Delirium is characterized by an altered conscious state with impaired cognition. Intoxication with a variety of agents may present with agitation and delirium.Â The alteration in CNS function is usually a transient direct toxic effect that resolves along with other features of intoxication.Â Secondary complications or concomitant medical emergencies may contribute to altered CNS function.
