The symptom cluster of agitation, confusion, disorientation, visual hallucinations, and tachycardia is characteristic of which acute syndrome?

• A. Delirium
• B. Panic attack
• C. Mania
• D. Depression with melancholia

Answer: (A)

Delirium is an acute confusional state in which there is a sudden disturbance of attention and awareness, with fluctuating levels of consciousness and working memory problems. The blend of agitation, confusion, disorientation, visual hallucinations, and tachycardia fits this picture, because delirium often presents with perceptual disturbances (like visual hallucinations) and autonomic signs due to the body’s stress response to an underlying medical or substance-related issue. The onset is abrupt and symptoms can change over hours to days, which helps distinguish delirium from more chronic psychiatric conditions. In contrast, a panic attack centers on intense fear and autonomic arousal with preserved orientation, mania features elevated mood and decreased need for sleep, and depression with melancholia involves persistent low mood and psychomotor changes rather than acute confusion. So the described cluster most accurately reflects delirium.
