Cognitive disorders and delirium can be upsetting to the patient's family and caregivers.

Cognitive disorders and delirium can be upsetting to the family and caregivers, and may be dangerous to the patient if judgment is affected. These conditions can cause the patient to act unpredictably and sometimes violently. Even a quiet or calm patient can suddenly experience a change in mood or become agitated, requiring increased care. The safety of the patient, family, and caregivers is most important.

Cognitive disorders and delirium may affect physical health and communication.

Patients with cognitive disorders or delirium are more likely to fall, be incontinent (unable to control bladder and/or bowels), and become dehydrated (drink too little water to maintain health). They often require a longer hospital stay than patients without cognitive disorders or delirium.

The confused mental state of these patients may hinder their communication with family members and the healthcare providers. Assessment of the patient's symptoms becomes difficult and the patient may be unable to make decisions regarding care. Agitation in these patients may be mistaken as an expression of pain. Conflict can arise among the patient, family, and staff concerning the level of pain medication needed.
