  1. May need to get some history from family members and friends
  2. How long have you noticed the delusions?

    Why: to determine if acute or chronic. If acute in nature must consider delirium or a new onset of psychiatric illness as a possible cause of delusion. Delirium is an acute confusional state due to many causes e.g. infection, drug intoxication, alcohol withdrawal, liver failure, kidney failure, hypoxia (reduced oxygen levels in the blood), low blood sugar, stroke, heart attack or head injury. If the onset is chronic a diagnosis of psychiatric illness or dementia may be more likely.

  3. Are the thoughts really delusions?

    Why: delusions are false beliefs that are firmly held despite objective and contradictory evidence, and despite the fact that other members of the culture do not share the same beliefs.

  4. What is the nature of the delusions?

    Why: e.g. grandiose, nihilistic, delusion of reference.

  5. At what time of the day are the symptoms worse?

    Why: e.g. symptoms worse in the late afternoon and at night are typical of delirium.

  6. Was there a known precipitating factor to the delirium symptoms?

    Why: e.g. physical illness, recent surgery, starting a different medication, abstaining from alcohol.

  7. History of head injury?

    Why: may suggest subdural haematoma, extradural haematoma or concussion.

  8. Past psychiatric history?

    Why: e.g. schizophrenia, bipolar affective disorder, paranoid disorder - may be sometimes difficult to differentiate between delirium and these disorders if delusions and hallucinations are present.

  9. Medications?

    Why: certain medications may cause intoxication e.g. anticonvulsants, anticholinergics, anti-anxiety medications, opiates; or may cause delirium on drug withdrawal.

  10. Risk factors for stroke?

    Why: e.g. high blood pressure, high cholesterol, diabetes, smoking, family history - can assess risk of multi-infarct dementia.

  11. Family history of dementia?

  15. Possible poisoning?

    Why: e.g. carbon monoxide, chronic barbiturate intoxication, heavy metals such as mercury and manganese.

  16. Grandiose delusions?

    Why: include beliefs that you have special powers, are chosen by God, or have been sent to save the world. Such beliefs are particularly likely to occur in manic people, but are also found in schizophrenia, dementia and delirium.
