Let an agent explain delirium and its forms in general terms from clinical guidelines, describe causes, recognition and management, present the excited delirium controversy with attribution, and route anyone affected to urgent medical care.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain delirium and its forms in general terms from clinical guidelines, describe causes, recognition and management, present the excited delirium controversy with attribution, and route anyone affected to urgent medical care.

An acute disturbance of attention, awareness and cognition that develops over hours or days and fluctuates, caused by medical conditions, drugs, withdrawal or surgery, presenting as hyperactive, hypoactive or mixed forms, including delirium tremens from alcohol withdrawal, drug-induced delirium and subacute forms; delirium is common in hospitalised older people, is a medical emergency signalling an underlying cause, and is treated by addressing the cause and supportive care, while the term excited delirium is contested and rejected by several medical bodies.

What it is for: Not applicable; a clinical syndrome.

It can be explain the syndrome and forms; relay causes and management; present contested terms with attribution; route to urgent care.

Distinguishing features

Acute onset and fluctuation

Inattention

Underlying cause

Preventable in part

What it looks like

Not a visible object; acute confusion and altered awareness.

Physical character

prevalence in hospitalised older adults: about 20-30 percent - estimates

ICU delirium prevalence: up to about 80 percent - ventilated patients

How it is recognised

Acute fluctuating confusion

Hyperactive, hypoactive, mixed, delirium tremens, drug-induced

Dementia is chronic; psychosis has other features; excited delirium is a contested label

What the second pass must settle

  • How should guidelines be linked?
  • The registry entry has merged aliases including a contested term; should it be annotated or split off?
