cocaine; hallucinogens; inhalants; opioids; phencyclidine and related substances; sedatives, hypnotics, and anxiolytics; and other or unknown substances. Substance Withdrawal Delirium can occur with the following classes of substances: alcohol (often called "delirium tremens"); sedatives, hypnotics, and anxiolytics; and other or unknown substances.

Medications reported to cause delirium include anesthetics, analgesics, antiasthmatic agents, anticonvulsants, antihistamines, antihypertensive and cardiovascular medications, antimicrobials, antiparkinson drugs, corticosteroids, gastrointestinal medications, muscle relaxants, and psychotropic medications with anticholinergic side effects. Toxins reported to cause delirium include anticholinesterase, organophosphate insecticides, carbon monoxide, carbon dioxide, and volatile substances such as fuel or paint.
