The 28 pages that link to Delirium, each with the reason it gives.

• AtropineRelated: Atropine can cause central confusion or delirium, especially at high doses and in older adults.

• DementiaCompared with: Its rapid onset and fluctuating attention differ from the usual gradual course of dementia.

• HallucinationRelated: Hallucinations may accompany delirium and signal an urgent change in brain function.

• DelusionCompared with: Delirium can produce transient false beliefs, but its defining disturbance is acute inattention and altered awareness.

• Hepatic encephalopathyCompared with: Both can cause confusion, so clinicians assess liver disease alongside other causes of delirium.

• Mental status examinationRelated: Inattention and changing alertness on examination can signal delirium and the need to investigate medical causes.

• EncephalitisCompared with: Delirium can resemble encephalitis clinically but does not identify its cause.

• AmnesiaCompared with: Confusion and inattention can resemble memory loss but are central features of delirium.

• Post-intensive care syndromeRelated: Delirium during intensive care is associated with later cognitive and psychological difficulties.

• Near-death experienceCompared with: Critical illness can cause delirium, which may overlap with or differ from near-death reports.

• End-of-life careRelated: Recognizing delirium helps teams relieve distress and assess reversible causes.

• AnticholinergicRelated: Central anticholinergic effects can precipitate or worsen acute confusion.

• CatatoniaCompared with: Delirium can coexist with catatonia, but its defining disturbance of attention differs.

• Cognitive impairmentCompared with: Its sudden onset and fluctuating attention distinguish it from many chronic forms of impairment.

• DiphenhydramineRelated: High doses and heightened sensitivity can make diphenhydramine a cause of acute confusion.

• Intensive care medicineRelated: It is common in intensive care and can complicate treatment and recovery.

• Anticholinergic syndromeBroader topic: Central acetylcholine blockade can produce this dangerous cognitive presentation.

• AripiprazoleCompared with: Unlike the conditions above, delirium is not a standard indication for aripiprazole.

• Altered state of consciousnessRelated: It is a clinically concerning alteration, unlike states sought for practice or exploration.

• HaloperidolRelated: Haloperidol may be used to manage dangerous agitation in delirium, though it does not treat the underlying cause.

• Hip fractureRelated: Older patients with hip fractures are vulnerable to delirium during hospitalization and recovery.

• Psychomotor agitationRelated: New agitation with inattention or confusion can signal delirium and require urgent medical evaluation.

• LethargyCompared with: Lethargy can accompany delirium, but delirium specifically involves impaired attention and awareness.

• GeriatricsBroader topic: Rapid recognition matters because delirium can signal an urgent underlying problem.

• Neurodegenerative diseaseCompared with: Its rapid, potentially reversible changes differ from progressive neurodegenerative decline.

• NeuropsychiatryBroader topic: It illustrates how brain dysfunction can rapidly alter cognition and behavior.

• Frailty syndromeRelated: Frailty increases susceptibility to delirium during acute illness and hospitalization.

• Ganser syndromeCompared with: Medical causes of altered awareness must be considered before attributing confusion to a dissociative condition.
