What is Acute Delirium — Emergency Evaluation?

Delirium is a transient global cerebral dysfunction caused by an underlying medical condition. Hyperactive, hypoactive and mixed forms exist; hypoactive delirium is frequently missed in the emergency department.

Common causes include infection (urinary tract, pneumonia, sepsis), drug intoxication or withdrawal, metabolic and electrolyte disturbance, hypoxia, intracranial pathology, and post-anaesthetic state.

Rapid screening tools (CAM, CAM-ICU, 4AT) identify delirium and trigger systematic workup. Untreated delirium increases mortality, length of stay and long-term cognitive decline.
