Which demographic is the condition of delirium most commonly diagnosed in?

1. Middle-aged adults

2. Older adults

3. Children

4. Young adults

The correct answer is: Older adults

Delirium is most commonly diagnosed in older adults due to several factors associated with aging. As individuals age, they become more susceptible to various medical conditions, medication side effects, and physiological changes that can influence cognitive function. Older adults often have multiple comorbidities, are more likely to be hospitalized, and may be experiencing polypharmacy, all of which increase the risk for delirium. Additionally, older adults may have a decreased reserve capacity in cognitive function, making them more vulnerable to acute changes resulting from infections, metabolic imbalances, or changes in their environment. Understanding this demographic's susceptibility is crucial for healthcare providers, as timely recognition and management of delirium can significantly impact outcomes in older patients.
