Delirium, which is usually a sign of a newly developed disorder, affects about one third of hospitalized people aged 70 or older. Delirium may be distinguished from psychosis , in which consciousness and cognition may not be impaired (however, there may be overlap, as some acute psychosis, especially with mania, is capable of producing delirium states). Factors associated with a higher risk of delirium include advanced or very young age, pre-existing brain trauma (eg, dementia, cerebrovascular disease, tumor, etc.), alcohol dependence, diabetes mellitus, cancer, sensory impairment (eg, blindness or poor hearing), malnutrition, and a history of delirium. Delirium is common in the United States. Delirium is present in 10-22% of elderly patients at the time of admission, with an additional 10-30% of cases developing after admission. Delirium has been found in 40% of patients admitted to intensive care units. Medications may be required to control aggressive or agitated behaviors or behaviors that are dangerous to the person or to others. Antipsychotics are the treatment of choice for distressing symptoms although ones with minimal anticholinergic activity, such as haloperidol or risperidone are preferable.
