- Anattention
- Disorganized thinking

A patient must possess both features 1 and 2 AND either 3 or 4 to meet delirium criteria

- LFTs (eg hepatobiliary infection)
- Urine analysis (eg UTI)
- CXR (eg pneumonia)
- ?Utox
- ?CT/LP
Differential Diagnosis
- A
- Alcohol
- E
- Electrolyte Abnormalities
- Encephalopathy (hepatic, hypertensive)
- I
- Insulin (hypoglycemia)
- O
- Opiates
- U
- Uremia
- T
- Trauma
- Toxic Exposure
- Thyrotoxicosis
- I
