Substance-induced delirium is a type of delirium caused mostly by Anticholinergic drugs and medications. This type of delirium is separate from the delirium in elderly and older people above 65 years of age, and is characterized by shorter duration (usually several hours), and the symptoms are highly influenced by the type of drug and amount consumed.

Delirium, a medical problem which is mainly present in older people with Dementia, is a general, ambiguous term for any type of confusion or Encephalopathy. It has many possible causes, but substance induced delirium is mainly caused by an overdose of certain medications.
