Delirium (formerly acute confusional state, an ambiguous term that is now discouraged) [1] is a specific state of acute confusion attributable to the direct physiological consequence of a medical condition, effects of a psychoactive substance, or multiple causes, which usually develops over the course of hours to days.

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.
Exhaustion alone, without syncope or delirium, can prevent a mother from helping a dying infant; in clandestine labors, it can be fatal to the new-born, without mens rea.
