Delirium

Delirium: Introduction

Further information about Delirium is below, or review more specific information about these types of Delirium: delirium tremens, Level of consciousness, decreased, Unresponsiveness, Reduced alertness or other types.

A person with delirium has little in the way of rational consciousness. There is no ability to carry on a conversation in any coherent manner, and indeed a delirious person may not even know you are there. True delirium needs to be distinguished from other symptoms such as dementia, delusions, hallucinations, psychosis or dissociation symptoms.

Diagnosis Checklist: Questions your doctor may ask (and why!)

During a consultation, your doctor will use various techniques in their assessment of Delirium. Your doctor may ask several questions when assessing your condition. It is important to remember that your consultation is a two-way process and any extra information you can share with your doctor about your symptoms may help them with their diagnosis. Some of the questions your doctor may ask are listed below:

  • How long have you noticed the delirium? - to determine if acute or chronic. 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 dementia may be more likely.
  • What are the symptoms of the delirium? - e.g. impaired conscious level with onset over hours or days, disorientation in time and/or place, unusually quite, drowsy, agitated, delusions, auditory hallucinations, visual hallucinations.
  • At what time of the day are the symptoms worse? - e.g. symptoms worse in the late afternoon and at night are typical of delirium.
  • Was there a known precipitating factor to the delirium symptoms? - e.g. physical illness, recent surgery, starting a different medication, abstaining from alcohol.
  • History of head injury? - may suggest subdural haematoma, extradural haematoma or concussion.
  • more questions...»

Diagnosis Checklist: Associated symptoms your doctor may ask about (and why!)

Sometimes, other symptoms may be present and may help your doctor analyse your condition. The symptoms your doctor may ask about (in association with Delirium) may include:

  • Symptoms of dementia? - e.g. impaired memory, impaired judgement and thinking, impaired verbal fluency and impaired ability to perform complex tasks. Personality may change, impulse control may be lost and personal care deteriorates. If onset is chronic consider diagnosis of dementia.
  • Symptoms of depression and anxiety? - Depression may exhibit many of the features of delirium and early dementia, especially memory impairment, slowed thinking and lack of spontaneity.
  • Fever? - can suggest any infection that may cause delirium or meningitis, encephalitis, brain abscess or brain hemorrhage.
  • Symptoms of stroke? - e.g. limb weakness or paralysis, facial muscle weakness or paralysis, difficulty with speech and swallow.
  • Headache? - may suggest brain cancer or acute stroke.
  • more symptoms...»
