Overview
It is important to do a thorough physical examination to find out the underlying etiology of delirium.
Physical Examination
Delirium symptom changes in severity during it's course. It's essential to assess patient multiple times, as it's easy to miss diagnosis, also features like sundowning can be overlooked if the assessment is not done in towards end of the day.
- General examination
- Systemic examination
General Examination
- Vitals:
- Blood pressure: Malignant hypertension is an important cause of delirium, and blood pressure must be monitored if the patient is non compliant with antihypertension medications.
- Appearance: Cherry red color indicates CO poisoning, the cynosis may indicate respiratory or cardiac pathology. Jaundice may be indicative of hepatic or bilary pathology.
- Temperature: Fever may be indicative of an underlying infection.
- Conscious level: Various levels of arousal can be seen in delirium, ranging from stupor to hperarousal. If the patient appears to have normal arousal level, attention deficit must be accessed which is very commonly seen in delirium.
- Cognitive function using a standardized screening tool, e.g. MoCA, Mental status examination

- Nutritional status: B12 and folate deficiencies can be assessed on physical examination.
- Hydration state: Dehydration as well as an overload of fluids, resulting in hypoxia can cause delirium.
- Infectious foci: Careful examination to rule out conditions such as meningitis, encephalitis, pulmonary consolidation etc.
- Evidence of intoxication or withdrawal for alcohol, and recreational drugs are an important part of delirium work up. Look for tremors, pupil size, needle tracks etc.
- Posture: Decorticate and Decerebrate rigidity.[1]

Systemic Examination
- Neurological examinations: Careful examination must be done to find out neurological causes of delirium, such as cerebrovascular diseases, neurodegenrative disorders such as parkinsonism, alzhimers, and Lewi body dementia etc. Many systemic diseases may show neurological manifestations, e.g.hepatic encephalopathy causes flapping tremors. Overdose and intoxication can also effect the central nervous system, e.g. opiates causes pin point pupils, and respiratory depression.
- Cranial nerve examination
- Brainstem reflexes: Cold calorics, doll’s eyes
- Examination of motor system and reflexes.
- Examination of sensory systems.
- Cerebellar function test: Coordination and gait
- signs of meningeal irritation
- Carotid bruits and venous hums
- Cardiopulmonary examination: Pulse, cardiomegaly
- HEENT: Sinus tenderness, thyroid, tympanic membrane examination.
- GIT: Hepatosleenomegaly, signs of liver failure
