Which symptom is listed as a core component of delirium?

• A. Inattention
• B. Anxiety
• C. Depression
• D. Memory loss

Answer: (A)

Delirium is defined by an abrupt change in mental status that includes a disturbance in attention and awareness. Inattention is the hallmark feature because it shows up as difficulty sustaining, shifting, or focusing attention, which leads to confusion and disorganized thinking. The attention disturbance tends to fluctuate over hours to days, helping distinguish delirium from more stable cognitive conditions. Other symptoms may accompany delirium, such as disorganized thinking or fluctuations in alertness, but the defining element remains the impaired attention. Anxiety or depression are mood-related issues and do not capture the acute, fluctuating attention problem. Memory loss can be present in delirium, but it is not the defining criterion; delirium centers on attention and awareness, with possible additional cognitive disturbances. In clinical practice, you can assess attention by asking simple tasks that require concentration or following commands and by observing whether the patient’s focus drifts or waxes and wanes throughout the day. Recognizing the attention deficit promptly is crucial for identifying delirium and initiating investigations for underlying causes.
