[Delirium-an interdisciplinary challenge]

Delirium is a common and potentially life-threatening disease that often poses major problems for hospitals in terms of care. It mainly affects older patients and is multifactorial, especially in older people. Permanent functional and cognitive impairments after delirium are not uncommon in geriatric patients.

Often, delirious syndromes are not recognized or are misinterpreted. This is especially the case with the hypoactive form of delirium. Various screening and test procedures are available for the detection of delirium, the routine use of which is essential.

In many cases, delirium can be avoided with suitable preventive measures. Above all, nondrug prevention strategies and multidimensional approaches play an important role here. For the drug treatment of delirium in geriatric patients, low-potency, classic and atypical neuroleptics, as well as dexmedetomidine for severe courses are recommended.
