Delirium is a state of mental confusion that can occur as a result of illness, surgery or with the use of some medications. Also called “acute confusional state, stress and lipitor ” delirium usually starts suddenly and can be frightening for the person experiencing it, as well as for those around them.
Symptoms of delirium
Some symptoms are common to delirium, irrespective of cause, while some are cause-specific.
Some examples of symptoms include:
- Diminished awareness of surroundings
- Uncertainly about location
- Inability to understand conversation and speak clearly
- Vivid, often frightening dreams that continue once awake
- Auditory hallucination
- Agitation and restlessness

Causes and risks associated with delirium
Delirium is fairly common among hospitalized patients, with around 1 in 10 having a period of delirium. Delirium is more common among older people, those with memory problems, in cases of dementia, after surgery, after brain injury and in those with poor hearing or vision.
Some of the most common causes of delirium include:
- Infection of the bladder, chest or brain
- Medication side effect
- Liver or kidney problems

- The patients is extremely anxious
