All of the following are risk factors for delirium except ̧

A. Pain is a well-known risk factor for delirium. Uncontrolled or severe pain can lead to physiological stress, which may trigger or exacerbate delirium, especially in vulnerable populations such as older adults. B. Medication is another significant risk factor for delirium. Certain medications, particularly anticholinergics, benzodiazepines, and sedatives, can cause or worsen delirium, especially when taken in high doses or during the process of withdrawal. C. Infection is a major risk factor for delirium, especially in older adults or critically ill patients. Infections, particularly urinary tract infections or respiratory infections, can lead to inflammation and metabolic disturbances that may precipitate delirium. D. Gender is not considered a direct risk factor for delirium. While delirium can affect individuals of any gender, there is no strong evidence to suggest that gender alone plays a significant role in the development of delirium. The risk factors for delirium are more closely related to medical conditions, medications, and environmental factors rather than gender.
