Delirium, also known as acute confusional state, is an altered level of consciousness that develops over a short period and fluctuates over time.[2] There may be changes in attention, activity, awareness, sleep patterns, and ability to think.[1] Onset is typically over hours to days and the person differs from their usual baseline mental functioning.[1] In hospital, the condition typically lasts about a week, though some may have ongoing problems afterwards.[1]

Delirium may be caused by a medical condition, medications, substance intoxication, or substance withdrawal.[2] Often a number of factors are involved.[2] Risk factors include dementia, vision problems, hearing problems, and alcoholism.[2] Medications that may trigger the event include benzodiazepines, antihistamines, opioids, and antipsychotics.[2] Other triggers may include infections, pain, or surgery.[2] The underlying mechanism poorly understood.[2]

Diagnose requires establishing a person's usual mental function.[2] The person's activity may be increased (agitation), decreased (subdued), or be a mix of both.[3] Cases were activity is decreased are more frequently missed or attributed to depression.[3] It should be distinguished from psychotic disorders, acute stress disorder, and dementia.[1]

Treatment is generally directed at the underlying causes.[2] Other measures may include hearing aids, glasses, sufficient fluids to drink, a quiet sleep environment, and a visible clock.[2] While antipsychotics are used, there is no evidence to support a benefit for delirium.[2][5][6] Delirium in hospitalized people; however, can be reduced by systematic good general care.[4] About 40% of people with delirium in hospital die within a year.[1]

Delirium affects about 1 to 2% of people overall.[1] Among older adults, rates are around 20% after surgery or when visiting the emergency department, and up to 90% in the intensive care unit.[1][2] Rates around 20% are also seen among those admitted to hospital.[1] The condition becomes more common with age, affecting about 14% of those over the age of 85.[1] Descriptions of delirium date back to at least Hippocrates around 400 BC.[7]
